If you have a computer with a printer, you can digital edit pictures of planets (I've done it unprofessionally before, to show that it can be done) complete with fake moons and satellites.

And you can't say CGI because there is footage of all kinds of zero g acrobatics from SkyLab, predates CGI. And wirework couldn't be it either as their movements wouldn't allow for it. Shots are too long for the vomit comet.





As far as CGI goes, have you ever watched the credits for a heavy VFX movie before? There are 100's of people listed under VFX. 100's.

Take the movie 'The Martian':

2015   The Martian
- VFX Shots: 1100   
- VFX Companies: MPC (425 shots), Framestore (338 shots), Industrial Light & Magic (ILM), Milk Visual Effects, Prime Focus World, The Senate Visual Effects and Territory. 700 artists in total.   
- Production Budget: $108,000,000

That doesn't look inexpensive to me.

You do realise if that supposed microgravity was as real as we are told then the person doing those acrobats would have absolutely no way to stop himself from the spin and could not alternate his body, also.

Why?

Same concept:

You mean the concept of insanity? Sitting in a chair twirling a bike wheel is quite rightly just as insane as spinning around in a fake room to convince people gravity is real.

Alright, for like the 70th time, not gravity.

Science experiment time again:

I have a clear jar of water. I have in it water up to halfway and three objects: a small kid's block of wood, a small helium balloon, and a small stone. Rock sinks to bottom, block floats, balloon flies.

It tilt it slowly sideways. Nothing changes about these objects, only the direction of bottom in relation to the container.

Your experiment makes no sense.

In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational analog of linear momentum. It is an important physical quantity because it is a conserved quantity—the total angular momentum of a closed system remains constant. Angular momentum has both a direction and a magnitude, and both are conserved. Bicycles and motorcycles, frisbees,[1] rifled bullets, and gyroscopes owe their useful properties to conservation of angular momentum. Conservation of angular momentum is also why hurricanes[2] from spirals and neutron stars have high rotational.

Its Newtonian, measurable, is calculated, and utilized. Just as an accelerometer in your kindle uses gravity calculations, same goes for angular momentum. engineers use these properties to design and build lots of things. That’s just a cold, hard fact.

Bonus: as mentioned before, the 1973 astronaut in gif #3, a rotating, astair room wouldn’t work, just look at the number of spins he’s doing. No spinning room, no wires, cgi didn’t exist, nothing could replicate that way back then, except 0g. You literally have no counter explanation for it.

I had the explanation from TCM itself, which explain that like the bottle I tilted, there is universal down based on directionality. The bottom of the room changes and the camera catches to to look like he's climbing the walls.

Actually, gravity only goes one way, not toward an object's bottom but toward the ground. So if you're gonna believe in gravity (I don't), you quickly see that behavior of objects is nonetheless governed by placement due to density.

As for the "zero g" room, zero g means when he spins he should go nowhere, but he does have trajectory. Not only that, as explained before, so-called "zero g" can be induced through tricks of motion. Parabolic flight, gravitron, etc. All of these actually do have momentum, it's simply slowed.

Slow-mo was invented early in the 20th century by overcranking or adding more frames. Camera tile has always been known.

This is a gymnast doing cirque d'soleil maneuvers.  Picture one is sideways boosting himself parkour stay across the room (this is why the speed of his body and the ball do not match, he is exerting effort to get across the room.
Picture #2 is also sideways, not that it matters as the room is far more padded than it looks. When he jumps, he could somersault straight to the ground.
Picture #3 is upside and sideways. He's wall jumping because he's a gymnast. In picture #3 you can see how buff this guy is.

The may or may not be "zero g" here (the entire room could spin diff directions in theory), but there is definitely slo-mo and angle shenanigans.

I always focus on the explanation that seems to explain things the easiest.

That I think the guy is a gymnast over there not being gravity here lets you know just how dubious I am that he could casually be in a zero gravity environment.

The longest a vomit comet parabolic 0g experience is 20-30 seconds tops. The gifs I posted are just that, gifs. From the actual source footage they last uncut over a minute+. Cant be a parabolic flight. Obviously no cgi back then

#1: I don’t get your point.
#2: there are several points where he is not moving like a gymnast on high bar. How you just ignore that is dishonest
#3: he literally does 6 somersaults/twists, first pushing off from the left, then back again, 6 more, pushing off from the right. SIX! Do you somehow not see that. How do you do 6 twisting somersaults?

I had the explanation from TCM itself, which explain that like the bottle I tilted, there is universal down based on directionality. The bottom of the room changes and the camera catches to to look like he's climbing the walls.

The problem is the 0g. It doesn't look like they are climbing walls.

And there is no evidence at all of a universal down.

As for the "zero g" room, zero g means when he spins he should go nowhere

WHY?
Stop just asserting nonsense.
Try providing a justification.

as explained before, so-called "zero g" can be induced through tricks of motion.

Like orbiting Earth.

Picture #3 is upside and sideways. He's wall jumping because he's a gymnast. In picture #3 you can see how buff this guy is.

Then why aren't things falling?
Saying it is sideways doesn't help your case at all.

The may or may not be "zero g" here (the entire room could spin diff directions in theory), but there is definitely slo-mo and angle shenanigans.

There is no reason at all to think there are any shenanigans.

Alright, for like the 70th time, not gravity.

It tilt it slowly sideways. Nothing changes about these objects, only the direction of bottom in relation to the container.

Three questions:
How big is your sun?
How "high" is it?
Why doesn't it fall to the ground?
 

The same forces that make your rock "sink" should make your sun sink".

All that you and your fellow Flatties do is criticize established science.  Yet you cannot offer a model that works better.

Listen, I didn't say it was plausible. But that I think it's a gymnast + trick photography over the "obvious explanation" should tell you that I (1) am not trying to BS you, (2) that I genuinely do not believe in zero gravity, and (3) there is something seriously wrong with this video.

I can't even do one somersault. Dude, I can't even do a handstand. But circus acrobats are an occurrence that you can get from two to ten years of specialized training. Meanwhile, in order to get to a zone of zero gravity, that guy has to be chosen as an astronaut, and they have to spend millions to get into space. Not a common occurrence or we'd all be astronauts.  And I'm convinced the only way he would have zero gravity is also not being able to breathe. So no.

Not to mention even if I thought zero g was a thing, we are still accounting for the fact that this guy tosses a ball forward while zooming backward, and grabs something and climbs in midair (crazy coordination hint); swings around on a rope doing several hand-over-hand maneuvers, flipping over before launching off. And then as you say, "he literally does 6 somersaults/twists, first pushing off from the left, then back again, 6 more, pushing off from the right. SIX! Do you somehow not see that. How do you do 6 twisting somersaults?" Zero g doesn't magically make that more doable. In fact, it only raises my suspicion that this guy is some sort of circus freak. No amount of zero g would allow me to hold my legs like that while flipping around, and he changes from somersault to a couple different gymnastic thingies as well. And then more importantly, he sticks the land and bounces off. Right... this guy is totally NOT a circus freak.


CGI is not the be all and end all of camera effects. Well before CGI...

(0:29 they show a space scene, so yeah those are part of effects)

• They had cars driving on superimposed sets as early as black and white era.
• They literally parted the Red Sea.
• Alice in Wonderland growth and shrinking.
• They had several space movies that covered all of the involved things.
• They had Esther Williams apparently underwater for several minutes (yeah right)
• Dancing on the ceiling and invisible people.

I'm just gonna call the whole thing movie magic and not try to explain it.
Because it is easier to make a convincing film than actually launch a person into space for prolonged antigravity stuff.

Don't believe me? Movies do hundreds (around an average of 700 or so, between multiple countries and studios) a year. And even more shows, many of which have special effects.
How many space flights a year? Not as many. 

My point? Follow the money. NASA pays Hollywood to do promo space movies, many of which are very realistic.

Don't ask me how they did the effects. I'm not in showbiz.

I do know that real "gravity" is done by buoyancy and momentum, and that changing directionality shifts objects much like water in a glass bottle. The ground is the ground, and objects fall towards that when they are heavier than their medium.  Nonsense with a guy making six twisting flips is not my thing.


...Here, I typed "Skylab Fake" and I got this.



A wind tunnel. This is how you can breathe while "zero gravity" exists.

Momentum, buoyancy, directionality. Nothing else. Wind speed pushes people into the air, and they slow down the shot so it looks like they are floating vs riding the wind. I knew there was some way this works, and yes, this accounts for it.

Gullible.

I know you don't "believe" in gravity. But sometimes people have to get beyond their belief system and just examine the evidence.

First off, what's this nonsense about not being able to breath in zero g? Where is that coming from? People on the Vomit Comet are laughing, talking...breathing, in the middle of their 15 seconds or so of weightlessness. Hell, that band with the treadmill video, Ok Go, even shot a music video in a vomit comet. They were breathing...

There are no fans in a vomit comet as can be seen. I don't see any evidence of people being subjected to high winds, hair, fabric moving, etc. Try again.

Sometimes you have to park your belief system and just look at the evidence. That is something you seem to be overwhelmingly unwilling to do. Which is a dishonest denial of actual evidence.

If you had even a smidge of evidence to the contrary, that would have to be examined. But you have none. Just loads of speculation without facts. Put your ego aside for a moment and at least provide evidence for, well, anything. Your belief system is an opinion and means nothing in the face of evidence.

Listen, I didn't say it was plausible. But that I think it's a gymnast + trick photography over the "obvious explanation" should tell you that I (1) am not trying to BS you, (2) that I genuinely do not believe in zero gravity, and (3) there is something seriously wrong with this video.

Why should it tell us that?
You might BELIEVE there is something seriously wrong with the video, but that doesn't mean there is one.
You claiming things about it, doesn't give us any reason to think there is anything wrong with the video.
Your excuses for it don't hold up at all.

And I'm convinced the only way he would have zero gravity is also not being able to breathe.

For starters, you are entirely wrong, as gravity does not depend on air.
Things still fall in a vacuum chamber.
In fact, they (appear to) weight more and fall faster.
This is because they don't have the buoyant force from the air pushing them upwards, nor air resistance resisting the fall.
And this can be observed on Earth.

But more importantly, you are again confusing zero gravity and 0g.
Probably because so much of your other crap relies upon this misrepresentation of yours.

They are in orbit. This means they are in free fall. Gravity is still acting on them, accelerating them towards Earth.
But their sideways motion means that they don't get closer to Earth and instead circle it.
And the craft they are in is doing the same.

This means they feel 0g. Not that there is zero gravity.

we are still accounting for the fact that this guy tosses a ball forward while zooming backward, and grabs something and climbs in midair

None of what is in the first clip requires any significant skill.

Do you somehow not see that. How do you do 6 twisting somersaults?

Well when you don't have a time limit from gravity making you hit the ground, you can do a lot.
Likewise, you don't have to deal with your weight when you do things on the bar.

CGI is not the be all and end all of camera effects.

Yet you are still unable to explain these 0g clips.

I'm just gonna call the whole thing movie magic and not try to explain it.

Of course you are. Because it is trivial for you to just dismiss evidence that shows your fantasy is wrong. It would be much harder to try to justify that dismissal of yours.

My point? Follow the money.

You mean the money that goes to building and fuelling rockets?
Building and launching satellites?
And so on.

If you follow the money we see there isn't any to waste on faking space.

I do know that real "gravity" is done by buoyancy and momentum

No, you don't.
That is your baseless assertion which you are yet to justify, which you flee from simple questions which expose it as blind faith.

Something being heavier than air provides no reason for it to move in any direction, nor at any particular rate.
Nor does it give it any justification for the existence of the pressure gradient in the atmosphere nor why things defy this pressure gradient instead of the gradient pushing things upwards.

Conversely, gravity provides a justification for the directionality, it is the direction towards Earth.
It provides a justification for the rate and why the rate varies. The different distance to the mass (including different distances/directions to the slightly non-uniform mass of Earth, with some parts having more mass than others).
It is this force that provides a justification for both why the pressure gradient exists, why this causes an upwards force on objects and why objects can still fall despite that.

...Here, I typed "Skylab Fake" and I got this.

Which you happily accept without thinking about it because you want to.

A wind tunnel.

Which in no way helps explain how those clips works.
If you bothered thinking about it you would easily see this.
Wind is based upon area.
If it was a wind tunnel, when the ball was thrown it would fly upwards.
If it was a wind tunnel, the person would be going all over the place as they change their geometry.

You have found an excuse, so you accept it without thinking because you want it to be fake.

Momentum, buoyancy, directionality.

Does not explain it.

Gullible.

Yes, you are.
You want it to be fake, so you gullibly accept whatever BS some conspiracy nut comes up with to accept it as fake.
You fell for a con.
If you didn't you would recognise that wind doesn't explain it.

I just had visual evidence of people doing similar stunts in a wind tunnel. That you routinely ignore my videos looking for "real evidence" is on you.

And obviously this man is a circus freak. Look at the way he sticks the landing. What? You think gravity being out gives you super powers? Six flips is just as unlikely in "no gravity" as when one is heavier than air. Perfect landing, relaunch, and spin? Yeah this is a complete expert goofing off.

It's either a wind room or they flooded it. Or they generated a vomit effect, as you put it. Or they did special effects.

How Superman flight worked (before CGI).



If something this complicated has been done, you had better believe that groups who want you to believe in Mars flights can do all the fakery needed.

  (2) that I genuinely do not believe in zero gravity
 

 
You don't believe in zero gravity
 Save up your money.  For about $8000 you can take a flight on a civilian "vomit comet" and experience zero g.


BTW, do you believe in gravity?  Most of your fellow flatties don't.

 Save up your money.  For about $8000 you can take a flight on a civilian "vomit comet" and experience zero g.


BTW, do you believe in gravity?  Most of your fellow flatties don't.

From flat earth
flatties, You make the flat earth stationary


Just no poetry in a flat earth….

I just had visual evidence of people doing similar stunts in a wind tunnel.

And you entirely ignored the objections to that, so you can pretend it is all fine.
A wind tunnel will not work for these clips.

And obviously this man is a circus freak. Look at the way he sticks the landing.

And what is so special about the landing which means he is a circus freak?

Six flips is just as unlikely in "no gravity" as when one is heavier than air.

Why?
Yet again, you are just spouting baseless garbage, with no justification at all.
Again, the big difference is time.
You can't do a jump on Earth and do 6 flips in it, because you don't have time to do the 6 flips before you hit the ground.
But in 0 g, you have plenty of time.

That is what makes the big difference, and could allow almost anyone to do 6 or more flips.

It's either a wind room or they flooded it.

A wind tunnel wouldn't work for what is seen, as that depends a lot on the geometry of the object.
Look at the people in the clip you provided going up and down.
If a small ball like was shown in one clip was thrown in a wind tunnel it would fly up.
If a person was doing what your claimed circus freak was doing, in a wind tunnel they would be going up and down all over the place.
Look at how the clothes act in the wind tunnel, and compare it to the clip.

If it was flooded, these people would drown, and the motion would be quite different.

So a wind tunnel clearly wont work, nor would flooding it.

So again, you are just providing whatever excuses you can to dismiss it, and not even bothering to think about it.

Or they generated a vomit effect, as you put it.

Sure, you could say that, by putting them in orbit in space.
i.e. what they say. So no faking required.

The short clip, the one actually in the vomit comet is fine.
But the others are too long.
If you tried that in the Vomit Comet, it would crash into Earth.

How Superman flight worked (before CGI).

Which again looks nothing like what is seen.
Did you even pay attention to what was said?
The actors couldn't move.

So again, you are just looking for excuses to dismiss reality.

windtunnel explains zero-G videos?


AAAAAAAAAAAAh


wind?
directional wind?
directional wind with such a velocity to lift a full grown human off the ground while simultaneously other objects are shown to be flying around in all sorts of directions?
directional wind with such a velocity to lift a full grown human off the ground while simultaneously other objects are shown to be flying around in all sorts of directions AND while it's shown to have no turbulence on the person, their clothes, or their hair?


that's what you're saying?
wind tunnel?
amazing
come now

They're sitting down.  Yes there's a sort of foot anchor but I looked and there doesn't seem to be much real seatbelt. There is nothing actually causing them to rise, despite the man to the left of the seat acting there is (what a bad actor he is).

Nor is there anything causing the man flipping the girls to rise, as he is able to walk about normally.

Lemme explain this. Why zero gravity would mean you suffocate, and what really going on here.

When I say, "It's not gravity, it's buoyancy," I mean that our tendency to fall is a factor of air. Specifically, this means "No gravity, no air." But actually no gravity, and things still fall contrary to fake movies, because the model of gravity is broken. Buoyancy, however continues to work. That is, an area of no gravity, you have to wear a space suit, things ironically fall just fine (I've shown how in airless environments, feathers fall as easily as a rock), and I thought momentum was unhindered by air resistance, but now I dunno. There might be nothing to push off of, resulting in difficult movement. An airless vacuum.
The floating thing? Nah if this were zero gravity, none of them could breathe.

Why isn't their hair moving? Funny, but I'm gonna ask you that for a globe that supposedly rotates at over 1000 mph. But to answer your question, this isn't a directional current here (might be with that video I showed) but rather air evenly pumped so the density of the air is higher than normal, though not crushing. Unlike a wind tunnel I showed where the speed holds you aloft, this has mass not speed. Pressurized air is pumped in at speeds of less than 5mph with the excess sucked out until the air is as thick as water. Like water, they can swim if they want to, or they can sit on the bottom of the pool. The air is roughly as thick, or thicker than water, with the right mix to keep gases in it from being toxic. What this means is there isn't an upward push, or sideways push, or even downward push.

Recall that I said that the laws of buoyancy mean heavier objects fall in light mediums, make you feel under more strain at high altitudes where air is thin, while you can swim in water. This is the opposite, where "water" (and by that, I mean air in this case) is not thick enough to make you outright float but enough that you can swim. It looks slightly more buoyant than water, in fact, as normal water, you cannot run up walls.

This room basically proves my theories. Thank you.

If gravity were real, there wouldn't be so many ways to overcome it.
1. Upward air current
2. Spiral air current
3. High air pressure (equal or greater to water pressure)
4. "Centrifugal force" (circular momentum, e.g. Gravitron),
5. Parabolic momentum
6. Propulsion (what happens to a jumbo jet)
7. Gliding/Flying (normal aerodynamics)
8. Magnets and superconductors
9. Magnets and repulsive force

Gravity doesn't really prevent any of this. Buoyancy not gravity.

Bouyancy?

When the displaced volume-weight is more than the downwards weight of the object.

How much air would you need to offset 150-175lbs of human?

How dense do you think the air would need to be?

Heres a hint - when you swim you float becuae the human body is mostly water.

Quote from: bulmabriefs144 on December 17, 2022, 04:47:39 AM

This is a gymnast doing cirque d'soleil maneuvers.  Picture one is sideways boosting himself parkour stay across the room (this is why the speed of his body and the ball do not match, he is exerting effort to get across the room.
Picture #2 is also sideways, not that it matters as the room is far more padded than it looks. When he jumps, he could somersault straight to the ground.
Picture #3 is upside and sideways. He's wall jumping because he's a gymnast. In picture #3 you can see how buff this guy is.

The longest a vomit comet parabolic 0g experience is 20-30 seconds tops. The gifs I posted are just that, gifs. From the actual source footage they last uncut over a minute+. Cant be a parabolic flight. Obviously no cgi back then

#1: I don’t get your point.
#2: there are several points where he is not moving like a gymnast on high bar. How you just ignore that is dishonest
#3: he literally does 6 somersaults/twists, first pushing off from the left, then back again, 6 more, pushing off from the right. SIX! Do you somehow not see that. How do you do 6 twisting somersaults?

Listen, I didn't say it was plausible. But that I think it's a gymnast + trick photography over the "obvious explanation" should tell you that I (1) am not trying to BS you, (2) that I genuinely do not believe in zero gravity, and (3) there is something seriously wrong with this video.

I can't even do one somersault. Dude, I can't even do a handstand. But circus acrobats are an occurrence that you can get from two to ten years of specialized training. Meanwhile, in order to get to a zone of zero gravity, that guy has to be chosen as an astronaut, and they have to spend millions to get into space. Not a common occurrence or we'd all be astronauts.  And I'm convinced the only way he would have zero gravity is also not being able to breathe. So no.

I know you don't "believe" in gravity. But sometimes people have to get beyond their belief system and just examine the evidence.

First off, what's this nonsense about not being able to breath in zero g? Where is that coming from? People on the Vomit Comet are laughing, talking...breathing, in the middle of their 15 seconds or so of weightlessness. Hell, that band with the treadmill video, Ok Go, even shot a music video in a vomit comet. They were breathing...

Quote from: bulmabriefs144 on December 17, 2022, 09:29:11 AM

Quote from: Stash on December 17, 2022, 05:01:03 AM

Not to mention even if I thought zero g was a thing, we are still accounting for the fact that this guy tosses a ball forward while zooming backward, and grabs something and climbs in midair (crazy coordination hint); swings around on a rope doing several hand-over-hand maneuvers, flipping over before launching off. And then as you say, "he literally does 6 somersaults/twists, first pushing off from the left, then back again, 6 more, pushing off from the right. SIX! Do you somehow not see that. How do you do 6 twisting somersaults?"

Zero g doesn't magically make that more doable. In fact, it only raises my suspicion that this guy is some sort of circus freak. No amount of zero g would allow me to hold my legs like that while flipping around, and he changes from somersault to a couple different gymnastic thingies as well. And then more importantly, he sticks the land and bounces off. Right... this guy is totally NOT a circus freak.

There's no circus freak, now or then, who could do this:

Quote from: bulmabriefs144 on December 17, 2022, 09:29:11 AM

I do know that real "gravity" is done by buoyancy and momentum, and that changing directionality shifts objects much like water in a glass bottle. The ground is the ground, and objects fall towards that when they are heavier than their medium.  Nonsense with a guy making six twisting flips is not my thing.
...Here, I typed "Skylab Fake" and I got this.

A wind tunnel. This is how you can breathe while "zero gravity" exists.

There are no fans in a vomit comet as can be seen. I don't see any evidence of people being subjected to high winds, hair, fabric moving, etc. Try again.

Sometimes you have to park your belief system and just look at the evidence. That is something you seem to be overwhelmingly unwilling to do. Which is a dishonest denial of actual evidence.

If you had even a smidge of evidence to the contrary, that would have to be examined. But you have none. Just loads of speculation without facts. Put your ego aside for a moment and at least provide evidence for, well, anything. Your belief system is an opinion and means nothing in the face of evidence.

I just had visual evidence of people doing similar stunts in a wind tunnel. That you routinely ignore my videos looking for "real evidence" is on you.

And obviously this man is a circus freak. Look at the way he sticks the landing. What? You think gravity being out gives you super powers? Six flips is just as unlikely in "no gravity" as when one is heavier than air. Perfect landing, relaunch, and spin? Yeah this is a complete expert goofing off.

It's either a wind room or they flooded it. Or they generated a vomit effect, as you put it. Or they did special effects.

- There's no wind present and no evidence of a turbine(s) anywhere
- Flooded? There's no evidence of people being underwater, hair not flowing, no kicking feet, etc.
- Vomit Comet doesn't last long enough to support these. But at least you nowe acknowledge that the vomit comet can generate weightlessness - How do you explain that?
- None of the special effects existing at the time would replicate 6 somersaults with pirouettes
- No circus "freak" had ever or has been ever able to perform the movements shown



I'm afraid you're out of excuses. Take in the evidence, digest it, and maybe you'll realize, not matter how much you want something to be fake, that it just isn't. It's about evidence, not speculation.

How Superman flight worked (before CGI).

I've seen this before. Nothing in it is even remotely comparable to the movements achieved in the evidence provided.

They're sitting down.  Yes there's a sort of foot anchor but I looked and there doesn't seem to be much real seatbelt.

You don't need a significant seatbelt to hold you down in 0g.

There is nothing actually causing them to rise

That's right, no fans or anything like that.
Just the experience of 0g.

Nor is there anything causing the man flipping the girls to rise, as he is able to walk about normally.

What makes you say that?
Did you not see the strap on the floor that his foot is latched into as he is spinning the girls before he jumps out of the shot?

Why not focus on the girls?
What is keeping them suspended.

Why zero gravity would mean you suffocate, and what really going on here.

Again, it is not zero gravity. It is 0g. They are in free fall.

And again, vacuum chambers with virtually no air in them, so little that the air acts as discrete particles bouncing around the chamber rather than bulk gas, gravity still exists and things still fall.

When I say, "It's not gravity, it's buoyancy," I mean that our tendency to fall is a factor of air.

And that is wrong.
Instead buoyancy is a result of gravity.

I've shown how in airless environments, feathers fall as easily as a rock

i.e. you have directly contradicted yourself.
In an airless environment, where you claim there is no reason for things to fall because you claim things fall because of air; things still fall.

In reality (i.e. with gravity), air just gets in the way and makes it harder for things to fall, because they need to push the air out of the way, and up above them as they fall.

So air is not the reason things fall.

Why isn't their hair moving? Funny, but I'm gonna ask you that for a globe that supposedly rotates at over 1000 mph.

You mean at one revolution every 24 hours?
They are spinning faster than that in the shot.
Why should the even slower rotation of Earth make a difference?

If they were being supported by wind, their hair should be flying all over the place due to the turbulence.

And as they don't have breathing apparatus, they clearly aren't under water.

Both of your excuses fail.

But to answer your question, this isn't a directional current here (might be with that video I showed) but rather air evenly pumped so the density of the air is higher than normal, though not crushing. Unlike a wind tunnel I showed where the speed holds you aloft, this has mass not speed. Pressurized air is pumped in at speeds of less than 5mph with the excess sucked out until the air is as thick as water. Like water, they can swim if they want to, or they can sit on the bottom of the pool. The air is roughly as thick, or thicker than water, with the right mix to keep gases in it from being toxic. What this means is there isn't an upward push, or sideways push, or even downward push.

The problem with that is that the density would need to match everything inside. Otherwise, you will have some things more dense that your magically thick air, which would then fall, and you would have things less dense than air which rises.

Also, the average density of a human is roughly 1000 kg/m^3.
To get air at that density, you would need to pressurise it to roughly 800 atm, assuming the air remained an ideal gas.
The problem is at those pressure's it wouldn't.
Instead, these pressures are enough to liquify the air.
This is associated with a significant increase in viscosity, but it wouldn't give you the density required to make things float.
Liquid air has a density between 800 and 900 kg/m^3, so a human would still be denser than it.

And there is the issue of the human body not being likely to withstand that pressure.

It looks slightly more buoyant than water, in fact, as normal water, you cannot run up walls.

You can't really run at all in water, due to its viscosity.

This room basically proves my theories. Thank you.

No, it doesn't.
It demonstrates so many faults it isn't funny.

If gravity were real, there wouldn't be so many ways to overcome it.
1. Upward air current
2. Spiral air current
3. High air pressure (equal or greater to water pressure)
4. "Centrifugal force" (circular momentum, e.g. Gravitron),
5. Parabolic momentum
6. Propulsion (what happens to a jumbo jet)
7. Gliding/Flying (normal aerodynamics)
8. Magnets and superconductors
9. Magnets and repulsive force

Why?
Because you say so?

Why don't you try explaining just how any of those refute gravity rather than just asserting more baseless delusional BS?

Yet again, you are just looking for excuses to dismiss gravity, and any excuse will do, regardless of how poor it is or its complete inability to explain what is observed.

So lemme get this straight. You believe that girls with round behinds are instrumental in the rotation of Earth?



And no, I don't believe in gravity.  And those chambers don't prove gravity, they prove you're able to be pranked. Did you leave Earth in order to be hoisted from gravity? No? Then you're showing how it is possible to simulate suspension of gravity within Earth. If you can simulate zero gravity on Earth, by definition, you have disproved the need to go to space.

How much air would you need to offset 150-175lbs of human?

How dense do you think the air would need to be?

As dense as water. The density of water isn't anywhere near sufficient for humans to float outright. But it is dense enough for humans to swim.  All of this trickery looks like swimming, and the man flipping the girls is able to stand on the ground until he wants to climb the wall.  I can do this wall climbing in my pool.

What I can't do in my pool is actually breathe, as water is drinkable but not breathable.



That up and down hand jive reminds me of this.

And no, I don't believe in gravity.  And those chambers don't prove gravity

Things falling in a vacuum demonstrate your ideas are pure nonsense.
And you are yet to provide a viable alternative to 0g from the known mechanics of the vomit comet and a craft in orbit.

Then you're showing how it is possible to simulate suspension of gravity within Earth. If you can simulate zero gravity on Earth, by definition, you have disproved the need to go to space.

No, you haven't.
Beign able to simulate it in an airplane for a short period of time doesn't explain how much longer continuous shots are filmed in space.

As dense as water.

And the issue is that you can't make air that dense.
(and the other issue is that would drastically increase the viscosity).

All of this trickery looks like swimming, and the man flipping the girls is able to stand on the ground until he wants to climb the wall.

Why repeat the same garbage?
I already pointed out that the man flipping the girls has his foot under a strap.

Your excuses don't work.
Why not just accept the real explanation for the vomit comet?

And no, I don't believe in gravity.  And those chambers don't prove gravity, they prove you're able to be pranked. Did you leave Earth in order to be hoisted from gravity? No? Then you're showing how it is possible to simulate suspension of gravity within Earth. If you can simulate zero gravity on Earth, by definition, you have disproved the need to go to space.

So now you believe that we can simulate zero gravity?

And no, not by definition. What you're missing is duration. We can simulate zero gravity, but for a max of about 20 or so seconds. However, in space, the duration is seemingly limitless. Even though you don't agree with it, it's shocking that you don't even understand it from a counter perspective.

The pressure required would liquify air.
And at ambient temperature, that would be too low a density.
While you could try to change the density, that would also change the density of the person you are trying to float.

Obviously no person would survive it



Bit if you can freeze CO2 you can surely compresss air wnough to liquidfy.

Liquid air has a density lower than water, so people would still sink in it.

Of course we can. You can do so, just by going on a ride in an amusement park, and you just told me you could when you mentioned this $8000 vomit comet.

Now you will backpedal and say this is "actually in space". As though you could get into space for only $8000. What you can do is is use parabolic flight.



They admit that it's a way to simulate zero G. Yes, everyone admits this is fake.

But the problem with you is you're like a person watching Star Trek who says after the show, "Yes, but the science of Star Trek is real science." Rather than correctly determining that it's just a show, which btw has crappy special effects. That you can't use suspension of disbelief and move on, but continue to think that the Interstellar movie is about an actual mission is a hangup. Space travel is science fiction, no matter how well it is depicted in film.

Also Star Trek sucks, and you suck for liking it as anything beyond light-hearted parody. Star Wars is the actual science here.



Real science.

There is no duration. If the 20 seconds thing even is a thing (and not something someone told you), it is because of something called homeostasis. That is, if I were to go on a roller coaster ride that simply pulled me to the right (most boring ride ever), I would recoil back against that motion, but after a few moments, the recoil would stop. However, a zig zag ride, where about the point where I start to adjust to the motion, I continue to get whiplash (now it sounds like a painful ride).

Momentum is created by velocity (and mass). Velocity is created by speed and direction. That is, you can maintain motion by constantly changing direction (which you do in a parabola). There is no reason why parabolic flight should have a 20 second time limit. Rotational (gravitron ride) flight has to change direction after 20 seconds or alternate to start with.

You could, and it wouldn't.

It would be harder to breathe thick air, if you actually thickening it.

 But this is just raising the volume of air in the room to an absurd degree, to the point where there is an excess of it, and it is thick. We're not freezing it to thicken it.

 Although I am told that compressed air is colder than regular air, this is air that was compressed through cooling and vacuum packing.

The air we are talking about is simply pumped in at volume.

Pv=nrt

Compresed air is hot.

DEcompressing air is cool.



If the air is as thick as water, which you alluded to as the reason peoplel could 'swim' in space, then it would have to be literally as thick as water.

You said this earlier:

Lemme explain this. Why zero gravity would mean you suffocate, and what really going on here.

So are you the one back-pedaling now saying that the vomit comet is real and people don't suffocate?

And do you lack reading comprehension?

Again, what you're missing is duration. We can simulate zero gravity, but for a max of about 20 or so seconds. However, in space, the duration is seemingly limitless.

Of course we can. You can do so, just by going on a ride in an amusement park, and you just told me you could when you mentioned this $8000 vomit comet.

You sure do love ignoring key parts.

The Vomit Comet, relying upon parabolic flights, has very limited periods of 0g.
If it keeps on going, it crashes into Earth.

While the vomit comet relies upon the same principles (keeping people inside in free fall, and just applying power to the craft to overcome air resistance), the duration is quite limited compared to a craft in orbit.

As for amusement park rides, which rides simulate 0g?

But the problem with you is you're like a person watching Star Trek who says after the show, "Yes, but the science of Star Trek is real science."

No, we aren't.

We understand the science, and understand that you are just looking for excuses to reject reality, to cling your delusional fantasy.

There is no duration.

Again, there is.
If it keeps going, it smashes into Earth.

If the 20 seconds thing even is a thing (and not something someone told you), it is because of something called homeostasis. That is, if I were to go on a roller coaster ride that simply pulled me to the right (most boring ride ever), I would recoil back against that motion, but after a few moments, the recoil would stop.

Pure BS, already contradicted by your prior statements.

Remember the Gravitron ride you have already brought up?
Where you are pushed to the wall.
That is effetively the kind of ride you are describing, where you just turn.
This turning keeps you pressed to the wall.
And it doesn't stop.

So yet again, you just spout delusional nonsense. Any dishonest BS you can to pretend space is fake.

Momentum is created by velocity (and mass).

No, momentum IS mass travelling at velocity. It isn't created by velocity and mass.
Whatever is causing the momentum is causing the velocity. They are "created" by the same thing, a force.

Velocity is created by speed and direction.

Wrong again, velocity IS a speed in a specific direction. It is not created by it.

That is, you can maintain motion by constantly changing direction

And more BS.
If you cosntantly change your direction you likely lose your motion, due to whatever you are doing to change direction having losses.

There is no reason why parabolic flight should have a 20 second time limit.

It isn't quite 20 seconds, but it does have a limit.
The simple reason why is that it will eventually crash into Earth.
If you want to make it go longer, you need it to go higher. Eventually, you will be going into space, and a plane wouldn't be able to do it because planes have a maximum altitude after which their engines can't get the air it needs.

Rotational (gravitron ride) flight has to change direction after 20 seconds or alternate to start with.

And more delusional BS.
It doesn't change direction of rotation.
Another simple example is a centrifuge.
Again, it doesn' need to oscillate. It just keeps spinning in the same direction.

Pv=nrt

Compresed air is hot.

DEcompressing air is cool.

If the air is as thick as water, which you alluded to as the reason peoplel could 'swim' in space, then it would have to be literally as thick as water.

That's funny because I have sprayed a compressed air on my computer and it never feels at all hot.

So are you the one back-pedaling now saying that the vomit comet is real and people don't suffocate?

Define "real." Do you mean the ride exists? Yes it does.

Do you mean you go into space? No, you don't. Any part of the trip is fake that tries to convince you of that.

And by your own admission, you've told me that you wasted $8000 forking over money in order to be indoctrinated. Thanks but I'd like to spend money on what I want. You are an enormous sucker trying to find a greater fool to compensate the fact that you lost $8000 to a scam. Sorry, but you'll need to find some other idiot. I'm not giving NASA anything.

Again, what you're missing is duration. We can simulate zero gravity, but for a max of about 20 or so seconds. However, in space, the duration is seemingly limitless.

I explained earlier why this "limit" exists. Whenever you change direction, you reset the process. If the duration is limitless, it's because they are using parabolic motion to constantly shift direction.

Actual "zero gravity" you fall then you suffocate. If you are breathing normally without a suit, no matter what the outside of the ship looks like, you are not in space.

And do you lack reading comprehension?

Apparently you do. I explained not once but at least twice now about velocity involving direction, and you're not seeing it.

That's funny because I have sprayed a compressed air on my computer and it never feels at all hot.

Great job demonstrating a lack of comprehension yet again.

It is compressed in the can. When you spray it, it gets decompressed.
That results in it cooling down.

If you compress air the opposite happens, with it getting quite hot.

Define "real." Do you mean the ride exists? Yes it does.
Do you mean you go into space? No, you don't.

No one is saying the Vomit Comet goes into space.

The Vomit Comet is limited in the duration of 0g.
Because it needs to follow a parabolic trajectory. If it continued on that trajectory to give you 0g for longer, it will crash into Earth.
If you want a longer time, you need to go into space and orbit Earth.

I explained earlier why this "limit" exists.

You asserted pure nonsense and had it refuted.

Actual "zero gravity" you fall then you suffocate.

"zero gravity" or 0g?
Regardless, you are yet to provide any reason for why you would fall, nor why you would suffocate.

If you are breathing normally without a suit, no matter what the outside of the ship looks like, you are not in space.

Why?
You accept that a suit can allow you to breathe in space. Why can't a space-craft do the same?

Apparently you do. I explained not once but at least twice now about velocity involving direction, and you're not seeing it.

You mean you have asserted pure nonsense, which has been refuted.
