The science and engineering of airplanes and self-driven cars make sense. Both from and engineering and scientific standpoint.

The space fantasies only make sense in the same way that Santa Claus makes sense; "we want it to be true, so it must be true". Unfortunately; I was very disappointed to learn it can only be fake(d).

The science and engineering of space rockets and space travel make sense. Both from and engineering and scientific standpoint. And proven over and over.

The Flat Earth fantasies only make sense in the same way that Santa Claus makes sense; "we want it to be true, so it must be true". Unfortunately for flat earth believers; everything points to the opposite.

Flat Earth is just as trolling and ridiculous as NA$A "science" and "engineering".

Sorry for breaking beliefs.

Rocketry and space travel is not a believe, plenty of physics to support it, if u haven't study it or u don't understand it, that doesn't make it fake.

So... In our solar system which is a planet with a mass able to produce a gravitational field that opposes to sun's ones and makes orbits possible?

Ill try to answer the original question, first do you understand how orbits work, if not learn it from a quick google search.
Second, to be in orbit, the iss has a fast velocity perpendicular to the surface, all people inside have the same velocity. Both the people and the iss are accelerating downwards at the same speed, since both the iss and people have the same acceleration and velocity, they will both follow the same path. If you had an astronaut outside the iss moving at the same velocity as an astronaut inside, he to would follow the iss as well.
A plane is different, consider a plane flying at a constant speed, there is a force from the wings countering gravity, so the plane has no acceleration, but the people inside still accelerate downwards, so the acceleration acting on the plane and people is different, so the people inside the plane move downwards to it's floor.

There was a lot of activity on here after I left last night. I appreciate everyone's thoughts on this subject. I especially want to thank legion because he came to my rescue and defended me. I know everyone is trying to relate me to a child because you all believe what you've been taught and it makes all the sense in the world to you. But to me, not so much. I've been taught the same as most on here but I have a little difficulty believing it.

From what I've gathered, it is the free falling that causes the astronauts to float around inside the ISS. Even though they are falling the same speed. I don't believe this is true. I'm going to attempt to give my reasoning and I hope I can explain it well enough for everyone to understand.

Picture the ISS located at the equator at the very middle of the earth. The earth's diameter is around 8000 miles. That means you are 4000 miles from the edge. The ISS has to travel parallel with the earth for around 14 minutes before it reaches the edge of the earth. The ISS is around 250 mile above the Earth, but it is only around 188 miles from the Kármán line before it starts to enter the earth's atmosphere. If gravity pulls the ISS down, it would only take 38 seconds before it starts to enter earth's atmosphere. Since gravity is the only force acting on the ISS to cause it to go into free fall, it couldn't be in free fall very long and it has to keep traveling parallel to the earth to keep from being pulled to earth. The vision everyone has is that this great big ISS just falls around this little ball earth and everyone is okay with that. My vision is this tiny ISS is flying around this great big earth. To me, it is traveling parallel with the earth all the time and maybe a slight bit of gravity is pulling it so they would have to use rocket thrust to bring it back up over time. But it is not free falling at all. You can watch the videos of the ISS and I don't see it free falling. It is flying parallel and level with the earth just like an airplane would fly around the earth only faster. I'm sure everyone on here has heard or used the story of traveling in an airplane traveling 600 mph and you don't feel the movement at all because you are traveling the same speed as the airplane. Well I use that same argument here. The ISS traveling 17,000 mph and the passengers will not notice it either because they are traveling the same speed as the ISS. That is my reasoning and I hope you can understand what I'm trying to say. You can call it childish thinking if you want, but to me it seems logical and I'm not a child.

I have little hope for you.

I waded back through the thread. I count 7 decent full explanations on how orbit  is acieved and 4 on why that makes astronauts appear to float around complete with links to at least 2 videos. In some posts to the math to calculate such feats of witchcraft are put forth.

You thank Legion, because he appears to share your floored logic and lack of intellect, but he is in fact making a mockery of you. He himself can provide you with a reason on why its not possible to float around on the ISS can he? has he got the facts and figures to prove it? No! Hes just a troll.

I give up on trying to explain facts to someone who doesn't think that facts are believable.

The motion of objects is governed by Newton's laws. FACT

As I said, the astronauts are at the same velocity as the iss, and will have the same acceleration towards the center of the earth as the iss, so since they share the same acceleration and velocity, the astronaut follows the same path as the iss. Hence the astronaut stays stationary relative to the iss, so he floats relative to it.

I hate to say it but, you guys have a lot of book smarts, but little common sense. Or you could figure this out on your own and not have to rely on NASA telling you lies and making a mockery of you. I feel sorry for you because you can't think on your own. Even when I show you what orbit is you still don't understand. There is no free fall in orbit, so why do they float around? If, like in an airplane it is traveling in a straight line the passengers won't feel movement and they certainly won't float out of their seats. Wake up folks and think about it. It is not hard at all. Have you ever seen any videos of the ISS going up and down like the 'vomit comet'. No, it always flies straight and parallel with the earth. This notion they fall around the earth is science fiction and plain old BS and you guys lap it up. When I started this thread and asked the question, "Why do astronauts on board ISS float around", I knew that no one could figure out the lie. You all have proved me right.

P.S.
Legion, I believe this is a win for flat earth.

There's a valid reason why Yendor is puzzled by the actions of this supposed ISS and its supposed orbit around a supposed globe. The reason is because he's intelligent enough to see bullshit when it rears its ugly head so blatantly.
Then you get the globalites jumping on him and trying their best to make him appear child like when they know for a fact that he's questioning because it BEGS questions, which is why Legion is backing him up, because Legion and many other logical people who possess common sense can see that the official explanations are clear and utter made up magical fantasies.

Falling around the Earth for crying out loud.  ::)

This centrifugal that is now not a force and is centripetal force that isn't a force unless it becomes a force when people start to question, yet manages to exert a force onto a so called space craft by is counteracted by another force that isn't actually a force unless questioned constantly, which then turns back into a sort of force that we simply just don't understand.

Imagine that?
Imagine trying to explain that from scratch to people who haven't been brainwashed.

A defiance of genuine physics. When you see a wall of death motorcycle stunt person going around and around, you don't wonder why he's not flying into the crowd outside   because you can see that his motorbike tyres are pushing against a barrier and that barrier is resisting that push.

Imagine that motorbike going super fast around a ball. What force could seriously pull it into the ball as opposed to stopping it shooting outwards in a straight line?

This centripetal force supposedly acts upon the ISS in space as if it's a swing ball machine and the ISS is the ball attached to the string as it's whizzing around the pole.
It doesn't fly off because of the string. The very same string that is bullshit gravity.
This invisible string force where the ISS just wants to piss off into space but good old gravity string says, "not on your Nelly Mr, you're on a leash."

Centripetal force and gravity allow the ISS to simply fall around Earth.  ::)

Ok all you scientific minded people. All those who possess the logic and common sense. I have an experiment you can do that will show you how much bullshit this is.

The tools you need are thus:

A lid from a jar that has a lip so it can hold a few small plastic beads.
A few small plastic beads.
A hand held battery operated face fan. A £ store or a $ store one.
A glue stick gun or some strong glue.

Oh and the main thing you need is a small vacuum chamber that will hold the fan and accessories.

Ok here's what you do.

You take the fan blade from the fan and pierce a tiny hole in the jar lid. You then push it firmly onto the fan shaft and glue the back and front so that the lid is stuck to the shaft.
You now glue the fan bottom to the bell jar vacuum base as close to the centre as you can and allow it to dry so it cannot fall over.
You put a few beads in the inside of the rim of the jar lid and switch it on.
You will find that your centripetal force is keeping the beads stuck to the rim, because it's basically like the motorbike wall of death, only this is vertical but same thing.

It's also how they tell you that the ISS is doing its  rounds in space.

Now here's the key.
Place your bell jar over the base with the working fan motor and jar lid plus beads spinning like crazy and start evacuating the pressure from that jar.

This is where you see your ISS fall from space to the bottom of the bell jar base, because centripetal force has now been rendered useless.
You see, the beads no longer adhere to the rim because it only works with atmospheric pressure and cannot and does not work without it.

Now all you genuine thinkers that want the truth, don't take my word for it, go and try it out for yourself.
If you have a chamber then the rest will cost you  £1 or a $1.

I'll see if anyone is willing to try this and if they are then it should clarify one hell of a lot to them.

Why would there be acceleration? If both are the same speed why do they depict people and everything else floating? They should not float until they go free falling towards the earth and I never see that happening unless they purposely want to.

If you go back to the very first page of this thread you will see that centrifugal and centripetal force was what got me started on the subject of orbit. scepti and legion are here to help back me up because they know that it takes a lot of common sense to wake people up and help them to realize that NASA is not your friend. NASA is lying about space travel and the truth need to be told. I just hope some people, that maybe on the fence about this stuff, find some understanding and realize they have been duped. I know I sure did. So, all and all I believe this thread has been worth it.

I just gave you an answer, both the iss and the astronauts have the same speed and acceleration, so there is no relative motion between an astronaut and the iss.

Why would there be acceleration? If both are the same speed why do they depict people and everything else floating? They should not float until they go free falling towards the earth and I never see that happening unless they purposely want to.
The confusion here seems to be "free fall". If by free fall you mean falling straight down to earth, then the astronauts are not in freefall, personally I think freefall is the wrong word for the situation.
Ill separate my argument into sections, tell me which one you don't agree with.
1. To be floating in the iss, an astronaut has to be not moving relative to the iss when he is not trying to move and is not touching any walls.
Freefall is one way of this happening but in this case it isn't
2. The acceleration is caused by gravity, and acceleration due to gravity is the same for all objects in a vacuum. So both the astronaut and the iss have the same acceleration and velocity.
3. Since the astronaut and iss have the same velocity and acceleration, they will follow the same path.
4. Since they follow the same path, there will be no relative movement between the iss and the astronaut.
Combine 1 and 4, and you have a floating astronaut.

I think 1 is the one you don't get.
If you think a person in a plane is also going at the same speed and acceleration, there is a difference.  A plane a person has to be touching the floor to not be falling, because the plane is generating lift to counter gravity, so a person has to be on the floor to be effected by the lift. On the iss this isn't the case, the iss is not producing any force, the only force effecting the system is gravity, which effects the astronaut where or not he is touching a wall.
Edit: reading what you have said I want to ask you something, what do you define floating as.

Videos show the folks and objects to be floating when they are not tied down or holding on.

2. The acceleration is caused by gravity, and acceleration due to gravity is the same for all objects in a vacuum. So both the astronaut and the iss have the same acceleration and velocity.

Okay

3. Since the astronaut and iss have the same velocity and acceleration, they will follow the same path.

Okay

Okay

Combine 1 and 4, and you have a floating astronaut.

Here is the problem I have. NASA says the astronauts are floating in space because of free fall and they even demonstrate this with the vomit comet. They say the ISS or any satellite simply falls around the earth. and because of that the objects are weightless and they float around. You have to be smart enough to know that any object coming under the influence of so called gravity is going to fall to earth unless it has a way to defy gravity. Even if the ISS or an airplane is flying, gravity will bring it down if it has no lift to keep it defying gravity. I don't see the ISS having wings.

To me, floating is when you are not under the influence of gravity or lighter than air.


I think 1 is the one you don't get.
If you think a person in a plane is also going at the same speed and acceleration, there is a difference.  A plane a person has to be touching the floor to not be falling, because the plane is generating lift to counter gravity, so a person has to be on the floor to be effected by the lift. On the iss this isn't the case, the iss is not producing any force, the only force effecting the system is gravity, which effects the astronaut where or not he is touching a wall.
Edit: reading what you have said I want to ask you something, what do you define floating as.

Videos show the folks and objects to be floating when they are not tied down or holding on. [/color]
Ok, that is because I was only looking at the force of gravity, the main force in the situation. If gravity was the only force there would be no relative motion, when you include the astronaut pushing off from surfaces and the force from the air inside the station hitting his body you will have him moving relative to the station. I defined floating badly; I'll give a better one.
Floating="When there is no permanent force pushing you against a surface.”
I hope this definition makes more sense, on earth we don’t float because we have a force pushing us down, so we can’t float up, and the friction from being pushed to the ground stops us from floating forwards, backwards, left and right. Same on a plane, the plane is staying at a constant height, and you are still going downwards because of gravity, so you are pushed against a surface again.

Now I think you have said you understand orbits, you just don’t consider them as free falling because they don’t go down. On the vomit comet you float because both you and the plane are being affected by gravity and nothing else, this causes you to not be pushed against any surface of the plane. Now in the ISS isn’t falling as in moving downwards, but it is accelerating downwards, so it’s not “free falling”, more “free accelerating”. It’s the “free accelerating” that causes things to float, since it means objects within it will not be pushed to one surface. If you think you would be pushed towards one surface of the ISIS, which one, down, up, backwards, and why.

And you have to be smart enough to factor in, and comprehend, the lateral velocity of the ISS and the astronauts traveling with it.

I hate to say it, but you have me a little confused here. It sounds like, again, you are saying gravity is not enough force to push them down. There is gravity, almost as much as on earth. Why would they float if they push off something?

I understand what they mean by orbit. I understand that forward motion is counteracting gravity and the object will travel around the earth. You say that the object is free accelerating towards the earth and that is causing things to float. What happened to the forward motion of the object trying to prevent that from happening. It would hit the atmosphere in only 38 seconds. If what you say is true, then they would have to constantly fire the rockets to overcome the gravity.

No, you obviously don't understand what they mean by orbit.  Forward motion does not counteract gravity.  Gravity is always pulling the ISS downwards.  The forward speed simply ensures that the ISS misses the earth.

I see the insults are coming out
Just because they are aimed at children; that doesn't make them true. Only a complete idiot would suggest that. And that you believe these videos knowing that they were "designed for children"!

How embarrassing. For YOU.
Yep. You're right. This was the very next post.

But legion is known for just tossing stuff like this in from time to time, so most of us are used to it by now and take it for what it's worth[nb]Approximately nothing.[/nb].

trust me, I understand what everyone is saying,
That doesn't seem so clear. Based on what you write here, you don't understand it at all.

Quote
I've read what  everyone has mentioned many times. I've tried to find the reason why object actually float on board the ISS and I can't. Mostly I find is that they are in free fall. I just want someone to explain why when they show the videos of the ISS everyone is floating and the women's hair is standing straight up and it looks unnatural as hell.
They are in free-fall and it isn't natural for people to be in that environment.

Quote
They are all floating around as if they are falling slower than the ISS is falling.
Why do you think this? If they were falling slower than the ISS is falling, they'd all be pinned to the ceiling[nb]The "ceiling" in this case is the part farthest from earth.[/nb]. But they're floating around, which is what you object to, which means they're not pinned to the ceiling.

Quote
I was under the understanding that objects in space fall at the same rate.
All objects in space don't necessarily "fall" at the same rate, they accelerate at the same rate[nb]If they are at the same distance from the center of the Earth, in this context.[/nb]. "Falling" at the same rate means they also have the same velocity, which isn't necessarily true in all cases. Objects in the same orbit do fall at the same rate at the same point in the orbit. Objects contained within another object in orbit do meet those conditions.

Quote
It is not obvious to me that that is true on the ISS because it looks like the spacecraft is actually falling faster than the objects inside and they never seem to catch up. I would expect to see them simply walking around normal.
Wait... if the spacecraft were always falling faster than the objects inside, unattached objects inside would be pushed against the side opposite the direction of fall. Are you seeing this? Obviously not, since you're complaining that the pictures show astronauts floating around inside it. So, how, exactly, does it "look" like this is happening? If that were happening, you would see them walking around normally, on the ceiling. Can you clarify what it is you're trying to say here because this makes no sense.

Quote
The gravity is only about 10% less, so it can't be that. I don't see the astronauts falling slower than the ISS when they are outside tethered to the craft. They seem to be falling at the same rate or the tether would be tight. It always seem to be loose.
The acceleration of gravity, regardless of what the exact value is, is the same for both because they are at the same distance from the Earth. In this case they are falling at the same rate, so there's no net velocity between them except when the astronaut outside accelerates to maneuver around. So what you see is exactly what would be expected. Why would you expect otherwise?

Quote
When I'm on an elevator and as it starts to go down I feel as if the floor drops out from underneath my feet, but as soon as my body catches up I don't feel it any longer.
The elevator accelerates downward from a stop for a few moments, then moves downward at a constant speed. You feel the floor drop as it accelerates, then your weight returns to normal when the acceleration stops and the downward velocity becomes constant.  This is high-school physics stuff. Consider you claim to have had a career in engineering, this is pretty disturbing since it's really, really basic and very well understood.

The relevant part of that linked post, near the middle of the last paragraph:
Quote
I'm a very technical person. I've spent nearly my whole life working as an electrical engineer. I've even designed products that were supposedly used on satellites.

Quote
I would just expect the ISS to be the same way. I don't want anyone to get mad and start chunking more insults towards me, but this is the way I see it and I simply don't understand.
Here are what I think are the possibilities. These aren't meant to be insults, just the possibilities based on what you say here:

1) You're willing to play the foil, pretending to be ignorant, and encouraging people to present facts in a very easy to understand way. Well done! <imagine thumbs-up emoji here>

2) You just enjoy posting stuff to see what response you can elicit. Still <thumbs up>, because it elicited a lot of easy to understand explanations for anyone casually reading.

3) You really don't understand how this works, and are "exaggerating" that career in engineering. <thumbs down>, but see comment after 2), above.

4) You really don't understand how this works, but somehow managed to have a career in engineering anyway. (Yikes!   :o )

5) You used to be a brilliant (or at least competent) engineer and used to understand how this works but don't any more.  :'( [nb]This happened to my mother-in-law; she was a very good engineer, and excellent at explaining engineering problems, until her last years; it was very sad and distressing to watch it happen.[/nb]

[Edit for completeness in third response.]

You need to understand  circular motion. Acceleration and velocity are different things, F=ma not F=mv, an object can be accelerating downwards and keep a parallel velocity, the velocity doesn't counteract acceleration, because it doesn't, they are different things.  People never feel velocity, only accelation. Of cause you feel the air when you have velocity relative to the ground but that is not the same thing.

Okay, let's get back to basics. Your article talks about centripetal force and centrifugal force not being a real force. Actually, centrifugal force is what we should be talking about. I'll give you an example of centrifugal force used in everyday life, a washing machine spinning out. That is how the water in the cloths are removed. Now give me an example of centripetal force used in everyday life.

Saying centrifugal force isn't real isn't correct, it appears in non inertial reference frame.
And centrapedal force happens when you tie something to a string and swing it around.
