TheRealBillNye should have a disclaimer in his signature saying that he is not the real Bill Nye. Otherwise when people find out that he isn't real, the misleading propaganda he hocks will look even worse. Rabinoz, please do explain these gravitational forces that vary over the dimensions of the object which we call tides or what not. I would love to get pernickity about it, seeing as that's all you seem to do here.

Weightlessness = not being affected by the downward-pulling force/acceleration that is usually exerted on us, i.e. keeps us on the ground.

By this definition, weightlessness is impossible. Even when the astronots went to the moon, they were still under the effect of earth "downward pulling force". Don't you see why sceptimatic gets fed up? I am as well.

That definition of weightlessness isn't technically correct, it is more like not having a normal force acting upon you.
Since all mass has its own gravitational field, technically the best you can do is what's called a microgravity environment.

However, this microgravity (like a vacuum chamber) is generally so small that it can be safely ignored for all but the most sensitive observations.  That's why it's commonly referred to as weightlessness or zero gravity.

Quote from: Triangles on December 14, 2016, 04:55:00 PM
The reason that isn't correct is because while falling, you are weightless but still under gravitational acceleration.

That depends on whether you're referring to proper acceleration or coordinate acceleration. 
Quote from: https://en.wikipedia.org/wiki/Proper_acceleration
In relativity theory, proper acceleration is the physical acceleration (i.e., measurable acceleration as by an accelerometer) experienced by an object. It is thus acceleration relative to a free-fall, or inertial, observer who is momentarily at rest relative to the object being measured. Gravitation therefore does not cause proper acceleration, since gravity acts upon the inertial observer that any proper acceleration must depart from (accelerate from). A corollary is that all inertial observers always have a proper acceleration of zero.

Come on mannnnn, I'm tryna explain it simply

I'm happy to leave it simple if you will, but when I said a spacecraft is in a "zero g" situation, that is strictly true for only one point in it.

It's too big a topic to do in a simple post, but Fg = (G x m1 x m2)/d2 so Fg varies slightly over the dimensions of the object.

In the case of a spacecraft, even the ISS, this is quite negligible, but the earth is large enough for the sun and moon's gravitational field to be different on the near and far sides.
It's a long story from there to the explanation on tides, but it's the start.

If you are interested, which is unlikely since it involves that terrible gravitation, you could start with Hyperphysics, Tides.

Scepti, let me see if I understand what you're saying here.  There is a dome covering a flat earth, and sealed inside that dome, among other things, is our air.  It is the pressure from this air that is holding us to the ground.
I know that's probably a little simplified but does that about sum it up?
Perfectly well.

But why does the plane fall?  Why does anything fall?  Why should air pressure be greater at the bottom of a mass of air unless something is pushing the air down? 

Sceptimatic, all of your arguments seem to compose a more or less correct accounting of what air pressure is, but all explanations of why things tend to fall down instead of any other direction seem to boil down to "things just fall down because they do".

Air pressure, even as you describe it, doesn't work without gravity.  You can take the "down-fallingness" of objects as axiomatic if you like, or call it anything other than gravity.  But that phenomenon exists independent of air pressure and plays a fundamental role in making air pressure work how it does.
So you're saying that air pressure doesn't work unless there is the use of something you know nothing about or even if it exists?
I know you're going to say that you know lots about it.
Ok, fair enough. Explain what gravity IS.

The people inside the plane and the plane itself are both falling at the same rate. I mean, they were both flying (moving) at the same rate before the parabola, correct? And at that altitude, the plane is pressurized to a much higher psi than the air pressure outside the plane, correct? In fact, wouldn't you say the air pressure inside the airplane would be the same as the air pressure inside the submarine we discussed? Yet they float in the plane. The pressurized plane.
All you are doing is sky diving in a sealed unit (plane).
Oh and a submarine isn't dropping like a stone for anyone to appear to float.
The people in the sub and the people on the plane in normal flight are still held down. You claim it's the pressure that keeps them down, inside a sealed unit. So if you're sitting in your seat on the plane, you claim pressure is holding you down. But when the plane enters its parabola, you float up out of your seat inside the pressurized plane. What force is now taking over? Why are you not held to your seat by the very pressure that was holding you before? No, you're not skydiving, you haven't left the pressurized plane. So what if you're falling, what are you falling from? What is this new external force overcoming pressure?
Pressure is overcoming pressure.

Ummm....  That isn't what I said.  No matter how you stack it, air pressure has no preferred direction of action like gravity does.
Atmospheric pressure acts upon everything and anything in any form and any way.
Gravity is still a made up fictional force (not a force?) no matter how you dress it up.


Quote from: markjo on December 14, 2016, 11:52:07 AM
There are several very complicated explanations for gravity (General Relativity, Quantum Gravity, etc.).  Just because you can't understand them doesn't mean that they aren't there.
What is general relativity in your best simplest kiddified terms?
Also quantum gravity.
Don't copy and paste a load of complicated nonsense. Just give me the basic nutshell.

Quote from: markjo on December 14, 2016, 11:52:07 AM
Atmospheric pressure is very real, it just doesn't do everything that you think it does.
It does everything.
We are alive and moving with everything in its place because of it.


Quote from: markjo on December 14, 2016, 11:52:07 AM
  The simple fact of the matter is that the weight of objects don't change when atmospheric pressure changes.
The simple fact is that weight of objects do change when atmospheric pressure changes.
Just remember that weight is nothing more than a man made scale of measurement of any dense matter.

Quote from: markjo on December 14, 2016, 11:52:07 AM
  No amount of atmospheric stacking can change that reality.
But atmospheric stacking does change things. It changes the entire make up of Earth all through the man made/thought years.

I'll reiterate a point someone made earlier. The moon has next to no atmosphere, so how can it have denspressure?
It doesn't exist as a physical body in the sky to have denpressure.
It's a reflection.

Pressure is overcoming pressure.
You always have another meaningless statement to explain away every new situation.

By the way, I know how you just love equations, so:
Electrostatic force:
    Fe = -(k x Q1 x Q2)/d2
Gravitational force:
    Fg =  (G x m1 x m2)/d2
They look pretty similar, why accept one and not the other?
You cannot possibly deny the existence of electrostatic attraction, so now, you explain exactly what electrostatic attraction IS!

Yes, you can easily demonstrate electrostatic attraction but you cannot easily demonstrate gravitational attraction.

The only reason for this is that gravitational forces for practical objects is far lower than electrostatic forces.

But, it could not be any other way. For gravitation to be easily demonstrable it would need to be at least a million time stronger.
 ::) Just how would you feel if you weighed 1,000,000 x 80 kg?  ::)

Just because gravitation cannot be easily tested on your kitchen table is absolutely no argument against it.

I know, he should of just added the disclaimer instead of posting a hollow  response and looking foolish. Why is it that the counterarguments against Denspressure always end up being...youre on physcotropic drugs... Or something of that nature. Why did you ignore spectimatics last post as well? Where's your simplified definition of relativity. I wanna know! Your definition of weightlessness was illuminating to say the least lol

The Cavendish Experiment was the first experiment to accurately measure the value of the gravitational constant.

Henry Cavendish, in 1787, constructed a balance with four lead balls: two big and two small. The two big balls were suspended on a wire while the two small ones were placed into the frame.

When the system was let go, the two suspended balls twisted slightly as they were attracted to the other lead balls. He used the torsional force in the wire to calculate the value of G, the gravitational constant. He came within 1% of the currently accepted value too, impressive right?

It was performed horizontally to limit the effects of Earth's gravity.

Basically that is what it is, you can read about it more here: Cavendish Experiment

Its amazing how all these experiments that are centuries old always come so close to the "currently" accepted value... Al biruni... Eratosthenes... Cavendish... Its almost as if THEY created the "currently" accepted values lol. Anyhoo, care to explain the big bang? The currently accepted version of course...

Right, but I'm only interested in the pressure side of it for now.
Air pressure outside the plane is lower than air pressure inside because it's at a higher altitude, where the air is thinner. It's measured in pounds per square inch, or psi. Think of it like an air compressor with a tank. Most everyone either has one, or knows how they work at least. The air is pumped inside the sealed tank, compressing it, and holding it with valves. So the pressure is greater inside the tank than outside. Same as the plane at altitude, same mechanics in fact. The only way to change the pressure inside the tank (or plane) is to either add more air or release it. That pressure doesn't change. Right? Right. OK, so back to the plane at altitude. No air is added or released, it stays the same. And you say that is what holds you to your seat. During parabola, you float out of your seat, mind you the air pressure hasn't changed. And you say -
As I mentioned above. The pressure does change. It only stays constant when the plane is moving at a constant speed.
But I'm telling you that the pressure CANNOT change unless MORE AIR is pumped into the cabin (think back to the air compressor/tank) (you could decrease the size of the cabin, effectively increasing the pressure, but for the sake of argument we're not using this option, alternatively you can heat the air as well for +psi). You want higher air pressure, you must add more air. That's just fact. There are gauges that measure psi. During parabola, lift off, or descent, you would see the needle move drastically if it were enough to raise you from your seat, or push you back into your seat during take off. And we know doesn't happen.
Now I suppose it's your turn to tell me how pressure changes inside a sealed vessel without the aforementioned ways - heating, volume compression, and addition of more air.

I'll reiterate a point someone made earlier. The moon has next to no atmosphere, so how can it have denspressure?
It doesn't exist as a physical body in the sky to have denpressure.
It's a reflection.

A reflection of what, Scepti? Where does the light come from?

What did Cavendish measure?
I don't know. What did Cavendish measure?
The attraction of one object to another proportional to their mass.  Since you don't believe in that, what do you think he, and the many people that have repeated and/or improved on his experiment since, measured.
How did he manage to do this and what did it physically verify?
In your own words, simply and clearly if you can.
The Cavendish Experiment was the first experiment to accurately measure the value of the gravitational constant.

Henry Cavendish, in 1787, constructed a balance with four lead balls: two big and two small. The two big balls were suspended on a wire while the two small ones were placed into the frame.

When the system was let go, the two suspended balls twisted slightly as they were attracted to the other lead balls. He used the torsional force in the wire to calculate the value of G, the gravitational constant. He came within 1% of the currently accepted value too, impressive right?

It was performed horizontally to limit the effects of Earth's gravity.

Basically that is what it is, you can read about it more here: Cavendish Experiment
What the hell is that supposed to mean?

The Cavendish experiment was designed to test gravitational energy present in everyday objects. Since he did not want the gravitational pull of Earth to effect his experiment, he suspended the 2 lead balls midair at the exact same height. The energy transferred between the 2 balls caused them to rotate. The force of this rotation was calculated, and the constant g was born.

Scepti, let me see if I understand what you're saying here.  There is a dome covering a flat earth, and sealed inside that dome, among other things, is our air.  It is the pressure from this air that is holding us to the ground.
I know that's probably a little simplified but does that about sum it up?
Perfectly well.
Ok so we are in a pressurized dome.  Why is the air pressure lower the higher up you go?  Shouldn't it be equalized throughout?

No it isnt. Scepti claims gas particles can stack like a pile of sand. What scepti doesn't  realize is gas particles do not behave in the same way as solid particles.

I suggest you read up on the most basic properties of gases and then get back to me.

I'm sorry but if it's there I'm missing it.  I don't see how the atmospheric pressure would not be evened out inside a pressurized dome, unless something was specifically pushing it downward.  Like gravity.  Without that it would be even everywhere.
