How do you guys explain the Foucault's Pendulum which provfs the earth rotation?

Conspiracy.
Like the sun, the stars are also expanding and contracting their diameter as they spin around the hub every six months.

Tom says there's secret motors that cause the apparent shifting.
So what about the ones you can set up under a ladder?

Unpowered pendulums are influenced not by the rotation of the earth, but by the gravitation of the rotating heavens, which rotate overhead at one rotation per 24 hours.

The large pendulums you would find in a museum running 24/7 are driven by electromagnets and are really just props. Real pendulums need to be reset every couple hours due to air friction.

Rotational gravitation has never been experimentally confirmed. It is pure speculation.

For someone who always demands hard data, you are very reluctant to give it. Can you cut the hypocrisy, please?

Sure they're powered by electromagnets, but I don't see why those would impart a rotation onto the pendulum.

Watch the pendulum as it swings. It will rotate in the direction of the stars overhead.

That's a direct cause and effect.

Ah! The good old "correlation implies causality" fallacy. Still no experimental data then?

I'm thinking, one large rotating mass causes another (light) mass to begin to rotate, with control setups and error analysis. That sort of thing. Some proper science.

Why would I need to provide experimental data for what one can already see for himself?

How about some experimental data for what no one experiences? Where's your evidence that the earth is moving in the Foucault Pendulum experiment? Anyone can watch and see that it's the pendulum that's moving while the earth remains still. Where's your evidence that the pendulum is still and its the earth which is moving?

The burden is on you to prove the unobservable. I don't need to prove the observable. Everyone can already see that it's the pendulum which is moving.

Simply by looking, one can't tell either way. Thus, experimental data is needed.

If you're theory was correct, anything that was suspended would be subject to this "rotational gravitational pull". Anyone can see that this doesn't happen (chandeliers, for example, don't slowly rotate). What we observe matches predictions made by RET, but not FET.

Chandeliers aren't in motion or free fall. Nor are chandeliers massive enough to be affected. If you've ever seen the weight of a Foucault Pendulum you would see that it's very massive and needs to be swinging in free fall for it to rotate.

How can they see that? They see relative motion of the chandelier and the Earth. How can they tell which one is moving?

Why does an object need to be in swinging to be affected? Why does it's mass matter?

Also, you wrongly state that a pendulum is in free fall. It is not, it is tethered.

Ask anyone to watch a focault pendulum for a while and they'll tell you that it's the pendulum which moves not the earth.

If you're trying to tell us that the pendulum is still and the earth is actually moving, the burden of proof is on you to prove your unobserved and unexperienced assertion.

So where's your proof?

Quote

Attach a spoon to a fishing line and put it into a swing. It won't rotate. The weight needs to be massive and it needs to be swinging in order to get the right effect.

The weight needs to be swinging in free fall because the force is very very slight, and its easier to move something in free fall than it is when its suspended motionless at 1g.

The weight also needs to be massive because of air friction. Massive bodies move with greater momentum through air friction. Small bodies like a spoon would quickly flutter out of control and slow to a halt.

Quote

When the pendulum is swinging back and fourth it's constantly going into freefall as it comes back down.

Non-swinging objects do not rotate. Therefore, the swinging causes rotation, not some "rotational gravitation". Also, the Earth seems to bulge at the equator, implying it rotates.

Now, could you please supply some evidence that the pendulum is rotating, not the Earth? "It looks that way" is not an answer.

I think it would rotate, however it would quickly slow down due to air-reistance. This is why the mass needs to be large.

The weight needs to be swinging in free fall because the force is very very slight, and its easier to move something in free fall than it is when its suspended motionless at 1g.

As I've said, it is not in free fall.

Quote

When the pendulum is swinging back and fourth it's constantly going into freefall as it comes back down.

"Free fall" means that the body is moving only under the influence of gravity (or, in FET, has no forces acting on it whatsoever). A pendulum is always attached to a tether, and so is moving under the influence of gravity and tension in the string (or, in FET, under the influence of tension on the string). Thus, it is not in free fall.

So, we either have a rotating planet and stationary pendulum , or a stationary planet and rotating pendulem. We have no kind of evidence for suggesting one over the other.

Now, the former requires nothing extra. It's simply an expected side effect of the model. The latter requires an extra force which is undetectable otherwise to be included. Which is the simpler model?

The heavens are completely unexplainable in FET. For example, how the same stars are seen at opposite ends of the southern hemisphere, and how star-light can be seen down to the horizon through the 'thick atmosphere', but not an ounce of the sun's diffuse light can be seen.

Since observation takes priority for you, this guy must be right, which means that your sun diameter calculations (and all theories based on it) are wrong, unless you can prove otherwise: http://theflatearthsociety.org/forum/index.php?PHPSESSID=b0486452a47573500fb7081378f3d07b&topic=19790.0

That's why you don't use a spoon, like an idiot: http://www.galeschools.com/sci_try/foucault.htm

It's easy to detect the gravitation of the heavens. Just set up a Focault Pendulum or take a g-meter to extreme altitudes.

If we look at star trails we'd see that stars actually do fade out into the atmosphere before hitting the horizon.

You are assuming that a Foucalt pendulum is moving and the Earth is stationary. You are assuming that the stars exhibit gravity but not the Earth. Why not show some proper evidence, not based on assumptions.

Like, for example, the Cavendish experiment. Or noticing that the Earth appears to bulge at the equator.

This is such a fundamental claim that no scientist would ever bother writing a statement saying it was true. This is because if it wasn't, astronomers would notice. Very. Quickly.

That would be, as you claim, due to the thickness of the atmosphere. However, your theory does not explain why those stars can shine through the atmosphere clearly, but not an ounce of the sun's diffuse light is visible.

Why does it make a difference if it's a star, planet, or other celestial body? The point is, these (relatively dim) objects can be seen through atmospheric haze, but the sun cannot.
