So, I have an assumption that the sun is a giant table lamp. If the sun is a giant lamp then we should see light eminating from it. We do see light eminating from it. The giant lamp hypothesis is therefore supported, since it makes testable predictions that work.
Correct. That one particular test is passed. Of course, we can make another prediction that doesn't get passed, and thus the hypothesis is disproven. I leave it as an exercise for the reader to devise such a prediction.

Does that mean science proves the sun is a giant lamp?
No, and I have been quite careful to never use the word 'prove': science doesn't prove anything, no matter how many falsification tests a given hypothesis passes. As I keep saying, the heliocentrism hypothesis makes testable predictions which it continuously passes: this constitutes evidence. Not proof, since, as you so aptly demonstrated above, false hypotheses can still make correct predictions.

Oh I thought this was 'ask a physicist anything' and he'll come up with the answers. Never mind.
...
I thought you were dishin' out answers? No your telling me to go find out for myself.
Answers, yes. Doesn't mean I'll trawl the internet at your leisure.

I've never seen any parallax or aberration. If you want to show me some maybe I can explain it.
Really? You deny that stellar abberation is a real phenomenon?

The rest use stellar phenomena to calculate star distances that you mentioned.
Indeed. And they do so without using heliocentricity, which means they're the same in a geocentric model as well.

Any trigonometry that makes up a 186 million mile baseline is false. And thats FACT.
The evidence begs to differ.

No I don't. How far is Pluto way from Earth?
Aphelion: 7,375,927,931 km
Perihelion: 4,436,824,613 km

The coreolis force is created by the entire universe rotating around the fixed Earth.
And how does the universe's rotation affect the movement of Foucault pendula? What force is imparted by the most distant stars onto the pendulum's mass, exactly? If the universe is spinning around the Earth, why do Foucault pendula exhibit rotational periods depend on their latitude? How does this explain why stellar parallax operates on a 6-month period?

Moreover, how do you get around the problem of superluminal stars?

I really don't know what your talking about.
If I throw an object while standing on the Earth, the Earth itself gets pushed. Newton's Third Law: For every action, there is an equal and opposite reaction. If I throw an object forward, I must therefore be thrown back with equal and opposite force.
Thus, I can make the Earth begin to rotate: all I need to do is apply a torque to it. A single meteorite colliding with the Earth will do nicely. Given that several tonnes of material lands on Earth every year, we have substantial torque imparted to the Earth.

In essence, even if the Earth was created stationary, it's spinning nowadays by virtue of material being deposited on it and imparting small, but finite, motion.

You have a theoretical reason.
Methinks you don't understand why 'theoretical' isn't a naughty word. Perhaps you think evolution is 'just a theory'?

I tried dropping an apple. Surprisingly it didn't orbit my ankles.
Indeed: it obeyed GR and fell to the ground. We can use GR to create orbits, however, which is why there are several thousand satellites orbiting the Earth as we speak.

Of course it was a hoax.
:doh:

Gravity is heavyness. I believe in that force.
Gravity is 'heavyness'... care to elaborate? Do you deny that two objects of mass are attracted to each other proportional to the product of their masses?

In the geocentric system, what you see is what you get, You can believe you're own eyes. The pendulum is really changing it's direction and the falling object is really moving sideways. It's reality. It's nice.
The most intuitive explanation is rarely the correct one. Careful analysis of the evidence almost always reveals something more complex going on - which is why we've discarded Classical Mechanics.

In any event, we don't deny that the pendulum appears to spin. We simply attribute its spin to a testable phenomenon

I've seen an explanation from geocentrists but I'll wait until I've seen the actual phenomenon till I bring it forward. Not that I understand the math involved but you might. :thumbsup:

Barbour and Bertotti tested rotating a hollow shell around a solid central sphere and found that coreolis and centrefugal forces were created.
They were quite mistaken: A shell of matter around an object imparts no gravitational force onto that object. This is part of the shell theorem, and was proven by Newton some time ago.

If the hollow sphere is the universe and the solid central sphere is the Earth then that would explain the phenomenon in a geocentric universe.

This is from the book "Galileo was Wrong" by Dr. Robert Sungenis and Dr. Robert Bennett. 650 pgs.

Quote:

One can imagine why many who were looking for proof of a rotating Earth would appeal to the Foucault pendulum. It seems logical to posit that the reason the plane of the pendulum appears to be moving in a circle is that the Earth beneath it is rotating. In other words, the heliocentrist insists that the pendulum's circular motion is an illusion. The pendulum is actually moving back-and-forth in the same plane and the Earth is turning beneath it. Since the Earth is too big for us to sense its rotation, we instead observe the plane of the pendulum rotate. All one need do to prove the Earth is rotating, he insists, is to reverse the roles, that is, imagine the plane of the pendulum is stationary and the Earth beneath it is moving. This particular logic, however, doesn't prove that the Earth is rotating. One can begin the critique by asking this simple question: if the pendulum is constantly swinging in the same plane (while the Earth is rotating beneath it), what force is holding the pendulum in that stationary position? In other words, if the plane of the pendulum is stationary, with respect to what is it stationary?
It's stationary as in there is no force moving it.

This is understood as an 'unresolved' force in physics. The only possible answer is: it is stationary with respect to the rest of the universe, since it is certainly not stationary with respect to the Earth. With a little insight one can see that this brings us right back to the problem that Einstein and the rest of modern physics faced with the advent of Relativity theory: is it the Earth that is rotating under fixed stars, or do the stars revolve around a fixed Earth? As Einstein said: 'The two sentences: the sun is at rest and the Earth moves, or the sun moves and the Earth is at rest, would simply mean two different conventions concerning two different coordinate systems.'
Einstein was referring to the arbitrary way in which we can pick inertial frames. However, the Earth is not an inertial frame: it accelerates. The logical position to pick is that of the barycentre - which is near the centre of the Sun.

As such, it would be just as logical, not to mention scientifically consistent, to posit that the combined forces of the universe which rotate around the Earth are causing the plane of the pendulum to rotate around an immobile Earth. In other words, in the geocentric model the movement of the pendulum is not an illusion, it really moves.
Bald assertion. There is nothing that suggests the universe itself is causing the pendulum to move.

According to Einstein, there is no difference between the two models.
The good doctors are quite mistaken, Strangelove.

Ernst Mach, from whom Einstein developed many of his insights, stated much the same. He writes: 'Obviously, it doesn't matter if we think of the Earth as turning round on its axis, or at rest while the fixed stars revolve round it. Geometrically these are exactly the same case of a relative rotation of the Earth and the fixed stars with respect to one another. But if we think of the Earth at rest and the fixed stars revolving round it, there is no flattening of the Earth, no Foucault's experiment, and so on..'.
Correct. We can model physics using non-inertial references frames, such as a non-rotating Earth. But that gives rise to fictitious forces, like the Coreolis force. The point is that we want to pick an inertial reference frame, which the Earth is not.

Barbour and Bertotti proved that a large hollow sphere (representing the distant star fields) rotating around a small solid sphere inside (modeling the Earth) produced exactly the same pattern of Coriolis and centrifugal forces that are claimed as proof of Earth's spinning in space. If the hollow shell of matter accelerates or rotates, any object inside the shell will tend to be carried along with the acceleration or rotation to some extent.
I'm sceptical of this claim, since Newton disproved such a notion a long time ago.

But they note this all-important fact: An object at the center of the hollow sphere will not be affected by the inertial forces. The space around the Earth will exhibit the inertial effects of the distant sphere, but not the Earth itself, if it is centrally located.

From Mach's principle we can conclude that inertia is a universal property, like gravity. But in Mach's principle the conventional interpretation of distant masses as causing inertial effects around the Earth is too restrictive. The cause of inertia could also logically be the properties of the space around each object, modified by the presence of the mass in or around that space. In other words the ether/firmament may be the source of inertia, which causes the gravity and inertial effects on bodies embedded in the ether. The ether's properties are changed by the masses (via feedback), but it is the ether that is the primary or first cause. Linear inertia is the resistance to motion of objects moving linearly caused by the ether drag.
Since both the aether and the firmament have been soundly refuted, all we have left is a gross misapplication of Mach's principle:

"You are standing in a field looking at the stars. Your arms are resting freely at your side, and you see that the distant stars are not moving. Now start spinning. The stars are whirling around you and your arms are pulled away from your body. Why should your arms be pulled away when the stars are whirling? Why should they be dangling freely when the stars don't move?"

The reason, of course, is that there isn't a real force between the stars and your hands - the force comes from your body spinning. What these people seem to have done, however, is committed the cardinal sin of statistics: they assumed that correlation implied causation. Your hands fly out when the stars spin, therefore, the spinning stars pull at your hands. Obviously this is nonsense.

I've heard that Focault Pendulums are faked too. Have you examined the ones you've seen to make sure there are no mechanical parts or rigged areas?
Yes. The one I mentioned earlier was set in the main stairwell, so you could easily look at any point along the wire. It was not rigged.

Do you have any evidence that any Foucault Pendulum is faked? The simplicity of the experiment is such that there is one in pretty much every major establishment of science; Wikipedia has a nice list. Are you suggesting that there is a massive conspiracy?

That's pretty much the explanation du jour for the "alternative science" crowd.

For the love of...

I gather you don't believe them :p ... but for the record, the experiments performed at the LHC involve particles colliding.
These collisions have very high energy densities, the highest on record for a scientific experiment.
These densities are said to cause micro black holes to form (and cause sinkholes...).
These same densities occur in the upper atmosphere.
We don't get black holes in the atmosphere.

In other words, the LHC is safe because it's not doing anything that doesn't occur already.

Please, ladies, calm down! Let WC guide you safely to his underground anti-micro-black-hole bunker :cool:

Look at the orbital path of Mars which is the red dot. It never passes between Earth and the Sun.

Indeed, if you consider the universe from the reference frame of an observer on Earth, then the rest of the universe rotates around you.

The problem with adopting this as support for geocentricity is that it is valid for any other point in the universe.

Coriolis forces on Venus can be explained by saying that the universe rotates around Venus.

So does that mean the Earth moves?

Ok so the end result of this stellar parallax stuff is that it's certainly not proof that the Earth moves and offers only theoretical evidence that it does. Of course man can theorise absolutely anything he wants, so really it's not evidence at all.

Answers, yes. Doesn't mean I'll trawl the internet at your leisure.


Really? You deny that stellar abberation is a real phenomenon?

No I've just never seen it.

Indeed. And they do so without using heliocentricity, which means they're the same in a geocentric model as well.

Exactly so they're not evidence that the Earth moves either.

The evidence begs to differ.

Whatever evidence you have is built on a massively faulty foundational baseline. And theres no way round that.

Aphelion: 7,375,927,931 km
Perihelion: 4,436,824,613 km

If thats based on heliocentric parallax then I'm confident that those figures are approx. 23,250 times larger than they should be.

And how does the universe's rotation affect the movement of Foucault pendula? What force is imparted by the most distant stars onto the pendulum's mass, exactly? If the universe is spinning around the Earth, why do Foucault pendula exhibit rotational periods depend on their latitude? How does this explain why stellar parallax operates on a 6-month period?

The force has been tested under labaratory conditions. It's real. The universe rotates at it's fixed celestial pole. The north star. So obviously the force varies depending on you're latitude on Earth.

Moreover, how do you get around the problem of superluminal stars?

How do they disprove a stationary Earth. Do they involve a) Theoretical stellar parallax or b) some other kind of theory?


If I throw an object while standing on the Earth, the Earth itself gets pushed. Newton's Third Law: For every action, there is an equal and opposite reaction. If I throw an object forward, I must therefore be thrown back with equal and opposite force.
Thus, I can make the Earth begin to rotate: all I need to do is apply a torque to it. A single meteorite colliding with the Earth will do nicely. Given that several tonnes of material lands on Earth every year, we have substantial torque imparted to the Earth.

You're saying we move the Earth when we dig up a peice of it???


In essence, even if the Earth was created stationary, it's spinning nowadays by virtue of material being deposited on it and imparting small, but finite, motion.

But you have no real evidence of the movement.

Indeed: it obeyed GR and fell to the ground. We can use GR to create orbits, however, which is why there are several thousand satellites orbiting the Earth as we speak.

We don't use GR to create orbits. We throw an object out there and a force holds it in position and allows it to orbit the Earth. We also can send a satellite into a high Earth orbit and keep it there absolutely stationary relative to a stationary Earth. Gravity or Electromagnetism?


Moon landing hoax >>> :doh:

Oh ya.....coz our government would neeeeeeeever lie to us would they?

Question for a physicist : Do you believe that the World Trade Centre twin towers AND WTC 7 collapsed due to fire, when no such phenomenon as ever been observed before regarding steel framed structures before OR since 9-11 without the use of strategically placed controlled demolition charges?

Gravity is 'heavyness'... care to elaborate?

Elaborate? Nope. Thats what it means, heavyness. Thats all it means.

Do you deny that two objects of mass are attracted to each other proportional to the product of their masses?

Uhm.....what force or theory are you reffering to here? Is it theoretical?

The most intuitive explanation is rarely the correct one. Careful analysis of the evidence almost always reveals something more complex going on - which is why we've discarded Classical Mechanics.

Careful theorizing of evidence reveals more complex things going on.

In any event, we don't deny that the pendulum appears to spin. We simply attribute its spin to a testable phenomenon

No you attribute it's spin to a theory.

They were quite mistaken: A shell of matter around an object imparts no gravitational force onto that object. This is part of the shell theorem, and was proven by Newton some time ago.

Is a centrifugal, coreolis force the same as a gravitational force?

It's stationary as in there is no force moving it.

Stationary with respect to what?

Einstein was referring to the arbitrary way in which we can pick inertial frames. However, the Earth is not an inertial frame: it accelerates. The logical position to pick is that of the barycentre - which is near the centre of the Sun.

You stating that Earth accelerates does NOT make it so.

Bald assertion. There is nothing that suggests the universe itself is causing the pendulum to move.

The good doctors are quite mistaken, Strangelove.

Did you want to debate their experiment or do you just wanna say their wrong?

Correct. We can model physics using non-inertial references frames, such as a non-rotating Earth. But that gives rise to fictitious forces, like the Coreolis force. The point is that we want to pick an inertial reference frame, which the Earth is not.

Again, you saying the Earth isn't stationary doesn't make that a fact. It's just you saying it.

I'm sceptical of this claim, since Newton disproved such a notion a long time ago.

Using theoretics per chance? The B&B experiment stands.

Since both the aether and the firmament have been soundly refuted, all we have left is a gross misapplication of Mach's principle:

Hold on a sec. The 'aether' was a VERY generalized 19th century name for the 'stuff' that space is made up of. Is it you're position that space is made up of nothing rather than something? Is it a perfect vacuum?

Yes. The one I mentioned earlier was set in the main stairwell, so you could easily look at any point along the wire. It was not rigged.

Do you have any evidence that any Foucault Pendulum is faked? The simplicity of the experiment is such that there is one in pretty much every major establishment of science; Wikipedia has a nice list. Are you suggesting that there is a massive conspiracy?

Ask the person who maintains the pendulum it they 'turn it off' at night and see what he says. Ask him if theres any rotationary 'teeth' mounted at the very top of the wire, possibly hidden in the ceiling mount.

This is pretty moot as the B&B experiment covers coreolis force in the geocentric universe...........but interesting to discuss none the less.

So does that mean the Earth moves?
Yeah, it does. While it's easy to say that you can look at it from two points of view: either the Earth is spinning or everything else is spinning round the Earth, it's also just as easy to apply that to any other apparently rotating body.
Problem is that stuff like the Coriolis effect only make sense if we consider them on a spinning Earth.

Imagine you're standing in a blacked out van and suddenly you're thrown against the back doors.

Does it make more sense that some unknown force is pushing you to the back of the van, or that the van is accelerating away?

There's been a lot of posts, and I can't find mine, but has the fact that if the Earth is indeed at the centre of the universe, the stars are moving faster than the speed of light been dealt with yet?

Yes. Because the method that scientists use to measure star distances, and thus speeds, are bulit on the faulty premise that the Earth orbits the sun. That assumption is actually part of the trigonometry that triangulates the star distance. It's the baseline measurement. 186 million miles. If the Earth is stationary (which real observation suggests) then that baseline can be no more than 8,000 miles. Which means the measurements are off by a ratio of 23,250 to 1. In fact a baseline of 8,000 miles doesn't even allow us to triangulate anything outside of our own 'Earth system'.

So basically, we dont know how far away stars are...and we dont know how fast they are moving.

Don't you worry, that magazine makes me really stressed reading it. The amount of pure bull that it contains is purely amazing.

Once I read that someone had written in saying that they had come up with the SM all by themselves and had sent all the details to loads of scientists and never heard back from them. He was happy to have that magazine publish his "work" finally and called for scientists to give him several noble prizes and loads of money.
