Absolute space....

[Gondolin]

This may be an easy answer to an easy question but I just don't get it.

I am reading Briane Greene's "Fabric of the Cosmos" and he talks about absolute space. Like the water conforms to the shape of the bucket because of absolute space. I don't understand that line for some reason. What exactly is absolute space.

[James R]

I don't understand it either. Maybe if you can give us a bit more of the context.

[MacM]

Maybe Brian Greene is crossing over to our side.

[Gondolin]

Well thats really all it says. The water expands because of absolute space. Thats about it.

No matter what Briane Greene's or anybody else of thoes super scientist, these are all theories, so dont worry much about thing that dont have concrete phisical proofs. Most of these theories are always controvertial and some are proved wrong by other such stupid theories.

So instead invest your time in learning some thing that is new and can be practically applied in real world.

MaC & Geist,

What were you doing during the past month?

MaC & Geist,

Pretty much what I am doing here with some necessary variation.

What were you doing?

Do you has "Fabric of the Cosmos" in electronic format?

>>because of absolute space.

Hum,
Perhaps he meant `because of its absolute space`

As in the shape of the bucket is affected by the motion through space time (the planet is moving), and that the shape is only a relative thing.

(i.e. if the bucket was moving very fast, then the space inside it would be less than if it were stationary)

Just a guess….

I did not understand your response over my comments

[MikeD22]

Gondolin,

In the Fabric of the Cosmos, when Mr. Greene discusses "absolute space" he is talking about the "aether" or an absolute reference frame.

I was "here here"ing to your comments, Anomolous.
I agree with what you had to say in the course of the thread.

It's the part about Newton's bucket, right? Remember that you're very early in the book, and that he's discussing historical ideas about the nature of space. Newton's bucket is introduced to illustrate the idea of absolute space: That there is a way to determine each point in space uniquely and that this frame (see James R's thread on frames) takes preference over other frames. The bucket, defining a reference frame in itself, can be seen to be spinning wrt. absolute space if the water curves, and not spinning wrt. absolute space if the water is flat, in Newton's thought experiment.

When you get to the part in the book that descrbes relative motion be prepared to make a decision.

If you run by me at 2 meters per second with respect to the ground and I am running at 1 meter/second with respect to the ground our relative velocity is 2 - 1 = 1. This is what relative velocity is. If a light is moving past you with the speed of 1c unit of light with respect to the ground and you are moving at 1/2 the unit of light c with respect to the ground then the relative velocity of the light with respect to you is like the race we had, 1c - 1/2 c = 1/2c, the measured relative velocity of frame, that's you, and photon.

Don't let anyone try to fool you into believing otherwise, or your mind will open so wide your brains will fall out, yes indeed, all half dozen or so of your total brain cell count will spill out.

If a light is moving past you with the speed of 1c unit of light with respect to the ground...

Serious flaw here - light does not move with respect to the ground.

[James R]

geistkiesel:

Unfortunately, your velocity addition idea has been disproven by innumerable experiments.

You are a brave girl.

Then what does it moves with respect to ?

[(Q)]

It moves with respect to the medium it travels.
