Space Variation

[Nicholas]

Choose two objects lets say a train and the station.

There is a set distance between them until it accelerates.

If the train could approach(accelerate to near) the speed

of light it would measure a shorter journey.

I call this space variation.

 

But how can you say that the distance between the train

and the station in the begining isn't an absolute?

Every reference that stayed behind or was at the station

waiting would say the train had an absolute space to

travel through.

 

As Einstein said Relativity is a thoroughly bad name for

the theory. He considered calling it invariance theory!

[Tom Mattson]

But how can you say that the distance between the train

and the station in the begining isn't an absolute?

 

What do you mean by "an absolute"? Do you mean independent of reference frame?

 

If so' date=' then I can say that the distance is not an absolute because that statement is consistent with the best empirical data, and the negation of that statement is not.

 

Every reference that stayed behind or was at the station

waiting would say the train had an absolute space to

travel through.

 

This is so vague that I can't even guess at what you mean.

[Nicholas]

Space only varies with motion.

Speed up and space-time shrinks.

[Ophiolite]

From whose point of view?

[Nicholas]

From the point of view of who did the accelerating

ie who exerienceed weight.

They will see those left behind as being blueshifted and

when the measure space they will find it is shorter!

[Ophiolite]

Rubbish. You are being vague as usual. When they measure the length of their dining table it will be the same, n'est pas?

[Pseudoswallo]

I can see what your saying, Nicholas. Is this the 'observer based effects' part of the theory? Anyway, there are spinnies of trees, mysteriously placed every kilometer. Now, someone in a spinny sees the next, and mesures the distace correctly as 1km. On the train, however, they mesure it, again correctly, as 700m. Tada!

And is the dining table at the station or in the train?

 

ps.

Those in behind would be red-shifted, and those in front would bllue-shifted

i see the closing of the other threads and your warning haven't stopped your spamfest.

[J.C.MacSwell]

Space only varies with motion.

Speed up and space-time shrinks.

 

And expands

[Nicholas]

And expands

 

Do you make the difference between galaxies with space

expanding inbetween(space stretching) or galaxies moving

through space apart?

 

There is a difference.

In one only would there be relativistic effects.

I second this. Tom's answer is as clear as a bell in response to the first part of your question.

 

best,

I hope that no one is implying that nothing in this universe is absolute.Think about it if the universe is always changing than the only way to be absolute is to change our theories,laws, and principles to govern space-time effectivly. A great book that really stresses this is "Brian Greene" The Elegant Universe.

I don't mean to sound like I'm second guessing your intelligence,but maybe you should take a second look at Einstiens theory, because what it sounds like to me is that maybe you didn't fully understand the point he was trying to get across. Or a different approach, possibly you couldn't get your main point across in the process.Do you understand? If you don't you're being truthfull because I AM BEING VAGUE! Do you now understand why it is that you have to be undeceivably clear in the point you are getting across.

In light are you saying photon? What I mean is you have a caption saying light falls. In the scientific world at least is an understanding that photons have no mass and also they have no effect on the particle hence, photons never fall below 670 million mph in turn showing no effect from gravity.
