Re: Velocity of hyperspace

Well, here is something to think about:

Since time in general progresses slower the closer you get to the speed of light, imagine you sitting in a space ship that is flying at 0.99c.
Now, you travel quite a distance. For an outside observer (not moving relative to you), you will take i.e. 100 seconds for the distance. However, since time is slower in your space ship, it will only take 1 second from your viewpoint.
As a consequence, the perceived speed you think you are travelling at will be a lot higher than 0.99c, because from your viewpoint, you havent travelled the certain distance in 100 seconds, but in 1 second.

Therefore, in theory, reaching a _subjective_ speed that is greater than the speed of light should be perfectly doable. Also, the perceived speed would go to infinite as you approach the speed of light.

I was given to understand that any particle with mass that approaches the speed of light approaches infinite mass. Thus the energy required to throw the ball out the train window should be near infinite too...think of it as throwing against the wind of the air passing the train (even though there's no 'air' in space).

You can't go at the speed of light. By definition, the speed of light is a universal constant that is independent of your frame of reference.

If you travel at 0.5c, light will still be traveling at c from you. The same applies at 0.99c and 0.999999999....c. You cannot reach the speed of light, thus you can't go faster than it.

Also, it's not "just" theories. A theory in science isn't just an idea like that, it's a huge process with detailed proofs and analysis. If anything, a theory is much stronger than any other construct of man.

Only particles that have a non-zero mass can only travel at sub-light speed.

There is a theory about particles traveling faster than light, which are called Tachyons.

Those are closer to the common idea of what a theory is (ie a hypothesis, and a far-fetched one at that). Tachyons have this nagging issue that you can't prove their existence or non-existence if we follow current physics knowledge.

Tachyons exist in SW, part of the hyperspace mechanic

"Tachyons" in SW aren't even tachyons. Whoops.

I do believe they are. They're called Tachyons, therefore they are Tachyons.
