Of course the Lorenz factor might be wrong. You want to try to prove it?
Aren't you saying what I said?
Your argument ignores the experimentally verified model used by anyone wo ...[text shortened]... Lorenz factor does not exist. That does not fit in with experiment.
Please explain it.[/b]
You and I are on the same side of this, I think. My comment to you is simply that you're right even if the object slows down for some other reason than a collision; for example, gravity might slow it down, but then the other object would shoot up to light speed due to the infinite energy transferred.
Please explain "it"? What is "it"? The Lorenz factor?
Originally posted by adam warlock I know energy must be conserved.
If you collide with something you'll impart some of your energy to it. That's all I said.
No, you said that energy release should be considered only because we're discussing a collision. That's not true.

(oh, and I just realized I got the equation wrong, the square root...)
Mr. E's lack of excitement means nothing. He believed Quantum Mechanics was garbage.

How my argument disproved or neglected something. I think that on my first post I openly stated that we were discussing an impossible situation according to today's knowledge. But also said that we could have a sort of hypothetical arfumnet over it.

P-
it could simply be a flaw of measurement.
what you are saying isnt that light through xenon gas traveled faster than the speed of light. i understand it as traveling into the past. which is SF.
"registered on the other side .0000000000000000000000003 seconds earlier than when the light was emitted." if it hadn't started its journey how could it have already arrived? what if it would have changed my mind .0000000000000000000000003 second before pushing the button? would it have still arrived?

It wasn't an error in measurement. It was a measurement of a phenomena well known, Phase velocity. Phase velocity can indeed be faster than C but cannot be used to transmit information. Google it, there is lots of info on it.
Originally posted by FabianFnas I was about to pose this question in the Posers and Puzzles Forum, but when I saw this new Forum (Thank you Russ!) I bring it here instead.
What is the highest possible velocity in normal space and with things with mass?
I say there is no highest velocity at all, what do you say?
according to the einstine equation if we keep the mass constant, then energy will be directly propotional to the square of "c" the n to reach to this velocity is imposible because this amount of energy is almost impossible to obtain.
Just a question-- a Jeopardy! question last week said that physicists had discovered proof of a "tau neutrino". Did I once read that neutrinos move at speeds faster than light? Or am I just mixed-up as usual?
