Thanks for pointing that out George. If I had said that we measure light to be traveling at c in any IRF would that have been correct? James

I asked a similar question here https://www.physicsforums.com/showthread.php?t=677194. I think it is an interesting question, but I'm no physicist. We observe light traveling at c not matter our frame of reference. Is this fact telling us something in addition to SR and GR about the universe? It...

I've got a LOT of study to do before I ask anymore questions so this isn't a question :smile:. I'm interested in transforming from 3 spatial dimensions plus time to 2 spatial dimensions plus time. I've done some googling but didn't come up with what I was looking for. It's just a curiosity and I...

Thanks George and Zz.

I am trying to gain some understanding of what SR 'tells us' about the universe. The following statements are made from the imaginary perspective that light would have. Are they correct? 1. A light wave observes no time passing for any matter. 2. The light wave is absorbed or is at the...

I think the cause of some people's confusion is the phrase "nothing can travel faster than the speed of light". We see this statement in the media now and then. I believe it would be better to say "matter cannot be observed to be traveling at or faster than the speed of light". An unmanned...

Instrumentation on the ship would enable the observers to measure any distortions in space/time :smile:. For the thought experiment we could say there is only the ship and uniform space/time. I'm not attempting to argue that there is something wrong with relativity. The only observers are on the...

Thanks for the replies. I understand that the ship cannot be observed to be traveling at or faster than c. All observes are on the ship and they can measure the acceleration of the ship. Is it true to say that after a period of measured acceleration (measured by the observers in the ship) the...

Would it be correct to say that matter cannot be observed to be traveling at or faster than the speed of light, however, it is theoretically possible to increase the velocity of a spaceship until the velocity is well beyond the speed of light when compared to some initial velocity? Note, I'm not...
