The discussion centers on the nature of spacetime at light speed, specifically whether there are four isotropic axes of spacetime when traveling at the speed of light. Participants explore the implications of speed on the perception of time and space, addressing both theoretical and conceptual aspects.
Participants express disagreement regarding the existence and nature of isotropic axes at light speed, with multiple competing views on how speed affects the perception of spacetime.
Limitations include the lack of consensus on the definitions of isotropic axes and the implications of relative motion on spacetime experience. The discussion does not resolve the mathematical or conceptual steps involved in these transformations.
brianhurren said:below the speed of light we experience one axis if time and three of space. So at the speed of light the space and time unify and we get 4 isotropic axes of spacetime. 4 identical dimensions. is this correct?
Why does there have to be an observer at the spatial origin of every frame? When we transform from one frame to another, there is no observer at the spatial origin of the new frame, not even conceptually.Nugatory said:No.
You should consider that you are always at rest relative to yourself so no matter what your speed is relative to someone else, you get the same four axes and the same experience as someone at rest. Right now you are moving at .99999c relative to some observer in some far distant galaxy somewhere... does that affect what you're experiencing or your notion of how the space and time around you is behaving?
