I have a few relativity questions.
As I understand it, nothing can travel faster than the speed at which light travels (spatially), as all objects have a maximum rate of motion distributed across three spatial dimensions and one time dimension.
Why is the limit of spatiotemporal motion what it is?
Why is the spatial speed of light a constant, rather than one which can be slowed down? Where does light get its energy and why does it not run out?
If I were riding on a photon at light speed, would I be able to step forward while in motion? Would I appear to be breaking the speed of light from the perspective of an outside observer?
If, in the same scenario as in the previous question, I observed everything appearing to be passing me at the speed of light, would it appear to pass at a speed greater than that of light if I stepped in the direction opposite the objects passing me?
If passing the light speed barrier requires an infinite amount of energy, could this be achieved with the infinite mass of a singularity?
If no time passes at the spatial speed of light, would any of my biological processes be active if I were still riding this photon? Would I perceive anything, or would I cease all function?
If two photons are racing past each other, would it appear from the perspective of either photon that the other is exceeding the speed of light?
Say I am observing a white hole attempting to push away a photon traveling in a perfectly straight path towards it. Would the photon, from my perspective, appear stationary?
If light cannot escape the gravitational influence of a black hole (within its event horizon), would a photon traveling straight at a black hole accelerate once within the event horizon or continue at the same speed?
Once inside of the black hole, at what speed does the photon travel?
Thank you very much.
