Isn't Time Dilation evidence that time is a dimension of the physical universe? If we can effect the speed of an object through dimension t, it seems like we're actually interacting with a physical construct of the universe, and not just some abstract a priori notion of convenience (but again, I'm no scientist, so I'm probably wrong :P).

First you have to define time. I see it as no more than the delta between configurations.
A bouncing ball has no inherent property of motion. Each successive image captured by your eyes builds on the previous image to reinforce the sense that the ball is moving. There is nowhere that the ball exists previously to the considered moment, other than as a memories in your mind and maybe the air molecules it interacted with.
Time dilation is a difference in the measured rate of time between two entities, hence the term relativity.
The timeless theory is more aligned with quantum logic, and does not require a pre-defined shape space within which to operate. |
Yes, but as I stated above, couldn't you make the same argument for
space (I had no idea there were so many Kantian's here :P)? The only contemporary physicist I've read who endorses timeless theory is Julian Barbour, so I can't claim to be an expert on the subject.
I should state I'm a Presentist, a theory where time exists, but only the
present moment of time has ontological status, the past and the future are non-existent.
