Is the past a physical and temporal location that exists 'now' and theoretically can be travelled to or, is time simply an illusion to account for our discrepancy between events that have happened and those that are happening. i.e. Cause and effect.
For example, you can 'slow' time down the faster you travel so that a clock on a space ship travelling at say, .5 the speed of light would be running a lot slower than a clock on Earth. But is this really time itself that has slowed down or simply the effect of increased mass on the workings of the clock (and everything else) actually slowing down cause and effect itself?
If you could somehow be on that spaceship but surround yourself with a field of some sort that would allow your mass to remain stable no matter how fast the ship travelled, would you still experience the same rate of time passing as your shipmates?
As I'm not too keen on this theory please show me how it is not the case as I much prefer the idea of time being a dimension and the past and future already existing somehow.
