As a brief follow-up and second point, time dilation is a fascinating concept, with tremendous implications. Assume a spaceship accelerates at a constant 1 g (in its own reference), it will reach speeds a little under the speed of light from the perspective of an Earth inhabitant in ~ 350+ days. Due to time dilation, the space traveler's lifespan will be increased to thousands of Earth years (when the reference is the Solar System ). However, the traveler's (subjective or felt) lifespan will not have changed.
Upon returning to Earth, the traveler would arrive thousands of years into the future. This is despite the fact that the travel speed (as observed from Earth) would not have ever exceed the speed of light. This is in fact consistent with my original point, though my presentation as a novice in this area may have been very sloppy.
To the average human being, this would suggest that time is quite variant.
