We are all
time travelers. We are on a never
pausing spaceship traveling into the future.
Einstein postulated that if light speed is constant then time is not. If time is not a fixed standard, then it will vary by the speed of one object moving away from another.
RELATIVITY
An astronaut leaves Earth traveling at 8/10 the speed of light. After 30 years on the spaceship, 50 years will have passed on Earth.
People belonging to the know-nothing party, which is the base of the Republican Party, will say that Relativity, like Evolution, is just a theory – somehow they will weave god into it.
But time travel is a
standard calculation that allows GPS to operate and allows us to land a space
probe or ship with precise accuracy on another planet or moon.
Time is
bendable and can be affected by gravity, opening the possibility of wormholes,
but that is another formulation.
To my way of
thinking, time is truly relative to the individual. When I was eight years old the time between
one Christmas and the next was an eternity.
Now in my eighties, it seems I wake up and another month has
passed.
Then perhaps
this is all just a simulation. Zeus's son is
playing a computer game and we are just avatars.

Warp speed, Mr Sulu!
