The part that I always get hung up on is trying to measure your "passage of time" against that of an object that is speeding away from you close to the speed of light.
After all, the passage of time only really matters if we have a strict definition of what is past, present, and future. And relativity tells us that this can change depending on which reference frame you are in.
What purpose does it serve us to compare "our time" against "their time" when they are so far away that we can't even communicate in "real time"?
Is it normal to think Time Travel will Never be Invented
