Ok so my next question has 2 parts, but i wont go into the philosophical part here. But i was reading about a letter albert einstien wrote to a person regarding the death of a friend. As i tried to understand his meaning behind it, i started thinking. From what i am told time is affected by speed, mass and distance (i.e. a small slow movement here would have a massive change in time billions of lightyears away from here). Would it be safe to assume that there is and always will be a point of reference in this univerese where we will all be alive, dead, and yet to be born here on earth? I hope that came out right, as i am having a bit of trouble putting my thoughts to words. Again, i have no knowledge in any of this material, only genuine questions. Please excuse my ignorace.
