reply to post by Lebowski achiever
I wrote this a while back. Think it is apt here:
Time is an eternal moment of now
Albert Einstein has been credited with the above statement.
What he meant by it is that there is no past. Only the traces of it which are left in your brain. There is no future. Only a concept of what the
future might be based on past experiences.
That's not what he meant.
To understand what he did mean, think about space.
There is a place you are: a point in space. Call it Here. You cannot experience the world as it must be from any other point in space; you only know
what it's like Here. You cannot know (except by report) what it's like over There.
And Here moves with you. You live, so to speak, in an eternal point of Here.
It's the same with time. The past exists, back Then.
And the future exists too. You haven't reached it yet, but it's there.
But you move through time in your eternal moment of Now, knowing nothing (except from memory) of Then and nothing (except by extrapolation) of To
Be.
Spacetime is a landscape with four dimensions, one of which is time. Everything in the universe is laid out along those four dimensions. Dimensions
don't appear and disappear; they are eternal. And so is the universe that exists in them.
