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.

I have often thought that it would be impossible to travel forward in time, i.e. travel in to the future and only possible to travel back in time because the future has not happened yet.


What I always found interesting about this notion is this:

If it's impossible to travel forward in time, then it should also be impossible to travel backward in time because if you were to travel backward in time, you would enter into a place where the future you came from doesn't exist yet. And if the "future" that you're travelling back from doesn't exist yet, then you can't be travelling backward in time from it.

So essentially, travelling backward in time should undo all reality from your current position in time forward, if it's not possible to also travel forward in time. If this is the case and we do discover backward time travel, we could rewrite history, or perhaps even undo mankind as a whole.

ie: someone from our "future" traves back to this time, making this the new most forward place in time. Then we harness this time travel technology, and travel further back into time, and the process repeats itself. This is of course if reverse time travel doesn't just disassemble the time machine and cause the time traveller to regress to infant/embryonic states.

Maybe, but the future you are traveling from does exist because you are coming from it.

The shortest man made event is a 50 (ish) femtosecond laser pulse. It is also the shortest possible timespan to make observation in (yet). I know this, for if it wasn't I wouldn't have my PhD Research...
