This doesnt make sense though. The light you are seeing from 13 billion years ago has travelled 13 billion light years and is in your present. If you travelled to the source instantly it wouldnt be there it would be hitting earth...
If I saw a 13 billion year old explosion now...

As said it all depends on the method of how you travelled to your destination. If you instantly teleported then you in effect didnt actually travel...you just "warped" time space to get there....Warping space to conventional travel means is different.
Warp travel is more realistic(!) than travelling via ftl travel as you just warp space to get to your destination, rather than using motion to get there...if you see my point...sorry way off topic :X

Hmm yeh.
I love this stuff, but obviously my intelligence regarding this topic is limited
So everywhere is the universe is present ?
I need to sort an argument out.
The world is 13 billion years old. An explosion 13 billion light years away happens when the earth is created. (this 'explosion' is not the creation of the earth, is it just an explosion that happens in space, creating light. It could be a collapsing star or some sort of collision, either way it has nothing to do with the creation of earth)
Now fast forward to today. If I see that explosion in the night sky tonight and use a teleport machine to teleport me to that place where the explosion happened will I be in the future or in the past?
I say future because it happend 13 billion years ago. So if I am there then earth is 13 billion years behind me.
Or is it even the present?
My head hurts
You'd be alone. Far, far away. Probably minus your teleporter device. And colder than a Scottish hobo. In the present.

I don't see why not. I don't understand how time travel as a concept can be believed. If you shine a torch at a wall 1 light year away, then fire your super rocket at twice the speed of light at the wall you would beat the light to the wall. This does not necessarily mean you have travelled back in time because the light is still travelling toward the wall, so the light has already been generated. It just means that you have overtaken the light.
It's like passing a car travelling at 50mph on the motorway at 100Mph and reaching the destination twice as quickly. Just because you beat the car it doesn't mean you travelled back to before the car started its journey. It's all about perception of time. I can imagine that to the observer you travelling faster than the light you have produced and appearing at a location before the light you have generated reaches it would appear to be time travel, but its only light being slow in my opinion.
iirc the current theory is the faster you go the slower time runs for you.
the atomic clocks on the space station are slightly behind because they travel at 10's of thousands of miles an hour all the time.
I don't think everyone is in agreement about what happens once you go past the speed of light but then it;s been ages since i read up on any of this.
You are in the present, the light is in the present, but it has been traveling for 13 billion years. The area of space where the explosion happened is in the present, but you cannot see its 'present' state from Earth for another 13 billion years.
If an alien picked up the TV broadcast of JFK getting shot and then teleported to Earth, would it be 1963? No.

No, the only place where the present exists in Space-time, is the point from which you observe it.
Everything else is relative to that point, for that observer. Space and time are different, for an observer in any other point in space-time
It's all Relative to your observation point.
