If we are seeing now, light images from a star 10million light years away, then if we were able to travel fast enough(thousands, maybe millions of times the speed of light) we would be able to see what was occuring on earth a very long time ago. Obviously would need to take a mega-powerful telescope to be able to see back, but is a theory which occurred to me just now.

if time travel was ever possible , the future has already happened and people from the future would be with us now

no, not necessarily with us, but using my theory, able to see what we are doing. As they'd be billions of miles away but could see whats going on.

thing is, light travels at 300000000 meters per second, how far would you have to go to see a minute into the past?
The time taken getting there would mean you're just gonna see yourself arriving

No, think of it the other way around. If you were that far away and could travel that fast you'd still only be seeing stuff in the present. Light we see from the stars has taken thousands or in some case millions of years to get here. It's all in the past and some stars have burnt out long ago and if we could travel that quick we'd only see what's there right now, nothing.
Being millions of years away from earth and travelling back at whatever light year speed would still only get you to the present.
What I find the hardest to grasp is the concept of the 'Infinate' universe. Infinate is too hard a word to grasp you are always expecting an end. If the end was a giant wall, what is on the other side of the wall

yeah when u go back or forward in time (not sure which) when u travel at about the speed of light. Some radom scientists did it with a very fast probe plane in the earths atmoshere and when it landed it had gone forward in time about 0.00001 of a second.

Wat, if we managed to travel to a star 10 million light years away how would we see the earths present???
The light would take 10 million years to get to us so how wud we see the present???
Or wud we see the earths present but us just being 10 million light years ahead??

They took an atomic clock on a plane. Was America to Australia or a long flight anyway. The clocks where fractions of a second different when the plane landed. This proved that time is relative and not absolute.

but what about the back to the future theory where if u went back and killed ur decendent then u woulden't have existed then u woulden't have gone back and killed them and so on....

There are infinite parallel universes. So that paradox can never happen.

what's warp speed? isn't that speed of light. techincally wouldn't people from star trek be able to do time travel then

That's a old theory - not your theory.
but yes... that idea is true... Though you wouldn't be able to see yourself like when you were a kid or anything lol ... you'd see a blob that would look a bit like earth.

Paul, ok, so someone else has thought of this before, im not surprised, but occured to me yesterday. If there was a 'cope powerful enough, should be able to see?

i don't believe it will happen as time is a creation that humans have invented.
so are speeds, these are our way of measuring things
