Looking Back in Time

[China Doll]

Hi All,

Please bear with me, I think I'm about to ask a set of really stupid questions here but I am genuinely interested in this and am not sure if a friend is pulling my leg or if he is just talking out of the proverbial.

We were talking about time travel last night (as you do) and he told me that if you were able to get to the furthest star (possibly planet but I think he said star) from the earth and had a powerful enough telescope you would be able to see dinosaurs on the earth. The reason for this apparently is to do with how long it would take for light to reach the star you're on, hence you would see past images as opposed to current one. My first question... is this even remotely true?

Also, if it is true, would it ever be possible to actually do this? Is this a way that we could actually travel back in time so to speak?

(If I've had my leg completely pulled, please try not to laugh me out of the science thread completely!)

Cheers China xx

The idea of the wormhole is a serious proposition, China Doll, not a Hollywood invention.

well china, there is nothing to disprove the theory of worm holes, ad scientist are costantly finding weard thing in space, so, in theory worm holes could exist. we know that black holes exist, altough no body has ever gonenear one, and most probbably will not in out life time, but they could be a "port hole" to another parto f the universe....... intresting, you are very curious to day.
