Can anyone find flaw with this logic of future technology?

Asked by tedd (14078points) November 3rd, 2011

So I was thinking about it after reading an article about finding alien life or other habitable planets. Basically one of the highlights of the article was an often-taken-for-granted fact that light travels slowly relative to the size of the universe. Though you may look up in the night sky and see a zillion stars, half of them may have died out more than 1000 years ago… but thanks to the speed of light being so slow, you’re still seeing the light they emanated however many light years away they are. For example if star Z is 100 light years from earth, and it blew up today, you wouldn’t see the explosion on Earth for 100 years.. it would be to you as if the star was perfectly fine.

Well another highlight of the article was how improving telescopes and related technology is allowing us better views of planets that are far off. Now granted at the moment better means we can see them as a small dot with their star as a back drop… but that technology is constantly improving, hence how we can actually see that much now.

Then I got to thinking, what if we combined these technologies in the future. Isn’t it entirely plausible that at some point in the future, we could have a “telescope” powerful enough to see the surface of another planet as though we were looking at it from merely a few meters above? Think of how powerful our satellites in orbit are already. What if we found a means of transplanting one of these satellites, several hundred light years away from planet Earth, and then pointed it at Earth, to view the incoming light? You could potentially have an eyeball into the past.

If today you were 235 light years away from Earth and in possession of a telescope capable of looking at the surface of our planet with google-maps-esque quality satellite imagery… you could literally watch the opening of the American Revolution as though it were happening right now.

Obviously there are huge leaps and bounds that would need to be surpassed before this would be possible (traveling faster than the speed of light for example).... but given the belief that the core technology requirements will someday be achievable, is there any reason to think this won’t one day be a possibility?
