Very Powerful Telescope to see 10 light years away at high resolution...

  1. May 18, 2015 #1
    Lets suppose I had a very powerful telescope and I could see 10 light years away. Would I see cars and people on that planet as they were 10 years ago? Would I actually see the people moving and the cars moving on the ground?

    This isn't a relativity question. Physicists from 1700s (perhaps even earlier) would have told you yes, and yes*. This only depends on finite light speed.

    *You might need to clear out dust from space and have an aperture much larger than the solar system, but whatever, that's fine for a thought experiment.
