why is looking through a powerful telescope like looking back through time?

    Because the light you are seeing was emitted a very long time ago.

  • space - ,

    If you were to see light from a star that is 1,000.000 light years away, you would see the star as it looked 1,000.000 years ago (by the time you get to see it, it might not even exist anymore.)
