I have an interesting thought on the universe. I dont know if anyone can answer this?
Right...when we look out into the universe with satelites such as hubble, we see the universe as it was many many years ago not as it is right now because galaxies and stars etc are millions of light years away and it takes so long for the light to travel to Earth.
So if someone was millions of light years away from Earth and they had a satelite good enought to see me on Earth, does that mean that they could see me as a small child when I was young due to them seeing Earth as it was many years ago not as it is right now.
Or if I could travel faster than time itself and get millions of light years away from Earth, could I see myself on Earth as a child?
Does that make sense?? Lol. Ok, im going now.

You could not see yourself as a child because you wouldn't be travelling in time, only distance.
imagine say, as you are travelling away from earth, all of the light from earth is so fast its over-taking your space ship or whatever, its getting well ahead of you, so youre seeing the light as its being produced.
If you INSTANTLY travelled to someplace hundreds of thousands of billions of light years away, the light from that amount of 'time' wouldn't have reached that point yet, so yes you would see the earth as it was that time ago - but only relatively... |

It was in these weeks new scientist
Its a parody on the question "if a tree fell in the woods with no one there to hear it, would it make a noise"
Which I covered last week in my weekly scientific musings - short answer, yes. long answer. of course you retards :) |
