Counting Stars

So, tonight I was letting my dog out together with my dad and it was a beautiful clear (and cold, brrrr) night. Thousands of stars were clearly visible and we started talking about the fact that most of the stars we could see had 'died' millions of years ago, though for us they were still there, a kind of creepy idea when thinking more about it. Actually we were looking at the past, we saw things that ceased to exist ages ago and it brought us to the famous question (one that I have been wondering about since I was just a mini-Louise): will we ever be able to time travel and if so, how? We found one theory that sounds pretty reliable. here it comes:

So in the first place, astronauts will have to travel to a place millions of kilometers away from here. One must: they should travel with an even higher speed than the speed of light, only then  They land and look at the earth. At this point they are in the same situation as dad and me, but then reversed: they look at the sky and see a minuscule little dot (the earth) and the great thing is: they are looking at the earth's past! It is because the light has not traveled fast enough to bring the present on earth to this place, so there is a bit of delay. In order to also actually see something they should bring a giant telescope with them, one strong and powerful enough to see what's going on at planet earth (some day scientists will succeed to make one like these, I hope). Who knows what they might see! They might see dinosaurs passing by or witness the famous battles between the Romans and the Germans. It would be absolutely amazing! The idea is so simple, it might be a little difficult to put it into practice, though. Even if humanity ever succeeds to make something (other than protons) travel with the speed of light, it will be a real challenge to make it go even faster than that. And even if it in someway would be possible, than I don't quite think the astronauts would survive the trip due to its high speed. Maybe super-high-tech robots would, but I'm afraid it will provisionally stay a little-girl's-dream,.
