Is it true that when you travel in space you can see the past on earth?

my cousin took astrology in highschool and her teacher sid that when you travel through space the farther you are away from earth the world looks younger like you can see dinosaurs or something

NO it is not true!

hahahahaha, i think they were having a laugh dear!! you cannot turn back time, even with space travel

Nope, that was a joke. You can only see PAST the earth...

Short answer - no.

It IS true that when we view very distant objects we see them as they were in the distant past. For instance, a quasar that is 8 billion light-years away appears to us as it was 8 billion years ago. But moving away from the Earth does not cause this to happen. If you traveled 10 light years from Earth, then looked back, you would see the Earth as it appeared ten years ago from our point of view. But since FTL travel is (as far as we know) impossible, you can't get ahead of the light that left the Earth in the past.

If you could travel faster than the speed of light and had a powerful enough telescope then yes it would be true! The light we see from stars is old, some of them no longer exist! Unfortunately we can't travel faster than light and there isn't a telescope that powerful...LOL

You mean 'astronomy', right? Astrology is the defunct Ptolemic nonsense that is in the papers...

One can't see dinosaurs from the void in space...but I have heard it said that when one looks up at the stars, the light you see coming from them started from the time of the dinosaurs, and is only reaching us now. "You are looking into a vast time machine", as Richard Dawkins put it.

That been said, have you seen how big Mars is up there?

There was a theory about travelling in space faster than the speed of light that basically said something along those lines. But it was based on the fact that you were travelling faster than light and would therefore get ahead of light from the past. But it has never been proven as we can not travel that fast... yet.

time is time and moves at the same constant speed. So ask teacher where they got their facts from.

I would be VERY concerned about any schol ofering astrology as a subject.

first: your cousin took ASTRONOMY, not that other stuff with the crystal balls and incense.

second: i hope the teacher was doing a 'thought experiment' saying something like... "If we could travel faster than light and zipped out to 1000 light years from Earth and pointed a VERY BIG telescope back at the Earth, we would see our planet as it was 1000 years ago."

Otherwise... even if you could travel AT the speed of light (and you can't) if you traveled 1000 light years from Earth you would see the Earth as it was when you left. Not earlier.
