it is really one of the basic physic principles that is taught in the high school, so i have no idea what kind of physic’s school would not teach that.

Oh no, have you used the word relativity too many times and now you have no more arguments? :D

If you could reverse time travel then the space would conform to the time you travelled to.

Really? What else would conform to the past point in time? Would fabric in my clothes disintegrate and transforms to something else? Would I, because I, well, didn’t exist in that past? Then it wouldn’t really be time travel, would it?

Or would the clothes stay, because they are mine and important for me and would I stay on earth, because that’s my baseline? Is universe somehow “me-centric”? Not really likely, is it?

You need to abandon your idea of time travel as seeking in a video with rewind button.

According to our current understanding of physics time travel is impossible, but we are talking about a word where it is clearly possible, so you can’t really constraint yourself with the limits as we know them now.

There is no cosmic frame of reference

There is. Just because we can’t correctly find and use it with our knowledge doesn’t mean there isn’t.

it’d be really silly

What would be silly is thinking that earth is some magical center of the universe… We have abandoned this concept about 500 years ago.
