If you had a time machine and went to kill yourself in the past, then you never should've existed in the first place, amirite?

This is called the grandparents paradox, or something.
If you went back in time and killed your grandparents, you would have never been born. But if you'd never been born, you couldn't have gone back in time and killed them.

Also, I've heard another version, where you become immortal, because you killed your grandparents and therefore weren't born, but still exist, and without a birth you can't have a death, or some shit that I can't be bothered to remember.

I read a book about that called "The Power of Un". It's about a boy who meets an old man and receives a time-travel device called the Unner. Later, it turns out the old man is him from the futer. The boy finds a new Unner, and since his old one broke, he has to figure how to give the new Unner time-travel capabilities. It's a great book.

I think a new branch of time is created like on that movie dejavu.

According to the video game Red Rising 3 ... if you time travel and touch something, the interaction destroys the object.

Yet they are able to walk on surfaces without destroying them, so .........
