Perpetually Offended
I've always been fascinated by science, ever since I saw a picture of the Martian surface in a school science book in elementary school. It's always made me want to learn more Especially if it's something not easily understood.
Take, for example, quantum physics or theoretical physics and Avengers Endgame.
The typical stance of pop culture regarding time travel is that if you go back to the past, you change your future. And then some vague explanation of "The butterfly effect"... Like Back to the Future or Terminator.
However, Avengers Endgame ACTUALLY gets it right. IMO.
Take the grandfather paradox. You go back in time to kill your grandfather so that you're never born. But if you were never born, you couldn't have killed your grandfather. But what would happen is, once you step back in time, you create a branch in time... A parallel universe. It doesn't matter if you end up killing that version of your grandfather... You've effectively left your own timeline and created another. So, as Hulk said, your present becomes your past and your past is now your future.
So instead of changing your past, or anyone's past, your actual past is intact. You were still born. Your grandfather never died.
I find things like that so fascinating!
