Physicist May Have Solved The Grandfather of All Time-Travel Paradoxes - Lemmy.World

I thought there was an understanding of infinite timelines already. You can never change your past. As soon as you do, it is no longer “your” past. It is now another you’s past. That’s why time travel is useless unless it’s not you changing your past.
That hasn’t been proven yet. All of this shit is still theoretical. AFAIK, time travel into the past isn’t possible in our current understanding of physics.
