The grandfather paradox
Imagine you had a grandfather that you never really liked. One day you went back in time BEFORE he met your grandmother and pushed him off the grand canyon. Would you live? He had never met your grandmother which means your not alive, but he did meet your grandmother because you're alive. so you would never be able to push him into the grand canyon. That shows that in the future you might not be able to travel back in time, and if you can, you won't be able to touch or talk to anyone, and they won't see you. but it's still possible to go forward into the future.
possible ways to time travel
There is many ways to time travel, and here are some of the most popular ways to.
1. Black Hole. the way of traveling by black hole would not be actually going inside of it, unless your main reason for existence is to turn into a noodle. If your not looking into be spaghettified, you would actual be traveling around the outer ring. 2. warp drive. the idea was proposed by theoretical physicist Miguel Alcubierre, to actually create a warp bubble around a spaceship that almost raps space around it. the idea of a warp bubble is that it would expand space behind it and contract space in front of it, pushing the spaceship forward faster than the speed of light. 3.wormholes. proposed by Albert Einstein, 5. tipler cylinder. the idea is to make a cylinder. |
