@
beckyromero either one you would have the problem of matter recreation.
No two pieces of matter can be the same. They would destroy each other. Now I might not exist in that time frame, yet the matter that I am made of most definitely does exist then.
Other physics laws apply. Like matter popping in and out of the universe. Causing more matter to exist in one time frame than the other.
How can there be more matter in the past than in the future? 🤷🏻♂️
Matter does not cease to exist. Even in a singularity it only becomes denser.
To my knowledge none of that has been explained. It would throw off all kinds of physics laws.
Imagine a universe where a singularity popped in from the future. Instantly collapsing the universe as it was formed at the time of the big bang.
No universe!
Or better a whole universe popping in from the future to a past universe.
Now it's been claimed that that something from the past can go to the future. There's actually a mathematical theory on that.
Yet even that has problems with instant matter recreation.
Dimensional shifts? Same problem. How can even the air exist in the same place at the same time as your own body? 🤷🏻♂️
A complete vacuum does not exist within this universe. There's always photons of light within the universe.
A votex of some type? Then you have a exchange of matter. What was in the past is in the future and what is in the future is now in the past.
Now you have the problem of past matter in the future and future matter in the past.
Think what that would do to carbon dating? The half life of the carbon would be older from the future in the past. And younger from the past to the future.
You would have to change ALL the physics laws we know of to even allow for time travel.
Even gravitational laws, since there would be more or less mass one way or the other.
