Is Rearranging Every Atom the Key to Time Travel?

AI Thread Summary
Time travel is deemed highly improbable due to the immense complexity of rearranging every particle in a person's body simultaneously. The concept of storing detailed information about every atom raises significant technological and ethical challenges. Additionally, the body's continuous changes and loss of cells complicate the recreation of a specific physical state. The theory that time slows down at the center of a black hole remains unproven and poses insurmountable survival challenges for any living being. Ultimately, while time travel captivates the imagination, it remains firmly in the realm of science fiction.

People say and have decently backed up that time travel is not possible by saying that you would have to rearrange every particle back to where it was. Instead of rearranging the particles of everything. What if u could take all the information and I mean every aspect and formation of every atom could be written down. What if you used the information you found out that was every part of ur previous body. step into a machine, and if possible re-arrange every single particle of the body at the exact same time. But since you lose blood cells and other stuff from getting hurt. It seems like its near impossible even though i have the concept down. This again leads back to time, "the 4th dimension" If we could find a way to negitate time it might work. If it is true that in the exact center of a black hole, time slows down and maybe comes to a stop. Based upon that, and with information that could come out in the future It might ill take care of it :)

Everyone ignore this thread I posted in wrong area.
 


While it is an interesting concept, the idea of rearranging every single particle in a person's body at the exact same time seems highly unlikely. Not only would it require an immense amount of knowledge and technology, but it also raises ethical concerns about altering a person's entire being. Additionally, as you mentioned, the constant changes and loss of cells and other elements in the body would make it nearly impossible to recreate a person's exact physical state at a specific moment in time.

The theory about time slowing down in the center of a black hole is also just a theory and has not been proven. Even if it were true, the extreme conditions in a black hole would make it impossible for any living being to survive, let alone have their particles rearranged.

It is understandable that the concept of time travel is intriguing and has been explored in science fiction, but at this point, it remains just that - fiction. The laws of physics and the limitations of technology make it highly improbable that time travel will ever be possible.
 
Hey, I am Andreas from Germany. I am currently 35 years old and I want to relearn math and physics. This is not one of these regular questions when it comes to this matter. So... I am very realistic about it. I know that there are severe contraints when it comes to selfstudy compared to a regular school and/or university (structure, peers, teachers, learning groups, tests, access to papers and so on) . I will never get a job in this field and I will never be taken serious by "real"...
Yesterday, 9/5/2025, when I was surfing, I found an article The Schwarzschild solution contains three problems, which can be easily solved - Journal of King Saud University - Science ABUNDANCE ESTIMATION IN AN ARID ENVIRONMENT https://jksus.org/the-schwarzschild-solution-contains-three-problems-which-can-be-easily-solved/ that has the derivation of a line element as a corrected version of the Schwarzschild solution to Einstein’s field equation.
