In many movies and books, time travel is wondered upon, is marvelled at, is thought about as a prime luxury far ahead in our futures, but what most don’t think of, is that time could cause the existence of us to corrupt. Let me explain before your brain confuses itself.
In fantasy, you see a person have a time machine, and being perfectly normal after a ride to the past or future (talking about this in the next paragraph). Don’t you wonder how a human being can travel in a spacetime geometry that goes faster than the speed of light and remain unharmed? They would be traveling in cosmic strings, traversable wormholes, and Alcubierre drives. Their faces would most likely be disfigured at the end of it.
I remember someone once saying that if time travel existed, then you would only be allowed to travel back or forward a certain amount, like say you are only allowed to travel back to the past up to point after time travel is invented, and for the future, I can’t really think of an example. This would be an extreme boundary and wouldn’t allow us to completely experience our ideas of the past or future.
In addition, what if when you want to travel back to your present, you get taken to an alternate universe with slight changes, but you don’t notice. Every time you travel in the past, you create a universe and then when you travel back, you stay in that universe. All these universes would need a place to stay, so the entire universe would be filled with thousands of unwanted universes.
Relatively, what if time travel doesn’t exist because time itself doesn't exist. What if it’s just an idea formed by us to give a term to the changing present? Even so, what if our idea of time is incorrect, and something else, something massively important, is hidden in the universe and we still haven’t discovered it.
