Nothing mathematically seems to forbid time travel...but the second law of thermodynamics might have something to say about that. My main argument against time travel being possible is the fact that we have yet to be invaded by time tourists from the future. On the other hand, I find the Mandela Effect concerning since I've personally experienced quite a few examples of it.

That being said, I've always hated time travel as a plot device. Here's why. You've discovered a method for time travel. Congrats. You're invariably going to squander this ability by doing something foolish like killing Hitler. Stop the sackings of the library of Alexandria if you want to be useful for starters. The Hitler thing worked itself out organically already. Go after the thing that set human knowledge back to the last ice age.

That being said...the even bigger issue I have with time travel as a plot device is this. Let's say you want to go witness the signing of the declaration of Independence, or the assassination of JFK or something. Great. Get in your time machine. Set your trmporal coordinates, and...enjoy materializing in the cold, black vacuum of space.

Hell, jump back to like 5 minutes ago when I started this post...enjoy either popping into solid Earth, or black void. In just 5 minutes, the Earth, the solar system, and the entire milky way galaxy has moved thousands of miles in several different directions from the spacetime coordinates you've left. It's a little different if you're already in a space ship when you jump, but you're still going to have a bad time playing catch up to the spot you left. If you're in something like the BttF Delorean, good fucking luck.
