Time is relative; maybe well based on relativity, it’s contingent on the speed you are moving relative to someone else. So, if you’re going at the speed of light, you are going to be moving through time slower than a person on Earth. Which is pretty cool when thinking about how to make time travel possible. But then again, if you really think about it, we are all moving close to the speed of light relative to the center of the galaxy.
Just consider: we are on a planet that is spinning around, then it is moving around a sun. Now, our solar system is moving through the galaxy, which is then stuck in an orbit around the center of our galaxy, and our galaxy is moving through our universe. All together, we are moving quite fast.
So, thinking that way, time may not be relative to what we know as the center of the universe. There may be a different time clock for the universe, and we are moving relative to it, or we are moving relative to the center of the universe.
Now, does that mean time travel is possible? Well, maybe let’s go with yes and no. Leaning to no because there are lots of paradoxes that say it’s not. But the main one that I think about as to why time travel is impossible is one that is actually very logical in comparison to some of the others.
That is the need for time travel, which is basically whoever invents time travel has a reason to do so. And when they do, they will solve their reason and erase their need for time travel. For instance, a person’s parents die in a car crash, so they work for years to invent time travel to stop the crash. Then they do just that: invent time travel and stop the crash. Now what? The reason is gone, and so when time ripples and fixes itself, then they never invented time travel.
Now we come to the unknown, scarier part. What if when you go back in time to fix a problem, time doesn’t allow it; instead, it backfires. You are pushed back to your own time? The introduction of matter from a different time isn’t allowed; all matter from the foreign time is pushed back to its original time. Also, there is the possibility that all matter that doesn’t belong gets pushed out of time both in the future and the past, meaning once that person tries to go back in time, they are just removed from time altogether, and they never existed.
Then we have the possibility of the complete collapse of time and matter itself leading to a big bang event that resets time and the universe as we know it.
There is also the possibility that one attempting time travel, it just doesn’t work; you can view the past but never anything else. Looking at the past is like looking at a TV, and that’s it; you can’t touch it, but you can see it.
That’s actually the best case of the whole time travel thing, but I think it’s about time to stop. We aren’t going to do anything good with time travel, and it’s more like a nuke on crack in danger level. There are actually a lot of things that could go wrong and even more that can destroy the universe and all life as we know it.
Then, like all things, once it’s done, comes the misuse, time bombs, and destroying time with so many downsides like time leaks that mess with time randomly. Or even deleting things from time, causing ripple effects that can destroy everything as it ripples like a tirade wave of doom.
But who knows; it could be all roses and fun just like the H-bomb.
