The Parallel Universes of Time Travel

Time travel. Amidst the many supposed time travelers, modern science isn’t able to completely debunk all these conspiracies and confirm an answer to the question: “is time travel possible?”

Time travel. You know, you step foot in a long box-like machine, there’s a loud whoosh, and you’re conjured up in an ancient or futuristic dimension. It’s definitely something you’ve heard of before.

Popular sci-fi films center around the aspect of time travel and it’s even been one of the most famed conspiratorial topics for decades. Yet, would you believe me if I said it was possible to bring it to life?

Probably not. Right?

Well, in fact, you’re wrong. Partly wrong. We already have quite a bit of information thanks to Einstein and his theory of relativity. However, his methods prove to be lethal to anyone who would try to undergo the process.

However, throughout history, we have seen cases in which supposed time travelers venture through different dimensions of time. Different parallel universes. And they’ve all undergone the process and made it out alive. And by modern science, this is impossible.

And that’s where the trilemma is presented. Should we believe modern science which deems time travel practically impossible or should we consider the cases of numerous time travelers throughout our history? Or is there perhaps a neutral stance? Well, let’s find out.

Time Travel is Basically Impossible:

Many people, back before Albert Einstein came into play, believed that time was constant. It was the same for every single being. And Einstein proved this wrong.

Einstein’s theory of relativity states that time slows down or speeds up depending on how fast an object moves relative to another. He theorizes that when mass is placed on the four-dimensional arena of space-time, it will bend that fabric, causing objects to move in a curved path called gravity.

Einstein’s theory of relativity was proven by our GPS satellite technology that revolves around the Earth’s atmosphere: these satellites, which have extremely precise timepieces onboard, move faster than perceived by humans on the surface. This, adding to the effects of gravity, makes the satellite travel slower through time, adding 38 microseconds a day to uncalibrated clocks on Earth. So hypothetically, if a person resided in the satellite, they would be very slightly younger than everyone on Earth.

We could conjure up another hypothetical scenario without taking the realistics into consideration. Let’s say an astronaut in a spaceship was traveling at a rapid speed, approaching the speed of light. Time would theoretically move slower for them and they would return to Earth slightly younger than a hypothetical identical twin that remained on Earth.

This occurrence is called time dilation. It’s a very slight adjustment yet nothing close to the immensity of time travel.

This technically means that scenarios, in which travelers would go back or forth in time, would actually exist. However, these do have a few limitations.

The first scenario would require an object to travel faster than light (to put it into perspective, that
