Einstein's theory of relativity says that space and time are linked together. What does this mean for time travel? Well, according to this theory, the faster you travel, the slower you experience time.

Scientists have done some experiments to show that this is true. For example, there was an experiment that used two clocks set to the exact same time. One clock stayed on Earth, while the other flew in an airplane going in the same direction Earth rotates.

After the airplane flew around the world, scientists compared the two clocks. The clock on the fast-moving airplane was slightly behind the clock on the ground.

So, the clock on the airplane was traveling slightly slower in time than 1 second per second. We can't use a time machine to travel hundreds of years into the past or future.

That kind of time travel only happens in books and movies. But the math of time travel does affect the things we use every day. For example, we use GPS satellites to help us figure out how to get to new places.

Check out our video about how GPS satellites work. Or should it? From pushing particles to near-light speed in high-powered accelerators to work on wormholes, efforts to both backtrack and fast-forward are scientifically inevitable.

Will time travel ever be a reality? In some form, probably. Are we on the road to a picnic in the past or a foray into the future?

Until the 20th century, time was believed to be completely immutable and time travel a scientific impossibility.

Until year-old Albert Einstein came along. In , Einstein revealed his ideas on special relativity , using this framework for his theory of general relativity a decade later. The most important being that time is elastic and dependent on speed, slowing down or speeding up depending on how fast an object—or person— is moving. In , four cesium beam atomic clocks flew around the world and were then compared to ground-based clocks.

The resulting minuscule time difference proved that Einstein was onto something. There's also another technology, tucked inside your smartphone, that also validates Einstein's theory. But apart from this mutable version of time, Einstein also calculated the speed of light.

Fast forward a century later, and all of these theories—highly summarized, of course—now form the building blocks of astrophysics, and buried among all this expert-level math, Einstein also proved that time travel was possible.

But what would happen if we created something that could go much faster than geostationary orbit? We are not talking a commercial jetliner to miles an hour or a 21st century rocket to the ISS 25, miles per hour , but something that could approach , miles per second?

It routinely sends subatomic particles into the future. The particle accelerator has the ability to propel protons at
