Whenever we think of time travel, we automatically view a complex machine that pushes us into the past or into the future. This is precisely why the concept seems impossible, at least for the moment. However, what we often ignore is the fact that time travel is actually possible. Instead of using sci-fi machineries, all we need is a rocket.
Time travel has actually been achieved in a way
Albert Einstein was the first one to ponder the idea of time travel. He developed the theory of relativity, claiming that, depending on the speed of your movement, time can be relative. Therefore, if you are moving in outer space at great speeds, you are moving a lot slowly through time.
Time travel sounds so complicated in movies because it is a concept we are not so familiar with but, in fact, it is quite possible. There have been many people who have traveled through space. This means they have experienced the phenomenon in a way. All those people who spend time on the International Space Station are travelling at greater speeds than us on Earth. This means that time is passing slower for them than for us.
Just like some sci-fi scenarios have suggested, spending a long period of time in space can really distort time. For instance, when returning to Earth after such a period, you will actually be younger than a person of the same age who has spent all this time on Earth.
Our concept of time travel is really hard to achieve
In fact, scientists have succeeded in building some sort of a time travel machine, called the Large Hadron Collider. This mechanism brings protons close to the speed of light, meaning that they get around 6,900 times slower. In this case, times becomes relative, and we can say these protons are propelled into the future, even if only for less than a second.
This is quite a huge achievement, but it’s still far away from our idea of time travel. Before we are able to transport human beings into the future, we will need plenty of resources we currently don’t have. Therefore, such a machine won’t become a reality too soon, but we never know what the future is hiding.
