Everyone knows something about the concept of time travel, mostly from sci-fi novels and movies. Well, it seems that reality might not be that far behind, because scientists are already experimenting with it. In fact, a time machine already exists, but experts are now trying to make it as efficient as possible, maybe even similar to what was happening in the Back to the Future movies. Albert Einstein’s famous theory of special relativity says that depending on how fast you are moving, time becomes relative. This serves as the base for the modern concept of time travel and the research that’s been done to achieve it.
According to Ohio State University astrophysicist Paul Sutter, the theory goes that the faster you move through space, the slower you move through time. It seems that achieving time travel is not like in the movies, and not as complicated either. In fact, everything you need is a big and powerful rocket. As for time travel becoming reality, this is already happening. For example, the astronauts on the International Space Station are already moving a lot faster than the people here on Earth. This also means that they age a bit slower than people living down here.
Time travel already exists
Cosmonaut Gennady Padalka is one of the clearest examples of time travel. He came back on Earth after spending 879 days in space, back in September 2015. According to J. Richard Gott’s book called Time Travel in Einstein’s Universe, when he came back, the Earth was 1/44th of a second to the future that he expected to find. Padalka had already travelled into the future.
Meanwhile, the Large Hadron Collider is, in fact, a real and palpable time machine. Now, it is used to send protons into the future at nearly the speed of light. It is just a matter of time until humans will be sent into the future, and late physicist Stephen Hawking believed the same thing.
