Time travel is possible and has already happened
One way to achieve time travel into the future would be travelling at the speed of light in space, as first theorised by Albert Einstein.
Indeed Cosmonaut Sergei Krikalev technically lives in the future due to his extended period on the International Space Station.
After spending almost 804 days in space arrived back in Earth 0.02 seconds in the future thanks to a process known as time dilation.
Under accepted theories of time travel engineers would have to build a space ship which could travel at the speed of light (186,000 miles-per-SECOND), and head out into space.
Theoretical physicist and string theorist Brian Greene, of Columbia University, said: “You can build a spaceship, go out into space [and travel] near the speed of light, turn around and come back.
