There is a lot of buzz surrounding the video of an alleged time traveler who claims he’s from 2030. In the video, which was uploaded on to YouTube in November but went viral just recently, a person named Noah makes several predictions about the future, even claiming that Donald Trump will be re-elected as the President of the United States of America.

Is time travel really possible? A section of scientists believe it is and Brian Greene is one of them.

Greene, professor of physics and mathematics at Columbia University and co-founder of the World Science Festival, told Express : “Albert Einstein showed that if you go out into space and travel near the speed of light, and you turn around, and you come back, your clock will be ticking off time more slowly.

“So, when you step off it’s going to be the future on planet Earth. You will have time traveled into the future.”

Interestingly, there are quite a number of people who have claimed to have experienced a time lapse. Here are a few examples.

John Titor: 

Titor is a time traveler claiming to be from 2036. According to him he is an American soldier based in Tampa, Florida, and part of a governmental time-travel project.

The Woman in The Circus:

In 2010, Irish filmmaker George Clark noticed an old women talking into a phone in Charlie Chaplin film called The Circus, which released in 1928.
Sir Robert Victor Goddard:
In 1935, a British airman named Sir Robert Victor Goddard is said to have experienced a time slip while flying over Ireland. According to J.H. Brennan, author of Time Travel: A New Prespective, Goddard flew off from a dilapidated airfield in a rain storm, but when he returned, “The torrential rain abruptly changed to bright sunlight. When he looked down he saw the airfield had been completely renovated and was now in use. There were mechanics in blue overalls walking around and four yellow planes parked on the runway. One of these was a model which, for all his aviation experience, he completely failed to recognize.”
Four years after the event the RAF began to paint their planes yellow. 
Andrew Carlssin:
In 2003 Andrew Carlssin claimed he was a time traveler from the year 2256. He attracted media attention after he made an initial investment of $800 and in two weeks’ time increased his portfolio to over $350 million. No one could have been so lucky unless they had inside knowledge. But Carlssin claimed he was a time traveler and that’s how he knew how to capitalise on good business.
Noah:
Noah claims to be a time traveler from 2030 and according to him he traveled back to 2017 to warn humans about what future has in store for them. Check out his predictions here.
