Travel to the future is possible as physicist Brian Green sees it
Travel through time may become a reality, says Columbia University professor of physics and mathematics and co-founder of the World Science Fair Brian Green.
"It is important to recognize that there are two types of travel over time that are radically different, and travel to the future is certainly possible," says Green.
He commented that we knew this because the world Einstein showed this way a hundred years ago when he showed that if one goes into space and travels near the speed of light and turns back, his watch will travel more slowly, and so when he returns, this will be the future on Earth. Time to the Future.
The second type of travel over time is to travel to the past, which is controversial because many people doubt its potential
Einstein also pointed out that if a person travels near a strong gravity source, a neutron star or a black hole, and approaches the edge of this object, time will also slow down for the person and for any other person. When he returns to earth, for example, the future.
"The second type of travel over time is traveling to the past and it's controversial because so many people doubt it," Green said.
"The main proposal that people consider worthwhile to travel to the past uses a strange concept called wormholes.
The wormhole is something Einstein also discovered in 1935 and is like a bridge from one place to another in space, a kind of tunnel that makes you short the distance from here to here. And in a certain way will travel from moment to time to another moment in time, meaning that going in a direction will be a journey to the past, and going in another direction will be a journey to the future.
Green pointed out that worm holes do not know the extent of their existence, and it is not known if they are real whether a person can pass through them, yet it is not excluded.
