Yes, it is! Scientists have been attempting to find out new ways to tour in time when you consider that decades. Earlier it seem impossible, but now not anymore. According to scientists Time Travel is now just a technical problem that we want to solve.
Here are few feasible ways to journey ahead in time,
Orbiting a Black Hole - As per Theory of Relativity we know, time slows down as we get closer to an object with high gravitational potential. Black Holes are the objects with excessive gravitational potential, so if we could go closer to a Black Hole in a space-ship & orbit around it, then for us time will run slowly as compared to the humans on Earth
But the trouble with this notion is that Black Hole's gravity is so severe that it bends the space-time cloth & if our spaceship will try to strategy a Black Hole it will possibly in no way return.
High Speed - The quicker you move, slower the clock gets. Albert Einstein explained it as Time Dilation through his Theory of Relativity. He similarly gave the Twin Paradox to assist us recognize better.
What is Twin Paradox?
Twin Paradox is a idea scan involving identical twins. One of these twins makes a trip into space in a rocket whose pace is nearer to the pace of light. After the ride when he again home, he find out that the twin who remained on Earth has aged more!
So, if we should improve a rocket that can reach the velocity closer to light, then we would be in a position to travel in time.
Now, let's speak about the Backward Time Travel - A massive neighborhood of scientists agree with that it's not possible to tour backward in time because of Grandfather Paradox.
What is Grandfather Paradox?
Suppose you traveled into the past and killed your grandfather before he met your grandmother. Now, because your grandfather never met your grandmother, your father have been never born too. And if that so, then the place did you come from?
But nowadays scientists believe that they have a answer of this paradox. Solution is that, when you go into the previous you create a new timeline & your personal timeline in which you created a time computer remains unaffected. So, if you traveled lower back & killed your grandfather then you've got surely killed him in the new timeline that you created not the original one.
Travelling ahead in time requires a widespread amount of pure energy & also the technological know-how to deal with it, unluckily we do not have any of it today. Backward time tour is nevertheless a part of theories & scientists are continuously making an attempt to discover out new methods to make it reality!
