By looking up to the sky, you must be wondering that how big our space is. Well, no one knows it. What if you get a chance to travel in space to the most distant regions of the universe? Most of you would say yes. Right? You will be surprised to know that the scientists have finally found a vehicle to travel to most distant regions of the universe. Yes, you read it right. According to a report of express.co.uk, a recent study says that a Wormhole can allow space travel to the most distant regions of the universe in an instant.
In the paper, entitled 'Traversable wormholes in four dimensions', Princeton Physicists Juan Maldacena, Alexey Milekhin and Fedor Popov said, "We have constructed a traversable wormhole solution in four dimensions."
"This would be achieved by placing a large magnetic charge close to extremal black holes,"Â they said. Further the physicists explained that rotating the black holes was important, "so that they can be kept apart, at least for a while until the electromagnetic radiation causes them to lose energy and eventually merge with each other.
The resulting wormhole can be viewed as an entangled state of two black holes. The Princeton Physicists further describe in the paper that how they have displayed a solution of an Einstein Maxwell theory with charged fermions.
"It is a traversable wormhole in four dimensions and with no exotic matter. It balances classical and quantum effects and it has a non-trivial spacetime topology, which is forbidden in the classical theory," the Physicists stated. However, the Princeton Physicists are uncertain what exactly happens to an object once it is pulled into a black hole.
Dr Michio Kaku, a theoretical physicist at the City College of New York, argued some of his contemporaries believe black holes act like gateways throughout the universe. Then the question is what lies on the other end of that universe? And again, we are now entering the realm of science-fiction because Einstein's equations break down the two most interesting points in space-time,"Â express.co.uk quoted Dr Michio Kaku as saying.
"First, the centre of a black hole, Einstein's equations are useless at that point. Einstein's equations do predict that black holes might be used as time machines or gateways to other universes but these equations are unreliable because the gravitational force at the centre of a black hole becomes infinite, and that's nonsense,"Â he added.
According to Dr Kaku, the answer to the question of what happens when you pass through a black hole might be hidden in the study of String Theory.
It is to be noted that String Theory proposes the universe is a bubble of sorts, in which case other bubble-like universes exist, expand and collide with one another.
Dr Kaku said, "But what about time travel? Again we have to rely on String Theory but String Theory is not advanced enough to answer that question. But if time is a river as Einstein said, then that leaves open the possibility that the river of time can have whirlpools."
In the end, the physicist asserted that on the outset the theory might seem nonsensical but it is a logical conclusion to Einstein's equations.
