Scientists find way to travel across ‘very distant points in space’ in a split second


A wormhole

In the paper, entitled Traversable wormholes in four dimensions, Princeton Physicists Juan Maldacena, Alexey Milekhin and Fedor Popov declared: “We have constructed a traversable wormhole solution in four dimensions.” The physicists state that, "this would be achieved by placing a large magnetic charge close to extremal black holes." The scientists 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 physicists describe in the paper how they have displayed a solution of an Einstein Maxwell theory with charged fermions.

The said: "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."

 A black hole

Black holes are powerful wells of gravity where absolutely nothing, including light, can escape their pull.

Scientists are, however, uncertain what exactly happens to an object once it is pulled into a black hole.

Does the intense gravity crush the object into nothingness or does a black hole spit it out in some remote part of the universe? Some scientists theorize black holes act like wormholes between two points in time and space.

If correct, such wormholes could be used to instantly travel vast distances and maybe even travel through time.

 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.

Speaking to fellow physicists on the Exploration Podcast, Dr. Kaku said: "Then the question is what lies on the other end of that universe?"

And again, we’re now entering the realm of science-fiction because Einstein’s equations break down the two most interesting points in space-time.

First, the center 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 center of a black hole becomes infinite, and that’s nonsense.

But the answer to the question of what happens when you pass through a black hole might be hidden in the study of String Theory.

According to Dr. Kaku, 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.

And if the river of time has whirlpools – these are called closed time-like loops – it allows you to leave, let’s say, your office and come back before you left.

In other words, you might be able to come back yesterday.

The physicist said on the outset the theory might seem nonsensical but it is a logical conclusion to Einstein’s equations.
