For humanity with our current technology, reaching places in the universe which are farther than Mars is nearly impossible. However, one physicist believes interstellar space travel is possible if rotating black holes can be manipulated.
According to University of Massachusetts Dartmouth physicists, some black holes are gentler than others, and if they are large enough and rotating, they can be used to traverse the universe, says their research published in the journal Physical Review D.
Explaining the research, team member Gaurav Khanna, a National Science Foundation-funded physicist who worked on the project, wrote for The Conversation: “One of the most cherished science fiction scenarios is using a black hole as a portal to another dimension or time or universe.
“That fantasy may be closer to reality than previously imagined.”
The physicist says that the singularity – the point where the gravitational pull becomes so so immense that not even light can escape – of a rotating black is weaker.
This would allow objects to pass through, much in the same way as in the 2014 blockbuster, Interstellar.
Mr. Khanna writes: “The reason that this is possible is that the relevant singularity inside a rotating black hole is technically ‘weak’, and thus does not damage objects that interact with it.
“Under all conditions an object falling into a rotating black hole would not experience infinitely large effects upon passage through the hole’s so-called inner horizon singularity.
“This is the singularity that an object entering a rotating black hole cannot maneuver around or avoid.

“Not only may that, under the right circumstances, these effects be negligibly small, allowing for a rather comfortable passage through the singularity.
“In fact, there may no noticeable effects on the falling object at all. This increases the feasibility of using large, rotating black holes as portals for hyperspace travel.”
