If you could survive a trip inside the black hole, exactly where you would be at the end of that journey?
Very likely such a journey would not be a good idea. Usually formed after the collapse of a massive star and under the influence of its own gravity, these mysterious objects from space have such strong gravitational pull that even light can not escape (after reaching a certain distance from the hole, of course). What exactly would happen to someone who “rushed” into a black hole remains unclear and subject to many scientific and not so scientific speculation, but most of them are describing the process as stretching and rolling out that much so our friend would look like a spaghetti.
Today, however, scientists from the University of Valencia, Spain, focus on some theory that black holes instead of just attracting matter “inside” to the point at infinity, known as the “singularity” could be gateways to other remote regions in space. The theory use the popular term “worm holes.”
These worm holes can be tiny – for example, smaller than an atomic nucleus – but still enough to bring up the traveler if the victim had been previously sufficiently “compressed”.
Published in the journal Classical and Quantum Gravity, the Valencian physicists propose considering the singularity as if it were an imperfection in the geometric structure of space-time. And by doing so they resolve the problem of the infinite, space-deforming gravitational pull.
“Black holes are a theoretical laboratory for trying out new ideas about gravity,” says Gonzalo Olmo, a Ramón y Cajal grant researcher at the Universitat de València (University of Valencia, UV). Alongside Diego Rubiera, from the University of Lisbon, and Antonio Sánchez, PhD student also at the UV, Olmo’s research sees him analysing black holes using theories besides general relativity (GR).
Our theory naturally resolves several problems in the interpretation of electrically-charged black holes,” Olmo explains. “In the first instance we resolve the problem of the singularity, since there is a door at the centre of the black hole, the wormhole, through which space and time can continue.”
Unfortunately in the new theory there is nothing mentioned about biological survival after a journey through such a place.
