A team of physicists from Sofia University in Bulgaria say that wormholes, which are hypothetical tunnels linking one part of the universe to another, might be hiding in plain sight — in the form of black holes, New Scientist reports.
Black holes have long puzzled scientists, gobbling up matter and never letting it escape.
But where does all of this matter go? Physicists have long toyed with the idea that these black holes could be leading to "white holes," or wells that spew out streams of particles and radiation.
These two ends could together form a wormhole, or an Einstein-Rosen bridge to be specific, which some physicists believe could stretch any amount of time and space, a tantalizing theory that could rewrite the laws of spacetime as we understand them today.
Now, the researchers suggest that the "throat" of a wormhole could look very similar to previously discovered black holes, like the monster Sagittarius A* which is believed to be lurking at the center of our galaxy.
"Ten years ago, wormholes were completely in the area of science fiction," team lead Petya Nedkova at Sofia University told New Scientist. "Now, they are coming forward to the frontiers of science and people are actively searching."
[...] The only way to really tell for sure would be to scan these celestial oddities with an even higher-resolution telescope.
The other option, of course, would be to risk it all by flinging yourself into a black hole.
"If you were nearby, you would find out too late," Nedkova told the publication. "You'll get to know the difference when you either die or you pass through."
