Jumping into the abyss only to wake up in a totally different region of time and space surely sounds like a sci-fi scenario, but it’s actually the definition of wormholes. However, even though physicists claim that wormholes are indeed possible in theory, their existence in the real world hasn’t been proven yet.
But thanks to new research from physicists at Sofia University (Bulgaria), we now know that wormholes might actually be represented by some black holes, according to NewScientist. Otherwise, wormholes are known to be very different from black holes. While wormholes represent shortcuts in spacetime, black holes represent extremely small and dense points of matter that possess infinite gravity. Anything that gets too close to a black hole is sunken inside, and not even light can escape.
Where does the matter engulfed by a black hole go?
One reasonable question that scientists have regarding black holes is this: since these cosmic monsters absorb all matter that gets too close, where exactly does all that matter go? If the matter gets spewed on another side of space, it becomes reasonable to believe that some black holes might actually be wormholes.
The research team developed a new computer model, discovering that radiation unleashed by the discs of matter surrounding wormholes might be somewhat identical to the one surrounding black holes.
Petya Nedkova, the team leader, explained for New Scientist:
With the current observations, you cannot distinguish a black hole or a wormhole — there may be a wormhole there, but we cannot tell the difference,
So we were looking for something else up there in the sky that could be a way to distinguish black holes from wormholes.
The research team from Bulgaria remains optimistic that future observations will shed more light on the subject.
A new paper from the journal Physical Review D brings more details about the study in question.
