A wormhole can hide in the center of a black hole

Remove the singularity, and the wormhole appears in the center of the black hole, but is it passable?

Black holes and wormholes are the Grail for science fiction. Need to travel in time? No problems! Build a wormhole. Want to see another Universe? Immerse yourself in a black hole!

Although these dreams are often contrived and let's face it most likely impossible, most of them are based on the ideas of real theoretical physics. New research focuses on the nature of space-time inside a black hole. Theoretical physicists have come up with the possibility of rushing through space-time ... Although of course it would not be so comfortable.

The black hole is the gravitational extreme in the truest sense. Throw in some amount of substance, and it will be crushed, down to one atom. Nothing, not even light, can escape its gravitational trap. This space-time gradient is so powerful that it catches light and is known as the event horizon.

For the most part, we have no idea what happens beyond the event horizon; this area is closed to outside observers. But the theory says that for a black hole there must be something in the center. The center of a black hole is the place where mathematics breaks down, this is a space calculator where you can divide by zero and get infinity. This cosmic computing error is hidden in the depths of the event horizon ... A team of physicists led by Diego Rubeira-Garcia from the University of Lisbon, Portugal are trying to change our “classic” view of the black hole. What if the general theory of relativity does not work and the feature is not a feature at all? What if we replace the wormhole feature? Suddenly, instead of being the end point of the universe, black holes can become the dream of science fiction scientists: they can be space-time transportation nodes.

But, as in most cases with black holes, there is a snag.

In previous calculations, the Rubéira-Garcia team created a theoretical model of a black hole without a singularity. To their surprise, a spherical wormhole structure was formed at the site of the singularity.

Before you can understand why this is important, let's consider why this feature is so fascinating to theorists. Suppose that some object (or unfortunate astronaut) falls into a black hole. The gravitational forces there are so severe that the effect of “spaghettification” will be noticeable on the astronaut. The force of attraction will affect the astronaut's toes more than the head. The best way to imagine this is to think of an astronaut as spaghetti (hence the name of the effect).

If our stretched astronaut reaches a singularity, he will be stretched infinitely long and will be infinitely thin - a situation that does not make much sense. But swap the infinity for a wormhole of finite size, and everything becomes much more interesting. Wormholes are a mathematical consequence of Einstein’s general theory of relativity, but we still haven’t found any evidence that they actually exist. If they exist, then they are, in fact, a tube of space-time, opening the passage to another place or time in the Universe. Thus, hypothetically, an object extremely deformed by gravity can pass through the neck of a wormhole.

"Every particle of an object will be under the influence of a gravitational field," Rubéira-Garcia said in a statement. "Each particle feels a slightly different gravitational force, but the interaction between the components of the body can, nevertheless, support it."

Needless to say, this study is a theoretical calculation, since we can hardly ever find out if the wormhole is in the center of a black hole.
