The idea dominated black holes It has been in the imagination of humans for years, as some see it as a giant vacuum cleaner terrifyingly drifting through space, ready to swallow the earth in one gulp.
But today, despite black holes’ mysterious past, we understand more about them and how they work than ever.

What are black holes?
Black holes are extremely massive objects, with such a strong gravitational pull that not even light can escape from them, and they are thought to be incredibly scattered across the galaxy, possibly closer than we think.
“They’re just prisons that can just hold everything,” astrophysicist and science journalist Dr. Becky Smithhurst told Newsweek.
A few black holes are believed to have existed since then The birth of the universe The same, referred to as primordial black holes, while others are essentially the corpses of old stars, collapsed on themselves after their death in a massive explosion known as a “supernova”.
“In the same way that there are many stars around a galaxy, there are also a lot of black holes around,” Smithhurst said.

Black holes are closer than we think
Black holes behave the same way as any other massive object: “If a black hole automatically replaces the same mass as the Sun, the Earth’s orbit won’t change at all,” Smithurst said.
According to Smithhurst, there may be black holes roaming the universe and with black holes lurking even on the periphery of our solar system, “many stars have formed in clusters.”
There might be too, Smithhurst said Black hole On the fringes of the solar system, like this idea that there is another planet that we haven’t discovered yet, it could touch some things out there in these strange orbits that we have seen and have not found. “
This is how Neptune was discovered, which had an irregular orbit of Uranus, which prompted scientists to check if there was another mass in the same region of the solar system, and eventually they found Neptune.
Happy #BlackHoleFriday! Astronomers hoped to find an “average” black hole in this star cluster, but instead found evidence of a concentration of small black holes, as depicted in this artist’s impression. This is a globular cluster, which is a dense and dense group of stars. For years, scientists have debated whether medium-sized black holes might exist in these clusters. Intermediate-mass black holes are the long-sought missing link between supermassive black holes and stellar-mass black holes, which form after star collapse. But after studying this cluster with Hubble, astronomers realized that stars are not orbiting a black hole. Instead, there is a narrow concentration of stellar-mass black holes lurking in the cluster.

Black hole that obscures the supposed planet
Some people have advanced the hypothesis by saying that the reason why the planet was not found, could be because it is a black hole, its mass is 10 times the mass of the Earth or something, it can be classified as one of these. primeval black holes, and it could just be an object stuck at the edge of the solar system causing some chaos. “
Despite the name, black holes can be detected if you know where to look, “there could be a large halo of magnetized matter around the hole,” says Smithhurst.
“If that happened, it would create a big blast of energy with annihilation, and that would allow us to see some gamma-ray bursts from that direction,” he says. “So it’s funny to think that the solar system may have its own little black holes.”
