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

What are black holes?
Black holes are extremely massive objects, with a gravitational pull so strong that not even light can escape from them, and they are thought to be incredibly scattered around the galaxy, perhaps closer than we think.
“They are just prisons that can simply hold everything,” astrophysicist and science reporter Dr. Becky Smithhurst told Newsweek.
Some black holes are believed to have existed since 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 following their death in a massive explosion known as a “supernova”.
“In the same way that there are a lot of stars hanging around a galaxy, there are a lot of black holes hanging around as well,” Smithhurst said.

Black holes are closer than we think
Black holes behave in the same way as any other massive object. “If a black hole replaces the same mass as the Sun automatically, the Earth’s orbit will not change at all,” Smithurst said.
According to Smithhurst, there may be black holes roaming around the universe, and with black holes lurking even in the outskirts of our solar system, “a lot of stars formed in groups.”
There may be, too, said Smithhurst Black hole At the edge of the solar system, like this idea that there’s another planet that we haven’t discovered yet, might graze some stuff out there in these strange orbits that we’ve seen, and haven’t found.”
This is how Neptune was discovered, which had an irregular orbit of Uranus, which prompted scientists to check, whether there was another mass in the same region of the solar system, and eventually found Neptune.
Happy #BlackHoleFriday! Astronomers had hoped to find a “medium” 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, tightly packed group of stars. For years, scientists have debated whether mid-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 following the collapse of stars. But following studying this cluster with Hubble, astronomers realized that the stars aren’t orbiting one black hole. Instead, there’s a tight concentration of stellar-mass black holes lurking in the cluster.

Black hole obscuring the alleged planet
Some people put forward the hypothesis saying that the reason the planet was not found, may be because it is a black hole, its mass is 10 times the mass of the Earth or something like that, it can be classified as one of these primordial black holes, and it might just be an object stuck at the edge of the solar system causing A little bit of chaos.”
Despite its name, black holes can be detected if you know where to look, “there might be a big halo of magnetized matter around the hole,” Smithhurst explains.
“If this happened, it would create a big blast of energy with annihilation, and that would enable us to see some gamma-ray flashes from that direction,” she says. “So it’s fun to think that the solar system might have its own little black holes.”
