It's about distorting space-time to such an extent that you can effectively travel back in time or bring a "dead" star back to life, black holes are weird. But as long as astronomers and physicists try to explain it, few people really understand how strong their strength is. A concrete example: astronomers have just observed the first instance of matter falling directly into a black hole and its speed was clocked at 30% of the speed of light. By the way, it was also not a pea-sized piece of asteroid – it was a collection of gases whose mass was about equal to that of the Earth.
Normally, the material is orbited around a black hole and revolves around it for a while before being gradually sucked into the hole itself, which looks like a glass of black. Poured water into a sewer. Even the stars are unraveled and sucked up by black holes after being twisted into strand-like tendrils in a process called "spaghettification". (Yes, really.) The fact is that the material that rotates around the black hole usually has a bit of speed to counter the gravitational pull of the hole, which prevents it from falling directly. All this material forms a disc around the black hole. (called "accretion disk"), but sometimes multiple disks can form and collide, canceling their speed and allowing the black hole to wind them up incredibly quickly – even at a sizeable fraction of the speed of light.
A team of scientists led by Professor Ken Pounds of the University of Leicester managed to spot this phenomenon by observing X-rays from the supermassive black hole at the center of the PG211 + 143 galaxy, a billion years of light. Earth. "We were able to track a mass of matter the size of the Earth for about a day because it was pulled toward the black hole, accelerating to one-third the speed of light before being swallowed by the hole, "said Pounds. According to him, the black hole has 40 million times the mass of our Sun and is "well nourished".
