Forming a penny-sized black hole on Earth would take a huge amount of mass and a method of condensing that mass into a tiny area. Theoretically yes, but practically it would be impossible to create a penny-sized black hole here on Earth. In addition, since the penny-sized black hole on our planet would effectively double the mass of Earth, the orbits of all the planets in the entire solar system would be slightly affected. In reality things would be more complicated. Theoretically if there was no spin or outward pressure to take into consideration, Heile said, it would take about 10 to 15 minutes for the entire Earth to fall into the black hole. "This angular momentum will tend to slow down the fall into the black hole and will eventually result in something like an accretion disc around the black hole," Heile wrote. This would cause whatever is left of the Earth to essentially orbit the black hole. Secondly, he said, mass falling towards a black hole will begin spinning around the black hole at an increasingly fast rate, similar to how an ice skater spins faster when they pull in their arms. "The net effect will be that there will be a strong outward pressure on the outer layers of the Earth that will first slow down their fall and will eventually ionize and push the outer layers away from the black hole." These high temperatures will cause gamma rays, X-rays, and other radiation to heat up the other matter falling into the black hole. He wrote on Quora: "When the matter near the black hole begins to fall into the black hole, it will be compressed to a very high density that will cause it to be heated to very high temperatures. He pointed out black holes are destructive not just due to their mass but also due to the intense heat and radiation they give out, and this could cause some of the Earth to be blown into space rather than sucked into the black hole. The Earth wouldn't just collapse in, he said, because of outward pressure and the fact the planet is spinning. What Is Spaghettification? Black Hole 'Sucking In' Star Seen by ScientistsĪ penny-sized black hole would have roughly the same mass as the Earth for reasons explained later.įrank Heile, a particle physicist at the University of Stanford, has previously provided insight into what would happen if a penny-sized black hole appeared at the Earth's core.Why Mars Is Called the Red Planet and What Its Atmosphere Is Made Of.This Star Is Home to the Largest Group of Earth-sized Planets Ever Found.But when a pair of these virtual particles appear right at the event horizon, one half of the pair drops into the black hole, while the other is free to escape into the Universe. Normally these virtual particles are able to recombine and disappear in a puff of annihilation as quickly as they appear. The most common kind of particles are photons, aka light, aka heat. The idea that over vast periods of time, black holes will generate virtual particles right at the edge of their event horizons. The temperature of black holes is connected to this whole concept of Hawking Radiation. We're talking about the temperature of the black hole's event horizon, when it's not absorbing any material at all. This material piles up into an accretion disk around the black hole with such density that it acts like the core of a star, undergoing nuclear fusion.īut that's not the kind of temperature we're talking about. When they're actively feeding on stars and clouds of gas and dust. Now, supermassive black holes can shine with the energy of billions of stars, when they become quasars. There is absolutely no infrared radiation coming from a black hole. And black holes absorb all the energy falling into them.
