What is the probability that one day the earth will be sucked into a black hole? And if that happens, how? Experts believe that the chance that the earth will ever collide with a black hole before it is swallowed by the sun – and this will happen in about five billion years – is virtually zero. “It starts with the outside. Space is called that for a reason,” says Doug Gobielle, a professor of physics at the University of Rhode Island. “The average density of light matter in the universe is about one proton per cubic meter. much higher, but still virtually absent. “Objects that we consider to be” large “and” dense “in the universe are quite rare: these are planets, stars, and their associated remnants – white dwarfs, neutron stars, and black holes,” Gobiel explained. “Although there are only countless stars in our galaxy, random encounters between them are extremely rare due to the enormous distance between objects,” said Clem University son of Jonathan Zrake (Jonathan Zrake), an associate professor of physics and astronomy. to a super-advanced civilization with virtually unlimited resources and energy, which deliberately “will launch” a black hole in the solar system, such a collision is so unlikely that it is almost li ka big to zero “, says Gobiel. “We do not usually worry about stars passing through the solar system, so this can be extrapolated to the rest of the objects in the galaxy,” he said. , the so-called Oort cloud, – this affects their gravitational effect on the solar system. “Surely the same thing will happen to black holes and other compact masses that migrate outside the solar system,” he said. “Should we be afraid of ‘near’ black holes? To influence us in any way. one of the nearest, more than 3,000 light-years. “Even if a black hole swallows its twin star, its mass will not be enough for anything other than a few bursts of radiation, as Gobiel emphasized. “At this distance from Earth, we will generally only notice it using powerful instruments. And the impact on Earth will be zero at all.” Black holes are divided into two main types: stellar and supermassive (although recent studies have shown that there is probably some middle class). The star holes are several times larger than our mass. Sun Supermassive black holes, on the other hand, can have masses ranging from a few million to billions of suns. Star mass black holes like V616 Mon are the remains of massive stars that died in catastrophic cosmic explosions – they are also called supernovae. The nearest star that could theoretically form a black hole is – this is Betelgeuse, the second brightest in the constellation Orion. According to Zreik, Betelgeuse is nearing the end of its life and is likely to produce a supernova somewhere in the next 10,000 years or so. But it is also about 500 light-years away, and even if it turns into a black hole, it will have no effect on the earth. How close should a black hole be, “Although it will be difficult to miss a supermassive black hole or even a black hole of medium mass somewhere near the solar system, it is quite possible to miss a black hole with star mass at the edge of the solar system “, says Gobiel. “But even a large black hole with star mass, say 30 solar masses, would need to be closer than Neptune (which is almost 30 times longer than Earth to the Sun) to have any gravitational effect on Earth and about Jupiter’s distance (about five times longer than from the earth to the sun) to pull the earth with a force roughly equal to the gravity of the sun, “he said. not like that. “In general, black holes absorb matter terribly poorly,” he said. “The answer to the question why black holes have not yet cooled the universe is that in most cases they are extremely inefficient and grow poorly.” What if the earth is sucked into a black hole? If a black hole somehow gets close to the earth (for example, closer than the moon’s orbit) and will move slowly enough, then our planet will probably be torn apart by incredible gravity. “The earth will lose its atmosphere and its oceans, and molten metal will flow out of the earth’s mantle into space,” Zreik said. Earth debris will fall into orbit around the black hole and evaporate into an ionized gas consisting of atoms or molecules that have lost an electron or, conversely, gained another. According to Zreik, the gas forms a ring of material around the black hole, the so-called accretion disk, and most of it will be absorbed within a few hours or days. “The released energy will drive powerful currents of plasma into space – one of matter “Astronomers from nearby planets will probably notice an eruption of radiation,” he said. But the chance that this scenario will come true is astronomically small. Something more likely, but still unlikely, is the scenario where a black hole comes close enough to somehow affect the earth, but not enough to swallow our planet. The biggest danger, at least for life on the planet, is the case where a black hole disrupts the Earth’s orbit so much that the climate changes or a huge amount of debris from solar systems (asteroids, comets and satellites) with a high risk of collision, explains Zreik. “Life on earth will surely survive, but humanity and most multicellular species on earth will hardly survive,” Gobiel concluded.
