Magnetic fields of the early universe created black holes ⚡ экспресс
How do primordial black holes come to be? Scientists have proposed a new mechanism: in the early universe, during an era of ultra-stiff expansion, tiny magnetic fields stirred up ripples in space that grew stronger, spawning seeds for future black holes. This process could explain where dark matter comes from — as if invisible pebbles were born from the sparks of a campfire. Why do magnetic fields become the builders of the invisible?
Shortly after the Big Bang, magnetic fields acted like a spoon, stirring spacetime and creating eddies. These eddies turned into clumps that collapsed into black holes — primordial, born without stars. Stephen Hawking and others considered them a possible explanation for dark matter. New work shows that such holes could have arisen due to magnetic fields during the era of rapid expansion. The eddies accumulated energy until they collapsed in on themselves. Their total mass is comparable to all dark matter. And one such hole could weigh as much as a mountain but be the size of an atom — if it passed through a planet, no one would notice.
