Scientists have named a new property of black holes

Scientists from the Norwegian University of Science and Technology (NTNU) have proposed a new theory about the origin of ultra-high-energy cosmic rays, which could change the modern understanding of the universe's structure. This was reported by the head of the research group, Foteini Oikonomou, in an interview with Science Daily.

"We suggest that this high-energy radiation is formed under the influence of winds emanating from supermassive black holes," noted Oikonomou.

Ultra-high-energy cosmic rays are streams of protons and atomic nuclei with energy up to 10^20 electronvolts. According to the scientist, this is a colossal value - comparable to the energy of a tennis ball traveling at a speed of 200 kilometers per hour.

For comparison, this energy is approximately a billion times higher than the energy of particles created in the Large Hadron Collider. When entering Earth's atmosphere, such rays decay, therefore they do not pose a threat to the planet's surface. However, in space, they can be dangerous for astronauts, as high-energy particles can harm human health beyond Earth's protection.
