The culprit can cause cosmic rays to bombard the Earth

can tear, create high-energy cosmic rays and neutrino particles rushing towards the Earth.

Daniel Biehl and colleagues at the Deutsches Elektronen-Synchrotron Research Center, Germany, propose the hypothesis that the tidal disruption event of the white dwarf is the culprit causing and bombarding the Earth every day. . The results of the study are published in Cornell University's online library, US on November 9, according to New Scientist.

"Tidal disruption occurs when a star moves too close to a black hole. The gravity of a black hole rips the star to pieces. A part of a star fragment falls into a black hole, causing a black hole to emit energy. and speeding up the particles, " said Cecilia Lunardini at Arizona University, USA.

The researchers suggest that the process of white dwarf atomic disintegration and the acceleration of the flow of matter ejected from the black hole can produce both neutrino and high-energy cosmic rays simultaneously.

"We really don't understand how cosmic rays can reach such high speeds," said Julian Krolik at John Hopkins University in the US.

Although the theory of the intermittent tidal event occurred decades ago and the scientific community discovered many potential events, only a few observations have been confirmed so far."The proportion of these events occurring in white dwarfs is unclear," Krolik said.

In the future, the team will use more sensitive and modern detectors to test new hypotheses. At that time, the tide interruption event and the starting point of the neutrino will come from an area in the sky. However, scientists also note that some other phenomena in the universe can also produce these high-energy particles.
