Chinese scientists have just written in a study: in October 2022, they observed an unusually strong radiation, the origin of which was 2.4 billion light-years from Earth. It turned out that matter and antimatter collided.

Chinese researchers say they have detected the biggest cosmic explosion since the Big Bang. According to scientists from the Chinese Academy of Sciences, the event occurred when matter and antimatter collided at nearly the speed of light. Both were destroyed in the collision, releasing a huge amount of energy.

the Interesting engineering He writes, A spectral line at an energy level of 37 million electron volts (MeV) has been identified in an exceptionally powerful gamma-ray burst detected in 2022—which occurred about 2 billion years ago in the constellation Sagittarius.

The most powerful and brightest explosions in the universe are called gamma-ray bursts (GRBs), which are usually caused by the massive explosions of stars. In just ten seconds, as much energy is released as our Sun produces in ten billion years.

Gamma Ray Burst Animation Overview

Gamma-ray bursts are the brightest explosions in the universe. Astronomers think they happen when the core of a massive star runs out of nuclear fuel, collapses under its own weight, and forms a black hole, as shown in this animation.

On October 9, 2022, a very powerful pulse was detected by several detectors in space, as well as those on Earth. The event was codenamed GRB 221009A. Not long after, scientists began using large telescopes to investigate what might have been the source of the gamma-ray burst. It soon became clear that the burst was 70 times brighter than the brightest GRB to date.

With the help of the James Webb Space Telescope, it was possible to prove that this was indeed the brightest gamma-ray burst to date, and its source was an exploding star located about 2.4 billion light-years from Earth.

Ah! – Gamma Burst
