Decrypt!The explanation of the largest explosion in the universe is very reasonable

Light explosion -empty sky cosmic gamma ray violence

Light explosion -the rays behind high -energy particles will become the reserves of the earth

Gama Radiac (hereinafter referred to as: (Gama Radia) GRB) is the brightest and most energy explosion in the universe. According to the National Aeronautics and Space Agency (NASA), the GRB, which was released by a huge cosmic explosion (gamma ray), can emit a light of 1 million times brighter than the sun on the earth -and, the main, the main main, the main main, the main main, the main main, the main main, the main main, the main main, the main main, the main main, the main main, the main main, the main main, the main main, the main main, the main mainly It is a scientist who can't explain why they happen.

Part of the problem is that the known gamma storms come from very, very distant places -usually billions of light years from the earth. Sometimes, GRB's mother galaxy is so distant, so that the outbreak of light does not seem to come from anywhere, flashing from the dark and empty sky, disappearing after a few seconds. These gamma storms, which are called "empty" by some astronomers, present a mystery that lasted more than 60 years. But now, a new study published in the Journal of Nature on September 15 provides a convincing mathematical explanation for the origin of rape.

The researchers simulated the interaction between gamma rays and other powerful energy sources (such as cosmic rays). According to research, all nebula -shaped empty outbreaks may be the result of the large -quality star explosion in the distant galaxy disk.

The main author of the study, the celestial physicist at the National University of Canberra Australia, said in a statement: "We simulated the gamma ray launch of all galaxies in the universe and found that the galaxy formed by a star produced most of the galaxies produced by the star. (Empty sky) gamma rays. "

This is a map of gamma ray sky, shot by the Fermi telescope of NASA. Empty (Gama Radio) GRB appears above and below the center of the map, and the center of the map is the center of the galaxy.

Past explosion

Astronomers have two main interpretations of the mystery of empty sky gamma. One explanation is that when the gas falls into the large quality black hole in the center of all galaxies in the universe, a ray will be generated. In this case, when the gas particles are inhaled into the black hole, a small part escapes and radiates at a large jet substance near the speed of light. Scientists believe that these powerful jets may lead to gamma rays.

Another explanation points to the star explosion of the supernova. When the huge star energy was exhausted, a violent supernova broke out, and eruption particles were erupted at the speed of light. These high -energy particles are called cosmic rays, and then collide with the particles that are scattered between the stars scattered, producing gamma rays.

In the new research, researchers focus on the interaction between the universe rays and various types of interaction in the galaxy, focusing on the second interpretation. They found that the rate of gamma rays was affected by several key factors, including the size of the galaxy, the rate of star formation (which affects the rate of supernova) and the initial energy of cosmic rays generated by each supernova.

Once the team has a model, it can predict the incidence of GRB (gamma rays) of different sizes. Their model is compared with the real survey of Gamma ray radiation compiled by Fermagma Radio Space Telescope of NASA Essence Researchers have found that their computing is consistent with the results of observation, and the supernova in the star formation of the galaxy can explain most (if it is not all) Empty (Gama Radio) GRBS.

Rose said: "This is an important milestone, and finally discovered the origin of gamma rays, solved the mystery of the universe that astronomers have tried to solve since the 1960s."

Researchers added that black holes may still be the source of some gamma rays received by our satellites. But for the mysterious empty gamma rays, the barren cave is not necessary; the star explosion of the distant corner of the universe is enough to explain this phenomenon.
