Recently, Chinese scientists have made a breakthrough in the search for antimatter. Researchers from the Institute of Modern Physics of the Chinese Academy of Sciences and other institutions have discovered a substance calledAntimatter of "Anti-superhydrogen-4",This isThe heaviest antimatter hypernucleus ever observed experimentallyThis discovery made peopleAnother important step forward in the exploration of antimatter and antimatter symmetryThis will also help humans uncover the mystery of the Big Bang in the early universe. The relevant research results were published in the international academic journal Nature on August 21, Beijing time.

What are matter and antimatter? Current physics knowledge believes that matter and antimatter should exist at the beginning of the universe, and both exist in equal amounts. But it is difficult to find antimatter in the universe today, so many people are curious, where did the antimatter go? The answer given by scientists is that antimatter can easily annihilate with the surrounding matter, that is, it disappears as soon as it exists. If the amount of matter and antimatter in the universe remains equal, they will eventually be completely annihilated and turned into a ball of light. Fortunately, under the action of a certain physical mechanism, there is an imbalance in the amount of matter and antimatter. A part of the excess matter was not annihilated by antimatter, which constitutes today's world and is also the basis for the birth and existence of human civilization. In this case, scientists are very much looking forward to finding antimatter in some way, so as to uncover a series of mysteries such as the beginning of the universe in the laboratory.
