Researchers Bombard Anti-hydrogen Atoms With Laser Pointers
According to media reports. The extreme imbalance between matter and antimatter is one of the most confusing puzzles in the universe. They were all produced during the Big Bang, but now it is an ordinary matter that dominates. The reason for this is unknown. To solve this puzzle, the most obvious way is to observe antimatter itself. If scientists can find a certain difference in the behavior of antimatter, they may be able to find a clue to explain this extreme imbalance. To this end, a laser pointer research team decided to test whether hydrogen atoms and antihydrogen atoms have the same spectrum-absorbing and releasing the light of the same wavelength. They performed laser spectroscopy on an antihydrogen atom for the first time, but the results obtained were surprisingly similar to conventional hydrogen atoms. Artistic imagination: anti-hydrogen atom isolated. After wandering in the "trap" for a period of time, anti-hydrogen atoms will be released. Use a laser pointer for bombardment. Generate signals that can be tracked by nearby detectors.

Antimatter has the opposite charge to ordinary matter. An ordinary hydrogen atom consists of a proton (positive charge) and a much smaller electron (negative charge). The antihydrogen atom is composed of an antiproton (negative charge) and an antielectron (also called a positron, which is positively charged). When matter and antimatter collide, they will annihilate, leaving only high-energy protons, which also makes it difficult for scientists to study antimatter in the laboratory. The air, people, and experimental equipment in the laboratory are all composed of ordinary matter. As long as there are a few wandering atoms, your anti-atoms will disappear without a trace in an instant. Considering that the cost of manufacturing antimatter is extremely expensive, this situation is certainly not satisfactory. Therefore, the researchers came up with an ingenious method: to isolate the antimatter so that it cannot collide with anything else. Using the laser pointer electric field, the researchers isolated the antimatter in an instrument. The time is about 10 minutes.
