Pursued By Low Energy Antimatter Physics Laser Pointer
If it can overturn the basic symmetry between matter and antimatter particles. The significance is not only to tell us that the standard laser pointer model is wrong. In mathematics, antimatter is equivalent to ordinary matter particles flowing in counter-time. This sounds a bit of science fiction, but the reality is much more prosaic; for a hydrogen atom, whether it is "flowing against time" is actually not much different. However, if there is such a disruptive discovery, it may indicate the possibility of reversing time, which is a question of great interest to physicists. Another motivation for this research is to understand the extreme imbalance between matter and dark matter in the universe. If the dark matter can provide a different spectrum, it implies that dark matter has different physical properties from ordinary matter. And this may provide clues for the answer to this question.

Although the experimental results did not appear in the above situation. But the research will not stop there. This is only the first time in this kind of research. In many respects, this may also be the beginning of a new era. "For a long time, this has been regarded as an achievement pursued by low-energy antimatter physics," the researcher wrote in the paper. It marked a turning point from a proof-of-principle experiment to the use of anti-atomic spectra for serious measurement and precision. CPT comparison. The experimental methods used by the researchers, including new methods to isolate more anti-atoms, will provide help for a deeper understanding of antimatter in the future, and will also have a higher degree of certainty, regardless of whether there are new things waiting to be discovered. The current laser pointer results, as well as the results of other recent studies, indicate that the verification method for the basic symmetry of antimatter is rapidly maturing. The researcher wrote in the paper.
