Some mysterious things emerge from the frozen ground of Antarctica and may destroy physics as we know it.
The physicist doesn’t know what it is. But they do know that it is a cosmic ray, a high-energy particle that can travel through space and return to Earth. But the particles known to physicists, the collection of particles that make up what scientists call the Standard Model of Particle Physics (SM), should not be able to do this. Of course, there are some low-energy neutrinos that can penetrate miles of rock without being affected. But high-energy neutrinos and other high-energy particles have “large cross sections.” This means that they almost always collide with something shortly after entering the ground and never come out the other side. However, since March 2016, researchers have been puzzled by two events in Antarctica. Cosmic rays erupted from Earth and were detected by NASA’s Antarctic Pulse Transient Antenna (ANITA), a kind of balloon A antenna that floats over the southern continent.
ANITA aims to capture cosmic rays from outer space, so when the instrument detects particles that appear to explode from the earth rather than shrink in space, the community of high-energy neutrinos buzzes with Rattle excitement. Because cosmic rays shouldn’t do that, scientists are beginning to wonder if these mysterious rays are made of particles that have never been seen before.

space station Since then, physicists have proposed various explanations for these “upward” cosmic rays, from sterile neutrinos (in Chinese). Trines rarely hit matter) up to “atypical distribution of dark matter within the earth”, referring to the mysterious form of matter that does not interact with light [18 major unsolved mysteries in physics]
All explanations are very interesting , And showed that ANITA may have detected a particle included in the model standard. But none of the explanations can ultimately prove that something more ordinary cannot cause a signal in ANITA.
A new document uploaded to the arXiv prepress server today (Sep 26) changed this. Among them, a group of astrophysicists from Pennsylvania State University showed that there are more ascending energetic particles than were detected during the two ANITA events. They write that IceCube (another largest neutrino observatory in Antarctica) has detected similar particles three times, although no one has connected these events to the ANITA mystery. Furthermore, by combining the IceCube and ANITA data sets, researchers at Pennsylvania State University have calculated that regardless of which particle emerges from the ground, the probability of it becoming part of the Standard Model is much less than 1. at 3.5 million. (In terms of technology and statistics, your results have 5.8 and 7.0 sigma confidence levels, depending on the calculation results you are viewing.)
Breaking Physics
Lead author of the new article Derek Fox said it first came up in 2018 in the ANITA Incident in May 2005, in a previous article trying to explain them.
“I thought, ‘This model doesn’t make a lot of sense,'” Fox told Live Science, “but [ANITA] turned out to be very interesting, so I started to check it out. I started talking to my office neighbor Steinn Sigurdsson [the second author of the article, who is also at Pennsylvania State University] about whether we can find a more reasonable explanation than the articles published so far.
Fox, Sigurdsson and their colleagues began looking for similar events in the data collected by other detectors. When they found possible upward events in the IceCube data, he said that he realized that he could have found some real changes in physics. [5 Mysterious Particles Lurking Underground] Experiment

“This is what really made me move forward, and take the ANITA incident with a very serious attitude,” he said, then added, “This is their life. Physicist. Break the model, establish new limits [on reality], and understand what we don’t know about the universe.”
As Live Science previously reported, experimental high-energy particle physics has stagnated for the past few years. When the 17-mile (27-kilometer), $10 billion Large Hadron Collider (LHC) was completed on the French-Swiss border in 2009, scientists thought it would unlock the mystery of supersymmetry. Scientists believe that supersymmetry is A mysterious theoretical particle suspected may exist. Outside of current physics, but it has never been detected. According to supersymmetry, every existing particle in the standard model has a supersymmetry partner. Researchers suspect that the existence of these partners is due to the known particle masses being misaligned and asymmetric to each other.
“Although SM can explain a large number of phenomena well, it still has many shortcomings,” said Seyda Ipek, a particle physicist at the University of California, Irvine, who was not involved in the current research.
