Physicists have noticed cosmic rays like high-energy particles that have blasted their way to the Earth and have moved out again. The strange phenomenon is not similar to “Standard Model” of particles that physicists are familiar with making it more mysterious for scientists. Though there are particles called low-energy neutrinos that can pierce through miles of rock without breaking down, but these have cross sections. In other words, they always crash into objects after reaching Earth and are not able to come out from the other end.
But since 2016, there have been two puzzling events in Antarctica wherein cosmic rays bursting out of the Earth have been detected by NASA’s Antarctic Impulsive Transient Antenna (ANITA) – an antenna borne by a balloon that keeps drifting above the cold southern continent. This device is designed to keep a note on cosmic rays hitting Earth from outer space and the community was abuzz with excitement when it discovered that the instrument was sending out details of particles bursting out of Earth instead of the other way around. They began to wonder the composition of these mysterious beams as these particles blasting out of Earth had never been seen before.
Scientists and physicists have proposed several explanations for this phenomenon from sterile neutrinos to atypical dark matter distribution within Earth. Some others stated that ANITA might have detected some phenomenon that has not been accounted for in its model, hence the anomaly. A new paper has been uploaded by a team of astrophysicists from Penn State University, which declared that there has been more upward movement of high-energy particles that was detected by another observatory in Antarctica called IceCube. By studying the details of data from both IceCube and ANITA, the researchers concluded that the particle bursting out has very little chance of being part of Standard Model.
