A super -energy neutrino that landed in 2023 has been confirmed. But where did he come from?
On February 2023, A deep -deepest cosmic particle detector recorded the arrival of a neutrino with approximately 20 to 30 times more energy than other neutrinos previously documented. With the KM3-230213A label, these particles are calculated 220 peetaelectronVols (PEV), far more than 10 PEV from neutrino. This finding created a lot of excitement among physicists, but also raised many questions.
Neutrinos are the most abundant particles in the world with mass. They are some kind of essential particles, which means they do not break down into smaller compounds and are therefore very small and light. In fact, they are the lightest sub -atomic particles with mass. Neutrinos also do not cost (unlike electron, another type of essential particles, which are negative). As a result, only rarely neutrinos interact with other materials. Often they pass directly without changing it. In fact, since reading this article, neutrino trillion is traveling through your body through space. For this reason, neutrinos are sometimes called “ghost particles”.
For particle physicists, the diagnosis of this neutrino is unusual in only two ways: or KM3-230213A was evidence of a cosmic process, we probably never saw our understanding of neutrinos. Or that was a disappointing measurement error. The researchers quickly worked to find out that the explanations were correct.
Now there seems to be a response. A comprehensive study published in the Physical Journal of Review X compared KM3-230213A data with information databases about other ghost particles that have been identified. Scientists, by analyzing existing data, believe that this neutrino was not significant and extraordinary energy.
But where did he come from?
Just as a stone cannot describe the nature of a mountain, a neutrino 220 PEV alone is not useful in explaining the phenomenon that created it. As in this article acknowledges, with the information available, it cannot “conclude a firm conclusion whether this observation refers to a new component of ultra -high energy in the spectrum.”
But if there are other recording of similar high -energy neutrinos, this will make significant progress, pointing out that other phenomena are already there. “This can mean that we are seeing cosmic neutron for the first time, when cosmic rays interact with the cosmic microwave history, or can refer to a new type of astrophysical source,” the study says.
The neutrino 2023 energy also shows that it can be emitted by one of the powerful cosmic accelerators we are aware of in the world: a gamma or supernova ray, or perhaps a plasma-prophet-oriented jet from the vicinity of a black hole. In contrast, many of the neutrinos on the ground are atmospheric neutrinos that are produced by the influence of the cosmic beams that interfere with the atmosphere in the Earth’s atmosphere and are much less energy. They are the same particles, but their potential roots affect their energy.
Different scientific branches use and study neutrinos for various reasons. Since neutrinos travel through the world without being destroyed or absorbed, they can provide valuable information about cosmic events. Some scientists, as “Journalists of the World”, think of them from time to time traveling to the ground by data that otherwise disappear.
