The Lone Neutrino Mystery: Unexpected Origin of a High-Energy Particle

Although neutrinos are some of the most mind-boggling microscopic structures in nature, they are also some of the most abundant subatomic particles. Neutrinos are mostly known for their ability to pass right through matter in a similar way we’ve all seen ghosts that pass through objects in horror movies.

Therefore, we must not be shocked if a lonely neutrino travels from the depths of the Universe to visit us. That’s exactly what happened with such a particle that was born in a distant galaxy about 700 million years ago, according to Arstechnica.com. The lonely neutrino reached our planet’s South Pole in October last year, and scientists didn’t hesitate to notice it. A telescope from California detected evidence of a tidal disruption event (TDE) only several months earlier – a glow that was emanating from the friction of the same galaxy where the neutrino was coming from.

Did the tidal disruption event create the neutrino?

New research published in the Nature Astronomy journal proposed the hypothesis that the lone and wandering neutrino was created by the tidal disruption event itself. The TDE is located near the galaxy’s centre, and it spews out high energy subatomic particles.

Sjoert van Velzen, who’s a postdoc at New York University, declared:

The origin of cosmic high-energy neutrinos is unknown, primarily because they are notoriously hard to pin down,

He also added:

This result would be only the second time high-energy neutrinos have been traced back to their source.

There’s no wonder why Isaac Asimov spoke about neutrinos as being “ghost particles.” Each and every second, neutrinos pass right through our bodies without our knowledge nor consent. These particles are also bizarre by their lack of charge, and scientists believed for many years that they have no mass.
