Neutrinos

The word "neutrino" has been used quite a bit in science fiction over the past few decades, if you've watched any of it. It's a well-known one, and even though most of us don't understand the science, it still sounds intriguing. Neutrinos have a much more intense existence in reality than the most of us ever understand. They are atomic-scale objects created by exploding stars and other galactic catastrophes. They move almost as quickly as light, and good luck trying to stop one because they can pass through lead just as easily as you can through an open door.

A neutrino has an incredibly low mass. If you don't already have a strong foundation in physics, the numbers used to describe it won't signify a thing. They nevertheless have a smaller mass than an electron by about 500,000 times. They do not, however, have an electrical charge like an electron. A neutrino is thus hardly anything at all because it has neither mass nor charge. They are nonetheless also everywhere. You receive around a billion of them per second from the sun. The fact that a neutrino possesses mass, however minuscule, may help to explain the universe's overall mass and the existence of matter rather than antimatter all around us.
