It is estimated that about 10 billion neutrinos pass through your body every second. That's why scientists want to study neutrinos.
Because neutrinos do not interact with normal matter, they do not affect us. If you were to stand next to a reactor for several hours, you would still be safe.
However, neutrinos do impact us in a roundabout way. For example, neutrinos could explain some of the mysteries surrounding dark matter. Dark matter makes up 85% of all matter in the universe. Scientists theorized that it exists because they cannot see it directly.
In addition, neutrinos may have played a role in the evolution of the early universe. The Big Bang Theory states that the universe began as a single point known as the singularity. This event occurred 13.8 billion years ago.
The Big Bang Theory also says that the universe expanded from this point. As time passed, the universe grew larger. Eventually, gravity became strong enough to stop its expansion. This led to the formation of galaxies.
Scientists believe that neutrinos played a key role in this process. They say that neutrinos interacted with other particles during the early stages of the universe. These interactions caused the particles to clump together, forming stars and planets.
Neutrinos have been used to help solve many scientific puzzles. However, there is still much work to be done before we fully understand how neutrinos behave in space.
