Small is out there

Small is out there and it matters.Photons take millions of years to go from the middle of a star fighting gravity all the way because these light packets have some mass. Once free from the host they travel faster with less gravity to deal with.

Neutrino cousins

Neutrino

Neutrinos are among the most abundant particles in the universe, yet they are notoriously elusive. These subatomic particles are produced by various processes, including nuclear reactions in the sun and other stars, as well as during certain types of radioactive decay. Neutrinos are electrically neutral and interact with other matter only via the weak nuclear force and gravity, making them extremely challenging to detect.

Despite being produced in vast quantities, neutrinos have a minuscule mass, if any at all, and they travel close to the speed of light. They come in three different types or “flavors”: electron neutrinos, muon neutrinos, and tau neutrinos, which can transform from one type to another as they travel through space.

Neutrinos are of great interest to astrophysicists and particle physicists, as their behavior can provide valuable insights into fundamental aspects of the universe and its energetic processes.
