What are Neutrinos?

About Neutrinos:

• Neutrinos are tiny subatomic particles, often called 'ghost particles' because they barely interact with anything else.
• Neutrinos are, however, the most common particle in the universe. 
• Approximately 100 trillion neutrinos pass completely harmlessly through your body every second.
• Their tendency not to interact very often with other particles makes detecting neutrinos very difficult.
• Neutrinos have no charge; they are neutral, as their name implies.
• They belong to the family of particles calledleptons, which are not subject to the strong force. 
• Neutrinos don't interact at all with the strong nuclear force that binds atomic nuclei together, but they do interact with the weak forcethat controls radioactive decay. 
• Neutrinos come from all kinds of different sources and are often the product of heavy particles turning into lighter ones, a process called “decay.”
• Neutrinos are created by various radioactive decay, such as during a supernova, by cosmic rays striking atoms, etc.
