Questions about neutrino

Neutrinos

1. What is neutrino? Where can we find neutrino?
Neutrinos are elementary particles that often travel close to the speed of light, are electrically neutral, and are able to pass through ordinary matter almost undisturbed and are thus extremely difficult to detect.
Neutrinos are created as a result of certain types of radioactive decay or nuclear reactions such as those that take place in the Sun, in nuclear reactors, or when cosmic rays hit atoms. Neutrinos are everywhere

2. What is the size of neutrino?
Neutrinos have a very tiny, but nonzero mass between 0.2 eV and 2 eV.

3. Is there any electric charge in neutrino?
No there is no electric charge in neutrino.

4. What is the shape of neutrino?
The weakly interacting nature of neutrinos makes them very difficult to
detect, and therefore measure or see. Its existence is implied by the observed phenomenon of Neutrino oscillation.We can only know its mass and not its shape.

5. Give some special features of neutrino.
They
are not affected by the electromagnetic forces which act on electrons.Huge numbers of neutrinos constantly pass right through the earth and off into distant
space.Most of the neutrinos in
the universe are believed to have been formed billions of years ago, during the Big Bang. It is believed that the neutrinos coming from the Big Bang are almost stationary and that
there are 10,000,000 such neutrinos in every cubic foot of space throughout the universe,The more active neutrinos are products of the nuclear reactions that fuel
stars and high energy cosmic events such as the explosions of dying stars.
