Neutrino is a particle which exist everywhere on earth in plenty, it is said that about millions of neutrinos passed us every second's. But we can't feel them, neither sea them with our naked eyes.
Neutrino is very tiny in size and it is described as weightless with no electric charge. Its size is described by giving an example of atom i.e.,
"If atom is the Solar system then neutrino is the golf ball in that Solar system."
This small little tiny Neutrino is capable of travelling through a solid matter, without reacting with anything.
Our great scientist Einstein's theory says that " The speed of the in vacuum is very high, and no other thing with mass can travel faster than light."
But the research says that there is a possibility that Neutrinos are faster than light. Thus it is not been totally accepted, as more research is needed to prove that Neutrino are faster than light.
But if this sentence is true then the world is going to turn upside down, as our many theory are depending Einstein's theory of light, and their will be a situation where we would have to tear all our textbooks and rewrite them.
Another theory says that if you travels faster than speed of the light you might end up in the future, so if this Neutrino are really faster than light than they might help us to Time travel.
So you can imagine
What next to come? if neutrino are faster than light.
