Lets answer the question,” what is mass?” When we push something, the resistance we feel is mass.
This question is quite simple to answer than the next one, ” Where does the mass come from?”
Clearly the mass come from the constituent particles that make up the objects. Now, where the mass of constituents come from? That is the mass of sub atomic particles like electrons and Quarks. So here’s the Higgs and Boses approach, imagine a large quantity of honey, throw a pebble into the honey, due to the resistance or viscosity of honey the speed of the pebble decreases. In a very similar way there is something called Higgs field. When an electron or a quark passes through Higgs field it experiences a resistance, theoretically that is where the mass comes from.
But initially most of the scientists did not believed this. But recent experiments explains many things.
In the experiment so called Large Hadron Collider (LHC), scientists made protons to move nearly with speed of light and they made them to collide. At that instinct there is kinda Slapping or Spinking space which is filled with molasses ( viscous thing) due to the bang the molasses is giggled and in that molasses a tiny spec of Higgs particle is found.
The interesting part is unlike all the elementary particle, these Higgs Boson particles won’t spin.
The proud part is in Higgs-Boson, Boson is named after an Indian scientist so called S. N. BOSE. Peter Ware Higgs a british scientist and S. N. Bose an Indian scientist together found this particle.
