Question:
How to prove the existence of graviton, boson? What is the smallest particle found? How come a particle has no charge, no mass and no existence?



Replies:
Gravitons are still theoretical. The smallest particle with non-zero rest mass is still the electron. The neutrino is a particle with zero rest mass (maybe) and no charge: it carries only spin and momentum.
