n.名词 noun

Physics.
- : the theoretical quantum of gravitation, usually assumed to be an elementary particle that is its own antiparticle and that has zero rest mass and charge and a spin of two.

In the 1930s, Wolfgang Pauli and Markus Fierz proposed a graviton with mass.
When you start thinking about gravity in terms of gravitons, you find that all of these pillars actually emerge just by requiring the theory to be stable.
In fact, Parikh, Wilczek and Zahariade found that the noise increases exponentially the more the gravitons are squeezed.
They found that one quantum state in particular, called a squeezed state, produces a much more pronounced graviton noise.
Many physicists assume that gravitons exist, but few think that we will ever see them.
