It's called a graviton.
Will be a tiny unit of gravity,the graviton.
The problem was in electromagnetism the existence of that symmetry predicts something very noticeable namely the photon has zero mass. It's a massless particle. Being a massless particle means the force associated with that particle extends very far throughout space and indeed the two massless particles we know about are the photon of electromagnetism and the graviton of gravity both of which give rise to long range forces. But the nuclear forces are not long range. They're confined to very short distances inside the nucleus so other people said well it can't be a similar gauge principle like electromagnetism has to be something different. It turns out that indeed both the weak nuclear force and the strong nuclear force are due to gauge symmetries much like electromagnetism but nature hides them from us in very clever ways. And I like to say this is because the universe loves us and the reason why the universe loves us is because it uses every possible trick in its book to construct the standard model of particle physics to make it the most rewarding it can be when physicists figure it out and when graduate students have to solve those problems. So basically if you want these massless particles to not give rise to long range forces there's two different ways to do it.
"I detected graviton vibrations in the hull."
"Graviton buildup could be a precursor to mass expansion."
Now appeared to be a graviton,
by 2018 had its own ARM based server chip Graviton.
And indeed, the two massless particles we know about are the photon of electromagnetism and the graviton of gravity, both of which give rise to long range forces.
