- It's called a graviton.
稱為引力子
- Will be a tiny unit of gravity,the graviton.
發現微小的引力單元 也就是引子力

- by 2018 had its own ARM based server chip Graviton.

- And that's irksome because a hypothetical Boesen called a graviton could solve some major issues in physics.
而這很不爽，因為一個叫引力子的假想波生可以解決物理學中的一些重大問題。
- The renowned physicist Freeman Dyson suggested that a hypothetical detector sensitive enough to observe a single graviton would be so massive that the detector itself would collapse into a black hole.
著名物理學家弗里曼-戴森提出，一個假設的探測器足夠敏感，可以觀測到單個引力子，它的體積會非常大，以至於探測器本身會坍塌成黑洞。

- 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.
問題在於，在電磁學中，對稱性的存在預示了一個非常明顯的現象，即光子的品質為零。這是一個無品質粒子。作為一種無品質粒子，意味著與該粒子相關的力可以在整個空間中延伸很遠。事實上，我們所知道的兩種無品質粒子是電磁學中的光子和萬有引力中的引力子，這兩種粒子都會產生遠距離的力。但核力不是遠距離的。它們被限制在原子核內部非常短的距離內，所以其他人說，這不可能是類似電磁學的量規原理，一定是不同的東西。事實證明，弱核力和強核力的確都是由規整對稱性引起的，就像電磁學一樣，但大自然以非常巧妙的方式將它們隱藏了起來。我喜歡說這
