（单词翻译）

 Once the fusion1 stops, the whole thing collapses2 under its own weight to form a white dwarf3, so you got this very small blob which is incredibly dense4, it's going to be something like a million times denser5 than it started off, so dense in fact that if you had a piece the size my mobile phone, it would weigh something like ten tonnes. The core of the massive red giant collapses, leaving the white dwarf denser than anything that previously6 had been discovered, this raises another perplexing question, why doesn't gravity completely destroy them? they were such baffling objects that one British astronomer7 commented an appropriate response to the message from a white dwarf was shut up, don't talk nonsense. It took a whole new revolutionary form of physics to emerge before their secrets could be unravelled8, quantum mechanics revealed much more about the innards of atoms, enabling astronomers9 to begin to solve the mystery of the white dwarf.

In physics we got two different type of particles, some particles are very gregarious10, they like to get together, and then we got other particles like the electron which like to be different from each other, they're a little bit like people at a party who are wearing the same color dress, they don't want to be standing11 next to each other, so they are going to tend to naturally push away from each other.
