 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.
