Can’t be right, can it? It would make the Sun (over 4 billion years old) an enormous outlier.
It also would mean stars, on average, do not get very old. Over 10% of the stars that the ancient Greeks saw in the sky would have to have gone supernova since then.

- crag-jene 2y agoNot all stars can go supernova. Sol will never go supernova. Only very massive stars can—or stars that become very massive by absorbing other stars.
- btilly 2y agoBinary white dwarf systems can also go supernova, even if the combined mass is not that large as far as stars go.
