But surely, given the right conditions, atomic matter must be a strong candidate. So the question is just how big these...
When a star comes to the end of one phase in its life (eg red giant -> white dwarf), or simply 'explodes', it results in the emission of a huge amount of matter (and energy, of course).
But what form does that matter take ??
If the star has been cool enough (or when the emitted matter...
