The Largest Star in the Universe – Size Comparison
There are a few things I'd like to see solved, one is that after the big bang when energy stopped becoming matter and matter becoming energy the universe would have been rather small and extremely dense. That kind of suggests that the first stars would have been extremely large and fast-burning since lots of small stars would be so close together that they'd easily converge into very large stars. Such very large stars would burn very quickly and fill the universe with heavy elements rather quickly, is my guess.
Another guess I have is that inside supernova, where the iron core has collapsed, I think that matter coverts to energy and back to matter would mean that large amount of anti-matter would be created in the process and when it annihilates that provides the energy that blows the star apart. Anyway, I will keep watch to see what new lectures/videos appear that take on these questions.
