Question about origins of elements

[Chronos]

Doppler broadening and line blending in supernova spectra makes identification of heavy elements observationally challenging. Isolating their spectral lines from the bright glow of more abundant lighter elements is an issue.

Good clarification, Nabeshin. By the time protons froze out of the chaotic mess left over from the big bang, there was only enough time left to fuse elements up to around the atomic weight of lithium.

Thanks for the clarification, Chronos.
