Answer 1

Step-by-step explanation:

periodic table, scientists constructed Galactic chemical evolution (GCE) models for all stable elements using theoretical nucleosynthesis yields and event rates of all chemical enrichment sources. 

Their study reveals unexplained quantities of gold in the cosmos, posing an astronomical mystery.

Collisions between neutron stars — can’t explain gold’s abundance either. So, where’s the gold coming from?

Past studies were right that neutron star collisions release a shower of gold. But those studies didn’t account for the rarity of those collisions. It’s hard to precisely
