do my lab report for me - Dec 24, · This process requires a very short and intense burst of neutrons and it involves the most violent processes known in our universe: most-likely supernova-explosions or the collision of two neutron stars. Actually, as much as 95% of all gold is made in this violent process, only 5% in the slow process mentioned above. Sep 15, · MICHELLE STARR. 15 SEPTEMBER When humanity finally detected the collision between two neutron stars in , we confirmed a long-held theory - in the energetic fires of these incredible explosions, elements heavier than iron are forged.

It is one of the least reactive chemical elements and is solid under standard conditions. Gold is thought to have been produced in supernova nucleosynthesis, from the collision of neutron stars. Mar 23, · For decades, the prevailing account has been that supernova explosions make gold, along with dozens of other heavy elements on the bottom few rows of the periodic table. But as computer models of supernovas have improved, they suggest that most of these explosions do just about as well at making gold as history’s alchemists. essay questions kite runner
