Gold is synthesized during the core-collapse phase of a supernova, specifically through the collision of neutron stars. This process occurs within three seconds, where the collapse of the stellar core generates a shock wave that produces heavy elements, including gold. Initially, gold exists as a gas and cools to form dust, which later coalesces into larger objects. The boiling point of gold is 2,856°C (5,173°F), beyond which it can exist as gas, even in the vacuum of outer space.
PREREQUISITESAstronomers, astrophysicists, and anyone interested in the origins of heavy elements in the universe will benefit from this discussion.
The two decide to come together, and in the wake of this event their lives are violently destroyed, spraying everybody around with radioactive remains of their marriage, that also happen to include some money - buried in heaps of molten lead and poisonous mercury.Fervent Freyja said:

During a core-collapse supernova what remains of the stellar core collapses to either a neutron star or a black hole, depending on its mass. The subatomic particles that made up the core are crushed together forming neutrons and neutrinos. The neutrinos rush out from the center of the collapsing core and push the in-falling layers of the star back out into space. This neutrino "bounce" produces a shock wave that contains enough energy to produce the heavier elements such as silver, lead, gold, platinum, and uranium. This whole process takes less than 3 seconds. Light is emitted as a result of the expanding shock wave crashing into gas and dust on its way out of the supernova. Gold starts out as a gas, and quickly cools to form dust, which then coalesces into larger objects. If you heat gold beyond its boiling point - 2,856°C (5,173°F) - you can create gold gas.tionis said:
... at one atmosphere pressure; lower pressures mean lower temperatures, and in the "vacuum" of outer space it's possible to have single atoms/ions of gold at CMB temperatures.|Glitch| said:
