What if the World turned to Gold? - The Gold Apocalypse

Summary by Krater

An exploration of the scientific scenario of what would happen if Earth turned into gold, examining the physics and consequences of gold's atomic structure, density, and gravitational changes.

Answers: What would happen if Earth turned into gold?

• Gold atom structure
• Density of gold vs Earth
• Planetary collapse physics
• Impact of increased gravity on Earth
• Melting point of a gold planet

What it concludes

• Replacing Earth's atoms with gold atoms would cause the gold duck to explode due to violent atom repulsion.
• Rearranging Earth's existing matter into gold would create a spongy planet with microscopic gaps that contracts to two-thirds of its radius.
• Replacing Earth with solid gold of the same volume would make the Earth three and a half times more massive and increase surface gravity threefold.
• A gold Earth's core would reach 1,000,000 degrees Celsius and its surface would vaporize into a plasma cloud before cooling into a shiny golden ball.
