The NEW SCIENCE of Moon Formation
PBS Space Time・16 minutes read
Einstein questioned the moon's reality based on quantum mechanics, but scientific data supports its formation through a giant impact hypothesis, leading to the moon's unique properties and history of volcanic activity. Liquid metallic hydrogen and supercritical fluids are unique states of matter with specific properties, offering potential applications as solvents and heat carriers.
Insights
- Einstein's skepticism about the moon's reality based on quantum mechanics challenges traditional views of celestial bodies.
- The giant impact hypothesis, proposing a collision between Earth and a Mars-sized body, provides a compelling explanation for the moon's formation, supported by high-resolution simulations showing a temporary presence of two moons post-impact.
