[00:00:00]What if Earth completed one [music] full rotation in just 4 hours? We jump straight into Universe Sandbox and begin this extreme spin experiment. Step by step, we increase Earth's rotation speed to see how the planet changes. Earth would be mercilessly flung into a much flatter shape because the faster a planet spins, the stronger the centrifugal force becomes. The oceans near the equator would be pushed outward violently. The equator bulges, the poles flatten, >> [music] >> massive amounts of seawater pile up around the equator. Some equatorial countries would disappear beneath oceans thousands of meters deep. Meanwhile, near the poles, sea levels would actually fall. Huge stretches of continental shelf hidden underwater today would rise [music] back above the surface. And then there's the day-night cycle. It would become absurdly fast.

[00:00:48]Human biology evolved around a 24-hour rhythm, but now the sun rises every 2 hours. Many animals would completely lose their sense of direction. Plants would struggle to maintain photosynthesis cycles. Entire ecosystems would begin collapsing. But for humans, the problem becomes [music] even worse because you would barely have time to sleep. You finally fall [music] into deep sleep and suddenly, it's daytime again.
