What If The Earth Stopped Spinning? | Summary and Q&A

TL;DR

If the Earth suddenly stopped spinning, it would lead to catastrophic consequences such as increased weight, flinging objects eastward, massive storms, deadly radiation, tsunamis, and a loss of Earth's magnetic field.

Key Insights

• ✋ The Earth's spin gives everything on the surface a tangential velocity, causing objects to be flung eastward if it were to suddenly stop.
• ❤️‍🔥 The sudden stop would result in catastrophic storms, massive fires, erosion, and damage that would be unparalleled.
• 🌸 The loss of Earth's spin would also lead to a loss of the protective magnetic field, exposing us to deadly radiation from the Sun.
• 💯 The oceans would surge onto land in tsunamis before migrating to the poles, causing the Earth to compress into a more perfect sphere.
• 🙂 The changes in Earth's rotation are currently incredibly slight but add up over time, eventually requiring adjustments to maintain accurate timekeeping.
• ⏲️ Atomic clocks are used to keep precise time, while scientists measure Earth's changing rotation speed using distant stars and quasars.
• 🫀 Leap seconds are added periodically to align atomic time with Earth's irregular rotation.

Hey, Vsauce. Michael here. The Earth is spinning and we are spinning along with it. But what if the Earth suddenly stopped spinning? Well, first of all, you would gain weight. But that would be the least of your worries. The spin of our planet is important and literally giving you the time of your life. At the equator, the surface of Earth, and ev... Read More

Questions & Answers

Q: What would happen if the Earth suddenly stopped spinning?

If the Earth stopped spinning, everything not at the poles would be flung eastward, resulting in catastrophic storms, fires, erosion, and damage.

Q: How would the stop in Earth's rotation affect humans and airplanes?

Humans outside the poles would be flung eastward and suffer severe consequences. Airplanes might have a better chance of survival if they can navigate the storms.

Q: What would happen to astronauts aboard the International Space Station if Earth stopped spinning?

Astronauts on the ISS would fare better as they are in space and not directly impacted by the Earth's rotation. However, there would likely be no one waiting for them on the ground.

Q: How would the loss of Earth's spin affect the length of a day and radiation levels?

Days would become 365 days long instead of 24 hours, and without Earth's spinning innards, the protective magnetic field would cease to exist, exposing us to deadly ionizing radiation from the Sun.

Summary & Key Takeaways

• Earth's spin gives everything on the surface a tangential velocity, which would cause objects to be flung eastward if the Earth suddenly stopped spinning.

• The sudden stop would result in worldwide storms, massive fires, erosion, damage, and a loss of Earth's protective magnetic field.

• The oceans would surge onto land in tsunamis before migrating to the poles, causing the Earth to compress into a more perfect sphere.
