Back in , moviegoers were treated to an amazing sight: Superman reversing the spin of the Earth, turning back time in the process and saving his beloved Lois. Preposterous, of course, but what if something did change the Earth's rotation? What if the rotation stopped completely? Let's get our admittedly far-fetched assumptions on the table. First, let's assume the Earth stopped spinning gradually, as a sudden deceleration would mean disaster.

What would happen if the Earth abruptly stopped spinning for 42 seconds? If the earth stops spinning suddenly, the atmosphere will continue to spin. This means very high speed winds, i. The winds will also cause erosion to the earth's crust. A sudden stop of the spin will have a similar effect to when you press brakes on a moving car.

The good news is that if the Earth's rotation stopped, we wouldn't fall off. With water pushed to the poles, we could walk on land around the entire equator, but it would be a very inhospitable place, as Dr Karl Kruszelnicki explains.

If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes. But not to worry: Such an event would require the same amount of energy stored in the momentum of everything on our rotating planet, says Jim Zimbelman, a geologist in the Center for Earth and Planetary Studies at the National Air and Space Museum, and no physical mechanism on earth can supply that. Q: Were there ever monkeys native to North America?

The probability for such an event is practically zero in the next few billion years. If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth's original mile per hour rotation speed at the equator. All of the land masses would be scoured clean of anything not attached to bedrock. This means rocks, topsoil, trees, buildings, your pet dog, and so on, would be swept away into the atmosphere. If the process happened gradually over billions of years, the situation would be very different, and it is this possibility which is the most likely as the constant torquing of the Sun and Moon upon the Earth finally reaches it's conclusion. If the rotation period slowed to 1 rotation every days a condition called 'sun synchronous', every spot in the Earth would have permanent daytime or nighttime all year long.

Hypothetical questions are always really fun in science because they make us think about what we know in a different light, which can make us better understand the huge scale of our planet. So let's stop the Earth from spinning and see what happens. At the equator, it's like being in a car that was moving at 1, kilometers 1, miles per hour and hitting the breaks. The good news is that this might not kill you. But everything else will. The Earth might be still but everything else will continue to move at exactly the same speed the Earth was spinning before. This includes the atmosphere and all of the oceans.



The thought experiment: What would happen if the Earth stopped spinning?

If Earth stopped rotating and fell to a standstill, humanity would be in trouble. If the planet stopped suddenly, everything on the surface would be destroyed, as the atmosphere, oceans and anything not nailed down kept spinning.,
