We just watched the Futurama episodes where alien cats stopped the Earth’s rotation, and they fixed it by making it rotate in the opposite direction.
Lois Lane would be resurrected and unburied by rocks if there had been an earthquake caused by a nuclear strike shortly before this happened.
We should assume that has happened.
Didn’t they make a documentary about this?
We all die, a lot us rapidly when the water keeps moving across the rock that just stopped and super tsunamis a good portion of the planet. The rest of us die slowly as the weather patterns are ruined for likely decades or centuries and we starve due to crop failures and the fact that the worldwide logistics we depend on is forever gone
I don’t know. Couldn’t it be gradual enough that we barely noticed the acceleration changes but still only take a couple of hours?
Randall Munroe made an xkcd about this. It’s not on his website unfortunately, but someone else uploaded it. I would recommend using a adblocker though.
But OP asked a different question. Not what happens when earth stops spinning but what happens when earth spins in the other direction.
The answer is largely the same if you make the same assumptions though, just roughly twice as bad because not only does the earth stop and everything not attached goes yeet, but everything attached starts moving just as fast as you in the opposite direction
Time goes backwards and I get to eat that cake I had last week?
A week is too long. Before you can eat it again backwards, you have to push it up your rear end…
Good news, everyone!
You had it last week it has to back in first
*shlorp*
Imagine reversing every bathroom break you’ve had in your life. “Hang on I gotta run to the restroom and conjure up a poop from the sewer”
Imagine people casually walking into the restroom and then coming back out and running away in a sweaty panic with diarrhea
Lois Lane would come back to life
Astrology teachings would have to do a full 360 degree turn to retain their accuracy.
Full 360 degree turn, eh?
:)
This comment gave me the motivation to turn my life around and do a full 360.
Sundials will be useless
Nah just send each to the other hemisphere.
Wait, I need an animated diagram
I can’t say this with any authority, but I think the biggest effect would be in weather patterns and the subsequent downstream effects of having different weather.
Nah, the biggest effect would be in every single thing at or above ground level being instantly shot eastward at somewhere between 0 and 1,000 miles per hour. After that the weather is pretty much irrelevant because anything that would experience it would be dead as shit.
Only if the rotation would stop immediately. A slow deceleration would not let that happen
I mean, people have survived all kinds of crazy shit, I’m confident that many would actually somehow survive.
Can I volunteer to be one of the things shot eastward at 0 mph?
The earth’s magnetic field would probably ‘follow’ and change it’s direction. But only a while later and very slowly. During the change, that would leave us without a magnetic field for some time. Then we have lots of cosmic rays hitting us, damaging some of the life on eath.
The toilet will flush the opposite way

It spins the other way.
Only a change in rotational speed would be bad. If earth were to rotate in the opposite direction since the beginning it would behave just like today.
That was my thought. The only major change I could see happening (besides the cataclysmic events from the change) is the direction of sunrise/sunset.
Exactly
Proof: define Antarctica as North. Now earth is rotating in the other direction.
I don’t really know but based on the answers here this is the disaster movie I need next
Need more info. Does the earth immediately stop spinning and start spinning in the opposite direction? Or does it gradually stop over an arbitrary amount of time and reverse directions? Haven’t seen the episode…
In the episode it had stopped for a while first, then they slowly spun it up.
Let’s entertain a thought experiment here.
The earth suddenly reverses rotation. Basically the entire surface of the earth is subjected to a massive reversal of force. The tidal waves would wash over most of the land we have everything would be wrenched asunder the crust of the earth would tear spilling magma into barren oceans.
The earth slows down stops then starts spinning again. Gravity would become weaker and weaker one side of the earth would be perpetual night and the other side perpetual day the atmosphere would dissipate into space along with anything loose on the surface which includes all the water we have all life would perish. Slowly, as the earth starts to spin again gravity might pull some of its materials back down but hardly enough to make a difference. The earth would be a barren wasteland.
The earth suddenly stops spinning. Everything on the surface of the earth including all its water and the atmosphere would be violently flung into outer space. All life would perish as our human corpses hurled at extreme speeds through our solar system.

Why would gravity become weaker and things float off into space? Gravity has nothing to do with the earth spinning. It’s a property of mass. The mass of the earth wouldn’t change because it stops spinning.
So you’re absolutely right. Full disclosure I have been sick the last week and on prescribed narcotic medication and in my opioid muddled mind a massive body needed to rotate to produce gravity.
It sounded cool in my head.
Nothing. Only have to swap N-S poles and East becomes West. 💈 🧭
Everybody would fall over.
If it happened suddenly, there would be massive tidal waves on western coasts.
The sun would rise in the west and set in the east. Timezones would be backward. People in different areas would have oddly desynchronized sunlight exposure relative to the time on their clocks. For example, if this happened at sunset for you, the sun would rise first from the east and set in the west, then rise again from the west and set in the east. You’d be halfway through a double day at the moment of switching. Other people would have a double night.
Nothing if it does a flip first.
Would somebody smarter than me take these seeds of an idea and expand on how the physical forces would affect the composition of the Earth? My intuition tells me the shear forces would obliterate the planet, but I’m not sure.
Because of the nature of a sphere, the material rotating at the poles is effectively not moving at all. Whereas the material moving at the equator is moving at the maximum rotational speed of the Earth.
Likewise the core of the Earth is effectively still and the speed of each strata moves correspondingly faster as you get closer to the surface.
All the wind on the planet now blows to the opposite direction

Regardless of how fast or slow you reversed the direction. Pretty much every weather pattern and ocean current on the surface of the planet would be thrown into a massive calamity. The Corolis effect and momentum imparted to surface fluids around our rotating ball is a huge, huge deal with weather flow. It directs how storm systems form and track and which typical track they take as the rotation of the earth is constantly deflecting them. There would be huge, unending storm systems as existing patterns now crashed into new ones, with storm fronts spanning entire continents. Agricultural breadbaskets would be either destroyed or stranded in drought.
