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.
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.
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.
