What if the Earth stopped spinning?

[Madame Adequate]

Humanity's too stubbourn to just roll over and die because of a little thing like it being totally impossible to survive.

Actually, you're probably right.... human beings find a way to do everything else. Defying the odds is what we're good at. Although we still can't build underwater cities... when THAT happens, we stand a fighting chance.

I didn't think of that at all, but you're right. Even a land-based self-contained city would stand a chance, although it'd have to have excellent heat resistence. But as with most disasters, the best thing to do is colonise more than one planet. Even if Earth gets smacked up by a meteor/volcano/giant space pie, people on Mars could survive.

There's another possibility... if the Earth stopped rotating, it could end up kind of like our moon, with the same side facing its center of rotation constantly

Nope... the reason the moon stays facing us the same way is because its "rotation" is the same rate as its "revolution". If those two are equal, you get the object always facing the same direction in relation to the other body. But a true, non-spinning, body sits with the same face in relation to the "absolute" universe. In fact, our moon actually spins *FASTER* than the earth does. It just orbits much faster around us than we do around the sun.

Just to be excessively techincal for people who are not udsana, and to bolster my own ego, that is due to a process named 'tidal locking', and it is the case for many moons in our solar system with regards to their primaries (And, interestingly enough, it's also the case between Earth and Venus. This could be simple coinkidink, though.).
