I commented that it was convenient to have a Foccault’s Pendulum near my
workplace, so I could check from time to time that the earth was still
rotating. Others noted that there would be other signs of the earths lack of
rotation - the most intriguing was that the earth would explode (really! I
didn’t believe it at first, either).
I’d thought that there might be some day/night problems, weather anomalies
and so on, but discussion revealed that the earth would, in fact, explode if
it stopped rotating. I think the reason given was that gravity would stop.

Could you explane this, please?

I’m no scientist, but I’ll give it a go anyway...

As you might know, the moon stopped spinning
a long time ago (it’s always showing the same side to earth) It hasn’t
exploded, and it’s still shifting huge bodies of water (known as tides) here
on earth, proving that it still executes gravity.

I suspect that the water shifting from side to side counteracts the moon’s lack
of rotation (through the conservation of energy), thus stopping it exploding.
Where the moon may run into trouble is if we get another ice age here on earth,
and the oceans freeze.
