i know the moon and the earth is in a state of balance. moon's gravity affects tides on earth. but other than psychological effects to human beings and animals, i cant find any other factors, especially physical factors, that the moon affects.

what if the moon suddenly disappears?

(assume for reasons like an asteroid knocks it out of the orbit and drifts away; or we nuked it with several megatons of nuclear weapon or whatever.)

what would happen to earth

a. immediately
b. within a year
c. years after
care to venture?

as in not there anymore. gone. disappear. not visually, but physically gone. one day there, next day poof.

if this is a seriously PhD board, i doubt u guys would be here.

anyways, focus on the issues. it doesnt matter how the moon disappeared. the issue here is what happens after the sudden vanishing of the moon. just assume whatever happened to the moon did not affect the earth.

how does it affect the earth's rotation?

when u know more,u worry more(UFO,End of the World,nuke war....)
Our ancestor know nothing about this,yet they lived happily n safe until now...
No worry,be happy
