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.

interesting. i didnt know earth's tilt is held by the moon. i'll read up more on that.

interesting. coz Islamic calendar is based on the lunar cycle. no moon means no way to really determine how long each month is, meaning no more hari raya .

how does it affect the earth's rotation?

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.

it doesnt matter. several spams here had made me thinking . sometimes something stupid that comes out of one's mouth is worth gold to the other.

wait. according to my reading, the moon was what slows the earth rotation down. the earth was rotating way too fast millions of years ago. but the interaction with the moon's gravity was what slows it down gradually until the speed we have today.

anyways, what's the impact of not having tides? does the sea current stop, ceasing the thermohaline circulation in the sea and eventually global freezing ala the day after tomorrow?

seriously, u wanna discuss?

i was thinking more along the line of teleporting the earth to the otherside of the galaxy.
