Slowing of Earth's Spin

[Greg]

this may be tru. but the gravity has nothing to do with the momentum of the earth spinning. as long as THE CORE keeps spinning we will be alright. because the core spinning (keep in mind very hot metal iron and nickel mainly) spinning at 10,000 mph creates a magnetic dynamo. whis is why we have gravity

:) We have gravity because of the mass of the Earth, not the spin of it's core or magnetism. Perhaps you didn't know that Venus has practically no magnetism but it has plenty of gravity.
