no, actually I think the slowing is based on the space dust that the world is constantly going through, although the moon may play a factor in that also.  As for the big bang, I was making a hyperbole   I just meant as the world was in development in location in the solar system.

Ok, my information on this is a little spotey so bare with me...  I heard that the earth slows down in its rotation around its axis each year, and that this is the reason we must be constantly changing our clocks for accuracy.  My question is, that if the world is slowing down in its rotation, and has been since the big bang, A.) approximately how fast was it going originally

B.) How did this effect the early development of life on the planet.

Just wondering because it seems like if it has been slowing down each year, even if it is just a little, over a billion years that would make it rotate substantially faster.
Any information on the subject would be most appreciated.
