Recently i have wondered about how the moon and sun affect gravity here on earth. I was wondering wether the force of gravity would change during night or day due to the position of the sun and the moon and their gravitational pulls. But just as I sat down to work this out (being the cool 16 year old I am) I also remembered that the sun and moon would also pull on the earth. so the question is would the pull the on the earth be the same as that on you and therefore cancel out any effects or do you infact become magically (or marginally) lighter at night or day due to this affect?
