    That point in space, where the acceleration due to gravity towards the Earth, equals the acceleration due to gravity towards the Moon.

    That is, if you are a slight amount closer to the Moon, you will start to fall into it, if you were slightly closer to the Earth, you would start to fall into that.

    Yeah? Just curious...

    Lagrange Point. Do a google on 'Lagrange Point': the NASA site is particularly informative.

    RDT2 is right - there are, I beleive 7 Langrage points in our solar system, where gravitational potentials completely cancel

    whatever the point, this will never be determined any closer than the paper in front of a gravity theorist.
