The linked site describes an experiment supporting quantization of gravity. Gravity acts in discrete steps?

Very interesting. I wonder if the wavelength is the Compton wavelength of the neutron? I think gravity is a push. New book coming out in a month or 2 on "Pushing Gravity" explains why.

If Einstein is right, then it's neither a push nor a pull. Right?

Gravity is acting classically, the only quantum effect is in re the behavior of quantum particles (neutrons) in a classical potential. So its definately not quantum gravity and all the baggage associated with that term.
