There's a difference between a wave and a central field. Active
cancellation of gravitational waves might indeed be possible, but given
that we haven't even detected gravitational waves yet, we're a long way
from being able to cancel them, nor is it clear why we'd want to. To
cancel the central field of a charge, you have to introduce an opposite
charge, but there's no negative gravitational charge. Or you can cancel
the field in a small region, where it's approximately linear, by
introducing a (positive) charge on the opposite side of the region. In
other words, you can cancel the earth's gravity in a limited region by
suspending an extremely massive object above the earth. But since the only
reason to cancel the earth's gravity is to make it easier to lift massive
objects, this technique is useless.

what he apparently means ,is, if there are gravitation waves,one, may be
,can send out other sort of gravi waves.to cancel out the 1e gravi
waves,and then ,there is no more gravity and we all float,
far fetched ? O yes,very.
