I posted a thought experiment regarding gravity a few days ago and got a
response from 3 people. Only one attempted to answer it. He thought =
the
spheres would go flying off from centrifugal force. Another responded =
to
his reply but did not address the question.

That was not an idle question. As there are undoubtedly many who read =
this
newsgroup who are trying to understand the nature of gravity and =
attempting
to create antigravity devices, wouldn't it make sense to have a better
understanding of what would happen if some day one of them might get =
lucky?
If not for the possibility of having the device they worked so hard to
create take off into space in less than the blink of an eye, at least to
ensure their own safety. Or their families, or their neighborhood, or =
300
people in an airplane. Maybe even some expensive NASA hardware and
personnel.

Does anyone have the "official" theory on such, and could they share it =
with
us?

There are already some well established principles that have allowed man =

Density

Now, getting back to=20antigravity. :-)

One of those ought to work once a few things are figured=20out.
