something and nothing

As Guth said,and many others including myself agree the universe gives
life the ultimate free lunch. If that was not true we would have never
made it, Bert

Just ran onto this little nugget -

It's in reiteration to Odysseus' question where he asked,

What advantage does the 'flow' analogy
have over the 'field' model that has
served so well to describe gravity?

The animation shows the literal 'reverse starburst' flow of the spatial
medium into a mass (in this case a Schwartzchild, or non-rotating BH).
Notice the acceleration of the flow as it approaches the mass. Because
no spin component is involved, this BH is a gravitic monopole. A planet
or star is also gravitically monopolar because their rotation-rate is
too miniscule to impart any bipolarity to the flow.
But a non-rotating BH is a theoretical construct that's
extremely unlikely to exist in nature. In the real universe, any BH can
be expected to have a very high spin-rate, imparted by conserved angular
momentum of the pre-collapse parent body. So the BH may be spinning at
many thousands to millions of RPM.
In the animation, picture the BH spinning at half a
million RPM. What happens to the inflow pattern? The equator is
centifugally repellent and therefore gravitates least strongly, while
the poles gravitate most strongly. The inflow naturally favors the
poles, and takes on a 'bathtub drain' vortex as it enters each pole. The
vortices have opposite _spin direction_ going in, while the whole
ensemble rotates in a unitary direction (to see this effect, hold up a
basketball and rotate it). The BH is a _gravitic dipole_ with
clear-cut 'N' and 'S' gravitic poles, their 'sign' determined by their
spin direction.
This essential bipolarity of every (spinning) BH is
mirrored in microscale, in the bipolarity of the proton and the strong
force. That's the basis of magnetism, which occurs when sufficient
numbers of protons are aligned en masse. When they're not aligned,
there's no spin component and hence no magnetism.. and the inflow just
manifests plain old monopolar gravity.
Of course, under the CBB model, there's the grandaddy
of all BHs, the Primal Particle itself, displaying the same bipolar,
dual-hemisphered planform we see in all Its 'little fractals' throughout
nature.
