Hi.

I've heard that it is impossible to "confine" a particle to a
distance
smaller than one Planck length, since that would cause it to become
a
black hole. But wait! A black hole singularity is a place of
INFINITE
density, which means it's infinitely SMALLER than a Planck length!
So
once you get it into a black hole, it is indeed "confined" to a
much
smaller region! Or is it possible that perhaps black holes are
_not_
infinitely dense, and this is just a place where current theory
fails,
and that they might in reality have only finite (but presumably,
huge)
density?

Yes, it is possible. We have no idea what happens inside a black hole
event horizon.

All we know are the following two things:
1. We know of no physical processes that will stop the gravitational
collapse inside the event horizon.
2. We know nothing about what happens at scales comparable to, or
smaller than, the Planck scale.

Any presumed contradictions about what happens *at* the singularity
are purely artifacts of extrapolation beyond what we really know.

you are clueless

Well said, John, full of physics content to mull.
How are your pretty CAD pictures coming? Been able to calculate
anything about neutrinos with them?

Is a picture of a
constant-acceleration pathway
a mathematical statement?

I am at 570 degrees of the 720 I
need to show a neutrino.

It is pretty.

The event horizon of a black
hole is that point in the vortex
where you are close enough to the
center that the spin turns photons
around fast enough that they can't
get back out. Inside of this point no
negative charges can remain associated
with their positive counterparts. Virtual particles
are ripped apart and ejected, as are also
real particles.

We are in one always self-similar to any other one. Our local universe. We
can't see out of it to any larger universe. And it appears terrifically
curved in on itself. The apparent straight line of it from there to here has
one very odd bulge of leveling off in the apparent acceleration in the
general proximity of the very middle of the apparent straight line. And the
arrow of time of it always [apparently] points this way singularly from
every direction, as if into a singularity right here, right now, without any
deviation. The arrow head tips right here, right now, wherever that is in
the local universe, or rather singularly tips at the point of the Planck
horizon (the smallest horizon, relatively speaking), or just short of it in
view, deepest within right here, right now (wherever that is). Problem is,
per curvature, so does the tail end of the arrow. That straight line to the
local universe with that bulge in the general proximity of the center of
that straight line (rather those straight lines going away) is the most
deceptive thing in all the local universe. A straight line complete
curvature back AB, BA (to the Planck horizon (the largest horizon,
relatively speaking)), or rather just short of it in view). Nothing like be
able to see almost all the way to the same most distant singular constant of
horizon from both sides of it at once (down and in to it) (up and out to
it).

We most certainly do know what conditions are like within the well of a
blackhole . . . rather within the [event horizon] of one since the Planck
horizon is always its singularity. It's where we live. It's our [local]
universe.
