Re: Light inside a black hole?

Dear Jan Panteltje:

can light and normal matter exist in some area there?

"normal matter" requires c-moderated forces to behave like we "outside
the black hole" beings expect. Light propagates "less than 0 distance"
towards an outside observer, since the "0 distance" propagation occurs
at the event horizon. So...

Any object infalling can have non-zero "radial" extension (radial to
external observer). Any object "at rest" to the external observer can
have *at most* indeterminate size, and expected (by anyone that really
studies) to have 0 size.

Or does the black hole simply get denser when you move
towards it center, as opposed to haveing a center with a
dense shell around it (black egg)?

There is nothing we know of that would impress "outer meaning" to the
contents of a BH. What we expect, based on what we know and can model,
is that all contents end up in a singular "point", where "quantum
phenomenon" will have sway.

As a follow up question: Is what we see of the universe
perhaps the inside of a black hole?

I personally expect that the CMBR is a distorted image of the Universe
that contains the BH(s) that open into our Universe. George Dishman
has valiantly tried to dissuade me from my (wacky) opinion. It would
allow complete, fully-developed structures to exist right up to the
CMBR. It has the difficulties:
* having the amount of hydrogen >> the amount of iron,
* internal GR solutions have information from the past and future of
non-local objects available (assuming *now* for you and the remote
object starts at EH crossing),
* probably more.

Since "coordinate rotation" at the EH is only by 90 deg, then our
container Universe cannot be located at the bottom of our BHs. To
fully reverse handedness, there would need to be four or more (never
was good at more than 3D) Universe's in series, connected via BHs, to
obtain closure. This allows Dark Matter to be "+/- 90 degrees" from
normal matter, and antimatter to be in another Universe "two steps
removed".

Most likely not.

Sorry, early morning question :-)

Have some coffee. Just finished mine. ;>)
