Maybe someone should present this at a meeting.
No event horizon, but highly compressed - light can still escape. This
also solves the problem of an infinity small singularity that classical General Relativity predicts. I have always thought that quantum effects would prevent such a condition.

Very interesting, Don. Would one have something like an event horizon where time slows down?

The source is Scientific American, "Black Stars Not Holes", October 2009. See below quote from the issue:
"Thus, experience tells us that matter following the laws of quantum mechanics always seems to find new ways of delaying gravitational collapse. Although any of these roadblocks may be overcome (a typical stable configuration can always be made unstable by adding enough matter), each process that delays collapse provides additional time for the quantum vacuum's negative RSET to pile up and become significant. This RSET could take over the task of counterbalancing the gravitational pull, and because its repulsion may increase without limit, it can stop the matter's collapse to a black hole forever.
Black Stars
The resulting bodies would be the new kind of object we have named black stars. Because of their extremely small size and high density, they would share many observable properties with black holes, but conceptually they would be radically different. They would be material bodies, with a material surface and an interior filled with dense matter. They would be extremely dim because light emitted from their surface would be very redshifted-the light wave greatly stretched-in traveling from the intensely curved space near the black star to distant astronomers. In principle, astronomers could conduct complete astrophysical studies of black stars because no event horizon would present an obstacle."
Clear Skies,
Don
