Are Black Holes Hollow?

G'day

 

For a gravitational field to form and create an event horizon or even a trapping horizon the density would need to be greter than the density of the centre of an atom.

 

Now I'm talking about the actual compact matter only.

TWO NEW ONES

 

I recently came across this: The mass/energy of the original colapsing star is entirely transformed into gravitational energy [whatever that is]. Further, matter at the event horizon forms a sort of massive shell as the speed of light is approached, and never gets close to the center. Well. THIS Black Hole would certainly be hollow :)

 

Further, I seem to recall a second verssion where the original star mass collapses into a solid plank mass. This second vesrsion retains the outer shell discused in the first version. PS: I don't know where the hell I saw these things, otherwise I would provide links; they are not of my own construction, however.
