# Inflation of singularity at moment of evaporation?

I have had an idea kicking around in my head for some time now. It all started last summer when I was kayaking down a river and I had stopped in an eddy to relax for a moment. The rate of flow of the water was strong enough to make sizable vortices along the eddy fence around the boulder that was creating the eddy in which I was resting. These vortices reminded me of the similar way in which spacetime is curved into a singularity. Long story short; black holes have been on my mind for almost a year now. I have progressed my understanding through the formation and into the evaporation of the singularity. The fact that some matter/information is lost during the evaporation perplexes me. This does not make sense to me. My suspicion is that when the mass of the singularity reaches a point in which it no longer exceeds the Tolman-Oppenheimer-Volkoff limit the singularity becomes unstable and the remaining mass, which would have been converted to energy by the force of infinite gravity, inflates into a new dimension/universe. This is just an idea of mine. Any input and discussion would be appreciated.

The singularity problem is largely resolved by LQG. Not that it is a particular attractive, solution, but, a good starting point. The extra dimensions thing appears to be unnecessary background noise, IMO.

Chronos, how does LQG solve the singularity problem?

I do not feel that LQG correctly solves for a singularity. I have not been able to find a concrete solution that could anyway. I would like to see how it does. As far as I can tell, through quantum mechanics, it could be possible for a singularity to inflate into its own dimension. Please correct me if I am wrong.

The link above is in regards to the Poplawski. He is a cosmologist that wrote a torsion based model of a universe inside every blackhole. Although I personally do not agree with his model it may interest you.

His model has two problems I have read counter papers about.
1) it does not explain early large structure formation.
2) Does not explain the CMB homogeneous and isotropic measurements.

There are a number of approaches in LQG that are singularity free - e.g.,
A no-singularity scenario in loop quantum gravity, http://arxiv.org/abs/1206.5765

Mordred- I have seen his stuff before and I do not agree with his work either. Thank you for your reply, however.

Chronos- Thank you for the link. It looks most interesting.

Perhaps the spin of a singularity can exceed its gravimetric attraction (at the edge of rotation) making the singularity 'evaporate'? - mini black holes

Actually, an event horizon cannot spin fast enough to overcome the gravity of its singularity. It can, however, flatten out to become a Kerr-Newman black hole.

Then its Hawking Radiation?

So supposely Hawking Radiation is responsible for the evaporation in mini-blackhole.?
.
How would a Kerr-Newman black hole affect this?
