What would its properties be? It would have to be where part of the universe is cut off from the rest of the originating universe(s) by some process and then continues on with its own existence independently leaving only a shadow of its creation. Ideally it should also be seeded in some way with elements of the originating universe.
The big question is how can such a small object lead to a big universe?. The simple answer is that the process of collapse to a singularity under an inverse square law not only results in an infinite energy density it also releases an infinite quantity of energy!
This is simply provable by considering the energy released by a thin massive spherical shell of matter collapsing under the gravity of the mass inside the shell that is also collapsing towards a theoretical singularity.
Thanks SS, in over 100 P S books I have yet to find an explanation that comes near yours.
Thank you all for your replies now to get down to the answers which I will take in chronological orderHalc. 12:25 15 nov Clearly my title "Is an Evolutionary Cosmology possible?" declares my bias. I am trying to explain how I believe that an evolutionary cosmology could work within the bounds of current thinking and cannot expand all the arguments in this restricted format.
In the same way the black hole that internally created a universe as large and complex as ours in a different set of dimensions from ours will fade out and vanish in time.
Read further and think. Consider the physical evolution of particles atoms and stars through time which we understand quite well and use the analogy to consider ow physical laws might evolve. physical evolution in a cooling universe favours things that last longest in time. our laws settle out forma an infinite dimensional potential the way they do because they tend to favour the things that last longest in a metastable state.
Thermodynamics is not violated by my proposals and the energy (and mass!) created by the collapse of the matter inside the event horizon cannot be observed outside.
Now a couple of general notes to thinkers on this subject There is no reason to believe that physical laws change abruptly as an event horizon is lost.
What we see of material entering the event horizon is irrelevant what happens is what the individual leptons and quarks "experience" as they interact furiously a vast number of times in their relatively long passage towards the theoretical "singularity".
Can I stress again that What I am talking about is what based on our knowledge of physics and relativity will happen in the early stages of the collapse inside the event horizon
To help illustrate this let me consider an isolated large black hole with a mass of around 10E9 solar masses the sort of thing that exists at the centre of many large galaxies but without the complications of a lot of other material nearby orbiting it at high speeds I will use the results from the website http://xaonon.dyndns.org/hawking/ to illustrate what it event horizon looks like.Its radius is 19.75 AU or about 3E9 KM Very similar to the orbit of UranusIts surface gravity is around 1550 earth gravities. Compare this with the surface gravity of a white dwarf star of 350,000 gravities. Physical laws are not distorted under these conditions.
The gravity gradient at the surface is only about 1E-9 Less than that on the earth
It is quite clear that a theoretical space ship could cross this without any stress problems
