Question
JAYAN,

PLEASE READ, AT LEAST DOWN TO THE PART WERE "LEE SMOLIN" MIGHY BE ON TO SOMETIMNG WITH HIS WILD IDEA THAT BLACK HOLES GIVE BIRTH TO NEW UNIVERSES!


Russell E. Rierson
Expertise:  It's fractals all the way down. Inside the event horizon is another universe: Space "density" continually increases as a function of time. Analogous to being inside a black hole, yet we do not feel the crushing force, because our atoms are shrinking in correspondence to the increasing density of space-time. We are, after all, made OF space-time. Yes, the laws of physics break down at the "Planck scale" which is the basis of my conjecture. From chaos, comes complex self organization. order-->chaos-->order--> ... chaos--order...

****************** Lee Smolin might be onto something with his wild idea that black holes give birth to new universes. I take the logic one step further and postulate a theory of quantum gravity. Our universe could really be the inside of a collapsed star from a parent universe. The physics for a compactified dimension of radius R is the same for the physics of a compactified dimension of radius 1/R. There is no need to hypothesize an external hyperspace for the "baby universe" to expand into. As the star collapses, approaching the Plank scale, it becomes a chaotic "quantum foam". This chaos self organizes into a compressed quantum universe. So what we observe as an absolute spacetime expansion is not really true. The expansion is relative. From a local perspective, the universe appears to expand with radius R. From a global perspective energy density is compressed with radius 1/R. The only real constant for the universe is "h", which is Planck's constant. All other physical constants are related to this basic evolutionary parameter ...h, an energy density ratio. The singularity then becomes a limit that is approched but never reached. If the locality principle is not going to be thrown into the trash heap, then a viable option is that space is something analogous to homogeneously distributed probability density functions(a perfect fluid?) i.e. increasing energy-density gradients, giving the observed thermodynamic arrow of time. The observed cosmic expansion is, again, a "relative" one. A perspective effect from our local vantage point. A shrinking object gives the illusion of receding motion. Increasing *refractive* density gradients give the appearence of a doppler-red-shift. Space increases density as matter is re-sized. Quantum Gravity. Solve the Swcharzschild solution for the entire universe. Solve for the imaginary time value of the Schwarzchild solution using analytic continuation, which becomes periodic in the imaginary time direction. Quantum field theory calculations where imaginary time is periodic, with period 1/T are equivalent to statistical mechanics calculations where the temperature is T. The periodic waveforms that are opposed yet "in phase" would be at standing wave resonance, giving the action, also, equivalent to an observed statistics for evaporation of black holes. As the energy density continues to be compressed, it becomes a quantum gravitational refractive effect, with paths of light rays being deflected by energy density variations. Light rays are deflected near massive objects As the compression approaches singularity, the local observers will percieve an asymptotically flat, expanding universe. I can answer all questions regarding the "Unified Field Theory"

Answer
Hi Peter,
Yes read all of it.
Sagan in his Cosmos also "ruminated" along similar lines..
picturing universes within universes..reminds me of the universe being holographic.
(an atom contains the cosmos!)
This is an old Indian metaphysical concept.
That is why the adepts in mahabharatan times never needed weapons of any sort for their wars.
A blade of grass could be turned into  the famed "brahmastra", a mighty and deadly weapon against which there was no defence!
