We understand that objects/mass entering a Blackhole are superheated to unimaginable temperatures. As things get compressed even further as they descend in towards the singularity, I would imagine that they get hotter and hotter at an exponential rate?  Where does all that energy go........ Big Bang somewhere else?

That is an interesting and difficult question that most current professional workers in this field by avoiding and talking about point and ring "singularities"  and the need to formulate a quantum theory of gravity before it can be tackled.

I feel that this is a bit like saying that our current universe is uninteresting because it all ends in the heat death as the energy runs out and the universe becomes more spread out.

I am confident that current knowledge of relativistic dynamics and high energy physics could allow us to build more detailed models that take us a long way inside a black hole and that doing this could reveal some interesting ideas that could help with a more complete solution to this problem question.

I personally have some detailed hypotheses but they are in the area of new theories and you can find them there by looking for evolutionary cosmology and not part of standard thinking yet.

I recieved this personal email which is really related to this topic so I have posted the mail and the reply here


I read your response to a question about the temperature of a singularity at http://www.thenakedscientists.com/forum/index.php?topic=36265.0. The question pertained to ever increasing temperature. I tend to look at the situation from a different standpoint--I'm just an interested novice. A singularity is supposed to have so much gravity that even atoms are crushed. If the the protons, neutrons, and electrons were crushed they would no longer move and there would be no energy. Without energy, wouldn't the core of a singularity be at absolute zero?

Sincerely,

Temperature is not a function of the space available for movement but the energy  (velocity) of the particles that are moving.  The concept of a mathematical "singularity" is as invalid as the concept of a mathematical "infinity" when talking about physical things.  Whatever happens there is always room to move even if this is less than the planck limits.  However it is clear that when this happens some significant changes will take place and the formation of another "big bang" is a distinct possibility.

Roger Penrose in his latest book "Cycles of Time" shows that how in a vastly expanded ancient universe consisting solely of radiation the concepts of scale and time are lost and suggest that it is then quite possible to have conditions matching the big bang in his Conformal Cyclic Cosmology.  To my mind the same thing could happen when gravitational collapse happens. If everything was forced to become pure energy scale space and time would also be lost.  However he tends to dismiss this idea in his book by saying that it is turbulent and not like the smooth big bang.  I disagree and suggest that if he modelled the idea properly he would see that as you suggest the extreme compression would quite quickly force everything to become smooth and coherent energy just like his description of the conditions after googles of years of expansion.
