Lee Smolin and Daughter universes...
He postulates that daughter universes can arise from black holes. How is this so?

vincentm said:Ok, postulate was a bad word for the purpose of this discussion, thanks for the information i'll pour over it soon as get home from work.
marcus said:In science, empirical science, the Baconian method in case anyone has forgotten, you are not supposed to propose a theory unless it can be falsified by some future experiment. It has to bet its life on some prediction of some possible observation that COULD go against it.
It can't be infinitely adaptible so that it would accommodate any possible outcome of any future observation. If it is that accomodating it is MUSH having no predictive or explanatory value----i.e. not science.
Like saying the universe is compatible with the existence of conscious life. Because what observation could ever show that it was not compatible with life?
A lot of "multiverse" talk is like that and is not science.
The CNS conjecture challenges you to find some possible modification of the fundamental constants which would increase astrophysical black hole abundance.
It PREDICTS, in effect, that you cannot find any slight tweaking of the constants which, if done, would make the universe have more black holes
This prediction has been standing since 1993 when Smolin published it, and people have TRIED and they have so far FAILED to falsify the CNS conjecture. You can try. See if you can think of something. If you can you will have refuted CNS and it will be shot down.
One way would be if an astronomer found a neutron star with more than 1.6 solar mass, because that would show that tweaking the mass of the top quark so as to make that neutron star collapse to hole would be possible.
If someone finds a 1.7 solar mass neutron star that will prove that our universe is NOT OPTIMIZED FOR HOLES.

Lee Smolin is a theoretical physicist and professor at the Perimeter Institute for Theoretical Physics. He is known for his contributions to the fields of quantum gravity and cosmology. Daughter universes refer to a concept in theoretical physics where our universe is just one of many universes that may have branched off from a parent universe.
Lee Smolin's idea of daughter universes is based on the theory of cosmological natural selection. It suggests that new universes can be created through the process of black holes forming and giving rise to new universes with slightly different physical laws and constants.
The concept of daughter universes provides a possible explanation for the fine-tuning of the laws and constants in our universe. It suggests that these values may have been selected through the process of natural selection, rather than being randomly determined.
The concept of daughter universes is a theoretical idea that is still being explored and debated in the scientific community. While there is evidence to support the concept, it is not yet a widely accepted idea and further research is needed to fully understand its implications.
The concept of daughter universes is one possible explanation for the existence of a multiverse. It suggests that our universe may be just one of many universes that exist within a larger multiverse, with each universe having slightly different physical laws and constants.
