Cosmological natural selection proposes that every black hole forming in our universe could spark the birth of a new universe.
Physicists have pondered why our universe seems finely tuned for life, with fundamental constants like electron mass and force strength just right.
The anthropic principle and multiverse theory suggest that our universe's parameters are favorable for life due to countless universes with varied constants.
Lee Smolin's Cosmological Natural Selection theory draws parallels between biological evolution and universe formation.
The theory posits that black hole formation triggers new universe creation with slightly altered fundamental constants, akin to genetic mutations.
The process leads to universes evolving to optimize black hole production, potentially favoring life emergence.
The theory's testability hinges on the optimization of fundamental parameters for black hole production independently of those for life.
Lee Smolin suggests a test involving the strange quark mass determining the cutoff between neutron stars and black holes.
The theory's implications raise questions about the fine-tuning of fundamental constants and the role of luck in the emergence of life.
While speculative, Cosmological Natural Selection offers a natural explanation for fine-tuning and parallels biological evolution, encouraging scientific exploration.

Zahaqiel points out the challenge in defining a reference class using the example of defining it as "homo sapiens sapiens existing concurrently with the internet" and how this impacts predictions about the internet's future existence based on self-sampling assumptions and internet access trends.
The text illustrates the importance of considering prior knowledge when defining a reference class through examples like the Prince of France scenario and Adam and Eve's situation, highlighting the potential misuse of the doomsday argument in different contexts.
