If we assume that the constants of nature fluctuate near the singularity when a black hole forms (assuming, also, that physical black holes really do form singularities) then a process of evolution of universes becomes possible. We explore the implications of such a process for the origin of life, interstellar travel, and the human future. Keywords Quantum gravity * Evolution * Anthropic principle * Black holes, In his excellent book The Life Of The Cosmos (1998), Lee Smolin has proposed that if the quantum theory of gravity has two special features the universe would fine tune [...]

In the years since I first thought of the possibility of producing artificial black holes, my focus on it has shifted from the role of life in the universe to a practical suggestion for the middle-term future, which I think of as on the order of a few centuries. Keywords General relativity * Black holes, I think I need to apologise a bit for my paper. I am a mathematical physicist by choice, and only a philosophe 'malgre lui'. My (2010) paper was initially written [...]
