I believe there are three questions in Martin Rees’s “Our Cosmic Habitat” that could very well be linked together. They refer to the very first instants or everything before the Big Bang, the evolution of the universe, and life on other planets. Rees raises the following question in chapter 4: “How did 13 billion years of evolution lead from such a simple recipe to our complex habitat where¾ here on earth and perhaps on other worlds¾ atoms assemble into creatures able to ponder their origins?” We now have a fairly good idea of how the universe got to where it is now. According to the Big Bang theory (which is widely accepted), the entire universe was once an extremely hot, extremely dense object that has been expanding for approximately the past 15 billion years. The first millisecond of cosmic history is a period filled with uncertainties in the basic physics, since we cannot recreate the conditions existent at that time in experiments.
