In his final paper on the multiverse hypothesis, the world’s best-known atheist made a supernatural creator more plausible
Scientists have discovered a surprising fact about our universe in the past 40 years: against incredible odds, the numbers in basic physics are exactly as they need to be to accommodate the possibility of life. If gravity had been slightly weaker, stars would not have exploded into supernovae, a crucial source of many of the heavier elements involved in life. Conversely, if gravity had been slightly stronger, stars would have lived for thousands rather than billions of years, not leaving enough time for biological evolution to take place. This is just one example – there are many others – of the “fine-tuning” of the laws of physics for life.
