For instance: when Hawking first wrote about the Anthropic Principle, he and other cosmologists were focused on why gravity is weak enough to allow the Universe to expand for billions of years yet just strong enough to allow galaxies, stars, and planetary systems to form. At the time they thought its tuning had a tolerance of about 0.5 percent. Since then, however, physicists have been astonished to find that the Cosmological Constant — the mysterious pushback that just ever-so-slightly counters gravity’s inward rush — is just strong enough, no more and no less, to a precision of more than a hundred decimal places. No one has been able to deduce any physical reason why it should be as it is. The Anthropic Principle is here to stay.
You just have to read the entire article. Much of this is covered in scientific detail in ]], but nevertheless, it is worth being reminded of the philosophy inherent in such things.
