A 1990 work by Kolb and Turner called The Early Universe wonders how this concept ever advanced beyond being an idea, while Linde attempted to explain one type of this concept by proposing a model of "eternal chaotic inflation." Another treatise titled after a cosmological form of this concept notes that the ratio of the electric force of a proton and an electron to their gravitational force is approximately equal to the ratio of the age of the universe to the time it takes for light to cross an atom. That work by Barrow and Tippler accepts the (*) tautologically weaker form of this idea, whose name Brandon Carter coined. Its stronger form essentially argues that the observable universe is restricted to conditions that allow for the presence of human life. For 10 points, identify this "principle" in the philosophy of physics which accounts for the low probability of the existence of life.
