Physicists Quote by Alan Lightman
““Theoretical physicists are Platonists. Until the last few years, they believed that the entire universe, the one universe, was generated from a few principles of symmetry and mathematical truths, perhaps throwing in a handful of parameters like the mass of the electron. It seemed that we were closing in on a vision of our universe in which everything could be calculated, predicted, and understood. However, two theories in physics, called “eternal inflation” and “string theory,” now””

Physicists once thought the universe could be fully described by simple symmetry principles and few parameters, but modern theories like eternal inflation and string theory reveal deeper complexity and many possible realities.
In simple terms: Physicists once believed simple rules explained everything, but new theories show the universe is far more complex.
