Tao Te Ching is the first simple dialectic and philosophical "theory of relativity" in the world. When science approaches the unified theory or the ultimate ontological analysis of the universe, it will inevitably encounter and return to the most traditional monism of eastern mysticism philosophy-Laozi's way of "making something out of nothing" or Sakyamuni's "origin of emptiness". This is the result that I finally realized after returning from modern physics to Tao Te Ching and Buddhism and "opening up" the "two threads" of science and traditional oriental mysticism philosophy.
