Symmetry in basic physical laws.
Recent physical experiments suggest that chirality is not a purely chemical phenomenon, but seems to be an inherent feature of basic physical laws. A fundamental physical principle (the CPT theorem) connects asymmetry in space with the "arrow of time," and shows that such an arrow exists even on the level of mesons.
