In the whole course of physics I observed a very common thing present around us which is symmetry. Symmetry leads to stability everywhere. For example:-Pauli's Exclusion principle tends to make the electronic distribution symmetrical in orbitals. Next example is the non-symmetrical distribution of materials In earth's core leads to instability of earth. In general symmetry leads to stability in nature.

I want to ask why nature prefers symmetrical systems over non symmetrical systems?

  • $\begingroup$ I think I disagree with your premise that more symmetrical systems tend to be more stable. For a counterexample, if I have a ferromagnetic material, formed of a collection of magnetic dipoles, the system is initially rationally symmetric. The lowest energy configuration, however has all the dipoles aligned in some direction (although there is no reason to pick one direction over another). This means that you need to break your initial symmetry to find the most stable configuration. $\endgroup$ – By Symmetry May 5 '19 at 13:04
  • $\begingroup$ @By Symmetry Hi Is universe symmetrical about a point? As it is stable so I think that it must be symmetrical! $\endgroup$ – Shreyansh Pathak May 5 '19 at 14:26
  • $\begingroup$ One line of reason goes as follows: Symmetry constrains a system. With enough symmetry you might end up with a unique solution... $\endgroup$ – Qmechanic Jun 15 '19 at 9:03
