Pauli's Exclusion Principle

Wolfgang Pauli revolutionised Physics with his statement " that no two similar electrons can exist in the same atom".

This came to be known as the Pauli's Exclusion Principle. One electron excludes any similar electron.

In the heavens, we find that the Solar System is like the Atom. The electrons revolve in elliptical orbits around the central nucleus. Similarly the planets traverse in elliptical orbits around the central Sun. " As Above, So Below" !

Kepler in his first Law of Planetary Motion opined that planets move in elliptical orbits with Sun as the Focus of the Ellipse !

If you extend the Exclusion Principle, we find that in the Solar system, no two planets are alike ! Jupiter differs from Mercury and so on !
