Sir Isaac Newton formulated the law of gravity.
By using a therom call hubbles law and hubbles constant this is the calculation: 1/Ho=d/v=t t= 3.09x10 22/71000x31566926 t=13.738 billion years old

Hubble's Law states that (more or less) the distance to a galaxy is a constant multiple of the distance to that galaxy. For example, if one galaxy is moving away from us at three times the speed of another galaxy, then that means it is also three times as far away. The Law indicates that the Universe is expanding and had a beginning. Before Hubble's Law, many astronomers thought that the Universe did not have a beginning (it always existed).

The law of refraction was first accurately described by Ibn Sahl, of Baghdad, in the manuscript On Burning Mirrors and Lenses (984).it was then properly formulated by snell
Robert Boyle of course ! He was a chemist.

Rudolf Clausius, a German mathematician and physicist formulated the law of conservation of energy clearly. Though William Rankine mentioned it but he did not formulate it as clearly as Clausius did.
