Top 10 Best Physics Experiments in History

The 1887 attempt to detect the luminiferous aether found no evidence of its existence, demolishing a cornerstone of classical physics and setting the stage for Einstein's special relativity.

Henry Cavendish's 1798 torsion balance measurement of the gravitational constant effectively weighed the Earth and provided the first precise value of G in Newton's law of gravitation.

Ernest Rutherford's 1911 experiment fired alpha particles at gold foil and discovered that atoms have a tiny, dense nucleus, overthrowing the plum pudding model of the atom.

Robert Millikan's 1909 experiment measured the charge of a single electron with remarkable precision, confirming that electric charge comes in discrete quantized units.

Galileo's systematic 1600s measurements of balls rolling down inclined planes established the law of uniform acceleration and laid the groundwork for Newtonian mechanics.

Arthur Eddington's 1919 measurement of starlight bending around the Sun during a total eclipse provided the first empirical confirmation of Einstein's general theory of relativity.

Experiments confirming Einstein's 1905 explanation that light ejects electrons from metals in quantized packets provided critical evidence for quantum theory and earned him the Nobel Prize.

In September 2015, LIGO detected spacetime ripples from two merging black holes 1.3 billion light-years away, confirming a century-old prediction of general relativity with staggering precision.

Chien-Shiung Wu's 1956 experiment demonstrated that the weak nuclear force does not conserve parity, shattering the long-held assumption that the laws of physics are symmetric under mirror reflection.
