In 1905, at the age of merely 8 years old, Mary was alive when the German born physicist, Albert Einstein, proposed the Special Theory of Relativity: 1) that observers can never detect uniform motion except relative to other objects and that 2) unlike the velocity of massive objects, the speed of light is a constant and is the same for all observers independent of their constant velocity toward or away from the light source.
