Einstein Wins Again: Space Satellite Confirms Weak Equivalence Principle

Enlarge / There is a long tradition of experimental testing of the weak equivalence principle, the basis of Albert Einstein’s theory of general relativity. GOOD One of the most counter-intuitive notions in physics is that all objects fall at the same rate, regardless of their mass, i.e. the principle of equivalence. This was memorably illustrated …

A Fundamental Principle Of General Relativity Just Passed Its Toughest Test Yet

A fundamental tenet of Einstein’s theory of general relativity has just passed its most rigorous test yet. Using a specially designed satellite, an international team of scientists measured the accelerations of pairs of free-falling objects in Earth orbit. Results based on five months of data indicated that accelerations differed by no more than 1 part …
