During ten seconds of weightlessness Brynle Barrett from the Laboratory of Photonics, Numerical Sciences and Nanosciences at the University of Bordeaux monitors an experiment to test the ‘weak equivalence principle’ – or why a feather in a vacuum falls as fast as a hammer.

Astronomers have discovered the first pulsar (PSR J0337+1715) with two stars circling it. By watching the three objects orbit one another, observers will soon be able to perform the best-ever test of the "strong equivalence principle", which is a key prediction of Albert Einstein's general theory of relativity. #astrophysics

Uniformly Accelerating Charged Particles: A Threat to the Equivalence Principle (Hardcover)

The equivalence principle is key to understanding that light is deflected by gravity, and to understanding gravitational redshift.
