Could the equivalence principle be wrong? New Measurements Test Einstein’s Theory of Relativity – The Debrief

by
Antikythera Mechanism

Gravity accelerates objects equally, despite differences in their mass or composition. This fundamental principle of modern physics was known in the 16th century thanks to the observations of Galileo Galilei, which were later confirmed by astronaut Dave Scott during the Apollo 15 moonwalk. What do you know! Mr. Galileo was right, Scott said during a … Read more

Gravity still holds: Einstein’s theory of relativity is strong after the quantum challenge

Gravity quantum physics illustration concept

The researchers confirmed a fundamental assumption of physics with unprecedented accuracy that the various properties of mass, such as weight, inertia and gravitation, are always equivalent, regardless of the specific composition of the mass involved. This reinforces the equivalence principle, essential to Einstein’s theory of relativity, and addresses a critical point of divergence between classical … Read more
