In new studies published in Physical Review Letters and a special issue of Classical and Quantum Gravity on September 14, a team of researchers present the most precise test yet of the Weak ...

Physicists in Germany have used an atomic interferometer to perform the most accurate ever test of the equivalence principle at the level of atoms. Sebastian Fray and colleagues at the Max Planck ...

The MICROSCOPE mission tested the weak equivalence principle with free-falling objects in a satellite. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

At the heart of Einstein’s theory of gravity (general relativity) is the equivalence principle. The equivalence principle says that there is no difference between being stationary and subject to ...

The Equivalence Principle states that gravity and acceleration are the same. It is at the core of General Relativity, which ...

As the story goes, Italian astronomer Galileo Galilei ascended the Leaning Tower of Pisa in the 16th century to drop two spheres of different masses at the same time—proving that they would land on ...

(Phys.org) —Einstein's equivalence principle states that an object in gravitational free fall is physically equivalent to an object that is accelerating with the same amount of force in the absence of ...

New research proves theoretically that the Weak Equivalence Principle can be violated by quantum particles in gravitational waves - the ripples in spacetime caused by colossal events such as merging ...

Scientists have demonstrated that Einstein's theory of general relativity is correct to a remarkable degree of accuracy, despite having been around for more than a century. The team behind the ...

Researchers present the most precise test yet of the weak equivalence principle, a key component of the theory of general relativity. The report describes the final results from the MICROSCOPE mission ...
