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 ...

For the first time in space, scientists have produced a mixture of two quantum gases made of two types of atoms. Accomplished with NASA's Cold Atom Laboratory aboard the International Space Station, ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

Particles with mind-bending quantum properties still follow a standard gravitational rule, at least as far as scientists can tell. The equivalence principle — one of the central tenets of Einstein’s ...

How Einstein's equivalence principle extends to the quantum world has been puzzling physicists for decades, but a research team has now found the key to this question. How Einstein's equivalence ...

One of the most counter-intuitive notions in physics is that all objects fall at the same rate, regardless of mass, aka the equivalence principle. This was memorably illustrated in 1971 by NASA Apollo ...

Back in December, I praised SyFy's new space opera The Expanse for getting gravity right by understanding the Equivalence Principle. This is the idea that the effects of gravity and acceleration ...
