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, ...
Free falling: Einstein's equivalence principle holds that the motion of freely-falling bodies (whether apples, oranges, or anything else) is independent of their composition. The Cold Atom Laboratory ...
In the late 1500s, the Italian scientist Galileo Galilei conceived of an experiment that changed a foundation of physics. He mulled — and by some accounts actually tested — what would happen if two ...
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 ...
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 ...
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 ...
