Researchers at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, have identified a promising new method for measuring the mass of galaxies orbiting the Milky ...
Atom interferometry exploits the wave nature of ultracold atoms to measure gravitational acceleration and its spatial variations with exceptional precision. In a typical configuration, laser pulses ...
Astronomers have found a clever new way to slice and dice the flickering light from a distant star in a way that reveals the strength of gravity at its surface. That is important because a star’s ...
Scientists are closer to unravelling the mysterious forces of the universe after working out how to measure gravity on a microscopic level. Experts have never fully understood how the force works in ...
A bundle of magnets and glass had a slight but detectable gravitational pull, pushing scientists closer to the boundary between classical and quantum physics. Reading time 3 minutes Despite keeping us ...
