Closer to measuring gravity in the quantum world - Physics and Mathematics. Step forward to measure quantum gravity, the phenomenon that could solve one of the greatest puzzles in physics.
The gravitational attraction of the smallest mass ever was measured by the experiment described in the journal Science Advances and led by Tim Fuchs, of the University of Southampton. By understanding quantum gravity - he concluded - we could solve some of the mysteries of our universe, for example how it began or what happens inside black holes.
