"Revolutionizing Physics: Tiny Gravity Experiments Yield Major Breakthrough"

European physicists have successfully measured the strength of gravity on the smallest scale ever using a tabletop experiment, marking a significant step forward in understanding the universe's fabric and potentially advancing quantum gravity theories. The experiment, conducted by researchers at Leiden University, the University of Southampton, and the Institute for Photonics and Nanotechnologies, involved measuring a force of around 30 attonewtons on a particle with just under half a milligram of mass. This achievement could pave the way for testing quantum gravity theories and resolving the contradictions between general relativity and quantum mechanics, although further work is needed to push tabletop experiments to even smaller scales.
