Gravitational Wave Observatory Reaches Beyond The Quantum Limit
The Laser Interferometer Gravitational - Wave Observatory ( LIGO ) has transcend its premature stratum of precision , determine a way to get around the quantum limit – the universe - intrinsical racket that used to cut back how precisely gravitational waves could be measured . The observatory uses lasers to spot variations in distance - time that are 1/1,000ththe breadth of a single proton , and there is a lot find at that level ....
