There are precision measurements, and then there’s the Laser Interferometer Gravitational-Wave Observatory. In each of LIGO’s twin gravitational wave detectors (one in Hanford, Washington, and the ...

No one can question the impact of science on human civilization, and the importance of experimentation in science is equally undeniable. Some experiments confirm what we already know, others suggest a ...

Sam Baron receives funding from the Australian Research Council. Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever ...
