(Phys.org) —A trio of researchers working in France, along with a colleague from the U.K. has re-measured the gravitational constant using the same apparatus they built 12 years ago and have found a small change. In their ...
In July, physicists were ecstatic in announcing preliminary results pointing to the discovery of the long-sought Higgs boson particle. The Higgs boson is a tiny subatomic particle that apparently weighs about 130 times as ...
