Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

General relativity explains gravity as the distortion of space-time. Quantum mechanics explains other forces using exchanged "virtual particles." Unifying gravity with quantum mechanics is a major ...

It isn’t often that physics produces news that diverts the mainstream media from politics, crime and sports. But, now, in the space of four years’ time, physicists have twice elevated the intellectual ...

Now for the first time, this controversial theory has been tested experimentally and has held its ground. An independent study of the distribution of gravity around more than 30,000 galaxies found ...
