A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

The latest dark matter experiment kicks off this week, as physicists aim to identify the universe's most enigmatic particles. Reading time 2 minutes Long tubes, strong magnets, and bright lasers. Is ...

You can gaze upward at night to see a veritable ocean of stars, but the visible parts of the universe are just a fraction of the total. The rest, we think, is dark matter and dark energy, which are by ...

Lawrence Livermore National Laboratory's National Ignition Facility (NIF) is the hottest place on Earth for the briefest of moments during an experiment. Now, it can be one of the brightest places ...

Physicists are no longer content to simply listen to ripples in spacetime. A new proposal sketches out how an exquisitely tuned laser experiment could, in principle, nudge gravitational waves ...
