Scientists have demonstrated after decades of theorising how light interacts with vacuum, recreating a bizarre phenomenon predicted by quantum physics. Oxford University physicists ran simulations to ...

Light has always been described as an elegant partnership of electric and magnetic fields, yet for nearly two centuries physicists treated the magnetic side as a quiet background player. New ...

A team of scientists has found that the narrow beam of a laser, under specific conditions, can cast a shadow — a counterintuitive finding that could open the doors for new applications of optical ...

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 ...

Dozens of times over the last decade NASA scientists have launched laser beams at a reflector the size of a paperback novel about 240,000 miles (385,000 kilometers) away from Earth. They announced ...
