A dark point inside a beam of light should not be much of a traveler. Yet in a new experiment, some of those points appeared ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

In day-to-day life, light seems intangible. We walk through it and create and extinguish it with the flip of a switch. But, like matter, light actually carries a little punch—it has momentum. Light ...

The concept of light has fascinated scientists for centuries. A recent MIT experiment has reignited the debate about its dual nature. The MIT team revisited a classic experiment with unprecedented ...

Albert Einstein postulated in his 1905 theory of special relativity that the speed of light in a vacuum is constant. Ever ...

Much of what we know about plant circadian rhythms is the result of laboratory experiments where inputs such as light and temperature can be tightly controlled. Less is known about how these ...
