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 ...

Physicists have taken quantum strangeness to an extraordinary new level by measuring light across 37 dimensions. Their groundbreaking experiment pushes quantum mechanics beyond classical expectations, ...

Everyone is familiar with the light dome that shows from afar where cities are brightly lit at night. Artificial light that is scattered in the atmosphere and brightens the night sky can have an ...

Light can do more than illuminate a material. In some cases, it can temporarily change how electrons move through it. That ...

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 ...

Physicists have discovered that when beams of light interact at the quantum level, they can generate ghost-like particles that briefly emerge from nothing and affect real matter. This rare phenomenon, ...
