Try to fathom the power of 1 million nuclear power plants. Now, imagine there is a way to pack the equivalent of that into the pulse of a laser beam—even if it’s only for one quadrillionth of a second ...

Later experiments demonstrated that light also behaves as particles ... result in optical processors that are faster and more ...

Physicists may need to come up with a new theory for how the universe works, after a dark energy experiment has produced confounding results.

Title: Light Light is a form of energy. When we say light, we mean the energy that we can detect with our eyes. When light enters our eyes, our brain interprets this into images we can ‘see’.

To investigate the reflection of light by different types of surface, and the refraction of light by different substances. Remove the block. Join the crosses to show the paths of the light rays ...

Several experiments were built to find answers, including the Dark Energy Spectroscopic Instrument (DESI) at the Kitt Peak National Observatory near Tucson Arizona. It consists of 5,000 optical ...
