Casimir cavities are mysterious spaces between microscopic metal plates in a vacuum. Areas of diminished energy between the plates cause them to push toward each other, as if trying to fill the ...

As you read this, the screen is probably flashing over 240 times per second, yet, as a human, you won't notice this ...

Researchers have found a way to mimic lightspeed when photographing an object. The method involves stitching together many thin “slices” of light reflecting off the object. Photography—itself a ...

Everyone knows the number for the speed of light — but almost nobody knows the uncomfortable truth behind it. Measuring light in one direction requires perfectly synchronized clocks, and that’s the ...

This video explores a physics thought experiment about light, motion, and relativity, explaining what science predicts would happen if a car could travel at the speed of light. Farmers are aging.

The method involves stitching together many thin “slices” of light reflecting off an object.

Two Virginia Democratic senators, Jennifer Boysko of Herndon and Lashrecse Aird of Petersburg, helped advance SB 306 and SB 297 patroned by Republican Sen. Mark J. Peake on Jan. 22, bills that would ...

Today, wearable LED technology that targets specific concerns—most of which involve chasing youth—is more accessible than ever.

CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and ...

A new Stanford-designed optical amplifier uses energy recycling in a resonator to deliver strong, low-noise amplification with far less power.

Light is the fastest phenomenon in the universe, clocking in at just under 300,000 kilometers per second. The telescopes that observe that light, from radio waves to gamma rays, are built at rather ...
