From the most distant stars in the sky to the screen in front of your face, light is everywhere. But the exact nature of ...

Scientists really don't understand time... but they do have some theories about what it might (and might not) be.

"These single atoms are like the smallest slits you could possibly build." For over 100 years, quantum physics has taught us that light is both a wave and a particle. Now, researchers at the ...

Frank Close tells us about the history of particle physics, and what it means that charge in our universe's matter is so closely balanced. When you purchase through links on our site, we may earn an ...

An illustration conveying the idea of a space-based quantum internet, which would seem, like the hypothetical particle of a tachyon, to outpace light. An illustration ...

For the first time, physicists have simulated what objects moving near the speed of light would look like — an optical ...

In today’s SISOFBDRU (stuff I shared on Facebook but don’t really understand) news, we have the very first photograph of “light as both a particle and wave,” pictured above. And woah, how PLUR (look ...

In 1964, physicist John Bell formulated what became known as Bell's Theorem, showing that if quantum mechanics is correct, ...
