Not all light is made equal. Now, a team of physicists has discovered that photons can travel differently to any other light that scientists have seen in the past.
There’s no pot of gold at the end of the rainbow but there are some colorful visuals you can trip out on if you can figure out how to stare the right way. Here’s a video that supposedly shows a camera gliding through the spectrum of a rainbow and making its way through ROYGBIV backwards.
Popular answers to this question included “silver,” “white,” “whatever color it’s reflecting,” and “no color at all.” But most mirrors are actually very faintly green. Yes, green.
Since today was a monumental day for gay rights in America, it’s only fitting that we share this science image, showing all of the colors emitted by the sun. Why are there gaps in the spectrum? Those are our star’s missing colors. Read all about it here.
The twinkly flashing lights of fireflies are a classic sign of summer, but the insects aren’t blinking for your aesthetic benefit. They’re courting in an absolutely cutthroat meet market, and some scientists are afraid that human activities could be making it harder for them to succeed. This summer, you can help…
Short film Chronemics, by London animation studio Animade, is set in a world where robot-like stick figures who dwell in light and darkness push against each other, with surprising results. The animation is simple, the tone is cheeky, and who knew stick figures could have so much personality?
We recently outlined the best upgrades for your office, but now it's time to shed some light on the desk lamp situation. Which lamp is most deserving of real estate on your desk? Tell us in the comments.
Normally, light zips through a vacuum at a blazing 186,282 miles per second. But as a new experiment by Scottish physicists has shown, this isn't always necessarily the case.
A new Harvard study is re-affirming the assertion that reading light-emitting e-books before bed, like computer tablets, could have a detrimental effect on sleep, which can in turn lead to serious health problems.
Normally, photons want nothing to do with one another. Light waves just pass through each other like ghosts. But now, for the first time ever, scientists at the University of Vienna have coaxed a strong interaction between two single photons. It's an achievement that opens up radical new possibilities for a number of…
Mirrors, lenses and reflective surfaces are combined to arresting effect in this commercial for au Hikari, a Japanese high-speed optical ISP. The machine's optics work as one to reflect, focus, and diverge a single beam of light through a series of tasks, causing it to singe, melt and illuminate as it goes.
If stars themselves are giant balls of gas and appear as dots in the night sky, why is it so common to draw them with pointed arms? Minute Physics explains how the light from stars interacts with our eyes to create that "star-shaped" image.
Halos and light pillars are optical phenomena created by light passing though ice crystals to create brilliant arcs and columns in the sky. While it's a very natural phenomenon, the effect can appear eerily supernatural.
Scientists have worked out an easy way of turning light into matter, a process thought to be impossible when first proposed 80 years ago. The proposed experiment would recreate events that occurred in the first 100 seconds of the Big Bang.
When wave pass through each other, they interfere, producing neat effects. Artist Gary Drostle harnesses the interference patterns as light passes through rippling water to create fish pond mosaics.
Researchers from MIT have developed a camera that can take pictures in almost total darkness. It works by mathematically reconstructing 3D images from single photons reflected from dimly lit objects. The achievement could result in stealthy spy cameras, or treat eyes that are easily damaged by excess light.
This is, without a doubt, the coolest way to make a black hole. It's what happens when physics overdoses on poetry and mumbles to itself in an alleyway. It's when light inverts itself.
The Sun emits an impressive range of visible light. Some colors, however, are more strongly represented than others – while others are missing entirely.
Feast your eyes on Nuance, a captivating short by artist Marc-Antoine Locatelli that features dancer Lucas Boirat interacting with an ever-morphing army of frenetic photons.
