Researchers Slow The Speed Of Light As It Travels Through A Vacuum

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. » 1/23/15 12:40pm 1/23/15 12:40pm

Scientists May Have Figured Out How to Turn Light into Matter

Back in 1934, a team of physicists came up with an idea for how one might create matter from light. Put simply, just slam two photons into each other to get an electron and a positron, a.k.a. matter. And now, some 80 years later, a team of physicists have a plan to carry out the experiment in real life. » 5/19/14 12:20pm 5/19/14 12:20pm

Scientists Figured Out a Way to Cheat Newton's Third Law

Ever since the late 17th century, it's been understood that to every action there is an equal and opposite reaction. That's Newton's Third Law of Motion. But a group of German scientists recently came up with a trick that appears to break that law, one that lets light accelerate all by itself. And it could bring us… » 10/15/13 7:00pm 10/15/13 7:00pm

Photons Can Communicate From Beyond the Grave

Everyone knows that quantum physics is weird—but it just got weirder. Because a team of scientists from the University of Jerusalem have used quantum entanglement to allow two photons that never existed at the same time to communicate with each other. » 6/05/13 8:49am 6/05/13 8:49am

What Is Light, Anyway?

First you're taught that light is wave. Then you get a little older and your teacher explains that it's actually particles called photons. Wait, which is it then? Particles? Waves? Both? Neither? This video should help explain. » 2/20/13 7:07am 2/20/13 7:07am

These Are the Oldest Photons In the Universe

This is the entire view sky as seen from Earth, taken by the Planck observatory during a whole year. In the center, the microwave radiation of our galaxy, the Milky Way. But that's not the important part. » 7/06/10 10:20am 7/06/10 10:20am

Major Milestone Reached in the Quest For Star Trek Style Teleportation

I don't understand quantum mechanics. Physicists don't even really understand it. But somehow, information was successfully teleported over a full meter, which means we're that much closer to making Star Trek a dorktastic reality. » 1/24/09 4:00pm 1/24/09 4:00pm

3D Translucent Laser Display Will Turn Windows Into Billboards

Sony has teamed up with the Max-Planck Institute in Germany to create a flexible, translucent display that creates 3D multi-color images from laser beams. The all-organic screen uses a chemical reaction called photoexcitation to render images, where energy moves from the lasers to the screen and “turns on” the… » 10/08/08 3:15am 10/08/08 3:15am
