How Warm Is Light? Physicists Create A Bose-Einstein Condensate 'Super-Photon'

Physicists from the University of Bonn have developed a completely new source of light, a Bose-Einstein condensate consisting of photons, something not known to be possible, which may potentially be suitable for designing light sources resembling lasers th ...

Solar Sails Are Already Old Tech- Get Ready For Solar Wings

We know that light has mass and that beaming enough light at something can push it away- solar sails that will move a craft through the cosmos are based on this idea and NASA tested that concept earlier today when it launched NanoSail-D, a nanosatellite (c ...

Have Researchers Found A Way To Spot Rotating Black Holes?

One thing you probably know about black holes, no matter how much science you took, is that they have never actually been seen.   Instead, the science consensus is that masses that sit at the centers of galaxies like our own Milky Way are presumed to be bl ...

Restoring Hearing Using Infrared Light

University of Utah scientists have used invisible infrared light to make rat heart cells contract.  Sounds interesting but not revolutionary, right?   But they also used infrared light to cause toadfish inner-ear cells to send signals to their brain- which ...

How To Make Time Invisible

Researchers from Cornell say that by using a bit of electromagnetics wizardry they can create a 'hole' in space and keep it hidden- spatial cloaking.   Invisible time. We see things using light, of course, namely as light scatters on an object.   ...
