Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

Photonic space-time crystals are materials that could increase the performance and efficiency of wireless communication or laser technologies. They feature a periodic arrangement of special materials ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you purchase ...

If you wave your hand in front of your face, you won’t notice anything particularly interesting. Perhaps a gentle waft of air against your cheek – that’s about it. No epiphany. No major sign that ...

From "runaway" black holes shooting across the cosmos to secret planets in our own backyard, space is overrun with mysterious objects that scientists are clamoring to explain. Here are five of the ...

(Nanowerk News) Photonic time crystals consist of materials with uniform composition in space but properties that vary periodically over time. With this periodic variation, the spectral composition of ...
