Observing the Sun could lead to the discovery of hidden photons, astrophysicists say. These are elementary particles that are the result of dark matter interacting with the regular stuff. Experts are convinced they will find these photons soon.While looking at the Universe, astrophysicists figured out a relatively si... |

Metamaterials are a very special class of materials that are engineered specifically for a certain job. Though they are basically common chemical elements, or mixes thereof, their internal structures are arranged differently than they are in nature. As such, metamaterials can be used for a variety of applications for... |

One of the main things black holes are known for is, erm, being black. They are not colorless per se, they just do not allow light to bounce of them, and therefore determine a color. All materials that absorb photons are generally considered to be black, but now astronomers say that the supermassive behemoths at the ... |

The dual nature of light, as in the fact that it can act like both a particle and a wave, has had physicists puzzled since that was first discovered. Such a duality was bound to lead to some paradoxes, scientists hypothesized at the time, and now their predictions appear to be coming true. Scientists have recently di... |

At this point, optical fiber is able to focus beams of light into extremely narrow space. AS light travels through the wire, the latter gets narrower and narrower, until it finally reaches a thickness of only a few hundred nanometers. From that moment on – depending on the wavelength of the light itself –... |
