Physicists propose that black holes can be used as an aid in modeling the behavior of electrons flowing inside modern unconventional superconductor materials. The thing about these materials is that they tend to start off as insulators, and then become superconducting.A very precise set of conditions is necessary for... |

Though the Large Hadron Collider (LHC) is operational at this point, engineers working on the international project are painfully aware that the largest physics experiment in the world is more than a year behind schedule. It is also operating at a fraction of the energy it is capable of, analysts add, and the current... |

Scientists at the Rice University have recently determined that certain types of superconductors are able to carry electrons indefinitely – as in to store electrical energy – only if those electrons have certain magnetic properties. The new discovery, which was made by US and Chinese experts, may help phy... |

The large number of passenger, cargo and military jet airplanes out there today significantly contributes to global warming and climate change. Primarily, the craft do so by burning fossil fuels and releasing significant amounts of pollution in the air, but they also create contrails. These are exhaust byproducts tha... |

Arguably the most dangerous stage of a space flight is the reentry into the Earth's atmosphere. The process is so harsh that space agencies involved in the International Space Station (ISS) use it to destroy the resupply capsules completely. They are steered into the incorrect angle, and they burn up and disinte... |

The main issue plaguing researchers trying to devise quantum computers today is the fact that it's considerably more difficult to entangle electrons than it is to entangle photons. If that became a reality, then experts could finally use superconductor materials as a source of entangled electrons, which could le... |

For a very long time, researchers have tried, unsuccessfully, to turn hydrogen into metal. This is known to be possible, and, probably, this form of the chemical is present on other planets, most likely gas giants, but it's impossible to obtain the material here on Earth. It has tremendously large pressure requi... |
