Using a conventional computer and cutting-edge mathematical tools and code, physicists at the Center for Computational Quantum Physics (CCQ) at the Simons Foundation’s Flatiron Institute and collaborators at Boston University have cracked a daunting quantum physics problem previously claimed to be solvable only by quantum computers.
Black holes are regions in space where gravity is so strong that nothing, even light, can escape. Einstein’s theory of general relativity breaks down inside black holes, either by the presence of a so-called “curvature singularity” or “Cauchy horizon.”
Officer Nicholas O’Malley was indicted on a manslaughter charge in the fatal shooting of a man who had just carjacked a woman on March 11
In his 1964 paper, “Transmission of Information by Extraterrestrial Civilizations,” famed astrophysicist and radio astronomer Nikolai Kardashev addressed the types of transmissions (and at what energies) astronomers should search for in their Search for Extraterrestrial Intelligence (SETI). As part of his analysis, Kardashev proposed a universal scale for classifying the technological advancement of civilizations based on their overall energy consumption. The resulting Kardashev Scale (as it came to be known) came down to three categories.
An unusual thermoelectric effect has been observed in the semiconductor tellurium by RIKEN physicists for the first time. This demonstration points to the potential of similar materials to be used in applications such as energy harvesting and advanced heat management.
A research team in China has reported a significant piezoelectric effect in ultrathin and ultra-flexible polycrystalline diamond membranes. This pioneering discovery challenges a century-long scientific dogma that diamonds are strictly non-piezoelectric.
Preliminary results of a study presented at the recent European Geosciences Union General Assembly in Vienna indicate that hellish Venus-type planets may be about twice as common as habitable planets that form with oceans.
A planet that is about the size of Saturn, but with a temperature more like Earth’s, has an atmosphere rich in methane, according to a new study using NASA’s James Webb Space Telescope (JWST).
Suppose there are signs of extraterrestrial life and we have not yet been able to detect them. What does that mean? In Nature Astronomy, researchers discuss the consequences of these so-called false-negative results. “We are currently investing a great deal of money in missions that might need to be designed differently.”
A team from Vienna and Frankfurt has found a formula describing a strange phenomenon: Space and time can form a kind of “crystal” that may turn into a black hole. The results are described in Physical Review Letters.
Among dozens of changes recommended by a 100-page IACP report, boxing will be permanently banned at the academy following the death of Enrique Delgado-Garcia
Larry Bushart spent 37 days in jail before his charges were dropped; Perry County Sheriff Nick Weems cited a meme referencing a school shooting as the reason for the arrest
The man, who was on parole for armed robbery, was on the run after shooting a man who tried to stop him from sexually assaulting a woman when he fired at Pasadena officers
Within a crystal’s atomic structure, tiny atomic-scale flaws will naturally occur where electrons can become trapped. These defects have emerged as one of the leading platforms for quantum information processing. Through a new study, posted to the preprint server arXiv, Ilai Schwartz and colleagues at NVision Imaging Technologies in Germany have shown that a specialized molecule embedded inside a crystal could take this approach a step further, offering a more controllable and versatile route to building quantum systems.
It’s a truism among oceanographers that there is more accurate mapping of the surface of the moon and Mars than of the deep-ocean floor. That’s especially true for the Bismarck Sea, a relatively deep body of water north of Papua New Guinea. It’s an ocean basin with a geologically complex seafloor rife with faults, volcanic features, rifts, scarps, and active subduction and spreading zones at depths that make high-resolution sonar mapping challenging.
