Phys.org / Black holes do not exist where space and time do not exist, says new theory
(Phys.org) —The quintessential feature of a black hole is its "point of no return," or what is more technically called its event horizon. When anything—a star, a particle, or wayward human—crosses this horizon, the black ...
Phys.org / Popper's experiment realized again—but what does it mean?
(Phys.org)—Like Einstein, the philosopher Karl Popper was a realist who was deeply bothered by some of the odd implications of quantum mechanics. Both Popper and Einstein disliked the idea in Heisenberg's uncertainty principle, ...
Phys.org / First-of-its-kind tube laser created for on-chip optical communications
(Phys.org)—Nanophotonics, which takes advantage of the much faster speed of light compared with electrons, could potentially lead to future optical computers that transmit large amounts of data at very high speeds. Working ...
Phys.org / Reversible solid-to-liquid phase transition offers new way to synthesize crystals
(Phys.org) —The simple acts of heating and cooling affect different substances in different ways: some substances may change phase from solid to liquid to gas, while others may irreversibly break down when heat is applied. ...
Phys.org / Water-soluble silicon leads to dissolvable electronics
(Phys.org)—Researchers working in a materials science lab are literally watching their work disappear before their eyes—but intentionally so. They're developing water-soluble integrated circuits that dissolve in water or ...
Phys.org / How well can information be stored from the beginning to the end of time?
(Phys.org)—Information can never be stored perfectly. Whether on a CD, a hard disk drive, or a piece of papyrus, technological imperfections create noise that limits the preservation of information over time. But even if ...
Phys.org / Metasurface solves calculus problems as an analog computer
Scientists have demonstrated that a 2-D man-made material called a metasurface can perform spatial differentiation and integration, the two main types of calculus problems, when illuminated by a laser beam. Essentially, the ...
Phys.org / Metamaterial prism creates a reverse rainbow
(Phys.org)—In a normal rainbow, red is always on "top" while violet is on the "bottom." This is true whether the rainbow is created by a glass prism or by water droplets in the sky, and is due to the way that these materials ...
Phys.org / Super-insulated clothing could eliminate need for indoor heating
(Phys.org)—By wearing clothes that have been dip-coated in a silver nanowire (AgNW) solution that is highly radiation-insulating, a person may stay so warm in the winter that they can greatly reduce or even eliminate their ...
Phys.org / Thermal memory thrives at extremely high temperatures
(Phys.org)—While the performance of electronic memory devices degrades at high temperatures, a newly proposed memory actually requires temperatures in excess of 600 K to operate. Called NanoThermoMechanical memory, the new ...
Phys.org / Thermodynamic analysis reveals large overlooked role of oil and other energy sources in the economy
(Phys.org)—The laws of thermodynamics are best known for dealing with energy in the context of physics, but a new study suggests the same concepts could help improve economic growth models by accounting for energy in the ...
Phys.org / Thermoelectric power plants could offer economically competitive renewable energy
(Phys.org)—A new study predicts that large-scale power plants based on thermoelectric effects, such as small temperature differences in ocean water, could generate electricity at a lower cost than photovoltaic power plants.
Phys.org / Attack on classical cryptography system raises security questions
(Phys.org)—How secure is completely secure? In the world of secure communication, a scheme may be completely secure until it's not—that is, until an attack is proposed that reveals a weak spot in the scheme. This is what's ...
Phys.org / Your chance of becoming globally famous depends on the language you speak
(Phys.org)—Is there a connection between language and fame? A recent study has found that the number of famous people a country produces is more strongly correlated to that country's language than to its wealth or population. ...
Phys.org / 'Fibonacci quasiparticle' could form basis of future quantum computers
(Phys.org)—Topological quantum computing (TQC) is a newer type of quantum computing that uses "braids" of particle tracks, rather than actual particles such as ions and electrons, as the qubits to implement computations. ...
