John P. Millis, PhD for redOrbit.com - Your Universe Online For several decades now the leading model for the origin and evolution of the known Universe is a concept known as the Big Bang. Nearly 15 billion years ago, quantum fluctuations of the infinite vacuum of space-time caused the emergence of a rapidly expanding Universe, ultimately filled with matter and radiation. But what initially caused the fluctuation? According to quantum mechanics, it is a natural result of the...

New experiments show that common scientific rules can apply to significantly different phenomena operating on vastly different scales. The results raise the possibility of making discoveries pertaining to phenomena that would be too large or impractical to recreate in the laboratory, said Cheng Chin, associate professor in physics and the James Franck Institute at the University of Chicago. Chin and associates Chen-Lung Hung, Xibo Zhang and Nathan Gemelke will publish their results in the...

Hydrogen is the most abundant element in the universe and is a major component of giant planets such as Jupiter and Saturn. But not much is known about what happens to this abundant element under high-pressure conditions when it transforms from one state to another. Using quantum simulations, scientists at the Lawrence Livermore National Laboratory, the University of Illinois at Urbana-Champaign and the University of L'Aquia in Italy were able to uncover these phase transitions in the...

Convincing experimental evidence finally found for directed percolation A team of physicists has, for the first time, seen convincing experimental evidence for directed percolation, a phenomenon that turns up in computer models of the ways diseases spread through a population or how water soaks through loose soil. Their observation strengthens the case for directed percolation's relevance to real systems, and lends new vigor to long-standing theories about how it works. Their experiment is...

Using rigorous computer calculations, researchers from Carnegie Mellon University and the Carnegie Institution of Washington have established evidence that supercooled silicon experiences a liquid-liquid phase transition, where at a certain temperature two different states of liquid silicon exist. The two states each have unique properties that could be used to develop new silicon-based materials. Furthermore, the methods developed can be applied to gain a better understanding of other...

Álvaro Corral, a physicist at the Universitat Autònoma de Barcelona, has discovered that the structure of the recurrence time of earthquakes, which is the time interval between successive earthquakes, is similar to the spatial structure of physics systems when they change phase in the "critical points". The research has been and shows that the time interval between successive earthquakes depends on the time that elapsed between previous...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
