As computers become progressively faster and more powerful, they’ve gained the impressive capacity to simulate increasingly realistic environments.

For all we understand about the universe, 96 percent of what’s out there still has scientists in the dark. Astronomical observations have established that familiar matter--atoms--accounts for only 4 percent of the weight of the cosmos.

By Eugenie Samuel Reich of Nature magazine As Earth's biggest "ear" on the Universe, the giant 305-meter radio dish at Arecibo , Puerto Rico, has played a part in groundbreaking discoveries, searches for alien civilizations and the occasional Holly

A little over a decade ago astronomers discovered something astonishing. They were looking at exploding stars in the distant universe, and they noticed that not only is the universe expanding from its big bang origin, but its expansion is actually speeding up

According to standard physics textbooks, quantum mechanics is the theory of the microscopic world. It describes particles, atoms and molecules but gives way to ordinary classical physics on the macroscopic scales of pears, people and planets

As Star Trek is so fond of reminding us, we're carbon-based life forms. But the event that jump-started the universe, the Big Bang, didn't actually produce any carbon, so where the heck did it – and we – come from?

(PhysOrg.com) -- Like gravity, the strong interaction is a fundamental force of nature. It is the essential "glue" that holds atomic nuclei—composed of protons and neutrons— together to form atoms, the building blocks of nearly all the visible matter in the universe. Despite its prevalence in nature, researchers are still searching for the precise laws that govern the strong force

(PhysOrg.com) -- Cosmologists Alan Coley from Canada's Dalhousie University and Bernard Carr from Queen Mary University in London, have published a paper on arXiv, where they suggest that some so-called primordial black holes might have been created in the Big Crunch that came before the Big Bang, which lends support to the theory that the Big Bang was not a single event, but one that occurs over and over again as the universe crunches down to a single point, then blows up again, over and over.

Dark matter. Nobody knows what it is, but it's thought to make up a quarter of the universe

(PhysOrg.com) -- A team of physicists from the United States and Russia announced today that it has developed a means for computing, with unprecedented accuracy, a tiny, temperature-dependent source of error in atomic clocks.

As children, we all learn about numbers. We start with counting, followed by addition, subtraction, multiplication and division. But mathematicians know that the number system we study in school is but one of many possibilities

Baby boomers have been nicknamed the "Silver Tsunami" for their impact on every facet of society. Now, as 76,000,000 of them reach age 60 and beyond, it seems they either can't or don't want to stop working.

(PhysOrg.com) -- The AMS particle detector will take off on 29 April 2011 at 21.47 CEST onboard the very last mission of the space Shuttle Endeavour.

It was just a colour out of space--a frightful messenger from unformed realms of infinity beyond all Nature as we know it; from realms whose mere existence stuns the brain and numbs us with the black extra-cosmic gulfs it throws open before our frenzied eyes. Science-fiction author H
