In what may be one of the most mind-bogglingly surreal experiments ever floated, scientists at the US Department of Energy's Fermi National Accelerator Laboratory (Fermilab) will attempt to discover if the universe is "real" or merely a holographic 3-D illusion that we just think is real. Using high-powered lasers, the scientists intend to determine if space-time is a quantum system made up of countless tiny bits of information.  Read More

Researchers at Imperial College London have devised a method of achieving light to matter ...

In what could be a landmark moment in the history of science, physicists working at the Blackett Physics Laboratory in Imperial College London have designed an experiment to validate one of the most tantalizing hypotheses in quantum electrodynamics: the theory that matter could be created using nothing more than pure light.  Read More

Illustris simulation still frame centered on the most massive galaxy cluster existing toda...

As you might expect, the scale and complexities of the underlying physics means creating a realistic virtual universe would require some hefty computing power. A team of astronomers is claiming to have achieved this impressive feat using a computer simulation called "Illustris," which took five years to program and, for the first time, can recreate the evolution of the Universe in high fidelity.  Read More

The BICEP2 facility at the South Pole has discovered compelling evidence for quantized gra...

In a discovery that has profound implications for our understanding about the beginnings of the universe, the Harvard-Smithsonian Center for Astrophysics this morning announced evidence of so-called primordial B-modes in the cosmic microwave background (CMB). These B-modes directly show quantum gravitational waves originating during the inflationary period of cosmic evolution, from about 10-36 sec to 10-32 sec after the Big Bang, and give us a direct view of physical processes taking place at 1016 GeV – a trillion times more energetic than particle collisions at the Large Hadron Collider.  Read More

The ANU SkyMapper telescope at the Siding Spring Observatory has discovered the oldest kno...

A team of astronomers at The Australian National University (ANU) working on a five-year project to produce the first comprehensive digital survey of the southern sky has discovered the oldest known star in the Universe. Just a 6,000 light year astronomical hop, skip and jump from Earth, the ancient star formed shortly after the Big Bang 13.7 billion years ago.  Read More

That the Universe is largely composed of a cosmic web consisting of narrow filaments upon which galaxies and intergalactic gas and dust are concentrated has been known for more than a decade. While a great deal of evidence for this has accumulated, visual evidence has been difficult to find. Astronomers have now photographed what appears to be a segment of a cosmic filament stimulated into fluorescence by irradiation from a nearby quasar.  Read More

The spherical middle chamber of DarkSide-50 is filled with 7,000 gal of scintillator fluid

Like the Higgs Boson, dark matter is one of those things in the Universe that evidence points to, but is very difficult to pin down. A team of researchers is looking to verify the existence of this most elusive of ingredients that is thought to make up 23 percent of the Universe using powerful detectors buried deep in an Italian mountain.  Read More

Mark your calendars for 2034, because that is when science is set to get a whole new spectrum to play with when the European Space Agency (ESA) launches its eLISA mission. Consisting of a constellation of three spacecraft flying in precise formation, eLISA will study gravitational waves in a manner that may one day revolutionize our understanding of the Universe.  Read More

The Universe is big, and so is the challenge of understanding its large-scale structure (P...

Our knowledge of the large-scale structure of the Universe is gradually taking shape. However, our improved vision is mostly being statistically squeezed from huge data sets. Working backward from a statistical analysis to a putative fact about the (singular) Universe, to which statistics do not apply on a cosmological scale, is a dicey business. A case in point is a recent look at the biggest known structures in the Universe – large quasar groups.  Read More

Astronomers at UC Riverside have combined observations from space and ground telescopes to discover what they say is the oldest known galaxy with a precisely measured distance, seen as it was just 700 million years after the Big Bang.  Read More
