Is the Universe a Bubble? – Physicists Work on the Multiverse Hypothesis

July 21, 2014

1 Comment

In several new studies and a short video, researchers from the Perimeter Institute for Theoretical Physics detail their work on the multiverse hypothesis. Perimeter Associate Faculty member Matthew Johnson and his colleagues are working to bring the multiverse hypothesis, which to some sounds like a fanciful tale, firmly into the realm of testable science. Never […]

ATLAS Collaboration Detects Process Even Rarer Than Higgs Particle

July 17, 2014

1 Comment

A new published study from the ATLAS Collaboration reports the first evidence of a process that can be used to test the mechanism by which the recently discovered Higgs particle imparts mass to other fundamental particles. Scientists running the ATLAS experiment at the Large Hadron Collider (LHC), the world’s largest and most powerful “atom smasher,” […]

New Observations Reveal How Electrons Accelerate in the Van Allen Radiation Belts

July 16, 2014

0 Comments

Using new data from the Van Allen Probes, a newly published study reveals the first direct observation of two processes that, in a chain, cause the acceleration of electrons in Earth’s outer radiation belt. One of the great, unanswered questions for space weather scientists is just what creates two gigantic donuts of radiation surrounding Earth, […]

New research from the RIKEN Center for Emergent Matter Science reveals how arrays of electrons trapped in nanoscale circuitry could form the basis for future scalable quantum computers. A single electron trapped in a semiconductor nanostructure can form the most basic of building blocks for a quantum computer. Before practical quantum computers can be realized, […]

Solid-State Physicists Consider the ‘Anticrystal’

July 8, 2014

0 Comments

Physicists show that the anticrystal, a theoretical solid that is completely disordered, should undergird our understanding of most materials. For the last century, the concept of crystals has been a mainstay of solid-state physics. Crystals are paragons of order; crystalline materials are defined by the repeating patterns their constituent atoms and molecules make. Now physicists […]

The Reinterpretation of Cold Dark Matter as a Bose-Einstein Condensate

July 2, 2014

4 Comments

Newly published research signifies the reinterpretation of cold dark matter, opening up the possibility that it could be regarded as a very cold quantum fluid governing the formation of the structure of the Universe. Tom Broadhurst, an Ikerbasque researcher at the UPV/EHU’s Department of Theoretical Physics, has participated alongside scientists of the National Taiwan University […]

New Buckyball Research Will Aid Biological Studies

June 30, 2014

0 Comments

Using SLAC’s Linac Coherent Light Source X-ray laser, researchers take a closer look at soccer-ball-shaped carbon molecules called buckyballs. Scientists at SLAC have been blowing up “buckyballs” – soccer-ball-shaped carbon molecules – with an X-ray laser to understand how they fly apart. The results, they say, will aid biological studies by improving the analysis of […]

Three Closely Orbiting Supermassive Black Holes Could Help in the Search for Gravitational Waves

June 26, 2014

0 Comments

An international team of astronomers discovered three closely orbiting supermassive black holes that could help in the search for gravitational waves. An international team, including Oxford University scientists, led by Dr Roger Deane from the University of Cape Town, examined six systems thought to contain two supermassive black holes. The team found that one of […]

New CERN Research Details Evidence of the Direct Decay of the Higgs Boson to Fermions

June 24, 2014

0 Comments

New research published in Nature Physics details strong evidence of the direct decay of the Higgs boson to fermions. If evidence of the Higgs boson revealed two years ago was the smoking gun, particle physicists at Rice University and their colleagues have now found a few of the bullets. The European Organization for Nuclear Research […]
