New model of cosmic stickiness favors 'Big Rip' demise of universe
The universe can be a very sticky place, but just how sticky is a matter of debate.
The ins and outs of quantum chromodynamics
Quarks and antiquarks are the teeny, tiny building blocks with which all matter is built, binding together to form protons and neutrons in a process explained by quantum chromodynamics (QCD).
New technique for isolating sunny-day 'light' scattering could help illuminate Universe's birth
Astrophysicists have developed a new method for calculating the effect of Rayleigh scattering on photons, potentially allowing researchers to better understand the formation of the Universe.
Detector at the South Pole explores the mysterious neutrinos
Neutrinos are a type of particle that pass through just about everything in their path from even the most distant regions of the universe. The Earth is constantly bombarded by billions of neutrinos, which zip right through ...
Is the Higgs boson a piece of the matter-antimatter puzzle?
(Phys.org) —Several experiments, including the BaBar experiment at the Department of Energy's SLAC National Accelerator Laboratory, have helped explain some – but not all – of the imbalance between matter and antimatter ...
Telescopes hint at neutrino beacon at the heart of the Milky Way
(Phys.org) —Identifying the sources of high-energy neutrinos—ghostly but potentially information-rich particles believed to be generated by some of the most violent objects in the sky—is near the top of many an astrophysicist's ...
X-ray telescopes find black hole may be a neutrino factory
(Phys.org) —The giant black hole at the center of the Milky Way may be producing mysterious particles called neutrinos. If confirmed, this would be the first time that scientists have traced neutrinos back to a black hole.
Maybe it wasn't the Higgs particle after all
Last year CERN announced the finding of a new elementary particle, the Higgs particle. But maybe it wasn't the Higgs particle, maybe it just looks like it. And maybe it is not alone.
Solving the riddle of neutron stars
It has not yet been possible to measure the gravitational waves predicted by Einstein's theory of general relativity. They are so weak that they get lost in the noise of the measurements. But thanks to the latest simulations ...
