A Johns Hopkins University professor was one of a trio of scientists awarded the 2011 Nobel Prize in physics Tuesday for discovering that the universe is expanding at a faster and faster rate, contrary to science's conventional wisdom.

Three U.S.-born scientists won the Nobel Prize in physics on Tuesday for overturning a fundamental assumption in their field by showing that the expansion of the universe is constantly accelerating.

(AP) -- Aside from the slogan on the water tower that reads "City of Energy," there is little in this leafy Chicago suburb of gently rolling hills to indicate that it has been the center of the universe when it comes to studying, well - the universe.

By successfully confining atoms of antihydrogen for an unprecedented 1,000 seconds, an international team of researchers called the ALPHA Collaboration has taken a step towards resolving one of the grand challenges of modern physics: explaining why the Universe is made almost entirely of matter, when matter and antimatter are symmetric, with identical mass, spin and other properties. The achievement is remarkable because antimatter instantly disappears on contact with regular matter such that confining antimatter requires the use of exotic technology.

(PhysOrg.com) -- “We know that about 25% of the matter in the universe is dark matter, but we don’t know what it is,” Michael Kesden tells PhysOrg.com. “There are a number of different theories about what dark matter could be, but we think one alternative might be very small primordial black holes.”

(PhysOrg.com) -- The Universe wouldn't be the same without the Higgs boson. This legendary particle plays a role in cosmology and reveals the possible existence of another closely related particle.

Although astronomers only slowly came to realize dark matter’s importance in the universe, for me personally it happened in an instant. In my first project as a postdoc at the University of California, Berkeley, in 1978, I measured the rotational velocities of star-forming giant molecular clouds in the outer part of the disk of our Milky Way galaxy.

Scientists looking to capture evidence of dark matter -- the invisible substance thought to constitute much of the universe -- may find a helpful tool in the recent work of researchers from Princeton University and New York University.

Peter was gay; Raymond was a homophobe.

Intense magnetic fields were probably generated in the universe shortly after the Big Bang, according to an international team led by Christoph Federrath and Gilles Chabrier of the CRAL (Centre de Recherche Astrophysique de Lyon, France). The project offers the first explanation for the presence of intergalactic and interstellar magnetized gas

By Ron Cowen of Nature magazine Physicists last week announced evidence that particles of dark matter--the invisible, hypothetical material believed to make up more than 80 percent of the mass of the Universe--may have a lower mass than suspected.

(PhysOrg.com) -- According to the cosmological principle, there is no special place or direction in the universe when viewed on the cosmic scale. The assumption enabled Copernicus to propose that Earth was not the center of the universe and modern scientists to assume that the laws of physics are the same everywhere. Due to the cosmological principle, scientists also assume that the universe is “homogeneous” - having a uniform structure throughout - and “isotropic” - having uniform properties throughout.

(PhysOrg.com) -- An incredibly rare sub-atomic particle decay might not be quite as rare as previously predicted, say Cornell researchers. This discovery, culled from a vast data set at the Collider Detector at Fermilab (CDF), is a clue for physicists trying to catch glimpses of how the universe began.
