Sean Carroll: Distant time and the hint of a multiverse

Floating Gyroscopes Vindicate Einstein Four superconducting pingpong balls floating in space have just confirmed two key predictions of Einstein’s general theory of relativity, physicists announced in a press conference Wednesday. “We have completed this landmark experiment testing Einstein’s universe, and Einstein survives,” said physicist Francis Everitt of Stanford University, the principal investigator on NASA’s Gravity Probe B mission. The probe, which launched in 2004, was designed to test the effect Earth’s gravity has on the space-time around it.

Kepler-22b a 'Super-Earth' that could hold life: NASA New planet 'like' Earth NASA has confirmed another planet with characteristics like Earth, and potentially habitable. 6, 2011 Sandhill Dunnart The sandhill dunnart (Sminthopsis psammophila) is a species of small carnivorous Australian marsupial of the family Dasyuridae. It is known from four scattered arid areas of Australia: near Lake Amadeus in Northern Territory, the central Eyre Peninsula in South Australia, the southwestern edge of the Great Victoria Desert in Western Australia, and Yellabinna Sand Dunes in South Australia.[3] Description[edit]

It's not that orbitals invalidated the stick-and-ball models of chemistry at all. If anything orbitals explained to us why the bonds are arranged as they are in stick-and-ball models. Prior to quantum theory, we only knew the geometry and patterns of those bonds by experiment. Prior to quantum theory, chemistry had no general theory to explain why atomic bonds are shaped as experiment revealed them to be.

A Lenticular Galaxy Reveals Spinning Black Holes In the heart of MCG-6-30-15, a galaxy 130 million light-years away, there is a hole. It’s as big around as the orbit of Mars. Into this hole stars and star stuff are always falling—a lot of stuff, the equivalent of a hundred million suns so far.

Ars Oblivionalis - The Art of Forgetfulness - Stojadinovi ć Ars Oblivionalis Scientists release most accurate simulation of the universe to date The Bolshoi supercomputer simulation, the most accurate and detailed large cosmological simulation run to date, gives physicists and astronomers a powerful new tool for understanding such cosmic mysteries as galaxy formation, dark matter, and dark energy. The simulation traces the evolution of the large-scale structure of the universe, including the evolution and distribution of the dark matter halos in which galaxies coalesced and grew. Initial studies show good agreement between the simulation's predictions and astronomers' observations. "In one sense, you might think the initial results are a little boring, because they basically show that our standard cosmological model works," said Joel Primack, distinguished professor of physics at the University of California, Santa Cruz. "What's exciting is that we now have this highly accurate simulation that will provide the basis for lots of important new studies in the months and years to come."
