By creating space-like conditions in a slim 4-meter vessel, Italian researchers have helped confirm the behavior of astrophysical jets -- streams of charged particles shot out by supermassive black holes and young stars, which stretch several hundred thousand light years across space.

 | When black holes slam into each other, the surrounding space and time surge and undulate like a heaving sea during a storm. This warping of space and time is so complicated that physicists haven't been able to understand the details of what goes on -- until now. ...> Full Article |
 | Black holes are some of the heaviest objects in the universe. Electrons are some of the lightest. Now physicists at the University of Illinois at Urbana-Champaign have shown how charged black holes can be used to model the behavior of interacting electrons in unconventional superconductors. ...> Full Article |
Chinese researchers have successfully built an electromagnetic absorbing device for microwave frequencies. The device, made of a thin cylinder comprising 60 concentric rings of metamaterials, is capable of absorbing microwave radiation, and has been compared to an astrophysical black hole (which, in space, soaks up matter and light).

 | Using observations with NASA's Chandra X-ray Observatory and ESA's XMM-Newton, astronomers have announced a robust detection of a vast reservoir of intergalactic gas about 400 million light years from Earth. This discovery is the strongest evidence yet that the "missing matter" in the nearby Universe is located in an enormous web of hot, diffuse gas. ...> Full Article |
Scientists at Rochester Institute of Technology have won time on one of the fastest computers in the world in their quest to "shine light" on black holes and test unexplored aspects of Einstein's General Theory of Relativity. The team is also collaborating with scientists at other institutions to create an open toolkit and cyberinfrastructure to model black holes, neutron stars and accretion disks.

 | University of Nevada, Reno researcher and faculty member Roberto Mancini is studying ultra-high temperature and non-equilibrium plasmas to mimic what happens to matter in accretion disks around black holes. The research will enable astrophysicists to better understand what happens around black holes and in active galactic nuclei. Scientists will also better understand the application of high-energy density plasmas to energy production, such as controlled nuclear fusion (produced in the laboratory), and production of X-ray sources for a variety of applications. ...> Full Article |
Despite their popularity in the science fiction genre, there is much to be learned about black holes. In a paper published in the August 20 issue of Physical Review Letters, the flagship journal of the American Physical Society, Dartmouth researchers propose a new way of creating a reproduction black hole in the laboratory on a much-tinier scale than their celestial counterparts.

The Sherman Fairchild Foundation has awarded $3.1 million to the California Institute of Technology (Caltech) to support the Caltech-Cornell Program for Simulation of eXtreme Spacetimes (SXS) through 2013.

The universe as we currently know it is made up of three dimensions of space and one of time, but researchers are exploring the possibility of an extra dimension.
