Simulators of Super-Dense Stars

Authors: George Rajna

Rice University physicists have created the world's first laser-cooled neutral plasma, completing a 20-year quest that sets the stage for simulators that recreate exotic states of matter found inside Jupiter and white dwarf stars. [35] An international group of astronomers has detected an intense and extremely luminous gamma-ray flare from one of high-redshift blazars known as DA 193. [34] Our universe could be the mirror image of an antimatter universe extending backwards in time before the Big Bang. [33] "As you celebrate New Year's Day, cast an eye upward and think for a moment about the amazing things our country and our species can do when we set our minds to it," Stern wrote in the New York Times on Monday. [32] Our senses are stuck in the past. There's a flash of lightning, and then seconds pass until we hear the rumble of distant thunder. We hear the past. [31] ESA's technical centre in the Netherlands has begun running a pulsar-based clock. The "PulChron' system measures the passing of time using millisecond-frequency radio pulses from multiple fast-spinning neutron stars. [30] VR is an almost perfect avenue for this approach, since it has been surging in popularity as both entertainment and an educational tool. [29] Using MAGIC telescopes and NASA's Fermi spacecraft, an international team of astronomers has discovered a new source of very high energy gamma-ray emission around the supernova remnant (SNR) G24.7+0.6. [28] In 1973, Russian physicist A.B. Migdal predicted the phenomenon of pion condensation above a critical, extremely high-several times higher than that for normal matter-nuclear density. [27] Our first glimpses into the physics that exist near the center of a black hole are being made possible using "loop quantum gravity"-a theory that uses quantum mechanics to extend gravitational physics beyond Einstein's theory of general relativity. [26] In the shadowy regions of black holes two fundamental theories describing our world collide. Can these problems be resolved and do black holes really exist? First, we may have to see one and scientists are trying to do just this. [25]
