The Perfect Liquid -- Now Even More Perfect
January 17, 2012 — How liquid can a fluid be? This is a question particle physicists have been working on. The “most perfect liquid” is nothing like water, but the extremely hot quark-gluon-plasma which is ... > full story -
One Clock With Two Times: When Quantum Mechanics Meets General Relativity
October 20, 2011 — General relativity, the joint theory of gravity, space and time gives predictions that become clearly evident on a cosmic scale of stars and galaxies. Quantum effects are fragile and observed on ... > full story -
Gravitational Waves That Are 'Sounds of the Universe'
October 3, 2011 — Einstein wrote about them, and we're still looking for them -- gravitational waves, which are small ripples in the fabric of space-time, that many consider to be the sounds of our universe. Just as ... > full story -
Light from Galaxy Clusters Confirms General Theory of Relativity
September 28, 2011 — All observations in astronomy are based on light (electromagnetic radiation) emitted from stars and galaxies and, according to the general theory of relativity, the light will be affected by gravity. ... > full story -
Squeezed Laser Will Bring Gravitational Waves to the Light of Day
September 11, 2011 — Measuring at the limits of the laws of nature -- this is the challenge which researchers repeatedly take up in their search for gravitational waves. The interferometers they use here measure with ... > full story -
Recalculation of the Potsdam Geoid Shows Time-Dependent Variation of Gravity
June 29, 2011 — The "Potsdam Gravity potato", as this representation of terrestrial gravity has become known, can for the first time display gravity variations that change with time. The seasonal fluctuations of the ... > full story -
New Physics Research to Deepen Understanding of the Universe
June 22, 2011 — Physicists in the UK are beginning a new research project which aims to improve our understanding of the universe and the material within it. They also hope that their work will enable better ... > full story -
Physicists Apply Einstein's General Theory of Relativity to Superconducting Circuits
June 10, 2011 — Using Einstein's general theory of relativity, scientists have demonstrated that the Josephson junction could be reproduced. The Josephson junction, a device that was first discovered by Brian David ... > full story -
New Hope of Detecting Gravitational Waves: Final Piece of Einstein's Jigsaw Puzzle
May 26, 2011 — Direct evidence of the existence of gravitational waves is something that has long eluded researchers. However, new research has suggested that adding just one of the proposed detectors in Japan, ... > full story -
Dark Energy Is Driving Universe Apart: NASA's Galaxy Evolution Explorer Finds Dark Energy Repulsive
May 19, 2011 — A five-year survey of 200,000 galaxies, stretching back seven billion years in cosmic time, has led to one of the best independent confirmations that dark energy is driving our universe apart at ... > full story
