Atom Interferometer Provides Most Precise Test Yet of Einstein's Gravitational Redshift
February 17, 2010 — Using an atom interferometer, scientists have tested one of the foundations of Einstein's general theory of relativity: that time slows down in a gravitational field. Their experiment proves that ... > full story -
Astronomers Get New Tools for Gravitational-Wave Detection
January 5, 2010 — A breakthrough in discovering new millisecond pulsars is providing astronomers a greatly improved capability to use those natural cosmic tools to make the first direct detections of gravitational ... > full story -
Black Holes in Star Clusters Stir Up Time and Space
December 20, 2009 — Within a decade scientists could be able to detect the merger of tens of pairs of black holes every year, according astronomers. By modeling the behavior of stars in clusters, the team finds that ... > full story -
Laser-Plasma Accelerators Ride On Einstein's Shoulders
November 2, 2009 — Using Einstein's theory of special relativity to speedup computer simulations, scientists have designed laser-plasma accelerators with energies of 10 billion electron volts (GeV) and beyond. These ... > full story -
Theorists Attempt To Determine Whether Particle Physics And String Theory Can Be Reconciled
September 22, 2009 — A new toolkit of equations will help theorists determine whether a promising agreement between particle physics and string theory is fact or ... > full story -
Precise Radio-Telescope Measurements Advance Frontier Of Gravitational Physics
September 1, 2009 — Scientists using a continent-wide array of radio telescopes have made an extremely precise measurement of the curvature of space caused by the Sun's gravity, and their technique promises a major ... > full story -
Rewriting General Relativity? Putting A New Model Of Quantum Gravity Under The Microscope

Echoes Of The Birth Of The Universe: New Limits On Big Bang's Gravitational Waves
August 19, 2009 — An investigation by the LIGO Scientific Collaboration and the Virgo Collaboration has significantly advanced our understanding the early evolution of the universe. Analysis of data taken from 2005 to ... > full story -
Vanquishing Infinity: Old Methods Lead To New Approach To Finding Quantum Theory Of Gravity
August 17, 2009 — Quantum mechanics and Einstein's theory of general relativity are both extremely accurate theories of how the universe works, but all attempts to combine the two into a unified theory have ended in ... > full story -
A Grand Idea About The Universal Universe
August 7, 2009 — Einstein succeeded only partly in explaining the aspects of the universe. Today's scientists are also at a loss about how it all connects. A mathematician in Norway and international fellow ... > full story
