Looking At Quantum Gravity In A Mirror
2012-03-21 04:10:14

Einstein's theory of gravity and quantum physics are expected to merge at the Planck-scale of extremely high energies and on very short distances.

A new experiment proposed by physicists at the National Institute of Standards and Technology (NIST) may allow researchers to test the effects of gravity with unprecedented precision at very short distances—a scale at which exotic new details of gravity's behavior may be detectable.

A team led by Princeton University scientists has tested Albert Einstein's theory of general relativity to see if it holds true at cosmic scales.

Sloan Digital Survey data provide test that rules out alternative theories of gravity.

While airplane and rocket experiments have proved that gravity makes clocks tick more slowly – a central prediction of Albert Einstein's general theory of relativity – a new experiment in an atom interferometer measures this slowdown 10,000 times more accurately than before, and finds it to be exactly what Einstein predicted.

Does an exciting but controversial new model of quantum gravity reproduce Einstein's theory of general relativity?

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 failure.

When the world's most powerful particle accelerator starts up later this year, exotic new particles may offer a glimpse of the existence and shapes of extra dimensions.

There is no attractive gravitational force between matter. Gravitation is based on a repelling force. Gravitation arises from particle pressure towards matter.

Two Canadian researchers at the Perimeter Institute for Theoretical Physics suggest that the motion of galaxies in a distant cluster is more easily explained by a Modified Gravity (MOG) theory than by the presence of dark matter.

Classical and Quantum Gravity
2012-05-12 20:18:16

Classical and Quantum Gravity is a peer-reviewed journal published by IOP Science. As of May 2012, the editor-in-chief is Clifford M Will (Washington University, St. Louis). The journal covers all aspects of gravitational physics and the theory of space-time. It scope includes: Classical general relativity, Applications of relativity, Experimental gravitation, Cosmology and the early universe, Quantum gravity, Supergravity, superstrings and supersymmetry, and Mathematical physics relevant...

String Theory -- A string theory is a physical model whose fundamental building blocks are extended objects (strings, membranes and higher-dimensional objects) rather than points. String theories are able to avoid problems, such as infinite energy density, associated with the presence of mathematical points in a physical theory. The term 'string theory' properly refers to both the 26 dimensional bosonic string theories and to the 10 dimensional superstring theories discovered by...
