Scientists Use Neutrons To Search For Dark Energy
2014-04-17 10:13:42

Vienna University of Technology With neutrons, scientists can now look for dark energy in the lab All the particles we know to exist make up only about five per cent of the mass and energy of the universe. The rest – "Dark Matter" and "Dark Energy" – remains mysterious. A European collaboration led by researchers from the Vienna University of Technology has now carried out extremely sensitive measurements of gravitational effects at very small distances at the Institut Laue-Langevin...

Pixidis researcher Tom Whitney of Minneapolis has achieved the Holy Grail quest of modern physical science: the discovery of Einstein's famed unified field equation. Sought by thousands of scientists around the world, this equation reveals the ultimate blueprint running the universe. Minneapolis, MN (PRWEB) January 03, 2014 The unified field equation theorized to exist by Einstein has been discovered—uniting hundreds of years of multidisciplinary science in a single, historic fell...

A new physics paper published on Open Access Peer Reviewed Journal “Science and Education Publishing” titled “SR Equations without Constant One-Way Speed of Light” examines two postulates of Special Relativity and concludes that the claim of “constant one-way speed of light” contradicts itself. Deerfield, IL (PRWEB) September 23, 2013 Science and Education Publishing Journal’s editor team displayed extraordinary intellect and courage to challenge the widely accepted theory...

Modified Gravity Theory Predicts Galaxy Dynamics

John P. Millis, PhD for redOrbit.com - Your Universe Online For decades astronomers have studied the motions of galaxies – their rotations about their axes, as well as their interactions with each other – and been puzzled by what they have observed. The data suggests one of two possibilities: either these galaxies, and the space between them, contain significantly more mass than what is seen, or our physical understanding of gravity is flawed. The oft-discussed solution is that...

Testing Einstein In Outer Space
2013-01-09 05:42:49

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Two of the greatest scientific achievements of the last century were the establishment of the theories of Quantum Mechanics and General Relativity, both of which have withstood continual experimental scrutiny. However, a problem remains. The two theories seem to be at odds with each other. Researchers, for decades, have sought a theory that would combine the two realms — the large-scale gravity fields, and the...

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. At this scale, new phenomena could arise. However, the Planck-scale is so remote from current experimental capabilities that tests of quantum gravity are widely believed to be nearly impossible. Now an international collaboration between the groups of Caslav Brukner and Markus Aspelmeyer at the University of Vienna and Myungshik Kim at Imperial...

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.Of the four fundamental forces that govern interactions in the universe, gravity may be the most familiar, but ironically it is the least understood by physicists. While gravity's influence is...

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. And, after two years of analyzing astronomical data, the scientists have concluded that Einstein's theory, which describes the interplay between gravity, space and time, works as well in vast distances as in more local regions of space. The scientists' analysis of more than 70,000 galaxies demonstrates that the universe -- at least up to a distance...

Sloan Digital Survey data provide test that rules out alternative theories of gravity An analysis of more than 70,000 galaxies by University of California, Berkeley, University of Zurich and Princeton University physicists demonstrates that the universe "“ at least up to a distance of 3.5 billion light years from Earth "“ plays by the rules set out 95 years ago by Albert Einstein in his General Theory of Relativity. By calculating the clustering of these galaxies, which stretch...

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...
