Latest General relativity Stories
NORTON SHORES, Mich., Jan. 8 /PRNewswire-FirstCall/ -- Horizon Group Properties, Inc. (Pink Sheets: HGPI), announced today that it has sold minority interests in the entities that own five of its outlet centers to Bright Horizons of South Florida, LLC ("Bright Horizons").
Within a decade scientists could be able to detect the merger of tens of pairs of black holes every year.
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 contribution to a frontier area of basic physics.
Does an exciting but controversial new model of quantum gravity reproduce Einstein's theory of general relativity?
An international group of scientists says it has defined the energy density of gravitational waves created immediately after the birth of the universe.
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.
Microscopic objects floating in fluids move great distances at times, not just in a bell curve, disputing an Einstein theory, a U.S.
Xiang Zhang, a faculty scientist with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and professor at the University of California Berkeley, lead a study in which it was determined that the interactions of light and matter with spacetime, as predicted by general relativity, can be studied using the new breed of artificial optical materials that feature extraordinary abilities to bend light and other forms of electromagnetic radiation.
An astrophysics experiment in America has demonstrated how fundamental research in one subject area can have a profound effect on work in another as the instruments used for the Laser Interferometer Gravitational-Wave Observatory
In his discussion of accelerated motion on page 60 of The Meaning of Relativity, Albert Einstein made an approximation that allowed him to develop the theory of relativity further.
Nature Physics is a peer-reviewed scientific journal established in 2005 and published monthly by the Nature Publishing Group. The editor-in-chief is Alison Wright, who is a full-time professional editor employed by the journal. The journal publishes original research, letters, full-length articles, review articles, news, views, physics research highlights, commentaries, book reviews, and correspondence. The main focus is pure and applied physics research, encompassing core physics...
General Relativity and Gravitation is a peer-reviewed scientific journal published monthly since its establishment in 1970. It is published by Springer on behalf of the International Society on General Relativity and Gravitation. G.F.R. Ellis and H. Nicolai are the editors-in-chief. The journal covers modern gravitational physics, encompassing all theoretical and experimental aspects of general relativity and gravitation. The journal’s main goals include public outreach through teaching...
Foundations of Physics is a monthly-published journal devoted to the conceptual bases and fundamental theories of modern physics and cosmology, emphasizing the logical, methodological, and philosophical premises of modern physical theories and procedures. The journal publishes results and observations based on fundamental questions from all major fields of physics: quantum mechanics, quantum field theory, special relativity, general relativity, string theory, M-theory, cosmology,...
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...
Spacetime -- In special relativity and general relativity, time and three-dimensional space are treated together as a single four-dimensional manifold called spacetime (alternatively, space-time; see below). A point in spacetime may be referred to as an event. Each event has four coordinates (t, x, y, z). Just as the x, y, z coordinates of a point depend on the axes one is using, so distances and time intervals, invariant in Newtonian physics, may depend on the reference frame of an...
