Latest General relativity Stories
At the beginning of each year, master of ceremonies for the science website Edge.org John Brockman asks his cadre of world-renowned thinkers to reply to a single question of eminent significance.
Sensors destined for ESA’s LISA Pathfinder mission in 2014 have far exceeded expectations, paving the way for a mission to detect one of the most elusive forces permeating through space – gravity waves.
A team of scientists has used the NASA/ESA Hubble Space Telescope to observe a quasar accretion disc — a brightly glowing disc of matter that is slowly being sucked into its galaxy’s central black hole.
The unification of quantum mechanics and Einstein's general relativity is one of the most exciting and still open questions in modern physics.
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.
New measurements have confirmed Albert Einstein's general theory of relativity after an experiment last week brought the theory into question.
Measuring at the limits of the laws of nature – this is the challenge which researchers repeatedly take up in their search for gravitational waves.
Astronomers have discovered a pair of white dwarfs spiraling into one another at breakneck speeds.
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, Australia and India will drastically increase the expected rate of detection.
NASAâ€™s Gravity Probe B (GP-B) has produced astonishing new confirmation of two key predictions derived from Albert Einstein's general theory of relativity, which the spacecraft was designed to assess.
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...
