Latest General relativity Stories
Black holes are voracious monsters at the center of galaxies that shape the growth and death of the stars around them with their tremendous gravitational pull and explosive ejections of energy. Now, researchers are using them as a tool to probe the limits of spacetime.
On today’s Your Universe Today podcast, theoretical physicist Dr. Kelly Holley-Bockelmann is back to discuss facts about black holes and help us separate myth from reality.
In this podcast, Dr. John Millis spoke with Vanderbilt's theoretical physicist Kelly Holley-Bockelmann about how stars die and black holes form.
A popular theory that emphasizes dark energy as a contributor to the acceleration of the universe’s expansion does not fit newly obtained data with regards to one fundamental constant – the proton to electron mass ration – claims a University of Arizona astronomy professor.
Two of the greatest scientific achievements of the last century were the establishment of the theories of Quantum Mechanics and General Relativity, yet the two theories seem to be at odds with each other.

The Woodward effect is one of many effects that can be derived from the framework of general relativity. The mathematics can be somewhat opaque and so it can be difficult to determine if the resulting effect is a physical, or purely mathematical construct.
NASA is pursuing a pioneering technology capable of atomic-level precision to detect gravitational waves or ripples in space-time caused by cataclysmic events, including the Big Bang itself.
Astronomers, using the Keck Observatory, have found the star they need to test Einstein's theory about the fabric of space-time.
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...
