The rotating black hole has been described as one of nature's most perfect objects. As described by the Kerr solution of Einstein's gravitational field equations, its spacetime geometry is completely characterized by only two numbers "” mass and spin "” and is sometimes described by the aphorism "black holes have no hair.'' A particle orbiting a rotating black hole always conserves its energy and angular momentum, but otherwise traces a complicated twisting rosette pattern with no...

During the next decade, a delicate measurement of primordial light could reveal convincing evidence for the popular cosmic inflation theory, which proposes that a random, microscopic density fluctuation in the fabric of space and time gave birth to the universe in a hot big bang approximately 13.7 billion years ago. Among the cosmologists searching for these weak signals will be John Carlstrom, the S. Chandrasekhar Distinguished Service Professor in Astronomy & Astrophysics at the...

In a move that would have any astrophysicist scratching his head, the U.S. Defense Intelligence Agency (DIA) commissioned a report to assess whether gravitational waves could threaten national security. The JASON Defense Advisory Group was also asked to investigate other potential applications for high-frequency gravitational waves, such as imaging the Earth's core or uses in telecommunications. Gravitational waves are wrinkles in space-time caused by the movement of objects with...

Combining a double natural "magnifying glass" with the power of ESO's Very Large Telescope (VLT), astronomers have scrutinized the inner parts of the disc around a supermassive black hole 10 billion light-years away. They were able to study the disc with a level of detail a thousand times better than that of the best telescopes in the world, providing the first observational confirmation of the prevalent theoretical models of such discs. The team of astronomers from Europe and the US studied...

A team of theoretical and experimental physicists, with participants from Case Western Reserve University, have designed a new black hole simulator called BlackMax to search for evidence that extra dimensions might exist in the universe. Information about BlackMax's creation has been published in Physical Review Letters in the article, "BlackMax: A Black-Hole Event Generator with Rotation, Recoil, Split Branes and Brane Tension." Black holes are theorized to be regions in space where the...

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
2004-10-19 04:45:42

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...
