Just wanted to provide notice that I am only responsible (in part) for the last version I edited; see User:Hillman/Archive. I emphatically do not vouch for anything you might see in more recent versions, although I hope for the best.
Good luck in your search for information, regardless!---CH 00:02, 1 July 2006 (UTC)

text: It seems likely that a comprehensive physics will be emerging in a few decades, as the survey of the Solar System reaches a globally plausible consensus.  Remaining in particular are the manned ventures beyond the Earth-Moon system, the New Horizons survey of the Plutonian system, and the results from the big new telescopes.  This is a good section, merely somewhat early to identify a Golden Section in relativity theory.  Patience is a virtue in Wikipedia. SyntheticET (talk) 17:32, 26 September 2012 (UTC)
thread_title: Students beware

message: On 2011-7-9, an anonymous contributor added two publications by Ruffini to the timeline. As far as I can see, the time-line is supposed to show historical developments, not merely list people's individual publications, unless those publications are truly famous and ground-breaking. So I think these publications should be removed. If everyone adds their favourite publications, the list would contain tens of thousands of articles.

message: Was the Kruskal-Szekeres coordinate system not introduced in 1960 and by George Szekeres not Peter Szekeres (his son)? Check the reference in Hawking and Ellis - but perhaps someone knows better than them? —Preceding unsigned comment added by 132.181.7.1 (talk) on 04:33, 17 December 2006 (UTC)

message: The title of this article, "Golden age of general relativity", is not capitalized correctly, and thus it does not hyperlink readily to other Wikipedia articles. For example, really important theories in the sciences are proper nouns and their names get capitalized. For example: Newton's Laws of Motion, the Theory of Universal Gravitation, Atomic Theory, Special Relativity, General Relativity, the Theory of Evolution by Natural Selection, Modern Algebra, Complex Analysis, Matrix Theory, Vector Analysis, Quantum Mechanics,Freudian Psychology, etc.
Furthermore, the term "Golden Age" is capitalized, such as in the Golden Age of Greek civilization, the Golden Age of the Roman Republic, etc.
Hence, this article should be titled the Golden Age of General Relativity. Other forms of capitalization can be redirected to this one.

replies: text: Further note - it is readily apparent from this interview with Ezra (Ted) Newman that exceptional progress was made in  the field of general relativity between (roughly) 1960 to 1975. In addition, this was preceded by some kind of GR awakening in Europe and U.S in the 1950's. So there are hints that something special  happened during these time periods (the 1950's and 1960 to 1975). I am now thinking that a section in the "History of general relativity" article should be a broad accounting of this "renaissance" of general relativity - not just about black hole research. Furthermore, this supports what User:TimothyRias was saying in the WP:PHYS thread. Also, the problem of the irreconcilability of quantum theory (quantum mechanics) with general relativity, and the burgeoning science of detecting gravity waves is part of this time period. Here is the book related to this interview ---- Steve Quinn (talk) 06:49, 12 November 2010 (UTC)

message: *Constellation of Sagittarius, in the direction of the center of the galaxy. That center – building up and out of the galactic disk – is tightly packed with stars.  regions of this so-called "bluge" the first to take notice was the physicist Karl Jansky back in the 1930s.He was asked by his employer, Bell Telephone Labs, to investigate sources of static that might interfere with what it saw as sthe killer app of its time... radio voice transmissions. Using this ungainly radio receiver... jansky methodically scanned the airwaves. he documented Thunderstorms, near and far and another sinal he could not explain. It sounded like steam – a hiss of radio noise. Jansky narrowed it to a spot in the constellation of Sagittarius, in the direction of the center of the galaxy.Located within a larger pattern of radio emissions So Jansky's sighting would become known as Sagittarius A*. It was the 1960s and astronomy, like society was in a period of ferment. Startling new observation was being made and new interpretations were in the air. Quasars had just been discovered. Extremely bright beacons of light from deep space. Were they comming from the centers of distant galaxies? To study an event at the center of a galaxy, you have locate it. Young Becklin first took aim at our neighboring galaxy, Anedromeda. In ultravioled light, you can see a dense glow in the middle. Becklin found the point where the light reaches peak intensity and marked it as the Center. From our orientation in space, the entire Andromeda galaxy is in full view. But our galaxy is a different story. We live inside it, of course. Becklin had to find a way to see through all the dust and gas that obscure our line of sight into the center. So he went to a military contractor and obtained a device that reads infrared light, whose wavelengths are similar to the distances between particles in a dust cloud, allowing them to move right through. Becklin began measuring the brightness of the light as it rose to a peak, marking the location of the galactic center. Pinpointing this site would now allow astronomers to begin probing for details with a new generation of powerful telescopes, to peer into the bright lights. the forbidden zones, deep in the heart of the Milky Way. A few years later, in 1993, high atop Hawaii's Mauna Kea volcano. There were many problems, The American and German groups shared the same goal. to pinpoint the precise location of Sagittarius A*, and find out what it is. Because the object is too small to see at 26,000 light years away they would study it by tracking the orbits of starts around it. They tracked gas whipping around its center, figuring its speed at three million miles per hour, which led them to calculated the mass of whatever occupied M87's center at some 4 billion times that of our Sun. Their measurement – first-ever of its kind point to the presence of a Black Hole of truly super massive proportions. Searching Center, in search of clues to the origins and evolution of our galaxy. The Chandra X-ray space observatory recorded high energy radiation mostly likely given off by Ultra-dense neutron stars and small black holes. 20, 0000 black holes inhabit the inner three light years of the galactic center. In the last no other single object is known to weigh that much, its strong evidence of but it's still not iron clad proof.

thread_title:  Constellation of Sagittarius 

message: The one reference in this article that actually refers to a golden age is that by Kip Thorne; and he calls it the "Golden Age of black hole theory". Is the term widely used or is it just his invention? A Caltech site discusses a Golden Age of General Relativity, but it was produced by the group that Kip Thorne is a part of. A couple of other references (A to Z of Physicists and The Expanding World of General Relativity) appear to be quoting Thorne.  Other people seem to have different ideas. This paper defines a golden age lasting from 1915 to 1925. In Introduction to General Relativity, Walecka says "Ours might truly be called the golden age of general relativity and cosmology." (i. e., around 2007).  RockMagnetist (talk) 21:18, 20 March 2013 (UTC)
replies: text:  Yet another reference claims the golden age started when Kerr found a solution for rotating black holes in 1963. The term only gets 18 hits on Google Scholar. Some of the hits are from festschrifts, where contributors feel a need to wax rhapsodic about the history of the subject. I have never heard the term personally, and it doesn't seem to be in widespread use or have a canonical time frame. --Mark viking (talk) 21:54, 20 March 2013 (UTC)
replies: text:  It is not well defined. Well, I have seen one or another definition. But does it matter? The term is well-known among relativists, even if nobody has bothered to pin down exactly when it begun or ended. Don't remember where I read it, but the term refers to a period of time when GR was unusually "productive". People had finally learnt how to use it and experimental data became available.
