SHOCK AND HORROR AND VARIABLE SPEED OF LIGHTA few years ago Einstein's hypnotists found it suitable to make some more money by challenging Einstein's principle of constancy of the speed of light:http://www.prospect-magazine.co.uk/article_details.php?id=5538Paul Davies: "Einstein's famous equation E=mc2 is the only scientific formula known to just about everyone. The "c" here stands for the speed of light. It is one of the most fundamental of the basic constants of physics. Or is it? In recent years a few maverick scientists have claimed that the speed of light might not be constant at all. Shock, horror! Does this mean the next Great Revolution in Science is just around the corner?"The "maverick scientists" created various "Variable Speed of Light" theories, became famous, got enough money and of course there was no Great Revolution in Science around the corner. So now there are no shock and horror in Einstein's cult and the selfsame Paul Davies can happily return to the original idiocy based on Einstein's false principle of constancy of the speed of light:http://www.asuwebdevil.com/issues/2007/02/23/news/699963"For this prof, it's only a matter of time.....Davies said an object traveling at a given speed experiences time slower relative to a stationary object. The faster the object moves, the slower it experiences time, he said. If a man traveled at 99 percent the speed of light for a certain amount of time to a point in space, then turned around and came back, he would find people on Earth aged years more than he did."There is another reason why relativity hypnotists experience so much happiness now. The "maverick scientists" managed to discredit the true principle of variability of the speed of light (c'=c(1+V/c^2) or c'=c+v) that Einstein himself introduced when he did not know how else to explain the gravitational redshift. So when one tries to explain that the speed of light is variable the standard reaction is something like this: "What? Variable speed of light? Magueijo's theory? That is not serious!"Pentcho Valevpvalev@yahoo.com
I understand that existing, generally accepted accepted relativity theory does indeed allow for light propagating, in vacuo, at various different speeds if gravitation is present; but that at any one point of observation light passing that point would always appear, to an observer located there, to have the universally recognized constant speed of light (2.9.....x10^8 m/sec). It is very important, when discussing how light or anything else behaves, to carefully state the situation of the observer, and also the situation of the object being observed, and to state whose measuring instruments are being used to describe the relationship between the observer and the thing observed. When light is said to move at a certain speed, we need to ask, as seen by whom, and as measured by what instruments? If these things are not clear, all kinds of nonsense will result.
