There was a saying during the height of the "flower power" revolution of the late 1960s: "speed kills." Of course at that time the cliche was referring to amphetamines but if the news out of Germany bears up, a group of physicists has surpassed the "speed limit" for light and thus negated the underlying "constant" of Einstein's concept of the physical laws of the universe.
Einstein's theory of "special relativity" actually states the general case whereas the theory of "general relativity" is about a particular situation. Confused? Good, then you are in the right frame of mind to start thinking about modern physics...believe me it gets sooooo much more weird from here.
The revolutionary idea is that all aspects of time and space in the universe are always to be understood "in relation" to each other. When it is said that a train is traveling at 30 mph (don't worry there are no other trains or passengers in this word problem...) it is always a statement which has validity in the context of some frame of reference, say against "static "frame of the earth. Of course if the frame is the Milky Way, that same train is moving much faster; if the frame is another train, it may be slower.
You intuit this. Remember being on a train or subway pulling out of a station at the same time that the train on the next track is moving too. Your train may appear stationary or much quicker than it would had there been no other train next to it. Your train may seem to move backward if that next door train starts moving and yours does not -- and you have no other way to establish an other "third" frame.
Bottom line-- there is, to Einstein's physics no "objective" reality. Hold on...but I said that there was a constant that these German scientists have messed with recently. Right. OK, there IS one thing in the universe that is outside of these relative measurements-- the speed of light, or to use its Einsteinian abbreviation: "c" (You remember E=mc(squared) ).
"c" is 299,792,458 meter/second or 186,000 miles/second..now there have been ideas that the speed can be slower due to friction in non vacuum spaces and in the bizarre world of teeny tiny quantum mechanics...ok, in quantum no one the hell knows...but in the rest of the physical universe it was like the fact that my old man would be ripping mad if I was out after curfew...you could bank on it.
The fact that there is this one constant makes the rest of the theory make mathematical sense. Without it, it's back to the drawing board.
Now, of course, some wise ass will always ask, "What makes light so damn special, eh? Why is it the single constant in the universe." I dunno and neither did Einstein. What is more he didn't much care. It worked, and that was good enough. Of course, if these German physicists are corroborated, those wise ass questions will be a bit more prescient than generations of physics 101 professors would like to admit.
I suppose, it's open season in theoretical physics again. Anyone got any bright ideas?
