How is Pluto Not a Planet?
Pluto was always a planet the issue is that since recently the astronomers had been wisely enough working without any conventional definition of what a planet was. Now that they have dared to define it they have really screwed up. But as they know well that bad news and controversy is better than no news and since Einstein the astronomer have been belittled by the molecular phisicists who were defining what was and was not going on in the universe, they were fed up of being ignored and it was a good way to get noticed. They have succeded, now we know why they should not receive a single buck to look for black matter and black holes which they have not found after so many years. Specially after the theory of relativity porved that anyone who looks at the sky and stars, because of the speed of light might be looking at objects which do no exist anymore and have disappeared long ago, yet for humans they all share (existing and non existing) a simultaneous space/time (we call it the sky).
