« Life on Mars: Hopefully It's Dead | Main | Laser Tag »


Laurel Kornfeld

Well, Mike Brown also brags about how he personally "reshaped the solar system." Please. Just because he says is too many doesn't make it so. He did not "kill" Pluto, as he loves to repeat ad nauseum. Only four percent of the IAU voted on the controversial demotion, and most are not planetary scientists. Their decision was immediately opposed by hundreds of professional astronomers led by Dr. Alan Stern, Principal Investigator of NASA's New Horizons mission to Pluto. Stern and like-minded scientists favor a broader planet definition that includes any non-self-luminous speroidal body orbiting a star. The spherical part is important because objects become spherical when they are large enough to be shaped by their own gravity--a characteristic of planets and not of shapeless asteroids. If that definition gives us 53 planets, so be it. The universe was not designed for our convenience. Several decades ago, people had to get used to the fact that there are billions of galaxies rather than one. Astronomers, kindergarten teachers, and everyone else can adapt to the fact that our soalr system does NOT have only eight planets.

Many theories talk about what to expect for 2012, I think most of us are wandering what is really going to happen, almost all of the ancient cultures knew about it, recorded for us to be ready for it.
