The Demotion of Pluto

Lileks sums up:

In the end, however, the decision was made and forgotten.

The planets continued their elegant gavotte, heedless of the names mere humans gave them. People were reminded once again that science is not a fixed thing, but a malleable, evolving set of ideas that adapts to new challenges.

Intelligently designed as our science is, we must always keep a skeptical view. One day string theory explains everything; the next day string theory falls from vogue like narrow lapels or rockabilly, and another theory explains this wondrous cosmos.

In the end, Pluto is a warning, a cautionary tale. Many things we believe may turn out not to be so, after all.

Except for man-made global warming. Only an idiot doubts that one.
