QUOTE:
Let's be finicky in our application of the phrase. For example,
Newtonian physics did not get sent to Pluto. It was shown to be a
valid approximation of Einstein's relativistic physics for objects
moving well below the speed of light, and as such was incorporated
into the newer theory. And cold fusion, N-rays, Velikovskian planet
billiards and similar crackpottery weren't sent to Pluto either
because they never enjoyed a significant period of acceptance by the
scientific community (perhaps they all reside on another planet... Uranus?).
