I love this story. I'll give you the much abbreviated version. You can read the detailed version here --
Back in the mid 80's a physicist name Russell Humphrey's entered an informal contest with other scientists around the world. The goal was to predict the magnetic fields of Uranus and Neptune. The actual strength of the magnetic fields of these two bodies would be discoverd by Voyager 2 in the near future.
The scientists had to plug in two main variables to predict the magnetic fields of these two planets. One, they had to plug in the variable of what the planet was made of at its initial point of existence. The second variable the scientists had to plug in was how old the solar system was.
Scientists from around the world began making their predictions. They plugged in all kinds of stuff, mainly gases or metals, for the substance of the two planets, and of course, being almost unanimously evolutionists, they plugged in millions and billions of years for the age of the solar system.
Humphreys plugged in water as the substance of the two planets, and he plugged in an age of 6,000 years.
Voyager, as we all know, ultimately reached the two planets and transmitted back the data.
All the other scientists' predictions were not only off, but they were off by orders of magnitude.
Humphrey's predictions were a bulls eye. In other words, his predictions of the strength of the magnetic fields of Uranus and Neptune were right on the money.
Up until that time it was an accepted protocol that predictions were one of the very best tools for determining a scientific dictum.
This all changed with Humphrey's predictions. In short, Humphrey's predictions rocked certain sectors, and the relative scientific literature actually began to print and assert that, even though predictions IN THE PAST were considered one of the best tools for establishing scientific dicta, they were now no longer considered to be as important as they used to be.
In other words, when the prediction doesn't fit the dogma, throw it out.
And they still call themselves scientists!
