Back in the 1960s and '70s, I was fond of painting pictures based upon ideas which most scientists then thought were just wacky.

In 1978, I came across a hypothesis which was considered to be so unorthodox at the time that it caused great amusement within the Scientific Establishment. That hypothesis was called 'The Greenhouse Effect'. 99% of our scientists then thought that it was an utterly stupid idea.

Today, 99% of our scientists think that it is utterly accurate. That is in the nature of scientific inquiry. As new facts emerge, new (and hopefully) better hypotheses and theories are developed.
