Those who corrupt the science for political gain want everyone to think it is more complicated than it actually is.
Here it is, in a nutshell: The logic of science boiled down to one, essential idea. It comes from Richard Feynman, one of the great scientists of the 20th century
As usual, Feynman is correct. If your theory’s prediction do not agree with experiments then your theory is wrong.
Climate Change “Science” is the most obvious example of a theory that fails the Feynman test. But, while less widely recognized, HIV equals AIDS also fails that test.
As a general rule whenever the science is declared “settled” you can be assured that is neither settled nor science.
