Max Planck, founder of quantum physics, has loosely been quoted as saying, "science advances one funeral at a time." Like all other endeavors, science is subject to peer pressure, which can influence publication reviews, academic appointments and grant approvals. But there's no such thing as settled science. Paradigm shifts do occur, as described by Thomas Kuhn in The Structure of Scientific Revolutions. Unlike postmodernism, science is based on objective experimentation and verification. No reputable scientist will ever claim to be in possession of eternal truth--it's a process more than an end result. Still, the consensus of practicing scientists (when there is one) is more likely to approximate reality than the wild musings of an Internet troll who--without evidence--claims that his latest theory will change everything.
