Pseudophysics

The world is crammed with people who think they have The Big Idea That Will Shake Physics, and being unable (or unwilling) to get it published in a scientific journal try to make it known via the Net - much cheaper than publishing a book at one's own expenses (although some do this anyway). Needless to say, most of these ideas are based on gross ignorance or misunderstanding of physics, the scientific method, or both.
