David de Hilster

David de Hilster is a physics crank and a notorious Internet proponent of autodynamics.

He founded NeWiki ("An Encyclopedia For a New World") in 2007 after his original research had repeatedly been removed from Wikipedia. The wiki only has a couple of hundred pages, quickly assembled and then left as a ghost wiki until it finally disappeared in 2016. The wiki was not open to outside editors and listed two other committee members: Matthew Stroul and Travis Brainbridge. Apparently, he establishes and then abandons ghost sites quite a bit.

Qualifications
He has a bachelor's degree in mathematics with a minor in architecture and a master's in computational linguistics. Note the absence of physics qualifications. He also makes films.

Expanding Earth
Not content with just one crackpot theory, de Hilster has also gone on to advocate the perhaps even-more-ridiculous expanding earth hypothesis: "200 million years ago, the earth's continents were all together on a much smaller orb and since then, the earth has been growing significantly."
