Another poster who pretends to be knowledgeable but doesn't know how to spell prominent scientists' names, in this case Wegener's. You don't even have patdolan's excuse that this is a foreign name for you. > > His name was Ott-Christoph Hilgenberg and his book had the title 'Vom > wachsenden Erdball' (only available in German). It may have been a credible theory in 1930, but 93 years have passed since then. According to Wikipedia, "the theses of Ott Christoph Hilgenberg and Nikola Tesla were based on absorption and transformation of aether-energy into normal matter". Hmm. Do you believe in aether-energy? > > He was a geologist of the university of Charlottenburg (now part of Berlin). > > (btw: I spent most of my time at TU-Berlin in the very same building as > Hilgenberg.) So? I did my doctoral work in the very same building as William Perkin Jr. Big deal, but it doesn't make me cite Perkin's ideas as gospel truth. -- athel -- biochemist, not a physicist, but detector of crackpots
