I have just figured out where all that invisible dark matter we need to make the universe work is. It is stuck between theoretical physicists ears when they write pseudo-science books based on no evidence what so ever. Everyone complains about quackery of "alternative medicine" but theoretical physics takes junk science to a new level. The lips are moving but the brain isn't working. Dark Matter and Dinosaurs, the Cosmic Anthropological Principle, Many Worlds ...
Seems that John Gribbin got the same message from the book. We definitely have gone from Dark Matter to doesn't matter.
