For centuries unexplained lights have appeared in the night sky with no suitable theory though many have been advanced. A New Zealander is claiming he was the first to successfully explain the mystery lights commonly called "UFOs" with a unified theory. These are the hard-to-explain UFO cases. Author and researcher Peter Coleman has revealed the real science behind these unexplained UFO fireballs. His unified theory not only explains these UFO chariots of fire but in one sweeping theory ball lightning, the Tunguska "meteor", the Kaikoura UFOs, the Australian Min mins, the will o' the wisp and several other events are accounted for. Not content with theory he has actually created the fireballs in the laboratory and published the results in a 1999 Spring issue of EOS Transactions a publication of the American Geological Union. His theory first appeared in 1993 in Weather (publication of Royal Meteorological Society of the UK) and in New Scientist 22 May, 1999. He has since written two books Ball Lightning-a scientific mystery explained (limited edition) that challenges the idea that ball lightning is an unsolved problem especially the book by Mark Stenhoff called Ball Lightning- an unsolved problem. Peter's latest book is Great Balls of Fire-A unified theory of UFOs, ball lightning, Tunguska and other anomalous lights is expected to be available sometime this year.
