Today, I received an interesting new preprint (available here) from Professor John Birks with the following accompanying message:

“Dear Prof. Loeb,

I greatly appreciate your recent work on Unidentified Anomalous Phenomena (UAPs) and wanted to give you a preprint (attached) of a paper I have submitted to Atmospheric Chemistry and Physics proposing an explanation for UAP orbs and possibly daytime objects, e.g., “flying saucers,” as well.

In this paper, I review hundreds of orb sitings reported on the National UFO Reporting Center (NUFORC) website and find that orb observations are highly correlated with meteor fireball observations reported on the American Meteor Society website (better than 99% confidence). This led me to develop a theory of orbs based on the properties of meteor dust. The theory can explain virtually all the behaviors of orbs. And, importantly, daytime orbs are expected to look like solid objects — like flying saucers for example.

I am a Professor Emeritus at the University of Colorado Boulder and an atmospheric chemist best known for co-developing what became known as the “nuclear winter” theory with Paul Crutzen in 1982. The theory was further developed and given its name by Carl Sagen and colleagues the following year. Paul went on to win the Nobel Prize in Chemistry in 1995 for his work on the ozone layer. My work has spanned theoretical chemistry, laboratory measurements of reactions responsible for the “ozone hole,” field measurements of air pollutants, and development of new measurement techniques for chemical species in general. As founder of 2B Technologies, I led a team that developed a new generation of air pollution monitoring instruments, so I am also very interested in your project to monitor UAPs as well.

I would be happy to discuss my paper with you at your convenience. I believe it can explain a large fraction of UAP sightings.

All the best,

John
