Avi Loeb used a July Medium essay to discuss a preprint by John Birks that tries to explain some orb-like UAP reports without invoking unusual craft. According to Loeb's summary, Birks compared hundreds of orb reports in the National UFO Reporting Center database with American Meteor Society fireball records and argued that the timing correlation deserves study.
The proposed mechanism is an ionized, dusty plasma or cloud that might form after meteoritic material enters the atmosphere. Loeb described the idea as a testable natural model that could be compared with AARO-style orb data, including color, motion, duration and environmental context.
The hypothesis is relevant to UAP reporting because many public cases describe bright, round or slowly moving lights while providing little range or sensor context. A natural plasma model could explain some reports, but it would need stronger tests than a database correlation before being applied to specific military images or videos.
The archive treats the essay as a research lead rather than a settled explanation. It is useful because it offers a conventional pathway that can be falsified, especially for orb reports such as public military frames where size, range and motion are still uncertain.
