The Princes in the Tower: A Disappearance Inside a Succession Crisis

The princes probably died after entering the Tower of London, and Richard III had custody and benefited politically. The surviving evidence supports suspicion, not a proved murder method or uniquely identified culprit.

Folklore & Legends

The Vanishing Hitchhiker: Anatomy of a Travelling Legend

Vanishing-hitchhiker stories are documented folklore rather than one verified recurring event. Their changing details, local authentication and older supernatural motifs reveal how a modern legend acquires credibility.

Scientific Anomalies & Natural Phenomena

Tabby’s Star: Deep Dips, Citizen Science and the Dust Question

Tabby’s Star is a genuine astronomical anomaly discovered through citizen science. Chromatic dimming supports small-particle dust rather than an opaque alien structure, while the dust’s origin remains unsettled.

Frederick Valentich: A Last Radio Call Over Bass Strait

Frederick Valentich’s recorded radio exchange is evidence of what he reported, not of what caused the disappearance. Disorientation, misidentification and accident remain plausible without recovered wreckage.
