A Local SETI–Femtosecond Photonics Hypothesis for Hessdalen UAPs: Stealth Extraterrestrial Probes Emitting Atmospheric Laser Filamentation

To the point

A locally minded SETI-inspired theory argues that a stealth extraterrestrial visitation probe in Earth orbit emits invisible beams that, when they hit air, create ultrafast laser filaments and two visible forms of luminous UAPs (a narrow, single-bullet cone and a wider, scanning, multi-pulse type), which together explain Hessdalen sightings, with probabilities based on the Drake equation and notes on uncertainties and ways to test against Hessdalen data.
