Zhang Nan

Academic, Chinese

Beijing-based UAP researcher known for AI-assisted acceleration analysis of declassified military footage

Background

Zhang Nan is a Beijing-based researcher specializing in unidentified anomalous phenomena (UAP) analysis and computational physics. He represents an emerging non-Western academic perspective on UAP data analysis, operating within China's broader scientific establishment focused on extraterrestrial phenomena and cosmic signals.

Notable Analysis

Zhang gained international prominence in 2026 when the US government declassified military UAP footage through the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE). He focused particular attention on a nearly five-minute infrared video captured by US military sensors in Florida in 2020, showing a humanoid-like aerial object hovering for an extended period before making an instantaneous displacement out of frame.

Acceleration Physics Research

Using AI-assisted computational analysis, Zhang investigated the physics of the object's observed movements. He concluded that if the movement represents an actual spatial displacement rather than a sensor artifact, the object's acceleration could have exceeded 600g—or 600 times Earth's gravitational force. This extraordinary acceleration profile places significant constraints on conventional aerospace propulsion theory and has drawn international scientific attention to the implications of observed UAP dynamics.

International Context

Zhang works within research networks connected to Zhang Tongjie, an astrophysicist at Beijing Normal University who leads teams using China's Five-hundred-metre Aperture Spherical Telescope (FAST) to examine cosmic signals as part of the search for extraterrestrial intelligence. His work bridges computational methods, military sensor data analysis, and civilian astronomy research.
