Draft version March 7, 2023 Typeset using LATEX default style in AASTeX631 PHYSICAL CONSTRAINTS ON UNIDENTIFIED AERIAL PHENOMENA Abraham (Avi) Loeb1 and Sean M. Kirkpatrick2 1Head of the Galileo Project, Astronomy Department, Harvard University 60 Garden Street, Cambridge, MA 02138, USA 2Director of All-domain Anomaly Resolution Office 1010 Defense Pentagon Washington DC 20301, USA ABSTRACT We derive physical constraints on interpretations of “highly maneuverable” Unidentified Aerial Phenomena (UAP) based on standard physics and known forms of matter and radiation. In particular, we show that the friction of UAP with the surrounding air or water is expected to generate a bright optical fireball, ionization shell and tail - implying radio signatures. The fireball luminosity scales with inferred distance to the 5th power. Radar cross-section scales similarly to meteor head echoes as the square of the effective radius of the sphere surrounding the object, while the radar cross-section of

Two days ago, my world changed.  It all happened on twitter.  I have been researching the UFO and more recently, UAP disclosure and event history for thirty years. All along the way I have believed we are being visited. What I learned over this period of time was gleaned from materials oft researched and presented in bombastic, and over-the-top ways. Alien abductions, crazy encounters that seemed, let’s face it, phony as hell. Far too farfetched to be anything but fanciful nut cases looking for attention. I have always been one to be highly skeptical. Let’s face it, the past ten or so years have launched a myriad of people that care only for notoriety and could care less about facts. My mind works on facts. From everything I have seen, heard, and researched, I was convinced we were being visited. I truly thought the government(s) were hiding crashed UFOs, UAPs – I don’t know what to call them at this point. Spaceships. Let’s go with that, though that isn’t entirely correct- I’ll get to
