FOX Nation host Abby Hornacek takes a closer look at the topics and buzz words you find your friends and coworkers using to sound intelligent. Each week Abby and her expert guests will tackle topics we take for granted and help to explain the roots and meanings behind them.

This week Paul M. Sutter, a research professor in astrophysics at the Institute for Advanced Computational Science at Stony Brook University and a guest researcher at the Flatiron Institute, joins Abby in the classroom to help with her lesson plan. Paul discusses the history of UFOs, how UFOs are studied and recorded, and what we should know about popular UFO theories, and hypotheses.
