Thinning Atmosphere Explains Flying Dinos - Dr. Donald Pettit, NASA Astronaut

Astronaut Donald Pettit champions a theory he developed while
studying under Octave Levenspiel at Oregon State University. In
short, it is apparent that large winged dinosaurs could not fly
under today's atmospheric conditions. Pettit suggests that the
solution to dino-flight is that the Earth's atmosphere was much
thicker in the past, lending buoyancy to the giant animals while
maintaining today's ratios of elemental composition. If this
trend is extended long before the dinosaurs we end up with a
hypothetical atmosphere as thick as Venus or even more. The
theory then raises the question: what events caused the
atmosphere to disappear?

PODCAST INFO:  Anastasia completed her PhD studying
microbial communication at Columbia University. When not talking
to brilliant people or making movies, she spends her time
painting and exploring the woods. Michael Shilo also did his PhD
at Columbia studying the elastic properties of molecular water.
When he's not in the film studio, he's exploring sound in music.
They are both freelance professors at various universities.
