Gravitational waves
In Part 1 of this presentation, physicist Wal Thornhill began his analysis of the recent award of the Nobel Prize in Physics to scientists for their contributions to the so-called detection of gravitational waves. While science media has shown exactly zero skepticism of the gravitational waves pronouncements, Thornhill discussed some of the foundational mathematical problems that preclude the claimed detection of "two black holes colliding a billion years ago, and producing ripples in the fabric of space-time."

Today, in Part 2, Thornhill explores another fundamental cosmological question, and that is the existence of the required medium for the communication of waves in a vacuum - a medium called the aether.
