Vast oceans, meteor craters, earthquakes and titanic continental collisions. The story of Tennessee is written in the rocks beneath our feet. Flip through the pages, and you're flipping through millions of years of time.
This week on Dialogue, host Brandon Hollingsworth and geologists Robert Hatcher and Harry Moore tell Tennessee's geologic story, start to finish.
The natural gas drilling method known as fracking is igniting controversy in states from Pennsylvania to Wyoming. Fracking is going on in Tennessee, too, and that has environmentalists concerned. This hour of Dialogue is dedicated to learning about the pros and cons of fracking in Tennessee. In the first portion of Dialogue, we hear from Dr. Kevin Hoyt of the University of Tennessee. He's heading up the university's efforts to study fracking on the Cumberland Plateau.
On this episode of Dialogue, Brandon Hollingsworth takes us boldly where no man has gone before. We discover the Final Frontier with a diverse and knowledgeable panel of experts. University of Tennessee Physics and Astronomy Professor Mike Guidry, UT researcher Linda Kah and Angela Quick of Maryville College discuss the prospect of life on Mars, new discoveries in cosmology and the observable universe, dark matter and dark energy and how to find what you're looking for when you gaze into the sky at night.
