Episode 65: Rethinking the Rules of Reality

The fundamental forces of the universe are often still a mystery to scientists.

UA Science Lecture Series: Rethinking Reality spot The University of Arizona College of Science presents "Rethinking Reality," a series of 5 lectures exploring our world and ourselves. AZPM will livestream these lectures Mondays at 7 p.m. from Jan 30 - Mar 6, 2017. (PHOTO: UA College of Science)

LISTEN

Modern physics is dramatically changing our understanding of the world around us. In the first lecture of the 2017 College of Science public lecture series, Dr. Keith Dienes, Professor of Physics, takes us on a tour through some of the most revolutionary new ideas in physics. Describing what is known about fundamental forces of the universe, he sets the conceptual stage for a series of presentations that will cover topics from gravitational waves traversing the astrophysical universe to weird counterintuitive features of the fundamental building blocks of the natural world. He leaves us with the striking recent discovery that all of known matter constitutes only about 5% of all the energy of the universe - forcing the realization that there are huge discoveries still to be made.
