Professor Richard Hammond has published numerous scientific articles in a wide range of fields, from general relativity to quantum mechanics, and has pioneered a new theory of gravitation that has won international acclaim. He has won awards from NASA for his research and teaching, international awards for research on gravity, and was invited to Cal Tech's Jet Propulsion Lab to study solar system tests of Einstein's theory. Dr. Hammond brings the fascinating world of physics to the public. He is an Adjunct Professor at the University of North Carolina at Chapel Hill and works for the Army Research Office as a theoretical physicist.
Theoretical physicist Dr. Richard Hammond discussed his new book The Unknown Universe, which explores mysterious aspects of cosmology and space. Cosmic acceleration, he explained, is the accepted concept that the universe is in a constant state of expansion, like a balloon being blown up.Galaxies, like pennies on the balloon, are moving further and further apart.Yet conversely, local perturbations dictate that some galaxies will collide with each other, such as the eventual merging of our own Milky Way with neighboring Andromeda. Hammond speculated that puzzling 'dark energy' could be the force that is causing the universe to expand-- it's even possible that our universe could be contained in another universe, contributing to the expansion, he conceded. The observation of the hypothetical Higgs Particle (referred to by some as the God Particle) could be the greatest breakthrough in science, he said. It would help explain how particles have mass. He also suggested th ... More »Host: George Noory
