Origins Of Black Holes: Gravity At Its Extreme


Origins Of Black Holes: Gravity At Its Extreme


Description:

Dr. Feryal Özel, Associate Professor, Astronomy/Steward Observatory, University of Arizona. Presented March 1, 2011. Gravity is the most important force in the universe, holding together planetary systems, stars, and galaxies. It is what makes the stars hot enough to shine and what keeps the Earth close enough to the Sun for life to form. It is also what ends the life of every massive star with a spectacular collapse and the formation of a black hole. Finding and studying hundreds of black holes within the Milky Way and in other galaxies brings us closer to understanding gravity at its extreme. Cosmic Origins is the story of the universe but it's also our story. Hear about origin of space and time, mass and energy, the atoms in our bodies, the compact objects where matter can end up, and the planets and moons where life may flourish. Modern cosmology includes insights and triumphs, but mysteries remain. Join the six speakers who will explore cosmology's historical and cultural backdrop to explain the discoveries that speak of our cosmic origins. http://cos.arizona.edu/cosmic/
