• Cosmic Information Theory and Analysis: IT from BIT, from BITs in IT 

      Bond, J. Richard (Georgia Institute of Technology, 2011-11-30)
      We consider the Universe to be fundamentally quantum and statistical, the many-paths/many-worlds story. This lecture uses Cosmic Information Theory and Analysis, CITA, as a unifying theme to explore the vast sweep of our ...
    • Dark Chocolate: Dark Matter or Dark Energy 

      Ludovice, Peter J.; Hunt, William D.; Oluseyi, Hakeem (Georgia Institute of Technology, 2009-06-03)
      Join our guest Hakeem Oluseyi from the Department of Physics and Space Science at the Florida Institute of Technology in discussing cosmology from dark matter to dark energy and the importance of diversity in physics. ...
    • Dark matter, and how we would not be alive without it 

      Abel, Tom (Georgia Institute of Technology, 2012-08-30)
      Most of the mass in the Universe is of some unknown form of matter. While we have some guesses what it might be we are not sure. In this talk for a non-specialist audience, Professor Abel will explain how observations using ...
    • The metric of the expanding universe 

      Wetzel, Christian Klaus Carl (Georgia Institute of Technology, 1978-12)
    • The Origin of the Universe and the Arrow of Time 

      Carroll, Sean M. (Georgia Institute of Technology, 2016-04-11)
      One of the most obvious facts about the universe is that the past is different from the future. We can remember yesterday, but not tomorrow; we can turn an egg into an omelet, but can't turn an omelet into an egg. That's ...
    • Surveying the Accelerating Universe with Supernovae 

      Jha, Saurabh W. (Georgia Institute of Technology, 2012-03-05)
      In 1998 two rival teams of astronomers studying exploding white dwarf stars, called type Ia supernovae, came to the surprising conclusion that the expansion of the Universe is speeding up. This discovery of "the accelerating ...
    • What Happened Before the Big Bang? 

      Bojowald, Martin (Georgia Institute of Technology, 2013-04-08)
      The standard model of cosmology suggests that the universe started with a phase of very high density, described by general relativity as a singularity. Quantum gravity attempts to resolve the singularity by a more fundamental, ...
