About Adam G. Riess

Sarah was great to work with for the first links for the contract, and once passed on to Edie, the same great service continued. Definitely easy to work with both. When came the time to talk to Adam, he was very easy to talk to and understand his demands (a/v wise). At the conference, Adam was VERY patient with the technical difficulties we had. It was very appreciated and definitely will be recommending him and your company to others. Thank you once again.

Supernovae and the Discovery of the Accelerating Universe

In 1929 Edwin Hubble discovered that our Universe is expanding. Eighty years later, the Space Telescope which bears his name is being used to study an even more surprising phenomenon, that the expansion is speeding up. The origin of this effect is not known, but is broadly attributed to a type of "dark energy" first posited to exist by Albert Einstein and now dominating the mass-energy budget of the Universe. I will describe how our team discovered the acceleration of the Universe and why understanding the nature of dark energy presents one of the greatest remaining challenges in astrophysics and cosmology.
