Transcript of ADAM RIESS
Adam Riess, an astrophysicist and professor from Johns Hopkins University, won the Nobel Prize in 2011 for his work on "Dark Energy." His work is primarily in measuring exploding and pulsating stars. NASA has identified his most recent work on dark energy as the #1 Achievement of the Hubble Space Telescope to date. (7)
GETTING TO KNOW DR. RIESS
Born 1969 in Washington DC as the youngest of three children, Dr. Riess grew up with an inquisitive mind. He attended MIT and later Harvard where he graduated with a doctorate in astrophysics. As a fellow at UC Berkeley, he was able to mathematically explain the expanding universe which he described as "remarkable." He later married his wife Nancy in 1998 which he described as an "even more exciting event." He continued working on various projects and had a daughter, Gabrielle, in 2006. That same year, he moved to Johns Hopkins where he began the research that eventually led to the idea of "dark energy." (1)

Dr. Adam Riess
Utilizing the Hubble Space Telescope, Dr. Riess and his colleagues attempt to explain dark energy by measuring two variables: its evolution in supernova rates and recent equation of states. They do this by measuring supernova stars which are viewed extremely far away. This requires mathematical calculations that are way beyond the scope of understanding for this class. The standard deviation of the telescope are current obstacles in this research. (5)
Dark energy is the term used to describe the force that is causing the accelerated expansion of the universe. Not much is known about its properties. IT'S A MYSTERY GIVEN THE NAME DARK ENERGY. Researchers estimate that the universe is 68% dark energy. What we can see with all the tools we have only actually makes up about 5% of the total universe. (6)
The Mysterious.. DARK ENERGY
Who Funds His Work?
Johns Hopkins University and the Space Telescope Science Institute in Baltimore, MD. These are his major contributors!
Prior to Dr. Riess' research, astrophysicist had theorized that the universe was decelerating in its growth. This publication in the Astronomical Journal presented their findings that the universe was in fact expanding and accelerating due to forces pulling on it. These forces were given the name "dark energy." (8)
Summary of Segment
1998-Saw the universe was not slowing down as expected, but actually speeding up
Everywhere there is space is some "dark energy"
Verified that there is virtual particles that flip into and out of existence
Use supernova stars to measure these quantities
The ideas behind dark energy may be similar and fit into Einstein's theory of generativity or it may be that this has broken the theory.
ESSENTIALLY: THIS DISCOVERY MAY LEAD TO COMPLETELY NEW PRINCIPLES OF PHYSICS!
As previously stated, NASA claims this as the #1 biggest advance using the Hubble Telescope. This research is ground breaking and could put forth entirely new physics principles. Besides being one of the most respected scientists in his field (and others), he has appeared on NPR, CBS, National Geographic, and so many more.
He has given lectures on the subjects at Johns Hopkins, Shaw Prize Lecture, and Scientific American conferences. (9)
The main findings of his research show that the universe is accelerating due to a pulling force acting on it. Dr. Riess equated this finding to throwing you keys in the air and them not coming back down but accelerating the opposite direction. It contradicted much of the previous theories on this subject, mainly that the earth was decelerating. (Science Friday Segment)
