Interested in science? Want to learn more about the latest technology breakthroughs in normal English, minus the jargon? Then Café Scientifique Pittsburgh at Carnegie Science Center is the place to be!
Café Sci is THE place in Pittsburgh where anyone interested in science can get together at a scientific hub to discuss today's science issues with experts, and best of all... you can ask your own questions! After a brief talk by our monthly guest speaker, the evening is dedicated to a question-and-answer session. Plus, enjoy our pub-type atmosphere with food and drinks available for purchase.
Dr. Arthur Kosowsky
Professor of Physics and Astronomy
University of Pittsburgh
Arthur Kosowsky, a top expert in cosmic microwave background (CMB) radiation, will speak about a new discovery made using the BICEP telescope at the South Pole earlier this year. A team of physicists noticed a subtle change in the CMB, which is hypothesized to be the result of gravitational waves by a sudden cosmic expansion during the very earliest moments of the universe. Despite the buzz this discovery has generated, more analysis is needed to determine whether the signal is evidence of the first moments of the universe, or whether it has a much more local source – such as dust grains in our own galaxy, aligned by magnetic fields. More data will be required to determine the cause of the change. If the signal is indeed from the first moments of the universe, it opens a remarkable window into physics at a scale we will never be able to probe with experiments on Earth, and it can tell us what happened when the universe was a trillionth of a trillionth of a trillionth of a second old.
Kosowsky will talk about the science behind these ideas, what kinds of observations need to be done to decide the source of what we are seeing in the microwave sky, what this might tell us about the universe, and what kinds of future physics experiments and theories it might prompt.
Arthur Kosowsky is a professor of Physics and Astronomy at the University of Pittsburgh. He received his PhD in physics from the University of Chicago in 1994 and has been on the faculty of Pitt since 2005. He is the author of many scientific papers about the universe, and particularly how the cosmic microwave background radiation tells us about the properties of the universe and about fundamental physics. He is also a member of the Atacama Cosmology Telescope (ACT) project, which has built a custom-designed 6-meter microwave telescope with superconducting bolometric detectors to observe the microwave sky from the Atacama desert in the Chilean Andes.
