How and Why We Try to Observe Gravitational Waves
Ζωντανή μετάδοση στις 20 Νοε 2015
One hundred years ago this month, Albert Einstein revolutionized our
understanding
of gravity: space and time were no longer a passive stage on which the
universe evolved, but instead a dynamic participant.
Perhaps Einstein's most fascinating prediction are gravitational waves,
disturbances in spacetime that are generated by cataclysms such as the merger of two black holes.
Scientists
are on the cusp of making the first direct detection of these waves
using ground-based interferometers and are making the first steps
towards building gravitational wave observatories in space. These
efforts promise to usher in an entirely new field of astronomy.
Join
+Tony Darnell+Alberto Conti and Harley Thronson along with guests Shane
Larson (Adler Planetarium/Northwestern University), Joey Shapiro-Key
(University of Texas), and Ira Thorpe (NASA Goddard) for a discussion of
the science and technology behind gravitational waves and the
instruments used to observe them.
