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. #JWST Wing Deployment: http://www.nasa.gov/feature/goddard/james-webb-space-telescope-wings-successfully-deployed Links to Shane's blog and videos on GW: Behind the Curtains of the Cosmos 1: Inflation and the Microwave Background http://wp.me/p19G0g-kX Also, Shane's YouTube GR videos: http://tinyurl.com/sllGRvideo Shane's GR Centennial blog posts, that has GW stuff: http://tinyurl.com/grCentennial The GW Specific posts from the GR Centennial posts: http://wp.me/p19G0g-w5 and http://wp.me/p19G0g-wA CMB Polarization (Sean Carroll): http://www.preposterousuniverse.com/blog/2014/03/16/gravitational-waves-in-the-cosmic-microwave-background/ LISA Pathfinder Summary: http://www.esa.int/Our_Activities/Space_Science/LISA_Pathfinder_overview #astronomy #space #technology #gravitationalwaves #cosmology
