100 Years of GR, 20 years of GGR: Looking back and looking forward

We celebrate the anniversary of 100 years of general relativity and 20 years of the APS topical group on gravity by discussing two of the energizing topics in gravity today: the quests to detect gravitational waves and to quantize gravity. The panel takes a look forward and back to address where we stand on these pivotal issues, how we got here and where we are going.
