Impacts Large and Small and Very Large

From a human-made crater (well, spacecraft-made) on an asteroid, to the Moon-forming impact, to an accelerating pace of black hole merger detections, the astroquarks survey the latest news in astronomical collisions. The asteroid Apophis has a close date with Earth in 2029, and what episode of Walkabout would be complete without some general relativistic frame dragging? Zoe Landsman joins us while Charm quark Addie Dove is off launching things into space! Plus space news and a historical/avengical trivia.
