Show Notes
When regular run-of-the-mill black holes spiral into a deathly embrace, a gravitational chirp spreads across the universe, but when the behemoths in galactic centers merge, they cause a low rumble in space-time. Scientists are using nature's free ultra-precise astronomical clocks - pulsars - to hunt for this rumble. Closer to home the Earth has a new very-very-mini-moon, and the astroquarks face multiple energy-related trivia questions.
