Episode 387 - Black holes dancing, colliding and third wheeling

July 13, 2020

Scientists have discovered the closet black hole to Earth, but relax it's 1000 Light years away. Ever felt like a third wheel, just be thankful it's not a black hole. A binary star system that can be seen with the naked eye with a lurking black hole. Super massive  black holes are hard to get your head around but can unleash tremendous energy. When two super massive black holes dance around each other, the fireworks are spectacular. Predicting when two black holes will graze past each other helps us refine our understanding of the universe.
