Explaining Black Holes in Five Ways

Research astronomer Varoujan Gorjian (whose team at NASA is called Structure of the Universe Group) explains Black Holes to five different individuals whose understanding exists at five different levels: a five-year old, a teenager, a grad student studying astronomy, and an expert. In the fascinating video for WIRED, super-personable Gorjian begins by explaining how gravity works and ends up discussing low-luminosity active galactic nuclei. While our understanding of the fascinating phenomenon varies, this video is sure to uncover some cosmic facts—and in an accessible manner. Learn more at WIRED.
