Mass, Diameter, and Schwarzschild
By: Gijs Bellaard
I recently watched the entertaining Kurzgesagt video titled This Black Hole Could be Bigger Than The Universe. In this video it is stated that the observable universe its mass and diameter are such that it (technically) can be classified as a black hole! Indeed, one definition of a black hole is any massive object whose radius is smaller than its Schwarzschild radius. I was interested in visualizing this fact by plotting the mass and diameter of various objects. The result is the following Python Script and figure below.
