Benson's 4-D House of Pancakes (not to be confused with BENSON'S 3-D HOUSE OF PANCAKES) is a hypothetical structure that in modern physics serves as a model for the so-called "universal theorem" that unifies the 4 basic forces and explains time, space, and reality as we know it. The 4-D BHOP was first proposed in 1999 by renowned astrophysicist Stephen Hawking, and scientists generally agree that it is by far the best model for explaining the known universe. The House is a physical building that serves pancakes, and exists perpetually through all of time on the space-time continuum.
