In yesterday’s (3/27) Zippy strip, our Pinhead recognizes a dark service window in a generic roadside fast food place as an astronomical black hole:
(#1) Zippy between two worlds, ordering food in space
Two things: the service window; the black hole.
The service window. Dark and inscrutable, as in Zippy’s experience:
(#2) Service through the window (image adapted from a Yahoo Style Canada photo)
An actual (definitely fancy) service window:
(#3) RENLXFI brand commercial vertical sliding window for restaurant kitchen service, food truck, or mobile snack cart (from Amazon, in various sizes, roughly $300-350 per window)
The black hole. From Wikipedia:
A black hole is an astronomical body so compact that its gravity prevents anything, including light, from escaping. Albert Einstein’s theory of general relativity, which describes gravitation as the curvature of spacetime, predicts that any sufficiently compact mass will form a black hole. The boundary of no escape is called the event horizon. In general relativity, crossing a black hole’s event horizon traps an object inside but produces no locally detectable change. General relativity also predicts that every black hole should have a central singularity, where the curvature of spacetime is infinite.
