Gravity bends light. If gravity is too strong it bends light completely. Gravity bends (distorts) not only space, but space-time. This planetarium show is a friendly introduction to the General Theory of Relativity suitable for general audiences. You do not have to know what the local metricization of Riemannian manifolds are to appreciate the basis and the results of the General Theory of Relativity. Black Bubbles are the most extreme results of this theory; some people also call these black bubbles, black holes, but bubbles capture a better picture of the events horizon and what really goes on there. They are literally Gravity to the Max. By looking at something in its most extreme case facets that are not revealed in mundane application like normal falling motion on the earth are shown.
The infinite time dilation (time asymmetry) between an outside
the bubble observer and an observer who decides to visit the
bubble are explained. Some of the other weird properties of Black
Bubbles including resent observation of the vicinity of a black
bubble in the center of our galaxy will be shared with the
audience. Anyone with an inquiring mind and imagination of a
typical third grader can enjoy this planetarium show. Those few
people who do not want to flex (distort) or exercise (move) their
mind are advised to stay home and watch mindless television so
called reality shows, that are doubtless on at the same time on

a simulated view of a black bubble (hole) in front
of the Milky Way Galaxy. The black bubble is 10 solar masses so
its Schwarzschild radius, event horizion radius, is 30
kilometers, and is viewed from a distance of 600 kilometers
which is 200 Schwarzschild radii away and essentially Newtonian
gravity at this far distance of 600 kilometers from the
