A 50-year-old theoretical process for extracting energy from a rotating black hole finally has experimental verification.
Using an analogue of the components required, physicists have shown that the Penrose process is indeed a plausible mechanism to slurp out some of that rotational energy — if we could ever develop the means.
That’s not likely, but the work does show that peculiar theoretical ideas can be brilliantly used to explore the physical properties of some of the most extreme objects in the Universe.
