Two supermassive black holes are locked in an orbital dance at the core of the distant galaxy OJ 287. This diagram shows their sizes relative to the solar system. The larger one, with about 18 billion times the mass of our sun (right), would encompass all the planets in the solar system with room to spare. The smaller one is about 150 million times the mass of our sun (left), which would be large enough to swallow up everything out to the asteroid belt, just inside the orbit of Jupiter.
Wasn’t there a simulation, that shown it will work? Provided we somehow obtain insane amount of energy or exotic matter.
Not sure. All I’ve heard is that it’s still theoretically possible.
