Twitter thread: "The Romulans were doing it right after all"

Harnessing tiny rotating singularities as a source of energy, that is.

Did you know you can get power out of a black hole? It turns out that black holes can function as mass-energy converters, thanks to angular momentum & frame dragging.

Read the full Twitter thread here. It's pretty neat - the concept is called the Penrose process.

I did know that but then I studied General Relativity at university back in the 70s. The black hole could also be given an electric charge so that it would be a lot easier to control its position using electric and magnetic fields.

would you say the author on Twitter presented things pretty accurately (albeit simplified)?

the idea that this could be an explanation for hypervelocity ("rogue"?) stars is also pretty fascinating

The summary seems to be accurate. Of course, if the black hole is charged the spacetime metric is a bit different from a Kerr metric. The Kerr-Newman metric is then appropriate.

Don't give me ideas; I might defect to the Romulan Star Empire after this.
