enough terrifying things about black holes
In the video above, Kurzgesagt outlines how a sufficiently advanced civilisation could extract energy from a black hole. It wouldn’t be easy, cheap or safe, but the science is there.
And if you can get energy from a black hole… well, you can guess where this is going:
There’s an even better way to get energy from a black hole and oddly enough, it builds the biggest bomb any living the could ever hope to build: the black hole bomb.
What’s a black hole bomb exactly? Well, much like you’d build a Dyson sphere around a star to harness its energy, you could theoretically construct a giant mirror ball to contain a black hole.
Then, you’d remove part of the mirror, shoot electromagnetic waves inside and let them bounce around for a while. Combined with the rotational power of the black hole, you’d eventually get quite a bang:
A supermassive black hole would release as much energy as a supernova, making the bomb the largest explosion any living being could ever release.
The good news is, it doesn’t have to explode — you could use it as an near-endless source of power. Just remove a part of the mirror from time to time and harness the energy of the bouncing wave.
Dibs not having that job.
