Hacker News Reader

Thanks for reminding me I needed to blog about why I think Hawking radiation drives aren’t really as good as they look: https://kitsunesoftware.wordpress.com/2022/05/14/no-a-black-...

(I agree that Isaac Arthur’s channel is good).

The paper you linked, https://arxiv.org/abs/0908.1803, is also a fun read.

We could throw garbage or nuclear waste into it

From the article: "if the black hole’s temperature is high, the radiation is composed of all elementary particles, photons, electrons, quarks, and so on. It’s really unhealthy. And a small black hole converts energy into a lot of those particles very quickly. This means a small black hole is black basically a bomb."

The nuclear waste thrown into it may be much cleaner than the stuff it will throw back out.

True, but that's tunable, the bigger it is the less comes out.

Also a great (short) one by Kurtzgesagt
