I don't know about all of that speculation, but you did give me a nice mental image of a barren, battle-scarred solar system littered with battleships containing black holes, ready to cause catastrophe at any moment, much like the nuclear wastelands of the Arctic.
- SapphireSun 10y agoThe black hole engines he's referring to glow very hot because they're very small, meaning that the surface of the hole is large compared with its volume. This allows for very bright hawking radiation if I understand correctly. If you stop feeding them they disappear within hours, years, or decades depending on how big they are.
- mtgx 10y agoYeah, black holes scare me, too. But to me it looks like the most "realistic" solution for travelling 10+ light-years. If we learn how to create cheap antimatter, we may be able to use that, too, but I'm not so sure if we could store that much on the ship for the roundtrip. A blackhole could last us a lot longer (I think around 100 light years, last I read about it - I don't remember the space ship's speed, but probably like 30% of light speed).
