- maratd 7y agoAlso Winter World (and the other two books in the trilogy). Fun read. Very similar in style to the The Expanse.
- ismail 7y agoPersonally I found the style very different between the expanse and the three body problem trilogy. The expanse seems “lighter” or less hard. The last book, deaths end i found to be particularly “hard sci-fi”.
- maratd 7y agoWrong trilogy =) I was talking about https://smile.amazon.com/gp/product/B07N32K12H/ref=ppx_yo_dt_b_d_asin_title_o08?ie=UTF8&psc=1 https://smile.amazon.com/gp/product/B07N32K12H/ref=ppx_yo_dt...
- xvector 7y agoJust a tip - forest has one ‘r’ :)
- ncmncm 7y agoThe Dark Forest is a related idea, in which mature civilizations are not all destroyed by contact with their equals, but lurk about, in ambush. The mutual demolition alternative seems simpler and more reliable, and possibly more consistent with the evidence. Dropping a black hole, even a smallish one, into a star would seem to eliminate the central pressure needed to sustain fusion, and turn it off pretty suddenly, by astronomical timescales.
- skykooler 7y agoDropping a black hole into a star would actually cause its power output to increase; the radiation from matter accreting onto the black hole provides sufficient power to prevent the star's collapse. See https://en.wikipedia.org/wiki/Quasi-star https://en.wikipedia.org/wiki/Quasi-star for more details on the physics.
- ncmncm 7y ago"Such a star would have to be at least 1,000 solar masses..." Although, it doesn't really make sense. Like a puncture in the wall of a pressure vessel, the pressure at the event horizon would be zero. It is hard to see how an accretion disc could form in pure plasma at such density. The fluid dynamics of plasma under such conditions is entirely intractable, so it is also hard to believe in any claimed solution. But temporarily multiplying the output of a star might work just as well to eliminate a pesky alien infestation.
- ncmncm 7y agoReading the paper, it appears they treat the plasma as a gas, relying on acoustic pressure interactions that don't happen in a plasma. If I understood correctly, and that is conventional practice in calculations about black hole accretion discs, there is a great deal of nonsense published on the topic.
