All very relevant points to why human generation ships are unlikely. Totally irrelevant points as to why, out of the hundreds of billions of planets in the Milky Way, it would appear that not one has evolved an organism capable of spreading out of its gravity well. In general, Life Finds A Way. Life on a ship is depressing? You may as well argue that life in hydrothermal vents would be boring.
As for Dyson spheres, don't take the remark so literally. I simply meant that a galaxy-spanning slime mould would probably be visible to our physics, somehow. Life is an entropy engine. Once it gets going, it really gets going. But we appear to live in an improbable oasis in a vast desert.

And who says no life evolved "capable of spreading out of its gravity well"? > As for Dyson spheres, don't take the remark so literally. Of course it should be taken literally, because all of this is all about what the laws of nature do and don't allow and the practicalities surrounding that. This isn't an class or discussion about what does and doesn't make a good sci-fi story. And what is a "galaxy-spanning slime mould" even? > Life on a ship is depressing? You may as well argue that life in hydrothermal vents would be boring. Yes, it would be. There is no intelligent life living near thermal vents. What an odd thing to say.
- defrost 2y agoThat's a damning indictment of the inhabitants of Hjalteyri. Is this perhaps a specific personal grudge against your hometown or a more general dislike of Icelanders? https://en.wikipedia.org/wiki/Hjalteyri https://en.wikipedia.org/wiki/Hjalteyri https://xray-mag.com/content/strytan-diving-icelands-hydrothermal-vents https://xray-mag.com/content/strytan-diving-icelands-hydroth...
