| May 3, 2016 at 17:32 | comment | added | Hypnosifl | If you want to build "structures" on the surface of a neutron star, it's possible that the nucleons that make it up can form structures analogous to molecules, see here--some science fiction writers have speculated about life forms made of such materials, and there are also speculations about "femtotechnology" which would be even smaller than nanotechnology, see my answer below for a speculation on how this might be possible in Earthlike conditions. | |

They have reasonably plausible explanations of building objects with incredible strength and compactness with magnetic monopoles. Everything from ringworlds to wormhole forges to millimeter-sized spaceships. orionsarm.com/eg-article/48630634d2591 | |

| May 2, 2016 at 23:35 | comment | added | IchabodE | I don't think antimatter is the best example, because anti-particles will form into large scale structures precisely the same as regular matter, only exactly opposite. For example, there is anti-hydrogen out there with the same old atomic weight and covalent bonds as regular hydrogen. Now I'll shut up and let you get on with the spirit of your question... | |
