It won't work either, but at least you don't need a black hole for it. :) | |
| Apr 25, 2019 at 21:10 | comment | added | Kelly S. French | This answer triggered a thought I couldn't help but share. The concept of an Alcubierre warp drive requires said 'exotic matter', so is it theoretically possible to take advantage of this to jump-start a warp drive? Or is this not the same type of exotic matter / energy? | |

| Apr 25, 2019 at 17:38 | comment | added | Sidney | Pop-sci theorizing here, but is "exotic matter" actually necessary to balance this equation? If a virtual matter-antimatter pair self-instantiates and the anti-matter particle falls into the black hole while a regular-matter-particle escapes, shouldn't it annihilate a "particle's" (yes, I know black holes are weird™ and black hole particles aren't really a thing, that's why it's in quotes) worth of matter from the black hole, or has the black hole essentially forgot that it's constituent mass used to be composed of matter? | |
