I’m creating a hard sci-fi setting for my novella, which takes place about 500 years in the future.

As I want the setting to be as realistic as possible, I want to avoid the sci-fi trope of having dark energy or dark matter being the generic “superweapon” etc.

If dark energy and/or matter could be harnessed, what could they be used for? (weapon? material? energy source? FTL travel?) Some assumptions can be made, as the sciences and technology have advanced 5 centuries.

  • $\begingroup$ If you're looking for inspiration, scienceblogs.com/startswithabang/2008/04/15/… has some information to get you started, but the boffins in the comments there, although a decade old, still have no sensible, reasonable assumptions about the true application, as the true definition hasn't been found yet. How 'true' do you need your scientific fiction? $\endgroup$ – Gray Roberts Oct 3 '18 at 11:55
  • $\begingroup$ I'd want the tech, that uses one or both of those, to have some basis/plausibility in science. (Vs simply making up a random "death ray" and calling it a "dark matter beam"). From what I understand, dark matter/energy has some interactions with gravity, but not with normal matter, so using it as a weapon seems impossible etc. $\endgroup$ – bluet Oct 3 '18 at 13:10

    $\begingroup$ The problem with this question is that scientists disagree on what dark matter and dark energy actually are. We just know they have to exist because of the way galaxies move. There are several theories in the astrophysics community regarding what they could be, but none were proven so far. But if you do some research on your own you might find some theories about dark energy and/or dark matter which might have interesting storywriting material. $\endgroup$ – Philipp Oct 3 '18 at 19:34
