The rule could be anything, as funny or as serious as you want. The universe will progress in a similar way that it has up until this point, unless your changed rule prevented it from doing so.

Some examples might be:

  • The invention of currency is not allowed.
  • Iron is slightly less stable.
  • The Ancient Greeks are able to cultivate Silphium, which does not go extinct now.

Nothing is explosively combustible. Gunpowder is inert, oil is just a lubricant. No guns, no gasoline.

The stars are using fusion, not combustion though, right?

[–] SendMePhotos@lemmy.world 1 points 4 months ago (3 children)

Isn't fusion how we get bombs? Or is that Fission... I forget.

Fusion makes a bomb like the sun.

Fission makes a bomb like chernobyl.

Seems similar, actually different. We're actually pretty good at fission, but fusion is way harder. The problem with fusion is that you need a huge amount of power to generate a slightly huger amount of power in return, and we are pretty crap at generating a big enough spike of energy to start the reaction and marginally worse at capturing said power after. All in all, pretty far away from practical fusion power.

Fission, by comparison, can happen when you have too many special minerals in a wrong shaped pile. We abuse this effect to boil water, and use that boiling water to make power.

We don't have fusion yet. Once we do, it should solve a lot of energy demands.

[–] LordGimp@lemm.ee 3 points 4 months ago

Nah we definitely have fusion, just not for anything other than bombs.

Fun fact: to set off a fusion reaction, hydrogen bombs actually have a smaller fission bomb inside it. Sometimes multiples of fission-fusion reactions all stacked inside of eachother like nesting dolls.

[–] WanderingVentra@lemm.ee 1 points 4 months ago* (last edited 4 months ago)

I believe both. Fusion bomb was made after the fission one. So ya, that's a tough one.

But I suppose as long as we're just making wishes, there's got to be one like things can't explode but you can still get harmless energy from them or something like that, so stars still work. Idk,this one might require a physicist to phrase it right lol.
