antiworld
Matter's mirror cosmos
Antiworld is a hypothetical universe composed entirely of antimatter, the mirror image of our matter-based cosmos.
In physics, if matter and antimatter meet, they annihilate each other in a burst of energy—so an antiworld would be cosmically incompatible with ours.
Figuratively, antiworld describes any realm that operates by opposite principles: Her childhood home felt like an antiworld to the life she'd built.
