parallel universe
Coexisting separate dimension
A parallel universe is a hypothetical self-contained reality coexisting with our own, often imagined as branching from different outcomes of the same events.
In physics and cosmology, the concept appears in multiverse theories.
In everyday speech, it describes radical disconnection from shared reality: We must be living in parallel universes if you think that meeting went well.
