Somewhere else, you read this sentence and actually learned Spanish.
means A hypothetical reality existing alongside our own, where events unfolded differently from some branch point onward.
from 'Parallel' traces back to Greek 'parallelos' — 'para' (beside) plus 'allelos' (one another) — originally just geometry's word for lines that never meet. 'Universe' comes from Latin 'universum,' everything turned into one ('unus' + 'versus'). The phrase itself is a 20th-century graft from physics and science fiction: once quantum theory raised the possibility of branching realities, and pulp writers ran with it, 'parallel' stopped describing lines on paper and started describing whole worlds running alongside ours — close enough to imagine, far enough to never meet.
