Bell’s equations (or Bell’s inequalities) are asking the question: can the universe be both real and local at the same time?
realism means things have definite properties whether we look or not, and locality means nothing can influence something else faster than light. Bell showed that if both of these were true, certain mathematical limits — his inequalities — should hold. But quantum mechanics just doesn’t play by those rules; experiments keep showing those inequalities being violated.
So, if we want to keep quantum mechanics and its built-in indeterminism, we have to give up either locality or realism (with locality being the one we’d probably rather let go of over realism).
That means the world isn’t purely objective or neatly separated in space – it’s non-local. Before measurement, everything exists as a kind of probability wave , only as a spread of possibilities waiting to collapse into something real.
