You’ve heard of quantum entanglement, probably. Two particles linked in some strange way, regardless of the distance between them. But I’d never heard that this could happen through time too:

The data revealed the existence of quantum correlations between ‘temporally nonlocal’ photons 1 and 4. That is, entanglement can occur across two quantum systems that never coexisted.

Honestly, I understand very little of this. It doesn’t make me very confident about the Instagram videos I’ve idly scrolled through. But it does highlight just how limited the human perspective is. See also The colour of the inhuman world.
