They absolutely did not discover this, lol. Sure, the two post “erasure” signals each look like a Publication-Worthy Wave Distribution, but they sum to the original pre “erasure” signal. No time weirdness at all.
BREAKING🚨: Physicists discovered a quantum effect called retrocausality, where present choices seem to influence past events. In delayed-choice experiments, a particle’s behaviour appears shaped by measurements made after it travelled, as shown in Wheeler’s proposals and later tests like the delayed-choice quantum eraser. While it doesn’t enable time travel, it challenges cause-and-effect, sparking debate on how to interpret quantum mechanics and the deep interconnection of reality.
