Physicists confirm 'negative time' is real by asking the atoms themselves
SMRTR summary
Physicists confirmed "negative time" is real — meaning light appears to exit an atom cloud before entering — by measuring atomic excitement levels during photon transmission. After averaging 1 million test runs over 70 hours, atoms themselves reported negative transit times, validating earlier experiments and revealing yet another strange behavior of quantum physics.
