Time could be ‘negative’ as photons observed leaving a material before entering it
SMRTR summary
Scientists observed photons exiting a material before entering it, suggesting the existence of "negative time" in quantum interactions. This groundbreaking experiment with ultracold rubidium atoms challenges our understanding of atomic excitation and could influence future quantum research, though it doesn't affect our everyday experience of time.
