Strange quantum experiment shows “negative time” is more than an illusion

This fascinating quantum experiment reveals that photons can actually exhibit what seems like negative time when passing through a cloud of rubidium atoms. Imagine a photon arriving at its destination before it even enters the cloud – how wild is that? Researchers have been curious about this phenomenon for decades, and now they've taken a deeper look into what really happens during this process. By querying the atoms, they aim to understand the true nature of this 'negative time' and challenge previous assumptions about it.
