Quantum Study Claims Light Can Exit Before Entering Material

The Spin
Narrative A
The experimental results demonstrate that negative time may not just be theoretical but could exist in a tangible, physical sense, representing a significant breakthrough in understanding quantum mechanics and how light interacts with matter. The measurements are solid and open new avenues for exploring quantum phenomena, even if practical applications remain unclear.
Narrative B
The term "negative time" is misleading and has nothing to do with actual time passage — it simply describes how photons travel through a medium and how their phases shift. The phenomenon can be explained through conventional quantum mechanics without requiring new interpretations about the nature of time.
