A groundbreaking experiment suggests that photons of light can seemingly exit a material before entering it, exhibiting a negative time delay within a cloud of chilled atoms. This bizarre quantum phenomenon challenges our understanding of time and the nature of light.
For the first time, physicists have created a one-dimensional gas made entirely of light, a groundbreaking achievement that could unlock new insights into the quantum behavior of photons. This new state of matter, dubbed a photon gas, was created by firing a laser into a reflective container filled with dye, causing photons to cool and condense. This research could lead to discoveries of previously unknown quantum optical effects.
