Exploring Light’s Behavior in Time: A Review of Astrum’s “Light Can Go Backwards Through Time, And This Experiment Proves It” The video presents a groundbreaking study that redefines our understanding of light. Traditionally, light is known for its constant speed in a vacuum and its slower pace in mediums like glass or water. This video discusses an innovative 2023 experiment by Imperial College researchers, introducing the ‘time slit’ concept. This new take on the double slit experiment suggests light can travel at varying speeds, potentially even moving backwards in time. The video gets into the complexities of light’s interaction with time and space, challenging established physics principles and revealing light’s enigmatic nature.

Light’s Puzzling Nature and Speed Variations
Light has long perplexed scientists with its dual wave-particle nature, exhibiting different behaviors under observation and unobserved conditions. While light’s speed is a constant in a vacuum, it slows down in denser mediums like glass or water. This slowdown is due to light waves causing electrons in the medium to move, creating an overlapping wave that travels slower than the original light wave. Experiments have manipulated light’s speed dramatically, even slowing it to a halt under certain conditions.
The New, Time Slit Experiment
In 2023, researchers at Imperial College introduced a novel approach to the double slit experiment, using a material that could rapidly switch from transparent to reflective, creating a ‘time slit.’ This experiment revealed that when two laser pulses passed through these time slits in rapid succession, an interference pattern emerged, affecting the laser’s frequency. This pattern was akin to the intensity variations seen in the spatial double slit experiment.
Visualizing Light’s Journey Through Time
To understand this phenomenon, the experiment was visualized in a four-dimensional graph with space and time axes. This visualization suggested that light might be taking paths that involve traveling slower or faster than its known speed, potentially moving backwards in time. The experiment indicated that light always seeks the path of least time, even if it involves exploring routes through time itself.
Implications and Mysteries
This experiment suggests that light, in its quest to find the optimal path, might be ‘testing’ alternative routes through time, similar to how lightning finds its path. While we do not directly observe photons traveling from the future or at speeds slower than light without external factors, the interference patterns imply that light is exploring these possibilities. This discovery underscores light’s refusal to conform to established rules, presenting new mysteries for scientists to unravel.
