Slowing down light
Webb1 feb. 2024 · In a vacuum like space, the speed of light is just over 186,280 miles per second. Scientists have now shown it's possible to slow it down to zero miles per … Webb20 aug. 2024 · Light is slower when travelling through a gas medium such as an atmosphere. However, the difference in speed between a vacuum and an atmosphere such as ours is practically negligible. You would need a very special medium such as a Bose-Einstein condensate to really slow down light (its speed falls to 17m/s in such a medium).
