In the realm of physics, the speed of light is considered one of the most fundamental constants in the universe, dictating the structure of time and space as we know it. But what if this cornerstone ...

(Reuters) - The Italian professor who led an experiment which initially appeared to challenge one of the fundaments of modern physics by showing particles moving faster than the speed of light, has ...

Scientists have long known that the speed of light can be slowed slightly as it travels through materials such as water or glass. However, it has generally been thought impossible for particles of ...
