Light waves move through both time and space. In the theory of special relativity, which was formulated by Albert Einstein, it is established that the speed of light in a vacuum is constant and is denoted by "c" (approximately 299,792 kilometers per second). This theory indicates that light propagates through both spatial dimensions and the dimension of time.
According to special relativity, space and time are intertwined in a four-dimensional construct known as spacetime. Light waves travel through this spacetime, and their motion is described as a trajectory through both spatial and temporal dimensions.
It is important to note that light waves travel at the maximum possible speed in spacetime, which is the speed of light "c." As light moves through space, it also experiences the passage of time. This behavior is captured by the concept of "time dilation," which states that as an object (or in this case, light) approaches the speed of light, time slows down relative to an observer who is at rest.
Therefore, light waves indeed move through both time and space, interacting with and being influenced by both dimensions as they propagate.
