Darkness doesnât involve waves because itâs a lack of electromagnetic waves. If you define the speed of dark to be the speed at which you could find out about someone turning out the lights, itâs exactly the same as the speed of light: 671 million mph, or 2.99 x 108 m/s, or about 1 foot per nanosecond.
Fastest Thing Recorded In modern physics, light is regarded as the fastest thing in the universe, and its velocity in empty space as a fundamental constant of nature. The speed of light in a vacuum is presently defined to be exactly 299,792,458 m/s (about 186,282.397 miles per second). Thatâs basically the fastest thing the human species has ever experienced today. If you travel around the earthâs equator at the speed of light you will travel around the entire planet earth 7.4 times in approximately one second.
