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.
Light travels at a speed of 186,000 miles (299,338 Km) a second or 700 million miles (1,126,540,800 Km) an hour. The distance from the Earth to the Moon is about 239,000 miles (384,633 kM). This seems pretty fast and indeed theory says that nothing can travel faster than the speed of light.
