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.
But all of these things are nothing compared to the speed of light, which is the fastest that something can travel through the Universe. The speed of light is sometimes referred to as the âcosmic speed limitâ. Light travels in a vacuum at 186,282.4 miles per second or 299,792,458 meters/second. For simplicity, it is often said that these numbers are 186,000 miles per second, and 3.00 x 10^8 meters per second. How fast is this in normal terms?
