Same as the speed of light. Darkness is only the absence of light, so when light leaves a specific "space" (at the speed of light) then the time it takes to be dark there will be equal to the time it takes the light to leave.

No, asteroids do not travel faster than light. Light travels at a speed of about 186,282 miles per second (299,792 kilometers per second) in a vacuum, which is the maximum speed at which anything can travel in our universe. Asteroids typically travel much slower than the speed of light.
No, it is not possible to travel at the speed of light in water. Light travels at a slower speed in water compared to its speed in a vacuum, which is about 299,792 kilometers per second. The speed of light in water is approximately 225,000 kilometers per second.
Light travels at a speed of 186,000 miles per second, in a vacuum.
Light travels approximately 0.3 millimeters in one trillionth of a second.

No
Light waves always travel at the speed of light ... whatever it may be inside the material they're traveling through. They only travel at 300,000 kilometers (186,282 miles) per second in vacuum.
Light second
The speed of light is 186,282 miles per second.
Light waves travel at their fastest in a vacuum, where they travel at the speed of light, which is approximately 299,792 kilometers per second.
299,792.458
Yes, it does.
299,792,458 meters/second
less than a second if a mirror a second
In a vacuum, light will travel 299,792,458 meters in one second.
Light could travel seven and a half times around the world in one second.
