Darkness isn't a thing, it's the absence of something.
* Light travels at a specific speed: The speed of light in a vacuum is approximately 299,792,458 meters per second. This is the fastest speed anything can travel in our universe.
* Darkness is the absence of light: When no light reaches our eyes, we perceive darkness. It's not something that travels or has a speed.
So, darkness doesn't have a speed.
Think of it like this: if you have a room with a light on, and you turn the light off, the darkness didn't "move" into the room. It's simply the absence of light.
The illusion of darkness "moving"
Sometimes it might *feel* like darkness is moving. For example, if you're driving at night and pass under a bridge, it might feel like the darkness "swallows" you up. But what's really happening is that the light from your headlights is being blocked by the bridge, and you are entering an area where there is no light.
