What Is the Speed of Darkness | Darkness Vs Lights

What is the Darkness?

Darkness is the absence of light, and it is a state that occupies most of the universe. There is very little light in the space between the galaxies, which looks like small spots.

That's why it looks black in the pictures taken with binoculars. Light propagates in every direction and its speed is 0.3 million kilometers per second.

But the farther it goes from its source, the more it slows down. Due to the burning and extinguishing of the source of light, gaps of darkness are formed, the speed of these gaps is the same as the speed of light. Imagine that the sun suddenly stops shining, then in this situation the darkness will reach us with a delay of about 8 minutes because  sunlight also take 8 minutes to reach to the earth.

But the speed of darkness is different, the earth rotates on its axis and complete its one cycle in every 24 hours.

And when the earth moves away from the sunlight, there is darkness, that is, it becomes night in that part of the earth. Around(The equator divides the globe into two hemispheres.)the equator, this darkness travels at a speed of 1600 kilometers per hour. Because the galaxies are rapidly getting scattered, the light emitted from them will start to appear faint and according to the theory, in the distant future the sky will be completely dark.
