Why do you want to talk about darkness?
The whole Universe is enveloped by darkness - Dark Energy and Dark Matter. Scientists today say that what you see today as light is only a spot; it is like a bubble in a water bottle. Light is like a bubble in a water bottle. But the water is the real thing. The bubble is simply what appears. That is not the real thing.
So the Sun, of course we know is the source of energy. But the scientists say that, what keeps the Sun tight and round in shape is the Dark Energy around it. So the Dark Matter and Dark Energy is a million times more powerful than the Sun. Like air bubble inside a water bottle is just air trapped by the pressure of all the water molecules. Now water is heavier and so much more powerful than the air. Similarly the whole Universe is filled with energy which you cannot see and which you don’t know. And you think there is nothing in it.
The black holes, what the scientists call it, can just swallow the Sun. Our Earth, the Sun and our solar system is simply escaping and moving in between huge black holes.
So many black holes are there in the universe, and if the Sun gets even a little close to it then it just sucks the whole Sun, and nobody knows where it disappears. So the whole Universe is filled with that energy which is not seen, that is why it is called Dark Energy or Dark Matter.
