Light bulbs should be called darkness eradicators.
Pretty simple, it's not that they propagate light, they actually suck in darkness.
Pretty simple, turn on your desk lamp or even your room light, place your hand over the table or something. What happens? There is darkness that we call the shadow under your hand. Why is that so? It's because you blocked the path of the so called light bulb to suck in the darkness.
How can I support this?
If you noticed, light is not infinite. For example, take the light from the lamp post a couple of blocks away or maybe the light from your neighbor, what do you notice? Sure you can see the light but it doesn't illuminate your spot, because it is finite. Just like how stars in the universe behave, they don't illuminate the darkness that is the universe.
Back to the tangible example, our light bulb. Ever wonder why it suddenly stops working? When they refuse to light up and you have to replace it? It's because they're full of darkness already and they can't take in anymore. Maybe another clear example of this would be fire, notice that the thing it eats turn black? Because the plasma of the fire materializes the darkness around it and you have ashes left.
So it's not that darkness is the absence of light. It's the other way around but it's just that we never really had any concrete ways on studying darkness.
Take photons for example, they "kill" the darkness around them by propagating in waves/particles whatever your quantum physics tell you. But the thing is as they propagate as waves, they suck in the darkness by passing it back to be contained inside the bulb. Imagine a dragon boat, the rowers paddle to go forward, and as they move forward, some of the water gets pushed back which is the nature of the motion in rowing.
So from the "science" of light, let's go to philosophy.
So what does this theory say about human beings since we passively create shadows? Remember the Chinese Philosopher Xunzi/Hsun Tsu, no not the one who wrote the Art of War, that guy is Sun Tsu. Xunzi said that it's the nature of man to do evil, to propagate darkness, but we also recognize our capacity to do good, so we eradicate darkness.
Actually I had much more ideas to put on this theory but they left me. I was thinking of this in all seriousness and it never occurred to me that I could be trolling until I re-read this post.
Going back to the light bulb, they burn out right? That could be extended to the universe, ever wondered how white dwarfs and black holes are formed?
White dwarfs are basically big ass stars that quit halfway. So they were sitting around the universe, being the all powerful darkness eradicator in their region with a couple or so friends making up a galaxy of some sort. They were given the task to illuminate their region for a couple hundred of years or so, but of course who wouldn't get bored of that? So halfway through, they got fed up and experimented with the darkness inside them. But in doing so, boom, darkness got out and in a last ditch effort, and realizing the gravity of their responsibility, the dying star mustered all of its remaining darkness eradicating powers and formed into a white dwarf.
Black holes are basically those guys who went all the way and got corrupted. Actually they're pretty worse than the light bulbs who got burned out. Black holes are like fallen angels a.k.a. devils. They were once also powerful stellar beings kicking darkness ass but after a lifetime of being a hero they ran out of energy and eventually die, only for their dying bodies to be made home to darkness. That's also why black holes eat up light. Much like devils, devils don't just go chill in Hell, they go drag angels and innocent human beings to join them there. Black holes don't go chill in the cold space that they're in, they go drag up light to join their party. Well of course it depends if the light wants to join or not. Because if the light is pretty much a baller and fights darkness to death, he will get eaten by the black hole, the same goes for pussy traitors. But, there's another case, if the light realizes that it's pretty much stupid to fight darkness since he's pretty outnumbered, he'll bend the time space continuum in order to get out of there, but in the process, time travels to the past or future.
