Dust Bunnies and Dark Matter

As most of us know, dust is an all-surrounding thing. No matter how much we clean our houses, apartments, work areas, automobiles or even our computers, dust continues to mount its daily attack on humans. If left unchecked, dust can collect into a thin layer or even more sinister, it can collect into a loose ball that even a slight breeze can move. This formation is known as the “dust bunny” and it waits in hidden areas until you have guests. Then it comes out to embarrass you. Oh no!
The universe has the same problem of “dust”. Very large clouds (and I do mean very large clouds) of “dust” tend to gather together because of gravity and as the dust gathers, the attraction coalesces into stars and/or planets and/or moons depending on the amount of dust that is around. In fact, our star, the Sun is actually an incredibly large “dust bunny”!
Now what if there was “dust” that was so small that we couldn’t detect it? “Dust” as small as the smallest thing we know of (which scientists call the “Planck length”) or perhaps even smaller. What if this very fine “dust” existed in the universe and was floating about in otherwise empty space? As it floats around, the dust combines and forms its own “dust bunnies”. These unstable formations eventually fall apart and go back to their original form of “dust”. This would account for the particles that scientists say blink in and out of the universe, even ones in a vacuum.
This “dust” would also explain "Dark Matter". The combined amount of dust in the vacuum of otherwise empty space would quickly add up to many times the mass of regular matter that we see everyday. Now this might seem impossible but the vast majority of space is empty of regular matter. If it was filled with dust that was imperceptible, the mass of all that “dust” would quickly add up and have a real effect on the universe. The totality of this mass of dust would create a gravitational effect that could change the movement of planets, stars and even galaxies.
To wrap your head around this concept, take for example the weight of the ant and the weight of an average human being. The weight of one human far exceeds that of any one ant, but if you take the weight of all the ants in the world they actually reach the same weight as all the human beings on the planet!
