The most commonly used noun in the English language is time. Yet time is nothing more than an idea. It is an intangible concept invoked to make sense of the world such that, ‘everything doesn't happen at once,' as Einstein said. The actual most common thing in the universe is dark matter. Dark matter purports to be more than an idea. It has some kind of elusive tangible existence, yet it has never been held in anyone's hands.
The nearly invisible components of nature such as cells or atoms can only be seen with the aid of tools. If you see a cell with a microscope there exists a physical and philosophical stratification between your perception, your eye, the optics of the microscope, and the observed cell. If you see an atom on a computer monitor rendered from data from an atomic microscope then the layers of complex stratification between you and the atom are monumental. What can we truly know about the nature of things which can only be observed through tools? I would argue quite a lot. Dark matter will always remain isolated from basic human perception, but we can know it through tools or imagination.
Imagine a sea of particles gliding through you unnoticed; this is dark matter. Imagine anything, and dark matter doesn't stop for it. Dark matter doesn't interact strongly with earth, fire, wind or water. There are many particles that have elusive existences similar to dark matter like photons or neutrinos. Unfamiliarity with these known particles doesn't hinder your ability to imagine dark matter: even these particles were not discovered without stratification between human perception and the thing itself. Imagine bits of dark matter passing through you brain at this moment, every moment, because it probably is. And if it is, but it never interacts with you in any way, does it matter?
