Dark Matter

Imagine watching a merry-go-round spin really fast. Usually, the kids would fly off, but they stay on because they are holding invisible ropes. Dark matter is like those invisible ropes. We can't see it, smell it, or touch it, but it's the "glue" that keeps galaxies from flying apart.

Most of the universe is hidden from our eyes, but it is still holding us in its arms.

Dark Matter is hypothesized matter that does not interact with the electromagnetic spectrum but exerts gravitational influence. Evidence includes galactic rotation curves and gravitational lensing. It constitutes roughly 27% of the universe's mass-energy content. It teaches us that Reality is not synonymous with Visibility — the "We" includes the unseen.

SOUND: The wind whistling through trees. You can't see the air, but you hear what it does to the leaves.

SMELL: Fresh air. You can't see it, but you know it's filling your lungs.

TASTE: The "fizz" in sparkling water. You can't see the bubbles easily, but you feel their effect on your tongue.

TOUCH: Moving your hand through water. You feel the resistance even if the water is perfectly clear.

SIGHT: Look at a spiderweb in the dark. You only see it when a tiny bit of dew or light catches it, but it was there the whole time.

BODY: Walk through a dark room. You "feel" the presence of furniture before you bump into it.
