    We might not be able to see dark matter, but that doesn’t mean we can’t understand it.

    Has anyone ever told you, “I’ll believe it when I see it?”

    It’s fine to want tangible evidence of something. But this leaves us on shaky ground when it comes to dark matter; even though it’s all around you, you can’t see it.

    In fact, at this very moment, billions of particles of dark matter are moving through you. You can’t perceive them visually because dark matter doesn’t interact with light. Humans also can’t touch or sense dark matter in other ways because it doesn’t have electromagnetic interactions – at least not that science has been able to discover so far.

    So, while it’s uncertain what type of particles compose dark matter, it’s clear that they’re not the typical atoms or elemental particles that humans are familiar with and which we can see.

    In this way, dark matter is a bit like the microscopic world of bacteria that live all around us. We can’t see bacteria, but they’re essential to our healthy functioning. What’s more astounding is that this invisible dark matter makes up 85 percent of all the matter in the universe!

    How do we know?

    Well, dark matter can be detected through its interactions with gravity.

    Everything in the universe is in constant motion, and the rate at which objects like planets and stars move depends in large part on the gravitational pull of massive objects like the sun.

    In the 1930s, scientist Fritz Zwicky was following the velocity of stars and galaxies when he noticed that their visible mass wasn’t enough to account for the gravitational pull being exerted. This led him to the conclusion that there must be matter that we can’t see – he called it dunkle Materie, or “dark matter.”

    Best quote from Dark Matter and the Dinosaurs

    The Sun circles around the center of the Milky Way at 220 km/sec, taking 240 million years to orbit the center of the galaxy.
