Dark Matter Holds Everything Together

Interesting news story out today about how astrophysicists have discovered a galaxy relatively close to our own that is comprised almost entirely of dark matter. Our Milky Way has about 100 times more stars than the galaxy in question, yet they’re both about the same size. Fascinating.

They (the proverbial they–though, in this case it refers to more of those astrophysicists) calculate that the universe is about 85% dark matter, with the balance being made up of visible matter: us, stars, planets, etc. Dark matter earns its name by not absorbing or reflecting light. Its invisible. You can only detect it by observing its gravitational effects on other things.

Which means if you see someone staggering oddly down the street, they’re either inebriated or under the influence of dark matter.

And dark matter, even more interestingly enough, holds the universe together. Some might say the word holds the universe together. The first spoken word. Rather, the word that came before the first spoken word. Dark matter or first words. They’re bother difficult to see, yet we see their effects everywhere.

I wanted to be an astrophysicist when I was a kid. I never wanted to be a fireman or a policeman or a mutual fund manager. It was always an astrophysicist for the longest time. Funny how we end up in other places. I’ll chalk it down to the unseen influences of dark matter. The gravitational pull of that which cannot be seen.
