It blocks various light rays; I think that’s why it’s called dark. The disturbing idea is that “space” is not really empty.
I honestly don’t understand the entire concept of dark matter. They say it makes up a huge part of our universe and it’s everywhere holding everything together.
If that’s true then why isn’t the stuff all over my lawn?

I didn’t think it was dark but cosmologists have to add it to their equations to make things balance out. Boo! Happy Halloween!
...”The disturbing idea is that “space” is not really empty.”
Like multidimensional invisible stuff that could go thump in the night? No PPDs apply.
