Dark Matter

“Oh, I LOVE winter,” younger me used to say. “It’s so much fun, you can cross country ski, and snowshoe and make snowmen and it’s so cozy.”

I suppose it was last winter that did me in. So now, winter has become my time for escape. And my escape in winter is reading about physics and astronomy. As the white stuff piles up and daily living is more of a chore of shoveling snow and hauling wood, to curl up and read about the tiny world of quarks or the vast world of galaxies is delicious.

Right now I am reading Lisa Randall’s new book Dark Matter and the Dinosaurs (selected by Maria Popova of Brain Pickings as one of the top 15 books she has read this year—a list, BTW, guaranteed to make you feel inadequate.)

Randall talks about dark matter, the concept of which I couldn’t quite grasp for a long time, but now I do. We can’t see dark matter because it doesn’t reflect light and we can’t feel it because its force is too weak to have an effect on us at its level in our everyday lives. But we know it exists because in greater densities it exerts a gravitational force. And not only that, but there is much more of it than the matter we can see. So the truth is, we are literally surrounded by dark matter.

Love that.

As I grow older, more experienced, less sanguine, and more settled into convenience, the awareness of the vast mystery of our Universe is a tonic. And that, perhaps, is the real fountain of youth.
