Dark Matter

“One of the things I love about science is that we don’t have to pretend we have all the answers.” -Neil deGrasse Tyson

I finished Cosmos last night. What an absolutely incredible show. The finale got into dark matter and dark energy, which is a subject I’ve been struggling to understand for a long time, so it was reassuring to be reminded that not only do I not understand it but that nobody really does. Yet, we know it is real, and therefore that approximately 70% of the universe is matter and energy that we can’t see and can barely even comprehend. That shit is flabbergasting.

There is a great analogy about sea foam: Up until Fritz Zwicky discovered dark matter we thought we understood the universe, but we were like people standing on the beach at night who thought that sea foam crashing on the shore was the whole ocean. Dark matter and dark energy are the deep, unexplored, just discovered ocean. There is so much we don’t know.
