Dark Matter and Dark Energy

Dark Matter and Dark Energy. Somehow a post about this seemed fitting for Halloween. And believe it or not, I have been fascinated by it.

From Wikipedia: Dark matter is a kind of matter hypothesized in astronomy and cosmology to account for gravitational effects that appear to be the result of invisible mass. In physical cosmology and astronomy, dark energy is a hypothetical form of energy which permeates all of space and tends to accelerate the expansion of the universe.[1]

It has been¬†hypothesized to help explain the expanding universe and to account for something we don’t know. Interesting. And it is a reminder that there are so many mysteries out there. So many concepts and theories that have yet to be proven or even discovered. Amazing when you think about it.

And according to NASA “more is unknown than known.”
