Thanks for sharing. I wish we had a better grasp on what dark matter and energy actually are. I mean they make up 96 percent of the universe that we know almost nothing about. That's pretty amazing.
"A still more glorious dawn awaits
Not a sunrise, but a galaxy rise
A morning filled with 400 billion suns
The rising of the milky way"
"The sky calls to us
If we do not destroy ourselves
We will one day venture to the stars" -Carl Sagan
