Abstract
Astrophysics has its ironies. Here’s one: Studies of the brightest galaxies in the universe led to the discovery that 99 percent of all matter is "dark matter".1 But matter is only part of the universe (about a fourth). The rest is energy. Adding irony to irony, research focusing on the brightest stars in the universe shows that "dark energy" is far more abundant than dark matter, making up most of the rest of the universe. Despite its often negative connotation, this "darkness" is not a bad thing.
