You don’t need to pity them. Really, let me tell you: don’t. The reality of the universe is not something to envy.” “Why?” Yifan lifted a hand and pointed at the stars of the galaxy.

The universal laws of physics are the most terrifying weapons, and also the most effective defenses. Whether it’s by the Milky Way or the Andromeda Galaxy, at the scale of the local galactic group or the Virgo Supercluster, those warring civil
