They’re stuck together forever, destined to spend eternity revolving about each other, like . . . like dancers in a waltz, I suppose.” She scribbled a note in her notebook. “The fascinating thing is, a binary star’s center of gravity isn’t in one star or the other. It’s in the empty space between them.”
