" The relationship between physics and war is clear: the ruler and the general want to threaten or obliterate targets; destruction requires energy; the physicist is the expert on matter, motion, and energy. It's the physicist who invents the bomb. But to destroy a target, you have to locate it precisely, identify it accurately, and track it as it moves. That's where astrophysics comes in. Neither protagonists nor accomplices, astrophysicists are accessories to war. We don't design the bombs. We don't make the bombs. We don't calculate the damage a bomb will wreak. Instead, we calculate how stars in our galaxy self-destruct through thermonuclear explosions – calculations that may prove helpful to those who do design and make thermonuclear bombs. "
