Among the many complex and diverse cosmic star bodies, pulsars count as a relatively special type.
Strictly speaking, a pulsar is a rapidly rotating neutron star; its density is second only to a black hole, and because of its high-speed rotation, it emits electric pulses outward like electron beams, which, in the black ocean of the cosmos, are like the light from a lighthouse.
Exactly because of these Traits, in interstellar navigation it has become a kind of "navigation lighthouse" existence. Some seasoned veterans, like Interstellar Pirates, love to tweak the "lights" and send out encrypted messages.
Blowing up the "lighthouse"—in other words, snuffing out a neutron star—is standard practice in interstellar war.
It's also one of the few star bodies not protected under the Interstellar War Convention issued by the Civilization Council.
And the reason Gao Gong is paying attention to this, aside from using it to confirm the route, is that—using a neutron star, you can pull aggro.
