There may be such intelligences and such starships, but pulsars are not their signature. Instead, they are the doleful reminders that nothing lasts forever, that stars also die. We continue to plummet, falling thousands of light years towards the plane of the galaxy. This is the Milky Way -- our galaxy seen edge-on, billions of nuclear furnaces converting matter into starlight. Some stars are flimsy as a soap bubble, others are 100 trillion times denser than lead, the hottest stars are destined to die young, but red giants are mostly elderly.
