Late-Stage Galactic Jets and the Intergalactic Cosmic Cycle

Traditional astronomical theories have long confined galactic jets within a single galaxy, and mistakenly taken black hole gravity as the core driving force of galactic jets. Based on the latest observation of the 23‑million‑light‑year ultra‑long‑distance galactic jet, this paper puts forward a new theory: gravity exists between celestial bodies such as galaxies and stars, while the massive black holes at galactic centers are pure energy without gravity. Galaxies are giant cosmic vortices, rotating driven by vortex centripetal force. All galaxies go through birth, youth, prime, middle age, and ultimate late stage. When entering the ultimate late stage, the galaxy rotates faster and faster, the core pressure rises sharply, and the jet nozzles become narrower, forming an ultra‑long‑distance jet of tens of millions of light‑years. Such jets can cross galaxies and promote the intergalactic cosmic cycle of matter. The M87 galaxy and the Sagittarius A black hole at the center of the Milky Way will also produce such ultra‑long‑distance jets in their late stage. This paper corrects the misunderstandings of traditional theories and fills the theoretical gap in galaxy evolution.
