idleCycle rated 4 months ago- Note that the milky way - our galaxy has about a 3.7 million solar mass black hole. It has globular clusters in the halo that appear to be about 10 billion years old and should have had this active galactic nuclei quasar period. Yet, we see the sun as about 5 billion years old and we see plenty of galactic gas and dust and we obviously see ongoing star formation, from some in the first phases to the existence of very high massive stars that have lifetimes far shorter than the time since the dinosaurs went extinct. All of this local evidence refutes the basic notions of the article unless one adds the notion that the stars are reseeding the galaxy and forcing the return of star formation. You'll note the sun is not a first generation star nor probably even a second or third generation one. The material the sun formed from was ejected by earlier stars.
