Recent studies challenge the long-held belief that the Milky Way is a standard model for understanding galaxy formation, revealing unique differences in its structure and evolution compared to its galactic peers.
The SAGA Survey has begun to uncover these discrepancies by studying over 100 Milky Way-like galaxies, shedding light on the complex role of dark matter and the diverse evolutionary paths of galaxies.
They’re talking about galaxy formation. There’s no obvious implications for the formation of life.
That said, we are already alone. And there’s a good chance we always will be whether other sapient life forms are out there or not. That’s not sad, we’re just lucky we’re here at all.
