@konstructivizm If we're in a low density void, then maybe because there is a greater density of stars and planets outside of our positioning, there is a greater chance of life outside of the milky way.

Black Hole@konstructivizm·
Astronomers have found growing evidence that the Milky Way is located inside a vast cosmic void—a region of space roughly 2 billion light-years across that contains significantly less matter than the cosmic average. This underdensity, sometimes called the KBC Void or Local Hole, features a matter density about 20–30% lower than typical regions of the universe.On the largest scales, the universe is not uniform: matter clumps into enormous filaments, walls, and clusters, separated by immense voids where galaxies and gas are sparse. Gravity in these voids is slightly weaker due to the reduced mass.This local underdensity may resolve the long-standing Hubble tension—the discrepancy between two primary measurements of the universe's expansion rate (the Hubble constant). Measurements of the nearby universe, using supernovae and Cepheid variables, suggest a higher value (73 km/s/Mpc) than those derived from the early universe via the cosmic microwave background and baryon acoustic oscillations (67 km/s/Mpc).If we live in a large void, the reduced gravitational pull from surrounding matter allows nearby galaxies to recede faster than expected in an average region. This local "boost" in apparent expansion mimics a higher Hubble constant without requiring revisions to fundamental physics or cosmology.Recent studies, including analyses of baryon acoustic oscillations and galaxy distributions, show that void models fit observational data substantially better than assuming uniform density. If confirmed, this would mean our cosmic neighborhood is atypically empty, biasing local measurements and forcing astronomers to adjust interpretations of expansion history and large-scale structure.Living near the center of such a giant void would mark a profound shift in our understanding of the universe's homogeneity—and a reminder that our vantage point may not be as representative as once thought.

@Xolaffy_ America hates women in general. Ask Hillary and Elizabeth Warren. We’re screwed.
