Web9 de feb. de 2012 · The theoretical mass–radius relation (MRR) for degenerate stars is widely used throughout stellar astrophysics. It allows the routine determination of white dwarf masses from the basic spectroscopic measurements of effective temperature and surface gravity, which leads directly to the white dwarf mass distribution. WebFrom this, we can conclude that the total mass of the observable universe is about. M = 4 3 π r 3 ρ ∼ 9.1 × 10 53 k g. Sine the universe at large is nonrotating and uncharged, it's natural to compare this to a Schwarzschild black hole. The Schwarzschild radius of such a black hole is. R s = 2 G M c 2 ∼ 44 G p c.
