Unformatted text preview: 1/m^2.5 gives answer in solar lifetimes If you know mass of a star on main sequence, you can get its luminosity. Lifetime of universe Geometry of universe (the confusing graph. Ω = ΩA + Ωm = 1) which tells us universe is flat. Lifetime of star clusters (age is same as the star just now dying off main sequence) F = L / 4pid^2 (this is how we get distance) this could be related to D in hubble’s constant which could then go into age of the universe which could conflict with the age of a star cluster See how formulas relate...
