Missing mass
Can anyone give me correct figures on missing mass? I think we actually
observe less than 3% critical mass, plus a bit in CDM haloes. That leaves about 27% cold dark matter calculated mainly from the magnitude-redshift relation, using supernovae as standard candles. Is this right? Do we calculate a figure from the microwave background based on the universe having 1/1000 its current size at decoupling. Do we know density at decoupling? -- Best regards Charles Francis
