Thanks, however that's not very much mass unless it excludes black and white holes of matter/antimatter or them Plancks as minimal wavelength photons, whereas by some accounts, such Plancks as quantum particles are supposedly massive enough to be quantum black holes, as considerably more dense than any electron or positron. So, how far off is the 1.6e60 kg and 1e84 atom mark for that estimate or swag representing the mass of our universe? ~ BG |
