From: Tony Li <Tli @ Usc-Eclb> Hi, Vacuum is measured in torr. 1 torr = 1.316E-3 atmospheres. Density is always in units of mass/volume. Vacuum does not have mass, and hence, cannot have a density. Further, the sun radiates a solar 'wind' which is composed of large numbers of particles. A moments thought will indicate the gradient established by the density of these particles as they are ejected. Hence, not only was the earlier statement poorly worded, but it was also blatantly incorrect. Cheers, Tony ;-) p.s. Nuf said.
