| 内容記述 | The possibility of the microwave background being produced by stars after the big bang is considered. The critical problem for this hypothesis is the source of the long-wavelength opacity for observed wavelengths greater than 10 cm. It is shown that free-free opacity cannot thermalize the background. Spherical dust grains also fail, but needle-shaped conducting grains can provide sufficient opacity to produce the observed spectrum with a metal abundance Z approximately equal to 10 to the -7th. |
