A heuristic model is proposed for the origin of the cosmic submillimeter background (SMB) reported by the Nagoya-Berkeley collaboration (Matsumoto et al., 1988). In this model, the SMB is interpreted as a direct signature of an epoch of (initial) galaxy formation at z of about 10-15. The sources of the SMB are proposed to be dust-shrouded starburst protogalaxies, similar to the low-redshift extremely luminous FIR IRAS galaxies. The model may also account for a large part of the diffuse soft X-ray background. 170 refs.
