Scientific paper

The possibility that pregalactic black hole accretion could have heated the universe sufficiently to produce the hard X-ray background through bremsstrahlung emission is considered here. This would only be possible if the holes were implausibly large. It is suggested that these holes could be the precursors of the holes which may presently be powering Seyfert galaxies or quasars.
