DESCRIPTION:I shall show that magnetic fields generated during inflation\,
  if they are sufficient to provide the seeds for the observed large scale 
 fields in galaxies\, clusters and voids\, generically lead to large metric
  fluctuations during the subsequent radiation era. The ratio of the Weyl t
 ensor generated from magnetic fields during inflation to the Ricci\ntensor
  grows in the radiation dominated era to become larger than unity. This is
  in flagrant contradiction with the homogeneity and isotropy of the observ
 ed Universe\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=183696
