Since the CMB results of the past decade, would it be fair to say that the concensus among cosmologists is that cosmic strings are no longer considered as a (major) source for density perturbations?
Is so, what are the leading theories to explain how the universe developed inhomogeniety from a nearly uniform early universe?
What are the active areas of research for within structure formation today, besides relying upon relativistic pertubration methods? Is there a recent review for a status of the field today?
