Both of those seem logical conclusions, yes. Of course, the universe was opaque to electromagnetic radiation for about the first 700,000 years after the big bang, but theory has it the neutrino pulse was released only 1.09 seconds after the bang (at which time the temperature was still 1010K). So you could probably have tested the multiple-traversal theory at that point, given an instrument constructed entirely of neutrinos. ;)
