That seems fanciful to me at best since there is no support for it. However, the rotation curves of numerous galaxies, including our own, give abundant support for its existence. It could be cosmic strings, massive neutrinos, non-luminous Byronic matter, etc. This does not mean that I discount the many worlds hypothesis of quantum mechanics or it many cosmological ramifications, just that anything such as you raise is little more than speculation.
