That the anisotropies in the CMB are small puts sufficient limits on structure formation in the earlier universe that our observations (even at COBE scale, let alone from recent observatories) preclude your idea. AMS 02 results to date essentially…</p><p><a href="https://hackerpaper.kaipfister.de/p/1204.4186/">Paper and discussion history</a>. A mention is not an endorsement.</p>hep-ph
