Weak lensing exhibits that rotation curves of isolated galaxies remain flat up to Mpc scale (Mistele T. et al. Astrophys. J. Lett.9692024L3). Recently we proposed that dark matter is a combination of electrostatic and vacuum energy in standard physics. In this theory, isolated galaxies may be embedded in “charged cocoons”, spheres with 
charge density. The related circular rotation curves decay at the Mpc scale. The analytic solution is extended to the early Universe. A peak in the cosmic microwave background spectrum is expected at the arcsec scale. The induced nanometer size of the cocoons at the Big Bang makes the initial state inhomogeneous.
