  It is postulated that the energy density of the (quantum) vacuum acts firstly
as dark energy and secondly as a part of dark matter. Assisted by electric
fields arising from a small charge mismatch in the cosmic plasma, it can
condense on mass concentrations. No longer participating in the cosmic
expansion, this constitutes ``electro-aether-energy'' (EAE),
``electro-zero-point-energy'' or ``electro-vacuum-energy'', which solves the
dark matter riddle without new physics. A radial electric field of 1 kV/m is
predicted in the Galaxy. For proper electric fields, EAE can cover the results
deduced with MOND. An instability allows a speedy filling of dark matter cores.
Hydrostatic equilibrium in galaxy clusters is obeyed. Flowing in of EAE
explains why black holes become supermassive, do not have mass gaps and
overcome the final parsec problem. Rupture of charged clouds reduces, e. g.,
the primordial baryon cloud to the cosmic web. The large coherence scale of the
electric field acts as a scaffold for gentle galaxy formation and their vast
polar structures. In galaxy merging and bars, there occurs no dynamical
friction. At cosmological scales, EAE acts as pressureless dark matter. Its
amount increases in time, which likely solves the Hubble tension by its late
time physics. A big crunch can occur. Of the large cosmological constant
injected at the Big Bang, a small part kept that form, without fine-tuning.
