In one sentence

Anthony Peratt's particle-in-cell simulations from the 1980s showed that interacting Birkeland current filaments evolve into spiral and barred galaxy-like shapes under electromagnetic forces, motivating a plasma-based account of cosmic structure formation.

Eric Lerner's plasma cosmology rejects the Big Bang entirely, claims the CMB is thermalized starlight via intergalactic dust, and has argued (most recently in 2022) that JWST images of early galaxies disprove ΛCDM.

Predictions

Galaxy morphology emerges from plasma current interactions, not gravitational dynamics with [[dark matter]]
Strong magnetic field signatures in galactic and intergalactic filaments
Specific polarization patterns in radio observations of galaxies and filaments

CMB arises from thermalized starlight processed by intergalactic dust
Galaxies at high redshift should not show surface brightness dimming consistent with cosmic expansion
Plasma processes account for galaxy rotation without [[dark matter]]

Where it breaks

Simulations show possible plasma structures but do not demonstrate that gravity is dispensable on cosmic scales
Does not address CMB, primordial nucleosynthesis, or the Hubble diagram
Most cosmologists find the simulations qualitative and unable to reproduce quantitative observations like galaxy rotation curves better than gravitational models with dark matter

The CMB blackbody spectrum is too precise to be reproduced by dust thermalization
Surface brightness analysis of JWST data with proper k-corrections and sample selection remains consistent with ΛCDM
Has not produced a quantitative fit to the combined dataset of CMB, BAO, SNe, and large-scale structure

Key unresolved problem

The numbers problem: the simulations make filaments that look roughly right, the qualitative morphology, but cannot match precise measurements like the ripple pattern in the cosmic microwave background or the amounts of light elements forged in the early universe.

The recycled-starlight problem: no amount of warming starlight on intergalactic dust, dust thermalization, can match the near-perfect even glow of the cosmic microwave background, measured to one part in ten thousand, without leaving telltale spectral distortions.
