The Big Bang never happened: CMB is thermalized starlight and JWST disproves expansion.

In one sentence

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.

Why this was rejected

  • Lerner's own 1995 CMB alternative explicitly acknowledges that no plasma-based model reproduces the observed CMB isotropy at the 1-in-100000 level.
  • Multiple astrophysicists analyzed the 2022 JWST claims and found his analysis used simplified assumptions, mixed selection-biased samples, and lacked proper k-corrections. With proper modeling, JWST counts remain compatible with ΛCDM with some tensions, not wholesale falsification.
  • His JWST claims have not been published in major peer-reviewed cosmology journals; they remain in preprint, talk, and popular-article form.

The claim

Eric Lerner, the most visible modern advocate of plasma cosmology, presented an explicit alternative to the Big Bang in his 1991 book 'The Big Bang Never Happened.' His framework emphasizes laboratory plasma experiments and electric currents as templates for cosmic structures, claims the CMB is thermalized starlight rather than primordial relic radiation, and rejects cosmic expansion.

In 2022, soon after early JWST deep-field images were released, Lerner argued they disprove the Big Bang because high-redshift galaxies appear too bright, too large, and too well-formed for ΛCDM's galaxy formation timeline. His JWST analysis has not been published in major peer-reviewed cosmology journals and is rejected by mainstream cosmologists for methodological issues.

The family stance

The universe is structured by plasma physics and electromagnetic forces operating on cosmic scales. There is no singular beginning; cosmic structure arises from current sheets and plasma instabilities rather than gravitational collapse from a hot Big Bang.

Predictions

  • 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

Evidence

  • Lerner has identified real tensions in early galaxy formation efficiency that ΛCDM still grapples with
  • The framework's emphasis on plasma is consistent with the empirical dominance of plasma in cosmic baryonic matter

Counterpoints

  • 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
