Is the basic argument that is made in the book "The Big Bang Never Happened", by Eric Lerner around 1995 basically saying that the doppler effect in the red shift has been misinterpreted to mean that the universe is expanding when in fact the it's due to dust slowing light down?

You're on the right track, but there's more to it than *just* dust slowing light. Here's a breakdown of Lerner's argument in "The Big Bang Never Happened":
* **Redshift Interpretation:** Lerner challenges the standard interpretation of cosmological redshift as solely due to the expansion of the universe (as predicted by the Big Bang theory). He argues that the observed redshift is not necessarily a measure of recessional velocity.
* **Plasma Cosmology:** Lerner promotes an alternative model called plasma cosmology. This model posits that the universe is filled with vast networks of plasma filaments and that electromagnetic forces play a dominant role in shaping the cosmos, even at very large scales.
* **Challenging the Evidence for the Big Bang:**
* **Redshift as Intrinsic Property:** Lerner argues that at least part of the observed redshift is not due to the expansion of the universe, but rather is intrinsic to the light itself, being affected by its passage through plasma and dense filaments. He doesn't necessarily say it's only dust (although dust does play a role in absorbing and scattering light), but more generally that interactions with matter (especially plasmas) change the properties of light, including its wavelength.
* **Cosmic Microwave Background (CMB):** Lerner argues that the CMB is not primordial radiation from the early universe, but rather is generated by absorption and re-emission of light by hot, dense plasma filaments.
* **Abundance of Light Elements:** The Big Bang model predicts specific ratios of light elements (hydrogen, helium, lithium). Lerner argues that these abundances can be explained by other processes, particularly within stars.
* **Galactic Evolution:** Lerner claims that the observed structure and evolution of galaxies is inconsistent with the predictions of the Big Bang model, particularly the need for dark matter to explain galaxy rotation curves.
* **Steady State Universe:** Lerner's plasma cosmology aligns more closely with a steady-state universe concept. In this view, the universe is infinitely old and has always existed in more or less its current state, with matter constantly being created and recycled.
**In summary:**
Lerner's argument is not *solely* about dust slowing light. It's a much broader challenge to the Big Bang, with the interpretation of redshift (and other observational data) being a key point of contention. He posits that alternative processes, especially interactions with plasma, are responsible for the observed redshift and that a plasma-dominated universe is a more accurate representation of reality. Lerner's model is not widely accepted by the scientific community. It does not have as strong of predictive power, and fails to account for many of the observations that are consistent with the standard model. [Rick says-- of course AI has to use a disclaimer so that no conclusion can be reached but notice how weak the disclaimer is compared to the stunning reasoning of Lerner.]
