The Standard Model
The conventional cosmology story comes courtesy of the Lambda cold dark matter (ΛCDM) model, which emerged in the late 1990s. Further exploration of ΛCDM, beyond its 13.82 BYA Big Bang and mythical cosmic inflation, reveals further inanities which discredit it.
The canard of cosmic inflation arose from thinking that the universe began with the 1st discernible light. Instead, the early universe was nearly pitch black, filled with a miasma of light elements: hydrogen, helium, and lithium, until stars formed and baked heavier elements, creating a faintly luminous byproduct.
Not until stars formed were there loci of light. Dispel the notion of the universe starting like the torching of a firecracker and there is no need for the physics-defying folly of cosmic inflation.
