Compare ΛCDM, inflation, MOND and approaches to quantum gravity.
Cosmological models, scenarios and theoretical approaches operate at different scales. They are not always alternatives: inflation can complement ΛCDM. Status refers to the stated scope, not ultimate truth.
A / COMPARE
ΛCDM
Supported by observations; tensions remain
A decorative transition diagram. These curves are not model predictions or observational data.
Scope
The late universe and its connection to early perturbations
Parameters
H₀, Ωm, Ωb, ΩΛ, As, ns, τ; the number of independent parameters depends on the parameterization.
Predictions
A consistent description of the CMB, large-scale structure and cosmological distances.
Limitations
The nature of dark matter and Λ is unknown; tensions exist between datasets.
