- Primordial isocurvature baryon model
A primordial isocurvature baryon model, or PIB model, is a theoretical
model describing the development of the earlyuniverse . It may be contrasted with the a cold dark matter model, or CDM model. The PIB model was proposed in 1987 byJim Peebles as an alternative to the CMB model which does not necessitate the existence of exoticdark matter . [ Hu (1994-06-28) ] PIB models, which ascribe all cosmic density perturbations to isocurvature modes, predict results that are inconsistent with the observational data.
