The weaknesses of the Standard Cosmological Model (the Big Bang) are discussed and a model based on a center oriented relativistic expansion (CORE) is introduced. By first reviewing the fundamentals of the Special and General Theories of Relativity the CORE model is shown to be perfectly compatible with Biblical creation. Unlike some earlier models, it rejects the notion of expanded space, and requires no dark energy. Hubble’s Law is discussed and the Hubble Constant derived theoretically is shown to be in agreement with the observed value.
