Causality and Prediction in Modern Cosmology

The modern cosmology is based on the observational evidences, but several philosophical principles and metaphysical prejudices play an undeniable role in it. This paper surveys some important attitudes such as causality, prediction, determinism etc. in the general relativity and cosmology. The general relativity is a deterministic theory (apart from the singularities) and is applied in prediction of the universe large-scale evolution. However, the acceleration of the universe, noticed at the end of last century, leads to a revolutionary view in the prediction in the cosmology. Subsequently, because of the unknown nature of the acceleration driver, there is an unavoidable uncertainty in this prediction. It is asserted in this article that the cosmologists’ unscientific assumptions, veiled in their scientific claims, affect strictly on their outcomes.
