No, Albert Einstein did not reject the Big Bang theory because of its theological implications. In fact, Einstein played a significant role in the development of the Big Bang theory.
The Big Bang theory suggests that the universe originated from a singular, extremely hot and dense state around 13.8 billion years ago. It was first proposed by the Belgian priest and physicist Georges Lemaître in the 1920s, based on Einstein's theory of general relativity. Lemaître's theory gained traction in the scientific community, and Einstein himself initially resisted it, preferring a static universe model.
Einstein's initial skepticism of the Big Bang theory was not due to theological concerns, but rather because he held a preconceived notion of a static and unchanging universe. He introduced a cosmological constant into his equations to maintain a static universe, a decision he later regarded as his "greatest blunder" when evidence for the expansion of the universe became apparent.
Einstein's rejection of the early versions of the Big Bang theory was based on scientific considerations and his preference for a static universe, not theological implications. It is worth noting that Einstein's personal beliefs regarding religion and the nature of the universe were complex, and he often expressed a sense of awe and wonder at the mysteries of the cosmos. However, there is no evidence to suggest that theological concerns played a significant role in his scientific thinking or his acceptance of the Big Bang theory.
