- Christian universalism is a school of Christian theology focused around the doctrine of universal reconciliation – the view that all human beings will ultimately be saved and restored to a right relationship with God. “Christian universalism” and “the belief or hope in the universal reconciliation through Christ” can be understood as synonyms. Opponents of this school, who hold that eternal damnation is the ultimate fate of some or most people, are sometimes called “infernalists.”
- General relativity (Wikipedia)
General relativity, also known as the general theory of relativity and Einstein’s theory of gravity, is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics. General relativity generalizes special relativity and refines Newton’s law of universal gravitation, providing a unified description of gravity as a geometric property of space and time or four-dimensional spacetime. In particular, the curvature of spacetime is directly related to the energy and momentum of whatever matter and radiation are present. The relation is specified by the Einstein field equations, a system of second order partial differential equations.
