Relevant principles. In quantum mechanics, the evolution of the state is governed by the Schrödinger equation.The Schrödinger equation obeys two principles that are relevant to the paradox—quantum determinism, which means that given a present wave function, its future changes are uniquely determined by the evolution operator, and reversibility, which refers to the fact that the evolution ...
A black hole is a region of spacetime where gravity is so strong that nothing, not even light and other electromagnetic waves, is capable of possessing enough energy to escape it. [2] Einstein 's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
1972 — James Bardeen, Brandon Carter, and Stephen Hawking propose four laws of black hole mechanics in analogy with the laws of thermodynamics. 1972 — Jacob Bekenstein suggests that black holes have an entropy proportional to their surface area due to information loss effects. 1974 — Stephen Hawking applies quantum field theory to black ...
In physics, black hole thermodynamics is the area of study that seeks to reconcile the laws of thermodynamics with the existence of black hole event horizons.As the study of the statistical mechanics of black-body radiation led to the development of the theory of quantum mechanics, the effort to understand the statistical mechanics of black holes has had a deep impact upon the understanding of ...
He restated and developed the nebular hypothesis of the origin of the Solar System and was one of the first scientists to suggest an idea similar to that of a black hole, with Stephen Hawking stating that "Laplace essentially predicted the existence of black holes". Laplace is regarded as one of the greatest scientists of all time.
The no-hair theorem (which is a hypothesis) states that all stationary black hole solutions of the Einstein–Maxwell equations of gravitation and electromagnetism in general relativity can be completely characterized by only three independent externally observable classical parameters: mass, electric charge, and angular momentum.

Founded in 1889, Clemson is the second-largest university by enrollment in South Carolina. For the fall 2023 semester, the university enrolled a total of 22,875 undergraduate students and 5,872 graduate students, and the student/faculty ratio was 15:1. Clemson's 1,400-acre (570 ha) campus is in the foothills of the Blue Ridge Mountains.
The following outline is provided as an overview of and topical guide to black holes: Black hole – mathematically defined region of spacetime exhibiting such a strong gravitational pull that no particle or electromagnetic radiation can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform ...
