Stephen Hawking and C.J. Hunter Paper: 'The Gravitational Hamiltonian in the Presence of Non-Orthogonal Boundaries'

In 1996, Stephen Hawking and C.J. Hunter made significant contributions to the field of theoretical physics with their paper titled 'The Gravitational Hamiltonian in the Presence of Non-Orthogonal Boundaries', published in the journal Classical and Quantum Gravity. This work delves into the complexities of formulating the gravitational Hamiltonian in spacetimes characterized by non-orthogonal boundaries. The authors explore how these non-standard boundary conditions affect the dynamics of gravitational systems, providing a deeper understanding of the implications for general relativity. Their findings are crucial for researchers working on the foundations of quantum gravity and the interplay between geometry and physical laws. By addressing the challenges posed by non-orthogonal boundaries, Hawking and Hunter's research opens new avenues for exploring gravitational theories and their applications in cosmology and black hole physics. This paper is a vital reference for physicists interested in the mathematical underpinnings of gravitational theories and the role of boundary conditions in the formulation of physical laws in curved spacetime. #mooflife #mof #MomentOfLife #GravitationalHamiltonian #Non-orthogonalBoundaries #StephenHawking #ClassicalAndQuantumGravity #GeneralRelativity
