Can a Black Hole Collapse to a Space-time Singularity?
A critique of the singularity theorems of Penrose, Hawking, and Geroch is given. It is pointed out that a gravitationally collapsing black hole acts as an ultrahigh energy particle accelerator that can accelerate particles to energies inconceivable in any terrestrial particle accelerator, and that when the energy E of the particles comprising matter in a black hole is ∼ 10GeV or more, or equiva...
متن کاملSpace-Time Non-Commutativity near Horizon of a Black Hole
We consider dynamics of a quantum scalar field, minimally coupled to classical gravity, in the near-horizon region of a Schwarzschild black-hole. It is described by a static Klein-Gordon operator which in the near-horizon region reduces to a scale invariant Hamiltonian of the system. This Hamiltonian is not essentially self-adjoint, but it admits a one-parameter family of self-adjoint extension...
متن کاملZorah Lähner Time-Discrete Geodesics in the Space of Shells Time-Discrete Geodesics in the Space of Shells
Based on a paper from Heeren et al. this report presents a method of finding a natural deformation between two shapes with a given correspondence. It is based on minimizing an energy function derived from results of elasticity theory. Different than other algorithms this energy has only parameters with concrete physical meanings. Furthermore proper discretization methods are presented. The resu...
متن کاملTime-Discrete Geodesics in the Space of Shells
Building on concepts from continuum mechanics, we offer a computational model for geodesics in the space of thin shells, with a metric that reflects viscous dissipation required to physically deform a thin shell. Different from previous work, we incorporate bending contributions into our deformation energy on top of membrane distortion terms in order to obtain a physically sound notion of dista...
متن کاملGeodesics in Shape Space via Variational Time Discretization
A variational approach to defining geodesics in the space of implicitly described shapes is introduced in this paper. The proposed framework is based on the time discretization of a geodesic path as a sequence of pairwise matching problems, which is strictly invariant with respect to rigid body motions and ensures a 1-1 property of the induced flow in shape space. For decreasing time step size,...
