Black hole singularity is a surface not a point
Andrew J. S. Hamilton, Tyler McMaken
It is widely repeated in the popular literature and elsewhere that the singularity at the center of a black hole is a point. It is not true. Two observers who free-fall into a sphe…
Hawking radiation inside a rotating black hole
Tyler McMaken, Andrew J. S. Hamilton
In semiclassical gravity, the vacuum expectation value of the particle number operator for a quantum field gives rise to the perception of thermal radiati…
Unification of the four forces in the Spin(11,1) geometric algebra
Andrew J. S. Hamilton, Tyler McMaken
SO(10), or equivalently its covering group Spin(10), is a well-known promising grand unified group that contains the standard-model group. The spinors of the group Spin() of rot…
Hawking radiation inside a charged black hole
Tyler McMaken, Andrew J. S. Hamilton
Here we analyze the Hawking radiation detected by an inertial observer in an arbitrary position in a Reissner-Nordström spacetime, with special emphasis on the asymptotic behavior…
The Supergeometric Algebra
Andrew J. S. Hamilton
Spinors are central to physics: all matter (fermions) is made of spinors, and all forces arise from symmetries of spinors. It is common to consider the geometric (Clifford) algebra…
Wave equations in conformally separable, accreting, rotating black holes
Andrew J. S. Hamilton, Tyler McMaken
The Teukolsky wave equations governing fields of spin 0, , 1, , and 2 are generalized to the case of conformally separable solutions for accreting, rota…
