Anisotropic evolution of D-dimensional FRW spacetime
Chad Middleton, Bret A. Brouse, Scott D. Jackson
We examine the time evolution of the D=d+4 dimensional Einstein field equations subjected to a flat Robertson-Walker metric where the 3D and higher-dimensional scale factors are al…
Elliptical-like orbits on a warped spandex fabric: A theoretical/experimental undergraduate research project
Chad A. Middleton, Dannyl Weller
We present a theoretical and experimental analysis of the elliptical-like orbits of a marble rolling on a warped spandex fabric. We arrive at an expression describing the angular s…
The 2D surfaces that generate Newtonian and general relativistic orbits with small eccentricities
Chad A. Middleton
Embedding diagrams prove to be quite useful when learning general relativity as they offer a way of visualizing spacetime curvature through warped two dimensional (2D) surfaces. In…
Circular orbits on a warped spandex fabric
Chad A. Middleton, Michael Langston
We present a theoretical and experimental analysis of circular-like orbits made by a marble rolling on a warped spandex fabric. We show that the mass of the fabric interior to the…
Anisotropic evolution of 5D Friedmann-Robertson-Walker spacetime
Chad A. Middleton, Ethan Stanley
We examine the time evolution of the five-dimensional Einstein field equations subjected to a flat, anisotropic Robertson-Walker metric, where the 3D and higher-dimensional scale f…
Solutions of Higher Dimensional Gauss-Bonnet FRW Cosmology
Keith Andrew, Brett Bolen, Chad A. Middleton
We examine the effect on cosmological evolution of adding a Gauss-Bonnet term to the standard Einstein-Hilbert action for a (1 + 3)+ d dimensional Friedman-Robertson-Walker (FRW) m…
