Design and initial results from the "Junior" Levitated Dipole Experiment
Craig S. Chisholm, Thomas Berry, Darren T. Garnier +43
OpenStar Technologies is a private fusion company exploring the levitated dipole concept for commercial fusion energy production. OpenStar has manufactured a new generation of levi…
Excising Curvature Singularities from General Relativity
Alex Simpson
This thesis operates within the framework of general relativity without curvature singularities. The motivation for this framework is explored, and several conclusions are drawn wi…
General-relativistic thin-shell Dyson mega-spheres
Thomas Berry, Alex Simpson, Matt Visser
Loosely inspired by the somewhat fanciful notion of detecting an arbitrarily advanced alien civilization, we consider a general-relativistic thin-shell Dyson mega-sphere completely…
Constant- geodesics in the Painleve-Gullstrand form of Lense-Thirring spacetime
Joshua Baines, Thomas Berry, Alex Simpson +1
Herein we explore the non-equatorial constant- ("quasi-circular") geodesics (both timelike and null) in the Painleve-Gullstrand variant of the Lense-Thirring spacetime recently…
Geodesics for the Painleve-Gullstrand form of Lense-Thirring spacetime
Joshua Baines, Thomas Berry, Alex Simpson +1
Recently, the current authors have formulated and extensively explored a rather novel Painleve-Gullstrand variant of the slow-rotation Lense-Thirring spacetime, a variant which has…
Astrophysically viable Kerr-like spacetime -- into the eye of the storm
Alex Simpson, Matt Visser
We analyse a rotating regular black hole with asymptotically Minkowski core. This Kerr-like geometry possesses the full "Killing tower" of nontrivial Killing tensor, Killing-Yano t…
