Nonflat time-variable dark energy cosmology
Anatoly Pavlov, Shawn Westmoreland, Khaled Saaidi +1
We generalize the time-variable dark energy scalar field model (CDM) to nonflat space. We show that even in the space-curvature-dominated epoch the scalar field solution is…
Optical black holes and solitons
Shawn Westmoreland
We exhibit a static, cylindrically symmetric, exact solution to the Euler-Heisenberg field equations (EHFE) and prove that its effective geometry contains (optical) black holes. It…
A note on relativistic rocketry
Shawn Westmoreland
In the context of special relativity, we discuss the specific impulse of a rocket whose exhaust jet consists of massive and/or massless particles. This work generalizes previous re…
Are Black Hole Starships Possible
Louis Crane, Shawn Westmoreland
We investigate whether it is physically possible to build starships or power sources using the Hawking radiation of an artificial black hole as a power source. The proposal seems t…
On the principle of relativity and electrostatics in a flat spacetime with a compact spatial dimension
Shawn Westmoreland
We study a flat spacetime with a compact spatial dimension and dispute the claim of Bansal, Laing, and Sriharan that a local experiment can determine whether or not an inertial obs…
