Themes: Wormholes, Space, Nonfiction, Tween. Explore the science behind space-time and find out if wormholes offer a shortcut through galaxies and even allow humans to travel to a parallel universe and time travel. Red Rhino Books Nonfiction is the f

Using the fact that, for a broad class of Morris-Thorne wormholes, the maximum of the effective potential is located at the throat, we derive accurate analytic WKB expressions for the quasinormal modes and grey-body factors of various traversable wor

In a brane-world context in which our universe would be a four-dimensional brane embedded into a five-dimensional spacetime or bulk, wormhole geometries are induced on branes. In this article, the Morris-Thorne wormhole and the Molina-Neves wormhole

In this work, we studied the characteristics of wormholes with multiple throats/anti-throats in the context of general relativity. The presence of these structures is verified through the minima and maxima in the area of these wormholes. Using embedd

We show how certain types of magnetic asymptotically Anti-de Sitter Euclidean wormholes can catalyze the onset of inflation. These wormholes can be embedded as saddle point solutions of General Relativity coupled to the Standard Model, the inflaton b

We show for the first time that rotating wormholes are capable of emitting a Poynting flux in the process of accreting magnetized matter. To this end, we analyze the Damour-Solodukhin metric describing a Kerr-type wormhole and calculate the electroma
