Matching Radial Geodesics in Two Schwarzschild Spacetimes (e.g. Black-to-White Hole Transition) or Schwarzschild and de Sitter Spacetimes (e.g. Interior of a Non-singular Black Hole)
Wei-Chen Lin, Dong-han Yeom
In this article, we study the trajectory equations of the bounded radial geodesics in the generalized black-to-white hole bounce with mass difference and the Schwarzschild-to-de Si…
Explicit construction of Penrose diagrams for black hole to white hole transition with spacelike thin shells
Wei-Chen Lin, Dejan Stojkovic, Dong-han Yeom
In this article, we explicitly construct the coordinates associated with the Penrose diagram in spacetimes connected via a spacelike thin shell in the following two examples: the g…
Trouble with geodesics in black-to-white hole bouncing scenarios
Deog Ki Hong, Wei-Chen Lin, Dong-han Yeom
By utilizing the thin shell approximation, we investigate the behavior of radial timelike geodesics in a black hole to white hole bouncing scenario with a mass (de-)amplification r…
The Trans-Planckian problem in Tachyacoustic Cosmology
Wei-Chen Lin, William H. Kinney
We study Tachyacoustic models of cosmology, for which a scale-invariant perturbation spectrum is generated via superluminal sound speed instead of accelerated expansion, as in the…
Trans-Planckian Censorship and -inflation
Wei-Chen Lin, William H. Kinney
We propose a more general version of the Trans-Planckian Censorship Conjecture (TCC) which can apply to models of inflation with varying speed of sound. We find that inflation mode…
