A Note on the Stability of the Dark Energy Model from Time Crystals
Laura Mersini-Houghton
In this note, we investigate the stability of the dark energy model from time crystals proposed in [1]. We emphasize two ingredients, the coupling of the scalar field to gravity, a…
On a Relation of Vacuum Energy to the Hierarchy of Forces
Stephon Alexander, Laura Mersini-Houghton
We investigate the relation between vacuum energy and the hierarchy of forces in habitable universes. The hierarchy of forces studied in \cite{fred} was bound by $\frac{α_G}α \le 1…
Is Eternal Inflation Eternal?
Laura Mersini-Houghton
In this paper we explore the relationship between the existence of eternal inflation and the initial conditions leading to inflation. We demonstrate that past and future completion…
Investigating Dark Energy with Black Hole Binaries
Laura Mersini-Houghton, Adam Kelleher
The accelerated expansion of the universe is ascribed to the existence of dark energy. Black holes accretion of dark energy induces a mass change proportional to the energy density…
Limitations of anthropic predictions for the cosmological constant : Cosmic Heat Death of Anthropic Observers
L. Mersini-Houghton, F. Adams
This paper investigates anthropic bounds on the vacuum energy . We first consider the possibility of cosmic observers existing at any random time (including the future) for cons…
Probing Dark Energy with Black Hole Binaries
Laura Mersini-Houghton, Adam Kelleher
The equation of state (EoS) of dark energy remains elusive despite enormous experimental efforts to pin down its value and its time variation. Yet it is the single most importa…
