Scientists Unveil New Multiverse Model: T2dS Wedge Holography Explained

In a new development, researchers Sergio E Aguilar-Gutierrez and Filip Landgren have proposed a novel model that sheds light on the existence of multiple universes within our own universe. Dubbed T2dS wedge holography, this innovative framework attempts to explain the intricacies of the multiverse by cutting off empty AdS d1-space with accelerated dS d-space universes at a finite AdS boundary cutoff.

The model’s intricate construction involves gluing together multiple copies of this configuration in a periodic manner, allowing for the study of entanglement entropy and its implications for quantum cosmology. This pioneering work has far-reaching implications for our understanding of the multiverse and its properties, offering new insights into the nature of reality itself.

A New Multiverse Model: T2dS Wedge Holography

The concept of a multiverse has been a topic of interest in the scientific community for quite some time. Recently, researchers Sergio E Aguilar-Gutierrez and Filip Landgren have proposed a new model that attempts to explain the existence of multiple universes within the framework of T2dS wedge holography.

In this model, the authors propose that empty AdS d1-space is cut off by a pair of accelerated dS d-space universes at a finite AdS boundary cutoff. This cutoff is treated as a T2-deformation in the holographic dual and one in the AdS interior, denoted as the IR brane. The construction of this model is referred to as T2dS wedge holography.

The authors then periodically glue together several copies of this configuration along the UV cutoff and the IR branes. This process provides the model with dynamics similar to those of near Nariai black holes used in other multiverse toy models. The researchers specialize to d=2 and add dS JT gravity as an intrinsic gravity theory on the IR branes.

Understanding T2dS Wedge Holography

T2dS wedge holography is a novel approach to understanding the multiverse, which involves cutting off empty AdS d1-space with a pair of accelerated dS d-space universes at a finite AdS boundary cutoff. This process is treated as a T2-deformation in the holographic dual and in the AdS interior.

The authors propose that this model can be used to study the entanglement entropy with respect to a finite cutoff observer who finds a Page curve transition due to an entanglement island connecting the UV cutoff and IR brane. This process involves the coarse-graining of information outside the causally accessible region to the observer.

In essence, T2dS wedge holography explicitly realizes entanglement between IR and UV degrees of freedom encoded in the multiverse. The researchers propose that this model can be used to study the dynamics of near Nariai black holes and provide insights into the nature of the multiverse.

Coarse-Graining Information in the Multiverse

Braneworld Multiverse Model

The braneworld multiverse model is a theoretical framework that attempts to explain the existence of multiple universes within the context of string theory. The researchers propose that T2dS wedge holography can be used as a tool to study the dynamics of this model.

In this model, the authors propose that gravity on a 1D-dimensional antide Sitter AdS d1-space region bounded by a pair of end-of-the-world ETW branes is dual to a CFT d1-theory living on the interception between the branes. This is realized within the Karch-Randall KR braneworld models.
