Project Description

Number of awards:

1

Start date and duration:

September 2019 for 3.5 years.

Overview:

Research in string theory has shown that gravity is holographic: certain gravitational theories have an equivalent description in terms of a quantum theory, without gravity, living in one spacetime dimension less. Representing our sharpest understanding of quantum gravity to date, holography sheds new light on the fundamental problems of cosmology, from resolving the big bang singularity to explaining the pattern of perturbations visible in the temperature and polarisation of the cosmic microwave background.

According to the theory of inflation, these perturbations began as microscopic quantum fluctuations in the matter density and geometry of spacetime, which were subsequently stretched to macroscopic scales by the accelerated expansion of the universe. While the dynamics of this process can be constrained through measurements of the cosmic microwave background, it remains poorly understood from a fundamental theoretical perspective. This project will use holography to recast the four-dimensional early universe as a three-dimensional quantum field theory. Novel holographic approaches will be developed to explore the origin and symmetries of the primordial perturbations, building on recent advances in conformal field theory. Ultimately, the goal is to identify distinctive observational signatures of holography that can be tested through future cosmological observations.
