Creating a Universe from Nothing as an Alternative to the Cosmological Principle

Philip D. Mannheim, Daniel A. Norman, Tianye Liu

In the cosmological Robertson-Walker geometry required of the cosmological principle both the Weyl tensor $C^{μ λ ν κ}$ and the Bach tensor $W^{μν} = [2 \nabla_{κ} \nabla_{λ} - R_{λκ}] C^{μ λ ν κ}$ …

Exact solution to perturbative conformal cosmology from recombination until the current era

Asanka Amarasinghe, Tianye Liu, Daniel A. Norman +1

In a previous paper (P. D. Mannheim, Phys. Rev. D 102, 123535 (2020)) we studied cosmological perturbation theory in the cosmology associated with the fourth-order derivative confo…
