# A principle to determine the number (3+1) of large spacetime dimensions

@article{Rama2007APT, title={A principle to determine the number (3+1) of large spacetime dimensions}, author={S. Kalyana Rama}, journal={Physics Letters B}, year={2007}, volume={645}, pages={365-368} }

Abstract We assume that our universe originated from highly excited and interacting strings with coupling constant g s = O ( 1 ) . Fluctuations of spacetime geometry are large in such strings and the physics dictating the emergence of a final spacetime configuration is not known. We propose that, nevertheless, it is determined by an entropic principle that the final spacetime configuration must have maximum entropy for a given amount of energy. This principle implies, under some assumptions…

The dynamics of a $$(3 + 1)$$(3+1) dimensional homogeneous anisotropic universe is modified by loop quantum cosmology and, consequently, it has generically a big bounce in the past instead of a…

Abstract We consider N -charge, intersecting brane–antibrane configurations in M theory which are smeared uniformly in the common transverse space and may describe our universe. We study the…

Spacetime Dimensionality from de Sitter Entropy

We argue that de Sitter universes with a small cosmological constant are entropically favored to have three spatial dimensions. The conclusion relies on the causal-patch description of de Sitter…

Relaxing to three dimensions.

The idea is that the Universe will naturally select among possible vacua through its cosmological evolution, and the configuration with the biggest filling fraction is the likeliest, and this idea is applied to the question of the number of dimensions of space.
