متن کاملThe Anamorphic Universe the Anamorphic Universe
We introduce “anamorphic” cosmology, an approach for explaining the smoothness and flatness of the universe on large scales and the generation of a nearly scale-invariant spectrum of adiabatic density perturbations. The defining feature is a smoothing phase that acts like a contracting universe based on some Weyl frame-invariant criteria and an expanding universe based on other frame-invariant ...
متن کاملPyrotechnic Universe
One of the central points of the ekpyrotic cosmological scenario based on Hor̆ava-Witten theory is that we live on a negative tension brane. However, the tension of the visible brane in HW theory, as well as in relevant cases of non-standard embedding, is positive. To make this scenario realistic one must solve the problem of the negative cosmological constant on the visible brane and fine-tune ...
متن کاملStationary Universe
If the Universe contains at least one inflationary domain with a sufficiently large and homogeneous scalar field φ, then this domain permanently produces new inflationary domains of all possible types. We show that under certain conditions this process of the self-reproduction of the Universe can be described by a stationary distribution of probability, which means that the fraction of the phys...
متن کاملEvolution of Information and Complexity in an Ever-Expanding Universe
Using the usual definitions of information and entropy in quantum gravity and statistical mechanics and the existing views about the relation between information and complexity, we examine the evolution of complexity in an ever expanding universe.
