Dilaton cosmology and the Modified Uncertainty Principle.

In modern physical cosmology, the cosmological principle is the notion that the spatial distribution of matter in the universe is homogeneous and isotropic when viewed on a large enough scale.

In modern physical cosmology, the cosmological principle is the notion that the spatial distribution of matter in the universe is homogeneous and isotropic when viewed on a large enough scale, since the forces are expected to act uniformly throughout the universe, and should, therefore, produce no observable irregularities in the large-scale structuring over the course of evolution of the matter field that was initially laid down by the Big Bang.

Cosmology by definition is the branch of astronomy involving the origin and evolution of the universe, from the Big Bang to the future of the cosmos. What Is Cosmology? Definition & History.

Cosmology draws on many branches of physics to study the universe's history. And what it's found has forever changed how we understand our position in the cosmos. Isaac Newton's description of gravity often works in that realm too, but it treats space (and time) as a rigid and unchanging backdrop against which to measure events. Einstein's work showed that space itself could expand and contract, shifting the universe from stage to actor and bringing it into the fray as a dynamic object to study.

of cosmology, and he makes it clear that our knowledge and ignorance seem to be expanding in parallel. Stuart Clark offers a refreshing summary of what we think we know now and the long history of our learning to parent day concepts.

The author brings the subject up to 2015 with the obligatory new discovery combined with a fine history of cosmology, and he makes it clear that our knowledge and ignorance seem to be expanding in parallel. Since satisfying results have yet to turn up, Clark's book ends on a cliffhanger, but readers will be entirely pleased with the experience.

Physical cosmology is a branch of cosmology concerned with the studies of the largest-scale structures and dynamics of the universe and with fundamental questions about its origin, structure, evolution, and ultimate fate. Cosmology as a science originated with the Copernican principle, which implies that celestial bodies obey identical physical laws to those on Earth, and Newtonian mechanics, which first allowed those physical laws to be understood.

Of course a space-time by itself does not provide a full cosmology. To obtain interesting physics, gravity must of course be present, at least for intermediate scales

Of course a space-time by itself does not provide a full cosmology. To obtain interesting physics, gravity must of course be present, at least for intermediate scales. As explained in section ., spin 2 modes which could play the role of gravitons do indeed arise, however this needs to be re-examined carefully for the present Lorentzian backgrounds15. This may be reconciled noting that the mass terms for matter should in fact not arise from the bare matrix model but from spontaneous symmetry breaking as in the standard model, which would presumably lead to a consistent picture.
