Particle-theory and field-theory models of the early UniverseIn this paper, we use a known duality between expanding and contracting cosmologies to construct a dual of the inflationary flow hierarchy applicable to contracting cosmologies such as ekpyrotic and cyclic models. We show that the ...

We revisit a cyclic cosmology scenario proposed in 2007 to examine whether its hypotheses can be sustained if the underlying big-rip evolution, which was assumed there, is replaced by the recently ...

The calculated percentages of dark energy, dark matter, and baryonic matter and the calculated time for dark energy to start are in good agreements with the observed values. 展开 关键词: CYCLIC UNIVERSE MULTIVERSE Interuniversal Void String Theory COSMOLOGY Big Bang Inflation DARK Energy DARK ...
It’s a very messy universe out there, and if you don’t take every single source of error correctly into account, you can convince yourself of all sorts of things. Just because this particular signal is there doesn’t mean the underlying model — Penrose’s Conformal Cyclic Cosmology (CCC...
