Superstring theory suggests a new cosmology whereby a long inflationary phase preceeded a non singular big bang-like event. After discussing how pre-big bang inflation naturally arises from an almost trivial initial state of the Universe, I will describe how present or near-future experiments can...
Pre-Big-Bang Requires the Universe to be Exponentially Large From the Very Beginning We show that in a generic case of the pre-big-bang scenario, inflation will solve cosmological problems only if the universe at the onset of inflation is e... N Kaloper,A Linde,R Bousso - 《Physical ...

1. Beyond Big Bang and Planck scale Eighty years after the Big Bang hypothesis formulated by Georges Lemaître [10], WMAP and Planck may allow to explore the origin of the Universe, as well as the structure of matter and space-
universe originated from the big bang of the "super-micro black hole".Recently it is put forward that the expanding universe originated from the big bang of the "pre-universe",by which the theory of the big bang of the point is denied,and both the theories of the "pre-universe"and our...
Galaxy-formation models allowing pregalactic activity and their implications for the hidden mass of the universe are discussed, summarizing the findings of Carr and Rees (1983) and Kashlinsky and Rees (1983). Topics examined include the size of the first objects in a baryon-dominated universe; ...
Even assuming that part of this CMB B-mode polarization reallycorresponds to the early Universe dynamics, its interpretation in terms ofinflation and primordial gravitational waves is not the only possible one.Alternative cosmologies such as pre-Big Bang patterns and the spinorialspace-time (SST) ...
