DIGITAL ORIGIN OF COSMIC INFLATION
Modern Physics Letters A, 2010Assuming our physical universe processes and registers information to determine its dynamical evolution, one can put serious constraints on the cosmology that our universe can bear, in particular, the origin of cosmic inflation. The universe evolves to gain her computation capacity which is linear in time t. On the other hand, the growth in content of

Cosmic inflation without inflaton
International Journal of Modern Physics D, 2019We propose a novel explanation for universe’s inflationary period. We argue that when the Einstein–Hilbert action is supplemented by an infinite tower of higher-curvature terms — selected order by order by the criterium that they give rise to a well-posed cosmological evolution — the usual Big Bang characteristic of Einstein gravity is replaced by a ...

Cosmic inflation and cosmic string
International Journal of Theoretical Physics, 1992We discuss the evolution of inhomogeneous space-time with a spinning fluid in higher dimensions. Using these evolving solutions, we explain cosmic inflation and the formation of a gravitational nontopological cosmic string.

Inflation can save cosmic strings
Physical Review Letters, 1989A new scenario of cosmic strings is presented which is free from the gravitational-radiation constraints imposed on their line density by the primordial nucleosynthesis and the timing data of a millisecond pulsar. In this scenario the phase transition is induced nonthermally during the inflation so that it is not necessary to assume Friedmann-Robertson-

Cosmic inflation mystery deepens
New Scientist, 2018The heat death of the universe is coming for people, but they don't know when. The cosmos is expanding, and the speed of that inflation is measured by a value called the Hubble constant. They have two ways to determine this rate, and they return different values, leaving cosmologists at an impasse.

Particle creation, inflation, and cosmic isotropy
Physical Review D, 1991Within the framework of homogeneous models of the Universe, inflation provides the simplest explanation for the present cosmic isotropy, and a Bianchi type-IX (mixmaster) model is the least prejudiced guess we can make about the state of the Universe before the inflationary phase.
