Cosmic Evolution in Generalised Brans-Dicke Theory [PDF]
, 2002 We have studied the Generalised Brans-Dicke theory and obtained exact solutions of a(t),phi(t),and omega(t) for different epochs of the cosmic evolution .We discuss how inflation,decceleration,cosmic acceleration can result from this solution.The time ...

Cosmic Evolutionary Philosophy and a Dialectical Approach to Technological Singularity
Information, 2018 The anticipated next stage of human organization is often described by futurists as a global technological singularity. This next stage of complex organization is hypothesized to be actualized by scientific-technic knowledge networks.

Refueling the Magic Furnace: Kilonova 2017 Rewrites the Story of Element Origins
Journal of Big History, 2018 For more than half a century, we have understood element creation in the stars—described in Marcus Chown’s colorful image as “the magic furnace.” From 1958 until 2017, supernova explosions were thought to be the primary site of element creation above ...

Cosmic Rays From Cosmic Strings
, 1994 It has been speculated that cosmic string networks could produce ultra-high energy cosmic rays as a by-product of their evolution. By making use of recent work on the evolution of such networks, it will be shown that the flux of cosmic rays from ...

Cosmic Neutron Star Merger Rate and Gravitational Waves constrained by the R Process Nucleosynthesis
, 2015 The cosmic evolution of the neutron star merger (NSM) rate can be deduced from the observed cosmic star formation rate. This allows to estimate the rate expected in the horizon of the gravitational wave detectors advanced Virgo and ad LIGO and to compare

The Cosmic Evolution of Quasars [PDF]
Highlights of Astronomy, 2005 AbstractThe form of the quasar luminosity function and its redshift dependence to z~1 has long been established; powerful evolution is required so that by z=1 there is an increase of order 102 – 103 in the space density of the most luminous sources. However it is more difficult to deduce the form of the LF at high redshifts.

Comparison of numerical solutions for Q^2 evolution equations [PDF]
, 2004 Q^2 evolution equations are important not only for describing hadron reactions in accelerator experiments but also for investigating ultrahigh-energy cosmic rays.
