Inflasi Dan Anisotropi Alam Semesta Oleh Elektrodinamika Nonlinear
ABSTRACT The Big Bang Theory explains how universe formed. After Big Bang, universe accelerated by a scale factor of a(t). However, from Big Bang period until now, standard cosmology has some problems in explaining the evolution of universe, such as monopoles, horizons, and flatness. To solve this problem, a model of inflation at the early time of universe is needed. Inflation theory expla…
