    "abstract": "The standard big bang cosmology has been greatly successful in explaining\nmany observational aspects of the real universe. However, two particular\ndiffficulties faced by it are the so-called ``horizon\u0027\u0027 and ``flatness\u0027\u0027\nproblems. By assuming that the recently found cosmic acceleration to be a\ngenuine and ever present effect, we show that, the resultant modified Friedman\nmodel is free from both the above referred problems, and there is no need to\ninvoke the additional ``inflationary\u0027\u0027 initial phase as a seperate ingredient.\nThe important cosmological milestones of the standard big babg cosmology (which\npredicts cosmic deceleration) like GUT symmetry breaking epoch or radiation\nmatter decoupling epoch may remain more or less unchanged in the modified\ncosmology in terms of redshift values. However, in terms of cosmic time $t$,\nall such epochs occur earlier as the universe becomes older in this case.",
