摘要The observed acceleration of the present Universe is shown to be well explained by the holographic dark energy characterized by the total comoving horizon of the Universe (eta HDE). It is of interest to notice that the very large primordial part of the comoving horizon generated by the inflation of the early Universe makes the eta HDE behave like a cosmological constant. As a consequence, both the fine-tuning problem and the coincidence problem can reasonably be understood with the inflationary universe and holo-graphical principle. We present a systematic analysis and obtain a consistent cosmological constraint on the eta HDE model based on the recent cosmological observations. It is found that the eta HDE model gives the best-fit result Omega(m0) = 0: 270 (Omega(de0) = 0: 730) and the minimal chi(2)(min) = 542: 915 which is compatible with chi(2)(ACDM) = 542: 919 for the ACDM model.
