Unpredictability of the Fate of Accelerating Universe

The acceleration of the universe has been confirmed through various cosmological observations since 1998. Nevertheless، there are many models proposed to explain this acceleration and there is no broad agreement on the fact. A concordance model titled “ΛCMD” suggests that the energy of the vacuum space، with a negative pressure، is the origin of the universe acceleration. However the nature of this energy is unknown، and so it is called “Dark Energy”، and we have only a phenomenological equation of state (EOS) for it. The cosmologist Lawrence M. Krauss’ thesis، based on a specific value of EOS parameter، predicts a static universe of our local supercluster surrounded by a void، in the future. According to Krauss، the late time intelligentswill not have any access to the pillars of the modern cosmology، and so the “End of Cosmology” will be expected. This paper surveys Krauss’ thesis and examinesits assumptions and consequences. An unavoidable uncertainty in the prediction of the fate of accelerating universe is vindicated.
