Abstract: It has, quite recently, become fashionable to study a certain class ofholographic-inspired models for the dark energy. These investigations have,indeed, managed to make some significant advances towards explaining theempirical data. Nonetheless, surprisingly little thought has been given toconceptual issues such as the composition and the very nature of the implicatedenergy source. In the current discourse, we attempt to fill this gap by the wayof some speculative yet logically self-consistent arguments. Our constructiontakes us along a path that begins with an entanglement entropy and ends up at aHubble-sized gas of exotic particles. Moreover, our interpretation of the darkenergy turns out to be suggestive of a natural resolution to thecosmic-coincidence problem.
