RAYS show a slight preference as to their directionality.
A notable departure from this general pattern consists of three pairs of events whose directions of arrival are quite close, less than 2.5 degrees. And of these, two pairs are located within 2 degrees of the supergalactic plane, defined roughly by the agglomeration of bright nearby galaxies in the northern hemisphere. He points out that some communication mechanisms could be more robust in weathering a noisy environment. Landauer's argument builds on his own work in the 1960s and that of IBM physicist Charles Bennett who previously suggested that under certain conditions the computation process itself can proceed without energy dissipation. Although Landauer admits that implementing his proposed scheme may be impractical, his argument is intended to show that no fundamental limits of minimum energy expenditure for communication necessarily exist.
