“Do not look at stars as bright spots only. Try to take in the vastness of the universe.” -Maria Mitchell

The analogies between small-scale, living things and large-scale, cosmic entities are abundant: between a neuron and the Universe’s large-scale structure; between an atom and a solar system; between the stars in a galaxy and the atoms in a cell; between the cells in a living being and the galaxies in the Universe. It makes you wonder if, on a cosmic scale, some portion (or the whole) of the Universe could actually be alive and self-aware?

While we don’t yet know how to test for that, what we can calculate is the amount of information that a self-aware being does exchange, and compare that to the amount of information that could conceivably be mutually exchanged by cosmic entities on various scales. The conclusion is that while the entire Universe can’t do it, on timescales much longer than the present age of the Universe, individual bound galaxies, groups and clusters perhaps could.
