And looking from the
other end of time, long after proton decay plus expansion of the universe reduced all matter to electron-positron plasma, it is possible to imagine "matter" and, conceivably, living creatures, made out of electron-positron pairs. IIRC, each such electron-positron "atom" (also known as positronium) would be larger than current visible universe, and would complete one revolution in 10
114 years. From the viewpoint of such positronium beings the entire era of stars, planets, and black holes[1] is just a detail of Big Bang -- an unimaginably short burst of complexity among exotic ephemeral particles.
[1] Since all black holes, even galaxy-mass ones, will evaporate via Hawking radiation in far less time than one revolution of a positronium atom
