Galaxies — Multiple Authors

With hundreds of billions of galaxies in the Universe and hundreds of billions of stars in most galaxies, the possibility of habitable planets other than our Earth is a certainty. When humankind spreads outward, as it must in order to survive, communication and interaction between galaxies must also reach unforeseen capabilities. Life in a distant future, where moving between galaxies is accomplished with ease, will be different…yet in many ways the same. Human interaction is a constant -- love, hate, trust, fear -- emotional qualities of life cannot change. Or can they? What will future humans be like? For that matter, could our cousins already exist and be waiting for us to contact them?
