DEMISE/DEMI ~ Dark Energy Message Impelling Service Extranet
'Called DEMI for short, nearly all of the Five Galaxies messaging and news broadcasting travelled along its chain of galaxy-encircling, interlocking rings of dark matter tubes, empty of everything except dark energy. The energy, free of any other force, travels at ferocious FTL speeds, taking any packet of radio signals broadcast into it along with it.'
