The Norse told tales of the rainbow bridge.  Many religions have rivers we take into the otherworlds.  And now we have hyperspace.  You know many describe it as a river of gravity?  It flows from star to star, binding the galaxy together in currents of gravity we see as every color of the…rainbow.  The poets describe it in so many colorful ways, using words and emotions to embellish it.  But does it really need that embellishment?  Or is it amazing enough on its own?
