Someone in a different thread brought up Generations, and it got me thinking....
People didn't take much issue with the concept of The Nexus, a basically magical energy ribbon that travels through space and is a gateway to a realm where all you're fantasies come true, you never age, that you can travel throughout, and even leave, using simply a thought.....
But the concept of a subspace fold opening up and producing an improbability field, where music is played and people are involuntarily made to sing show tunes..... that's to big a pill to swallow?
Just a thought.
