What's the sci-fi ideas do you wish someone would write about? For example, Stephen Hawking once said, "Imaginary time is like another direction in space. It's the one bit of my work science fiction writers haven't used because they don't understand it." What crazy ideas do you have? Have you ever ended up writing about something because no one else would? How did that go? How important is the premise in a sci-fi story to you versus the action, or the plot, or the character interactions?
