Power to the pen!
Well, I have brainstormed it several times and I can't pick which one I like most. I thought I'd like to write a short story about the subject, but the more I think the more I wonder if it might be novel-worthy. It's all a question of which form would be the right one, you know? Arthur C Clarke once wrote that The Sentential is very different from the novel 2001 but it's often called an "expanded" version. My story is about a time-traveler going back to the past, learning something that shakes his worldview, and reporting it in the present only to find that his superiors want to suppress what he's found because they fear the truth. This means that my character is a highly sophisticated human. Is a short story enough to demonstrate how much of an impact such an experience would have on his life? I thought so, but some of my favorite novels explore their ideas much more deeply.What is it specifically that's causing you doubt? Could you sit down for a fifteen minute brainstorm session where the point is just to lay out what you think might be wrong, and what the solution might be? Sometimes that's all it takes to clarify things and get you back on track.
I don't even know if I'm making sense...I might just be tired.
