A truly relevant premise in our time, here are my suggestions:
1. Can protag “inventor” change to an e.g., SpaceX aerospace engineer? As I write, NASA aerospace engineer Harold G. White works to develop faster-than-light travel aka a Warp Drive.
2. Change faster-than-light to warp drive to tractor beam more, Sci-fi nerds, to your premise 😉
3. Obstacles are required, but using the word is vague, you need an e.g., baddie nation out to get this tech OR something personally insurmountable – as your obstacle.
4. The word “attempts” turns your premise into a wet noodle. “Try not. Do or do not. There is no try - Yoda”
5. Finally, as a human collective, wherever we go “Mars” there will be war. Ask yourself, how would YOU attempt to change or prevent to achieve this utopia, then distill that down as a compelling goal.
Hallucigenia, these are only suggestions - this is your story.
Happy New Year!
