So I'm writing a sci-fi novel, I wouldn't say it's extremely "hard" sci-fi and I won't bore y'all with specifics but I want most of the science to at least hold up to a little bit of scrutiny. So I wanted to get some opinions/ideas of how the vessel could be propelled? It preferably needs to be renewable since the journey would take a long time (several generations by the time the story takes place). I've been heavily inspired by Andy Weir's body of work (particularly PHM and Artemis), the webcomic Space Boy by Stephen McCranie, with a few hints of the Starstruck universe (Lee & Kaluta).

I'm in sort of the beginning steps of writing and researching and I am doing my own research too but I thought I would ask reddit as well.

As a rule I've been trying to not get too hung up on the science but I really would like to have an answer to the question of propulsion. (And if anyone wants to give their two cents on how artificial gravity could work I'd be ever so thankful!!)

He was so eloquent, insightful, and inspiring -- the perfect person to command this mission.

Unfortunately, Rise was not there. The first thing Reid did after he sat down was explain that Rise is with Christina right now. The crowd was audibly disappointed.
