The Expanse is a TV show based upon a series of books by James S. A. Corey. It's won a great deal of praise for its 'gritty realism', portraying life in the solar system 300 years from now. I got a lot of questions about how realistic the spacecraft were in the show, whether physics allowed for engines with the performance demonstrated by the spacecraft, so let's do the math.
