  • The Hitchhiker’s Guide, you likely won’t be able to finish each of the 5 books in the trilogy in a day but it’s something you can read a hundred times and find a new witty joke somewhere, much like all the Discworld novels.

    The Expanse is another that you could burn through a book a day but wow it’s a hell of a story and worth taking your time on each character’s perspective, Outlander is also a good one for the same reasons but those are 1k pagers







  • Chemical/liquid rockets and compressed gas thrusters are two different things with different functions. You’re right that lighting a fire in space won’t do much but make a cool firework. A thruster doesn’t so much push against space as it does nudge the ship in the other direction. Newton’s 3rd law and all that except the second “body” in this case isn’t something physical outside the ship but rather the force of the the gas leaving the thruster nozzle causing a recoil.
