Contra views on the technologyEdit

Based on previous experience in these areas, I have to assume that adding a section on the implausibility of several of the tech features in the novels would quickly be marked as OR. However these are the points you could raise:

  • Despite the "efficiency" touted for the Epstein drive it still has issues. Exhaust velocity is on the order of 5% of the speed of light for the journeys described. Power requirements exceed the entire output of the human race today, even for small ships.
  • Spinning up asteroids would almost certainly tear them apart. Anything on the surface would be moving at more than escape velocity. Even if they could hang together, the pressures within the rock would make it impossible to keep caverns open.
  • Many distances are underestimated. Jupiter's moons are further apart than the Earth and Moon even at close approach, but the writing implies much shorter distances and the need to hide behind them. If you can get that far away quickly, you don't need to hide.
  • Journey times are often overestimated. The 1g drive eats up distance: time to 40 AU is 18 days. Yet the trip to the Ring takes weeks when it's only 21 AU from the Sun. That's about a 12 day trip.
  • A 1-kilometer ship accelerating at 1g is basically a 1000 meter skyscraper with all the same engineering challenges. Nobody in their right minds would build one.
  • Hitting Eros with a ship, even one a kilometer long, is not going to knock it into the Sun. Doing that requires you to hit the asteroid hard enough to cancel almost its entire orbital velocity. Eros has a mass of 6.69 trillion tonnes and is moving at nearly 25 km/s. A million tonne spaceship would have to be moving faster than the speed of light to have enough momentum to do the job.
  • There's a throwaway line in the first book where Epstein's prototype ship, still accelerating, is still visible in telescopes. In fact constant acceleration will get you close to the speed of light in 1 to 10 years, depending on the acceleration. After over a century, the ship would be beyond the closer stars.

  • Those are neat points. You should find them in a published reference (someone other than you must have noticed) then add them to the article.--Jim in Georgia Contribs Talk 02:43, 20 September 2015 (UTC)
Currently the article says "the series handles technology in realistic way", with no sources at all. Maybe that could be dialled back, though it probably is less unrealistic than a lot of SF. However, whether the above points are correct or not, they certainly are WP:OR. It's not for editors to nitpick the plausibility of a fictional story. (talk) 18:33, 26 November 2015 (UTC)


"The Expanse is set in a future in which humanity has colonized much of the Solar System, but does not have the means to travel to other systems." That should read The Expanse is set in a future in which humanity has colonized much of the Solar System, but does not have the means to travel to extra-solar systems. or other planetary systems. aajacksoniv (talk) 19:17, 6 March 2016 (UTC)

Babylon's Ashes: publication dateEdit

I changed the publication date to June 2016, with two supporting refs from the publisher.[1][2] Someone else has changed it to November 2016 because that's what Amazon have as their release date. I think the publisher is a better source than a book retailer. (talk) 20:50, 2 May 2016 (UTC)

Orbit appear to have different publishing dates for UK and USA. UK (Little Brown) is June, USA (Hachette) November82.1.16.12 (talk) 09:48, 3 May 2016 (UTC)

It would be nice to have simple plot summaries of the novels.Edit

I've read the first five, and when talking with friends who are starting the series I sometimes forget which is which. I was hoping to see plot summaries here, but there are not any. It would be great to add them.
