A Mcguffin is a plot device, and it allows for the suspension of the normal limitations of reality. Typically a story needs at least one such Mcguffin. Anything beyond that and you look cartoony.
Story-telling complexity and creative license may be attributed to acceptance level and sophistication of the audience in the era for which the fiction was introduced.
Examples in other science fiction might include:

Star Wars Universe Edit

  • artificial gravity
  • hyperspace drives
  • the force and midichlorians
  • light sabers and kyber crystals
  • tractor beams

Star Trek Universe Edit

  • artificial gravity
  • the warp drive,
  • inertial dampers,
  • the teleporter technology
  • cloaking devices
  • tractor beams
  • real-time communications on electromagnetic carrier waves between points which are many light-minutes or light-hours apart in distance.
  • symbiotes (e.g. Trills)
  • empaths (e.g. Betazoids)
  • shape shifters (e.g. Changlings)

Spoilers ahead.

Solid Core Nuclear Core Rocket Engine- 500-1100

Liquid Nuclear Core Rocket Engine- 1300-1600

Gas core nuclear rocket engine-3000-7000

What ships on The Expanse have- 1,000,000 (ability to do 10g burns for long periods.)

Space Juice Edit

It is not specifically named but the use of steroids and meds to counteract the effects of growing up in weightless seems impossible. how do you grow muscles when nothing weighs anything?

In contrast a drug that fights cancer sounds quite reasonable.

protomolecule Edit

the alien technology at the center of the story
