Moving from YMMV page; this is an in-universe example, not an audience reaction.

* NightmareFuel - In-universe example. The rogue star systems in interclan space[[labelnote:*]] lone stars and planets floating in the middle of nowhere[[/labelnote]] are enough to make the crew black the windows right away.

The starship ''Leonora Christine'' is supposed to carry its 50 colonists to a distant star. The journey should take 33 years, but due to TimeDilation at near-light speed, only 5 years will pass for the crew. Then things go to hell when the ship collides with a nebula (due to the mass of the ship and nebula at that speed, it's like hitting a solid object); the ship's decelerator system is damaged, so they can speed up (and steer) but can't slow down.[[hottip:*:They're on a one-way ride to wackiness!]] The ship will keep getting closer and closer to light-speed, reducing the passage of time onboard (their "Tau") to nearly zero. In the time it takes them to repair the damage and stop the ship, billions upon billions of years have passed and the universe is reaching the point of imploding (a "Big Crunch") and starting over with a new Big Bang.

** The [[{{Ramscoop}} Bussard engine]] which is used in this novel (and many others during the time period) doesn't really work as advertised.

The Bremsstrahlung generated as the gathered hydrogen "swirls down the drain" could (theoretically) be turned into electric energy, and that energy added to the exhaust to offset the Bremsstrahlung drag, although no such process could ever be 100% efficient.]]

* MohsScaleOfSciFiHardness - So hard it makes diamonds look like a fluffy pillow. Even the ship's engine is based on a real world theoretical engine that was proposed shortly before Anderson wrote the book. ** Unfortunately ScienceMarchesOn. The [[{{Ramscoop}} Bussard engine]] which is used in this novel (and many others during the time period) doesn't really work as advertised. In short, the enormous '''drag''' of collecting interstellar hydrogen limits the ramjet's speed to about 12% light-speed. *** There ''are'' a few proposed solutions to the drag problem, though they require technology that doesn't currently exist.

Missing from the scene is the [[https://en.wikipedia.org/wiki/Cosmic_microwave_background cosmic microwave background]], discovered at around the time the original short story was written. At the speed the ship was going, it would be blueshifted far enough into the gamma spectrum to kill people instantly from radiation poisoning. ** Despite the novel's hardness, Anderson still uses {{Handwavium}} in a few places. The molecular interpenetration anchors that secure a boat to the docks on Earth are pure fantasy. The scoop field operates by "seizing hydrogen atoms by their dipoles -- no ionization needed," for which no current scientific basis exists.

Even at the time the book was written, though, Anderson's cosmology didn't line up with real cosmology. He described the ''material'' in the universe falling inward to a single point in space (which he called a "monobloc"), and ''Leonora Christine'' flying around it in a circle. In the real Big Crunch model, though, it isn't the stuff inside the universe that infalls into a single point, ''spacetime itself'' contracts to a point. There would be no space outside the "monobloc" to fly around in. *** Even so, Anderson's handwave in the book still more or less applies: The characters have to hope that a single point is just an abstraction that makes the math easier, and the universe won't actually shrink quite as small as that. It's a rounding error in the size of the universe, but a million-mile rounding error makes all the difference for a spaceship in the vicinity.

Removing wick to Did Not Do The Research per rename at TRS.
* TimeDilation - It keeps increasing, to the point where years are going by for every second the ship experiences. Unfortunately, [[DidNotDoTheResearch he does it wrong]]. Time dilation is a distinctly tricky phenomenon to understand without digging deep in special relativity -- to a spaceship traveling close to the speed of light, the rest of the universe appears to be travelling past while the spaceship is stationary, therefore the spaceship would see time pass normally for itself and time pass more slowly for ''the rest of the universe''. Things would only change (and the effect become prominent) upon deceleration.
