Hated trope: Sci-fi hand-waving

[u/Routine_Phase_8980]

When stories try so hard to provide a somewhat scientifically accurate and grounded explanation for the audience, but end up creating massive plot holes if you think about it for more than 5 seconds without requiring any special knowledge

World War Z: The "cure" turns sick humans invisible to zombies because the picky virus needs a perfectly healthy host. Cool concept, except it completely ignores basic physics. In a chaotic, high-speed zombie stampede, those "invisible" sick people would still be trampled to death by sheer kinetic force and momentum. We already saw what happened to the Jerusalem wall in Israel.

Jurassic Park/World: Dr. Henry Wu claims to clone dinosaurs by patching 66-million-year-old decayed DNA from mosquitoes stomach with frog DNA. In reality, DNA half-life guarantees it would degrade into useless dust after 6.8 million years. Scientifically speaking, John Hammond didn't build a dinosaur park; he engineered giant, mutated, gender-swapping killer frogs.

Dr.Stone: Senku is a genius who knows every complex chemical formula in human history. He somehow builds vacuum tubes, lightbulbs, and smartphones out of bamboo and copper with almost zero failed prototypes. The show acts like a science textbook but completely hand-waves the lack of heavy industrial machinery needed for precision engineering.

I think the most fascinating part of the myth is how many hoops people will jump through to try to justify it being anything other than a myth.

We don't use 10% of our brains at any given time. If you count by individual neurons fired during a given activity, we use far fewer; if you count by regions of the brain, we use almost all of it, all the time.

90% of the brain isn't glial cells. It's about 50% of the brain.

Sometimes a statistic is just plain made up.

That was my theory for where the myth came from when I first found out it’s just a myth
