About this quiz

What you’ll practice

This quiz sharpens your ability to judge common space claims using basic astronomy and physics ideas. You’ll learn to recognize misleading wording and separate movie logic from real-world evidence.

Each question is True/False in a 4-option multiple-choice format, and there’s no timer—take your time and think it through.

Difficulty and question settings

Difficulty is mixed on purpose: easier items cover well-known facts (like gravity and the Moon), while tougher ones lean on less-intuitive topics (like vacuum behavior, orbits, and radiation). Choose how many questions you want to play and select a difficulty level to keep the session quick, steady, or more challenging.

Watch for absolute words like “always” or “never,” which often signal a myth
Don’t confuse “no gravity in space” with “microgravity in orbit”
Remember that sound needs a medium—space is (mostly) a vacuum
Separate “weightless” from “massless” when judging astronaut claims
Be careful with scale: distances, sizes, and temperatures are easy to misjudge

Common pitfalls (and how to avoid them)

Many myths sound plausible because they mix one true detail with a wrong conclusion; focus on the full statement, not just a familiar keyword. If you’re unsure, think in terms of cause and effect (gravity, motion, pressure, heat transfer) rather than trivia.

Tips to improve your score

Replay with a different difficulty setting and compare which topics trip you up most. Reviewing explanations you already know can also help you spot trick phrasing faster on the next run.
