Misconceptions & Reasoning
📋 What it is
Good astronomers test "obvious" ideas against evidence — many space beliefs turn out to be wrong.
🗣️ Coach says
Space is full of ideas that FEEL right but aren’t. Summer isn’t "Earth closer to the Sun"; stars don’t really twinkle (our air wobbles their light); space isn’t a total vacuum of nothing. Reasoning means checking the claim against evidence, not against your gut.
🧠 Memory hook
Feels-true ≠ is-true. Check the evidence before you believe the "obvious".

What's a black hole's favorite game?
Anything — it sucks you in no matter what!
😲 Whoa!
The North Star (Polaris) won’t stay our pole star forever — in ~12,000 years Earth’s slow wobble makes bright Vega the new "North Star".
✅ Quick check: A friend says stars twinkle because they flicker on and off. What’s actually happening?
Say your answer out loud first — then reveal.
Stars shine steadily; our moving ATMOSPHERE bends their light, so the light seems to twinkle to us on the ground.
Twinkling (scintillation) is caused by Earth’s atmosphere, not the star itself.

Write down one thing you "know" about space, then ask: how could someone TEST that? Is it actually true?
