Meme Debunk Cards

This page provides short, shareable debunk cards. Each card is written so it can become a meme caption, social post or discussion prompt. 
 Card: “Earth Spins Too Fast” 
 Claim: Earth spins at about 1,670 km/h at the equator, so we should feel it. 
 Reply: You feel acceleration, not steady speed. The acceleration from Earth’s rotation is tiny because the radius is enormous. 
 Caption: “Speed gets the headline. Acceleration does the physics.” 
 Card: “Water Cannot Curve” 
 Claim: Water always finds its level, so oceans cannot curve. 
 Reply: Level means perpendicular to gravity. On Earth, gravity points toward the center, so the ocean can be locally level and globally curved. 
 Caption: “Level is local. Gravity is global.” 
 Card: “NASA Invented the Globe” 
 Claim: The globe depends on modern space agencies. 
 Reply: Ancient astronomers, sailors and surveyors had already measured Earth’s shape long before rockets existed. 
 Caption: “NASA didn’t invent shadows, ships or geometry.” 
 Card: “No Curve in Photos” 
 Claim: Horizon photos look flat. 
 Reply: Local horizons are subtle because Earth is huge. Photos also depend on altitude, field of view and lens distortion. Use measurements, not vibes. 
 Caption: “A wide planet makes a quiet curve.” 
 Card: “Antarctica Is an Ice Wall” 
 Claim: Antarctica is not a continent; it is the boundary wall around the flat Earth. 
 Reply: Antarctica is mapped, crossed, studied, photographed, and visited by researchers and tourists. Its coastlines, interior routes, time zones, and southern sky observations fit a continent on a globe, not a circular wall around all oceans. 
 Caption: “A continent with research stations is doing a lot of work for a wall.” 
 Card: “They Fake All the Images” 
 Claim: Space images are fake, so the globe is fake. 
 Reply: The globe does not depend on images. Shadows, stars, eclipses, navigation, surveying, time zones, and gravity measurements already point to the same shape. 
 Caption: “Delete every space photo. The geometry stays.” 
 Card: “Just Trust Your Eyes” 
 Claim: The Earth looks flat, so it is flat. 
 Reply: Your eyes are excellent locally. Planetary scale requires measurement. The same horizon that looks flat also hides distant objects bottom-first. 
 Caption: “Your eyes are local. Earth is large.”
