TED-ED: How fast are you moving right now? - Tucker Hiatt

The video explores the concept of motion, emphasizing that speed is relative and depends on the reference frame. It discusses how astronauts measure speed relative to different points, like the launchpad or Earth's center. The video introduces Galilean relativity, explaining that absolute speed doesn't exist. It highlights that space is not a substance, making motion relative. However, changes in speed and rotation are absolute and measurable. The video encourages critical thinking about perceptions of motion, inspired by Einstein's insights.
