Section 3: Here are the discussion questions for the video:
1) How did Newton define space? Why was his definition so groundbreaking at the time?
2) What is special about the speed of light? Give an example that proves your point.
3) How did Einstein use the speed of light to redefine space? How did Einstein's definition of space differ from Newton's?
4) How did Einstein use his new idea of spacetime to explain how gravity holds the moon in orbit around the Earth?
5) Do you think the period in history and the environment Einstein grew up in played a role in his ability to complete his 'thought experiments'? Why or why not?
