I used to wonder the same when I was 5. If I dropped something in the back of a car going 60 mph, why was it not immediately pressed against the seat back? I didn't get my answer until I was a teen when I read popular books about relativity. It's understandable that an adult not into science might wonder the same thing but once explained to them, it should be clear. If it is not, they do NOT require our help. They require the help of a neurosurgeon.

Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
