2. Your car doesn't travel in a straight line, and you can measure...

...it's speed no? Throw a baseball, watch gravity pull it back to the ground. You can measure it's speed no?

8. Speed of light

was measured across a very short distance in a tunnel or pipe in Erie Pa. if I remember correctly.

There was no gravitational force to 'bend' it over that short a distance.

Now go ask this question in the Science Forum-get a correct answer.

But space/time is bent. :)

12. if a person don't speak correct english
