Well, obviously. It amazes me how there're still people who think the Earth is flat! Besides the obvious visual proof (you can see the curvature in certain situations, you can see how all celestial bodies are spherical, etc.), there are some logical reasons, such as being possible to travel the world in a straight line, doing a perfect circle and ending up just were you started. How can they explain that, if the Earth is flat?!
Oh, the irregular direction of gravity theory:
How interesting...
@Davros , I'm always learning new stuff thanks to you. ^_^
Numbnuts above has worked out the bubble is centered when at right angles to gravity
his mistake is he thinks the direction of gravity is in picture A and not picture B
