Just like when you circumnavigate, the route is always a circle from east to west, it never crosses from north to south because that route does not exist. But since you're an expert, can you tell me which is the barycenter of the earth? Or how is the mass of the sun calculated? or because there is no experiment by direct scientific method that shows that the water sticks to the outside of your container?

PD: The earth is flat, like your brain.
