Despite overwhelmingly contradictory evidence I still happen to run into people with the belief that the earth is hollow. (Much more so recently, due to the hollywood movie.) Can anyone here unfalsify this hypothesis?
Well for one thing, if the earth were hollow, there would be no magnetic field around the earth, because it is in fact the exact center of the earth that is a liquid metallic iron swirling around which generates the field, without which we would be cooked by the sun, no shield against hard radiation from solar storms. Another thing, seismic sensors delve deep into the earth and would easily detect a hollowness but in fact, the analysis shows a liquid metal core.
