Sure, sure. That's why at 10000 feet, up in an airplane, the horizon is curved. Come on people, use your logical thinking brains please. The core of the earth has iron in it. A lot of iron. It has a plethora of other metals as well, hence the reason for polar magnetism and gravity. All the planets in the solar system stay in their places due to the magnetic forces that are caused from the ores and minerals in their cores. It is completely ludicrous to overlook the FACT, that we are a species based on these elements and minerals. I don't trust N.A.S.A. either, but I'm not going to jump on ignorant band wagons that go against all logic and science.
