I always speculated that the earth is infect both flat and round. I actually think that the earth might be infinite and that all universe is connected terrestrially. I developed the term called the "flat sphere" where I describe round earth as some sort of an illusion or a matrix. I think that somehow we are locked into this particular dimension of ours to perceive the reality as outer space where independent spherical bodies called planets are spread apart by great distances. Perhaps if we were to raise our vibrational frequency or travel to another dimension, the illusion of empty outer space and isolated spherical earth would vanish and we will see a clear picture of the universe as continual terrestrial infinity with no spaces in between worlds.
Amadeo F Giannini wrote a book called Worlds Beyond the Poles where he talks about physical connection of the universe. He claims that if one is to travel beyond the north or south pole, one would travel away from earth globe and encounter new uncharted land to what the ancients referred as celestial continents. Giannini gives the famous Admiral R Byrd expedition beyond the north pole as proof to such occurance. Perhaps this is true. It can be that the poles of the earth are the closed gates that are preventing us from going further. Perhaps one day these polar gates will be broken and we will be able to see the full extend of infinite earth/universe.
