Could it be the earth is flat and that the stars above us are in liquid hydrogen (due to upward pressure of this least dens material) and that's why they are shimmering like lights in water and that the lights are created by (sound) frequencies like music has a verse and this is our uniVERSE? Just thinking out loud... Why are the planes called plane and are boats using circumnavigation? Is our PLANEt a PLANEterra, flat earth?
