In 1969 when Armstrong first landed on the moon, it was the biggest event of our time. It left everyone watching in awe. The moon lander, a machine that looked like a miracle in technology at the time, is nowadays the technical equivalent of something so small and insignificant as a Furby toy. Technological progress is so accelerated that even the humans that are behind the technology are surprised by its power and potential. We ask the question "how far can we really go?" The conclusions we reach may surprise and even scare us. National Geographic goes deep into scientific research to find answers for these questions.
