In this documentary episode, planetary engineers and leading scientists attempt to "build a universe" step-by-step from the top of an impossibly high tower.
Beginning 13.8 billion years ago with just hydrogen gas, scientists at an Oxford nuclear fusion lab use a robot named Mascot and a magnetic chamber to heat hydrogen to 100 million °C—generating fusion and manufacturing helium, carbon, and heavier elements just like stars do.
By diving into toxic, oxygen-free subterranean lakes in Italy's Frasassi caves and testing extreme low-pressure environments at NASA’s Building 9, researchers demonstrate why liquid water, proper atmospheric pressure, and planetary gravity are mandatory for life.
