Human civilization is a global, highly complex system shaped by the biological species Homo sapiens, which has evolved from local bands of hunter-gatherers into a deeply interconnected, information-driven global society of over 8.3 billion people. Originating in Africa around 300,000 years ago, humanity made its first fundamental leap during the Neolithic Revolution roughly 10,000 to 12,000 years ago by transitioning from nomadic foraging to settled agriculture; this shift generated food surplus

Nuclear fusion is the process where light atomic nuclei combine to form heavier ones, releasing a gargantuan amount of energy. This very reaction is what powers the Sun and all other stars. Deep inside a star, extreme gravity and temperatures of millions of degrees force hydrogen nuclei to overcome their natural repulsion and fuse into helium. The mass of the resulting helium is slightly less than the combined mass of the original particles, and this lost mass is converted into pure radiative en
