Deep inside the Sun, the process of nuclear fusion occurs. Every second, the Sun emits some 3.846 × 1026 joules of energy, which are released via the conversion of mass into energy in the core. Einstein‘s E = mc2 is the root cause, nuclear fusion is the process, and the continuous emission of energy from the Sun is the result. This energy is the underlying process that powers practically every biologically interesting process occurring on Earth.
