This slow process of diffusion can take tens of thousands of years for a single photon to reach the surface. The missing 4 million tons of mass is not destroyed but is converted directly into energy, as described by the principle of mass-energy equivalence.
Mass Loss in Nuclear Fusion: How the Sun Converts Matter into Energy
This continuous loss of mass results in a very gradual decrease in the Sun's gravitational pull. Intermediate Steps and Helium Formation Following the creation of deuterium, the reaction pathway quickly escalates in complexity.
This transformation is not a simple chemical burn like combustion on Earth; rather, it is a fundamental change in the structure of atomic nuclei, converting matter directly into energy according to Einstein's famous equation, E=mc². High-energy gamma rays produced in the core are absorbed and re-emitted countless times by particles in the dense plasma, gradually losing energy and shifting to longer wavelengths.
Mass Loss in Solar Nuclear Fusion: Hydrogen to Helium Conversion
The nuclear reaction occurring at the heart of our solar system is the fusion of hydrogen nuclei into helium, a process that releases an immense amount of energy in the form of light and heat. This initial step is the rate-limiting phase of the process, as the conversion of a proton to a neutron is inherently difficult due to the forces involved.
