Not all energy in stars is converted into matter. In stars, nuclear fusion processes convert hydrogen and other lighter elements into heavier elements, releasing energy in the process according to Einstein's mass-energy equivalence principle (E=mc²). During fusion, a small amount of mass is lost and converted into energy, which powers the star and produces light and heat.
In stars, especially during different phases of their life cycles, various types of energy—such as gravitational, thermal, and radiation energy—are present and continuously interacting. While mass is converted into energy during fusion, energy in the form of light and heat can escape into space rather than being converted back into matter.
Overall, while mass and energy are interchangeable in the universe, the processes in stars primarily convert some fraction of mass into energy rather than converting energy back into mass.
