No, the sun is not hollow. The sun is a massive ball of gas, primarily made up of hydrogen and helium, with a small solid core at its center. The intense pressure and temperature at the core of the sun cause nuclear fusion reactions to occur, producing the sun's energy and heat. The sun's density increases towards its core, making it a solid and dense object rather than hollow. **
