Creating a mini self-sustaining star in a superstrong chamber is theoretically possible if the right materials are continuously fed into it, as a star primarily consists of hydrogen fusing into helium. However, achieving the necessary temperature of around 10 million kelvin for fusion poses significant challenges, particularly in terms of containment due to the extreme pressure and heat generated. While fusion reactors mimic this process, they require artificial compression and external energy, which detracts from the concept of a self-sustaining star. The delicate balance between explosive forces and gravitational pressure is crucial, necessitating advanced engineering and extensive calculations. Overall, while the idea is intriguing, practical implementation remains far from reality.
