👉 Semistarvation is a concept in physics that describes a situation where an object, such as a star or planet, experiences a state of complete absence of all its internal energy and mass. In this condition, the object's mass would be equal to its entropy, which is defined as the total energy contained within the system. When an object is semistarvation, it has no apparent process for generating new matter, which means that it will eventually run out of energy. The term "semistarvation
