review text: Summary: We propose a new definition of entropy for any mass \(m\), based on gravitation and through the concept of a gravitational cross section. It turns out to be proportional to mass, and therefore extensive, and to the age of the Universe. It is a Machian approach. It is also the number of gravity quanta the mass has emitted through its age. The entropy of the Universe is so determined and the cosmological entropy problem solved.
