Life cycle of a star Every star has a life cycle just like a human or a frog except stars do it on a much larger scale.

When a stars life ends it may explode or implode to create a black hole. The reason stars even start life and end life is because of nuclear fusion.

Knowing Macau with Butler’s Life Cycle Model The following literature is suggesting that how a tourist destination can be analyzed with the help of Butler’s Tourism Life Cycle Model. Butler (1980) introduced the concept of the model which clarifies and extends earlier work by‚ for example‚ Cristaller (1963)‚ Noronha (1976) and Stansfield (1978). In doing so‚ Butler clearly links the development cycle of tourism destinations to that of products in the product life cycle model. This is one the best
