abstract={In the projection gravitation theory, there exists a merging model of black hole formation. Particles that meet the merging condition can be combined together to form a black hole. The essence of a black hole is an empty hole. A black hole is not a single object, it is a composite particles system. From this model, the black hole entropy formula can be easily derived out. This merging condition is equivalent to a temperature condition. From this black hole model, we can easily derive out the Verlinde¡¯s entropy gravity proposal formula and the Unruh formula. It is also proved that the Verlinde¡¯s entropy gravity proposal formula and the Unruh formula are actually equivalent. The Verlinde¡¯s entropy gravity proposal theory is not universally correct, but only in special circumstances. The gravitational acceleration produced by an object has a maximum value. Projection gravitation theory has important research value.},
