Abstract In this work, we explore some cosmological implications of the model proposed by M. Visser in 1998. In his approach, Visser intends to take into account mass for the graviton by means of an additional bimetric tensor in the Einsteinʼs field equations. Our study has shown that a consistent cosmological model arises from the Visserʼs approach. The most interesting feature is that an accelerated expansion phase naturally emerges from the cosmological model, and we do not need to postulate… CONTINUE READING
