Abstract We discuss the possibility that the existence of dark energy may be due to the presence of a spin zero field Ф(x), either elementary or composite. In the presence of other matter field, the transformation Ф(x) → Ф(x) + constant can generate a negative pressure, like the cosmological constant. In this picture, our universe can be thought as a very large bag, similar to the much smaller MIT bag model for a single nucleon.
