Abstract: | According to recent investigations of states of quantum fields, we
postulate that there exist negative energy photons in the universe.
With this assumption, we find a solution of Einstein's equation
without introducing the cosmological constant. A new and sizable
type Ia supernovae sample is employed to perform a fit with our
model and the conventional model. Both models can well account for
the current type Ia supernovae observation and they are not
distinguishable. With the new model, the cause of the accelerated
expansion of the universe and the mechanism of the negative pressure
existing in outer space can be explained in ordinary physical terms. |
