Big bang cycles

Proponents of plasma cosmology are a funny group. They complain the big bang theory is bad science. They claim it requires too many ad hoc assumptions even though it has made numerous successful predictions about the universe, making it a good scientific theory. They seek to replace it with a model that a. makes many ad hoc assumptions of it's own and b. has not made successful testible predictions, leaving it as a mere model while the big bang is a theory. It's even hard to get proponents of plasma cosmology to reveal any prediction the model makes at all, bringing us to the question of whether or not the model is even scientific.
