Original sentence: Because Plasma cosmology depends on physics that is well known, it cannot be modified to fit any basic random theory to fit unknown observations.Because the other models involves physics that are poorly understand, they are adjusted based on whatever can fit the current observation by invoking exotic physics, such as a new particle or an unknown field.From an observational view, the interface between matter and anti-matter has not been visible using gamma telescopes which were not available when Alfven first proposed his model.Increase in technology and science will expand the area detectable.One could rescue this Plasma cosmology by proposing as Alfven does that the bubble of matter we are in is larger than the currently available ability to observe the universe
Edited sentence: Because the Alfven model depends on physics that is well known, it cannot be modified to fit any basic random theory to fit unknown observations.Because the other models involves physics that are poorly understand, they are adjust based on whatever can fit the current observation by invoking exotic physics, such as a new particle or an unknown field.From an observational view, the interface between matter and anti-matter should easily be visible using gamma telescopes which were not available when Alfven first proposed his model.One could rescue this model by proposing as Alfven does that the bubble of matter we are in is larger than the observable universe.This then presents the problem of how to test the theory at all
