Why This Stuff Costs $2700 Trillion Per Gram - Antimatter at CERN

Anti matter and matter create light? maybe our suns have anti matter cores, and because of void space the energy released mostly collapses on its own gravity, creating the molten sure face of the sun through continues reaction. If this is true than that could mean, All the anti matter collapsed into stars. so maybe its not that rare, because we have just about as many stars, as star dust matter in the universe.
Am i wrong? just a random thought, if this does that, than maybe that is this! :D
I mean if they both have to exist in the same amount, matter and anti matter, then perhaps the two are needed and intertwined in order for our existence to even be, in the fact that its all just becomes Stardust after all
