After Big Bang: Are There Different Universe Building Blocks?

[Jobrag]

After the Big Bang the matter of the universe started to condense and we ended up with matter built up of neutrons, protons and electrons, are there any models that starting from the same BB give a universe made up from totally different building blocks?

Not without completely different physics. It is hard enough to evaluate the physics of our universe - there are calculations how the world would look like if the fundamental laws are changed a bit, but I don't know of any detailed concept for a completely different set of physical laws.
