cosmic bubble, symmetry continued to break and the wall moved outward, making the bubble grow. Just inside this wall the Higgs fields were releasing their energy as they decayed. So the bubble was gradually filled with energy. This energy filled the Cosmos with fields, particles and radiation. This is called the Big Bang. Note that each cosmos would have had its own bang.
Particles and antiparticles would have been created together. Antiparticles are identical to particles except they have the opposite electric charge. More matter was produced than antimatter, probably due to the strange decay of some heavy particles.
The following light weight particles (leptons) would have been created:
The following heavy particles (hadrons) would have been created:
Some other strange objects might also have been produced, including
