By recreating Big Bang conditions, scientists at CERN trie to answer following questions:
- Why is there no-more antimatter left, although both, matter and antimatter were resulting from the Big Bang in equal parts and thus, should've annihilate themselves?
- Why do particles have mass? What is mass? Is the origin of mass the Higgs-boson?
- Does dark matter exist? What is dark matter?
- Do extra dimensions exist?
