In CERN I would do the things beyond anyone's imagination, discovering new particles, unrawelling the world's greatest mysteries and answering the biggest questions. Antimatter and tonnes of subatomic particles, for which electrons are as huge as a planet to us, were discovered there, theories proven.
They have the world's biggest particle accelerator LHC or the Large Hadron Collider, which can create particles like antimatter out of nothing. But, experimental physics and particle physics are very dangerous. The LHC can show us the birth of the Universe, create a new one out of nothing in the shape of two particles, matter and antimatter. Imagine what would happen if something went wrong!
The leading scientist there is Stephen Hawking, who has a new unifying theory of everything, the String theory, which unites Einstein's theory of relativity and quantum theory and which is based on twenty-six dimensions!
It is my dream job because there I would be able to build the future and answer the questions about the universe.
