Results from the LHC can expand our knowledge of the early stages of the universe. The connection between the world of particle physics and the structure of our universe is probably one of the most profound results of modern science, which captivates the imagination of anyone who is confronted with its wonders. This chapter describes this connection, explaining how the process of inflation could be at the origin of the cosmological properties we observe today. The empirical evidence in favour of dark matter is by now overwhelming. This still unknown form of matter could be made of some new kind of particle that can be produced at the LHC. This chapter presents the case of dark matter at the LHC and the ways in which the new form of matter could be discovered. It explains what dark energy is and its potential impact on the naturalness problem.
