The universe contains cosmic plasma of baryonic matter, in addition to dark matter and dark energy. The so-called nonthermal components of the plasma, that is, shock waves, magnetic fields, cosmic rays and turbulence, are expected to play significant roles in the formation and observation of the large-scale structure of the universe. Yet their nature and origin are not fully understood. In the lab, the cosmic plasma as well as dark matter and dark energy are explored. Along with numerical simulations for the formation of the cosmic web, theoretical arguments based on plasma physical models for collisionless shock wave formation, cosmic ray acceleration, astrophysical turbulence, and magnetic field generation are employed.
