ALICE experiment

The ALICE experiment at CERN studies the conditions of the universe moments after the Big Bang. It does this by smashing heavy ions, like lead nuclei, at very high energies to recreate extremely hot and dense environments. By analyzing the particles emitted from these collisions, ALICE helps scientists understand how quarks and gluons—the fundamental building blocks of matter—behaved in the early universe, leading to the formation of protons and neutrons. Overall, ALICE provides valuable insights into the origins of matter and the fundamental forces that shaped our cosmos.
