What are the essential parts of everything? Humans have been pursuing the answer to this question for centuries. This exhibition presents the research that attempts to solve the mystery of subatomic particles by using a huge experimental device called the particle accelerator. Inside the particle accelerator, it tries to create unknown particles by accelerating protons and other particles that compose matter to a speed close to the speed of light, and then make them collide. The exhibit presents this great experiment through animation, photos, and interactive games.
