Scientists are finally close to seeing what dark matter is. It is what most of the universe is. There is a device called the Large Hadron Collider. This is the world’s largest and most powerful particle collider. It has a 27-kilometer ring of super magnets inside. From both sides, it produces a particle beam that passes over each other at the speed of light. A particle beam is made up of subatomic particles that are smaller than atoms. The reason for this device is to test theories and discover new particles. People say that soon maybe it can uncover the truth about dark matter.
