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. 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. People say that soon maybe it can uncover the truth about dark matter.
