📖 Read the story

Everything around us is matter. But there is something else called antimatter. It is like a twin of matter, but it is opposite. When they touch, they disappear in a bright light. This makes it very hard to study. Scientists must keep antimatter away from everything. In March, scientists at CERN did something cool. They moved antimatter in a truck! This was the first time ever. They used strong magnets to keep it in the middle of a box. The magnets stopped it from hitting the walls. If it hits the walls, it is gone! Antimatter is very rare. There is a lot of matter in space, but only a little antimatter. No one knows why. This is a big mystery. Now, scientists can move it to different labs. This helps them learn more about our universe. It is an exciting step for science!
