Most of the universe is unseen, like dark matter and dark energy, making up 95%. Scientists can't see them but use special tools to find tiny particles that might show they exist. The International Space Station has a super-sensitive tool since 2011. It checked 41 billion cosmic rays to find particles called "neutralinos," linked to dark matter. These particles don't react with anything, even light. To be sure they exist, scientists need them to crash into each other, making other particles the tool can find.

Scientists on the space station saw changes in the number of electrons and their opposites, positrons. This suggests dark matter might be real. More proof might come from the Large Hadron Collider, a big machine in the ground, soon to start again after an upgrade.
