The rest remains a mystery and is called dark matter. This is one of the most fascinating theories in physics and answers many of the questions scientists ask themselves when studying the cosmos.Scientists around the world, such as Vera Rubin, are searching every day for new ways to find it, and thanks to teamwork and technological advances, they are getting closer.—DRA.
