What is dark matter in space? How do we know there is dark matter? What is dark matter made of?
Answers
Answer:
Dark matter is stuff in space that has gravity, but it is unlike anything scientists have ever seen before. Together, dark matter and dark energy make up 95% of the universe. ... It's made of galaxies, stars, planets, black holes, comets, asteroids, and all the other cool space stuff!”
Scientists study dark matter by looking at the effects it has on visible objects. Scientists believe that dark matter may account for the unexplained motions of stars within galaxies. ... Scientists believe that dark matter in the cluster accounts for the unexplained mass.
Most scientists think that dark matter is composed of non-baryonic matter. The lead candidate, WIMPS (weakly interacting massive particles), have ten to a hundred times the mass of a proton, but their weak interactions with "normal" matter make them difficult to detect.
