Dark Matter

Invisible dark matter is estimated to make up as much as 95% of the universe, but we can only see it by the gravitational effects on other, visible objects. Researchers at NYU, including graduate student Cara Giovanetti have developed a better way to model the cosmological signatures of dark matter. We’ll here from her as well as astrophysicist Dr. Joseph Pesche as we ask does dark matter exist, and if so, what is it made of?
