Neil deGrasse Tyson offers a comprehensive analysis of what dark matter and dark energy could be. With his usual wits & style he explains all known hypotheses for what the mysterious substance called dark matter might be. Neil deGrasse Tyson, the most well known astrophysicist of our era if not of all time also asks a mind boggling question about the origin of dark matter. He entails how dark matter or more fittingly dark gravity could originate from other universes in the multiverse.

Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe. to precisely assess the age of the universe to be 13.77 billion years old and to determine that atoms make up only 4.6 percent of the universe, with the remainder being dark matter and dark energy.

Neil deGrasse Tyson tells the story of the WMAP and how it enriched our understanding of the universe. This mysterious substance called dark matter, makes up the bulk of a galaxy's mass and forms the foundation of our Universe's large-scale structure. Because dark matter does not emit, absorb, or reflect light, its presence is only known through its gravitational pull on visible matter in space.

The universe is far from being fully understood. There are many different theories as to what dark matter and dark energy actually are, but scientists have been searching for these elusive entities for decades. Recently, new methods of detecting these entities have been developed, which could lead to a significant breakthrough in our understanding of the universe.
