Scientists Created the Largest 3-D Map of the Distant Universe

Scientists from the Sloan Digital Sky Survey created the largest 3-D map of the distant universe using the light of the brightest objects in the cosmos.To create this map scientists relied on 14,000 quasars. The map shows a time 11 billion years ago, when the first galaxies were just beginning to come together under the force of gravity to form the first large clusters.With the help this map scientists hope that they can study how the expansion of the universe has changed during its history, and they can learn more about mysterious dark energy, which, how scientists think, had a great impact to the expansion of the universe.
