According to an ESA statement, "The map provides the best evidence yet that normal matter, largely in the form of galaxies, accumulates along the densest concentrations of dark matter." The most distant observations reflect the situation halfway back to the beginning of the universe, and the map shows how dark matter becomes increasingly clumpy over time as gravity draws it together. "It’s reassuring how well our map confirms the standard theories for structure formation," said CalTech's Richard Massey, senior author of the report describing the project. "Now that we have begun to map out where dark matter is, the next challenge is to determine what it is, and specifically its relationship to normal matter."{moscomment}
