As Harvard-Smithsonian Center for Astrophysics in Massachusetts professor Ralph Kraft, who wasn't involved in the studies, told New Scientist,

"Everybody sort of knows that it has to be there, but this is the first time that somebody - two different groups, no less - has come up with a definitive detection."

He added,

"This goes a long way toward showing that many of our ideas of how galaxies form and how structures form over the history of the universe are pretty much correct."

Beyond giving scientists the ability to throw around an "I told you so" or two, the discovery of this missing matter also has the potential to improve our current maps of the universe and inform future research.


The more we learn about this world in which we live, the more we increase our ability to maneuver within it, perhaps one day reaching the very same distant galaxies studied by these groups of researchers.
