Is Dark Matter Made Of Black Holes?

Scientists may have come up with the explanation linking Primordial Black Holes and Dark Matter

An alternative view that dark matter is made of black holes formed during the first second of  our universe’s existence, known as primordial black holes is now being backed up by scientists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, as they say it would align with  our knowledge of cosmic infrared and X-ray background glows and may explain the unexpectedly high masses of merging black holes detected last year.

“Future LIGO observing runs will tell us much more about the universe’s population of black  holes, and it won’t be long before we’ll know if the scenario I outline is either supported or  ruled out” said NASA spokesman.
