Observations and models hint that most of the matter of the universe is invisible . It does n’t interact with brightness level , and only makes its bearing known with gravity . For this reason , it is calleddark subject . There is another celestial characteristic that also does n’t emit swooning : black holes . Researchers have long hint that they are one and the same .
Now , a team of physicists from the University of California Berkeley has decree this out , claiming that black holes can not be the main part of blue matter . In a paper publish inPhysical Review Letters , they submit that black holes that formed during the Big Bang can at most account for 40 per centum of drab matter . An expansion on their analysis , which is yet to be put out , puts the phone number as blue as 23 percent .
The squad analyse 740 of the brightest distant supernovae to make this estimate ( in the study currently in the works , the number is 1,048 ) . The theory is if black holes – which are usually found at the center of beetleweed – were the cause of glum matter , they would be scattered around galaxies and not just found in the centre . Being such impenetrable objects , they bend space - time and they can playact as agravitational lens , magnifying the light of background physical object .
For morose matter to be black kettle of fish you would need a lot of them , and so the light of at least some of these supernovae should be affected . However , no changes in the luminosity of their igniter were observed , indicate that dark muddle can not be the main component of dark matter .
However , this does n’t necessarily absolved things up , it may have actually made things regretful . The strongest hypotheses had drab matter made of a undivided constituent , whether disastrous hole or microscopical particles . Having dark matter made of several different things might make it even more complicated to explain how all the dissimilar portion signifier .
“ I can suppose it being two type of bleak holes , very weighty and very light one , or opprobrious hole and Modern subatomic particle , " leave writer Miguel Zumalacárregui , a Marie Curie Global Fellow at the Berkeley Center for Cosmological Physics , hypothecate in astatement .
" But in that case one of the constituent is orders of magnitude heavier than the other , and they require to be produced in comparable abundance . We would be perish from something astrophysical to something that is truly microscopic , perhaps even the clear thing in the universe , and that would be very difficult to explicate . "
The mystery of what sour thing is still remains , but at least we make love that we can probably prevail out ignominious holes as the principal cause behind it .
