A new study theorizes that primordial black holes formed after the Big Bang (the far left panel) constitute all dark matter in the universe. At early epochs they cluster and seed the formation of early galaxies and then eventually grow by feeding off gas and merging with other black holes to create the supermassive black holes seen at the center of galaxies like our own Milky Way today.

Primordial black holes created in the first instants after the Big Bang — tiny ones smaller than the head of a pin and supermassive ones covering billions of miles — may account for all of the dark matter in the universe.
That’s the implication of a new model of the early universe created by astrophysicists at Yale, the University of Miami, and the European Space Agency (ESA). If proven true with data from the soon-to-launch James Webb Space Telescope, the discovery would transform scientists’ understanding of the origins and nature of both dark matter and black holes.
Dark matter — which has never been directly observed — is thought to constitute the majority of matter in the universe and act as the unseen scaffolding upon which galaxies form and develop. Physicists have spent years testing a variety of dark matter candidates, including hypothetical particles such as sterile neutrinos, Weakly Interacting Massive Particles (WIMPS), and axions.
Black holes, on the other hand, have been observed. A black hole is a point in space where matter is so tightly compacted it creates intense gravity. Not even light can resist its pull. Black holes are found at the centers of most galaxies.
The new study, accepted for publication in The Astrophysical Journal, harkens back to a theory first proposed in the 1970s by physicists Stephen Hawking and Bernard Carr. At the time, Hawking and Carr argued that in the first fraction of a second after the Big Bang, tiny fluctuations in the density of the universe may have created an undulating landscape with “lumpy” regions that had extra mass. These lumpy areas would collapse into black holes.
Although the theory did not gain traction within the wider scientific community — the new study suggests that, if modified slightly, it could have explanatory power after all.
If most of the primordial black holes were “born” at a size roughly 1.4 times the mass of Earth’s sun, they could potentially account for all dark matter, said Yale professor of astronomy and physics Priyamvada Natarajan, the paper’s theorist.
Natarajan and her colleagues say their new model shows that the first stars and galaxies would have formed around black holes in the early universe. Also, she said, primordial black holes would have had the ability to grow into supermassive black holes by feasting on gas and stars in their vicinity, or by merging with other black holes.
“ Primordial black holes, if they do exist, could well be the seeds from which all supermassive black holes form, including the one at the center of the Milky Way,” Natarajan said.
“ What I find personally super exciting about this idea is how it elegantly unifies the two really challenging problems that I work on — that of probing the nature of dark matter and the formation and growth of black holes — and resolves them in one fell swoop,” she added.
The James Webb telescope’s mission will be to find the first galaxies that formed in the early universe and see stars forming planetary systems.
The new study’s first author is Nico Cappelluti, a former Yale Center for Astronomy & Astrophysics Prize postdoctoral fellow who is now an assistant professor of physics at the University of Miami. Günther Hasinger, ESA’s director of science, is the study’s second author.
“ Our study shows that without introducing new particles or new physics, we can solve mysteries of modern cosmology from the nature of dark matter itself to the origin of super-massive black holes,” Cappelluti said.
Primordial black holes also may resolve another cosmological puzzle: the excess of infra-red radiation, synced with X-ray radiation, that has been detected from distant, dim sources scattered around the universe. Natarajan and her colleagues said growing, primordial black holes would present “exactly” the same radiation signature.
Best of all, the existence of primordial black holes can be proven — or disproven — in the near future, courtesy of the James Webb Space Telescope and ESA’s Laser Interferometer Space Antenna (LISA) mission announced for the 2030s.
If dark matter is comprised of primordial black holes, more stars and galaxies would have formed around them in the early universe — precisely the epoch that the James Webb telescope will be able to see. LISA, meanwhile, will be able to pick up gravitational wave signals from early mergers of primordial black holes.
“ If the first stars and galaxies already formed in the so-called ‘dark ages,’ Webb should be able to see evidence of them,” Hasinger said.
Natarajan added, “It was irresistible to explore this idea deeply, knowing it had the potential to be validated fairly soon.”

Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or "stuff," in an object. Another kind of black hole is called "stellar." Its mass can be up to 20 times more than the mass of the sun.
A black hole is a region of spacetime where gravity is so strong that nothing - no particles or even electromagnetic radiation such as light - can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole . The boundary of no escape is called the event horizon.
Nikolai Shaposhnikov and Lev Titarchuk, who work at NASA's Goddard Space Flight Center in Greenbelt, Md., have identified the smallest known black hole in the universe. This black hole would weigh the same as 3.8 of our Suns if it could be put on a giant scale. The Sun is a huge object, and could contain more than a million Earths. So an object weighing the same as 3.8 Suns might sound like a lot. But it's a pipsqueak when compared to all other known black holes .

TON 618 (short for Tonantzintla 618) is a hyperluminous, broad-absorption-line, radio-loud quasar and Lyman-alpha blob located near the border of the constellations Canes Venatici and Coma Berenices, with the projected comoving distance of approximately 18.2 billion light-years from Earth. It possesses one of the most massive black holes ever found, at 66 billion M ☉.
