UMass Amherst physicists believe such an explosion could occur within the next decade, potentially \u201crevolutionizing physics and rewriting the history of the universe.\u201d<\/strong><\/p>\n

Physicists have long thought that black holes end their lives in rare explosions that occur, at most, once every 100,000 years. New research in Physical Review Letters from University of Massachusetts Amherst<\/a> physicists points to a different outlook. The team estimates a probability greater than 90% that one such explosion could be observed within the next decade. If observers prepare in advance, today\u2019s space and ground observatories should be able to capture the event.<\/p>\n

Such a blast would strongly support the existence of a theorized but never directly observed kind of black hole called a \u201cprimordial black hole,\u201d which may have formed less than a second after the Big Bang 13.8 billion years ago.<\/p>\n

The explosion could also deliver a definitive inventory of all subatomic particles. That list would include known particles such as electrons, quarks, and Higgs bosons, proposed particles like dark matter candidates, and anything else that is currently unknown to science. With such a catalog, researchers could finally tackle one of humanity\u2019s oldest questions: where did everything come from?<\/p>\n

Understanding Black Holes<\/p>\n

We know that black holes exist, and we have a good understanding of their life cycle: an old, large star runs out of fuel, implodes in a massively powerful supernova, and leaves behind an area of spacetime with such intense gravity that nothing, not even light, can escape. These black holes are incredibly heavy and are essentially stable.<\/p>\n

But, as physicist Stephen Hawking pointed out in 1970<\/a>, another kind of black hole\u2014a primordial black hole (PBH), could be created not by the collapse of a star but from the universe\u2019s primordial conditions shortly after the Big Bang. PBHs, like the standard black holes, are so massively dense that almost nothing can escape them\u2014which is what makes them \u201cblack.\u201d However, despite their density, PBHs could be much lighter than the black holes we have so far observed. Furthermore, Hawking also showed that black holes have a temperature and could, in theory, slowly emit particles via what is now known as \u201cHawking radiation\u201d if they got hot enough.<\/p>\n

\u201cThe lighter a black hole is, the hotter it should be and the more particles it will emit. As PBHs evaporate, they become ever lighter, and so hotter, emitting even more radiation in a runaway process until explosion. It\u2019s that Hawking radiation that our telescopes can detect,\u201d says Andrea Thamm, co-author and assistant professor of physics at UMass Amherst.<\/p>\n

Yet, while we should be able to, no one has ever directly observed a PBH.<\/p>\n

\u201cWe know how to observe this Hawking radiation,\u201d says Joaquim Iguaz Juan, a postdoctoral researcher in physics at UMass Amherst. \u201cWe can see it with our current crop of telescopes, and because the only black holes that can explode today or in the near future are these PBHs, we know that if we see Hawking radiation, we are seeing an exploding PBH.\u201d<\/p>\n

A Paradigm Shift in Expectations<\/p>\n

Though physicists since Hawking\u2019s time have thought that the chances of seeing an exploding PBH are infinitesimally slight, Iguaz Juan notes that \u201cour job as physicists is to question the received assumptions, to ask better questions and come up with more precise hypotheses.\u201d<\/p>\n

The team\u2019s new hypothesis? Get ready now to see the explosion. \u201cWe believe that there is up to a 90% chance of witnessing an exploding PBH in the next 10 years,\u201d says Aidan Symons, one of the paper\u2019s co-authors and a graduate student in physics at UMass Amherst.<\/p>\n

In its work, the team explores a \u201cdark-QED toy model.\u201d This is essentially a copy of the usual electric force as we know it, but which includes a very heavy, hypothesized version of the electron, which the team calls a \u201cdark electron.\u201d<\/p>\n

The team then reconsidered long-held assumptions about the electrical charge of black holes. Standard black holes have no charge, and it was assumed that PBHs are likewise electrically neutral.<\/p>\n

\u201cWe make a different assumption,\u201d says Michael Baker, co-author and an assistant professor of physics at UMass Amherst. \u201cWe show that if a primordial black hole is formed with a small dark electric charge, then the toy model predicts that it should be temporarily stabilized before finally exploding.\u201d Taking all known experimental data into account, they find that we could then potentially observe a PBH explosion not once every 100,000 years as previously thought, but once every 10 years.<\/p>\n

\u201cWe\u2019re not claiming that it\u2019s absolutely going to happen this decade,\u201d says Baker, \u201cbut there could be a 90% chance that it does. Since we already have the technology to observe these explosions, we should be ready.\u201d<\/p>\n

Iguaz Juan adds, \u201cThis would be the first-ever direct observation of both Hawking radiation and a PBH. We would also get a definitive record of every particle that makes up everything in the universe. It would completely revolutionize physics and help us rewrite the history of the universe.\u201d<\/p>\n
