Five a long time ago, the famous astrophysicist Stephen Hawking theorized that Great explosion Perhaps he flooded the universe with small black holes. Now scientists consider that they’ve seen one exploded.
In February 2025, European cooperation of KM3NET – which consists of underwater detectors off the coast of France, Italy and Greece – announced the discovery incredibly powerful neutrino. This ghostly molecule had energy about 100 PEV – greater than 25 times more energetic than particles accelerated in a big Hadron bumper, the strongest in the world breaking the atom.
Physicists tried to provide you with a proof of such an brisk neutrino. But now a team of scientists who weren’t involved in the original detection, proposed a surprising hypothesis: Neutrino is the signature of the evaporate Black hole. The team described their proposal in paper This has been sent to the Arxiv database and has not yet been reviewed.
Hawking’s black holes
In the 70s, Hawking realized that black holes weren’t completely black. Instead, through complex interactions between the black hole Horizon Events And quantum space -time fields can emit a slow but everlasting stream of radiation, currently often called Hawking. It means Black holes evaporate And ultimately they disappear. In fact, when the black hole is getting smaller, it emits much more radiation until it principally explodes in a high-energy storm of particles and radiation-like neutrino noticed by KM3NET’s cooperation.

But all known black holes are very large – at least several times the mass of the sun and infrequently much larger. Dying as much as 10^100 years in order that even the smallest known black holes. If neutrino km3net is brought on by an exploding black hole, it must be much smaller – somewhere about 22,000 kilos (10,000 kilograms). It’s roughly as heavy as two fully adult African elephants, compressed in a black hole smaller than atom.
The only known potential way of producing such small black holes are the chaotic events of the early Big Bang, which could pour the cosmos “Primordial” black holes. The smallest primary black holes produced in an important explosion would explode a protracted time ago, while larger ones could last to today.
Unfortunately, a black hole weighing 22,000 kilos mustn’t survive from an important explosion to the present day. But the authors identified that there could be a further one Quantum mechanism – often called “memory load” – which allows black holes to repel the distribution. This would survive 22,000 kilos of a black hole for billions of years before it will definitely exploded, sending a high energy neutrino towards the Earth on this process.
Primary black holes can be a proof dark matter – an invisible substance that’s accountable for most matters in the universe – but to date the seek for them has develop into empty. This latest insight can be an intriguing clue. Scientists have found that if the original black holes of this range of mass are abundant enough to incorporate all dark matter, they need to explode a bit. They estimated that if this hypothesis is correct, KM3NET’s cooperation should see one other neutrino in the next few years.
If this detection occurs, perhaps we’ll simply must radically rethink the way we approach dark matter, high energy neutrinos, and even the physics of the early universe.
