Tiny Black Holes Rip Atoms Apart ⚡ экспресс
Primordial black holes (PBHs) in the asteroid-mass range (10^17–10^23 g) are dark matter candidates, but their detection is hampered by weak Hawking radiation. This work explores the tidal gravitational effects of PBHs, which can ionize neutral hydrogen or destroy nuclei. It is shown that today, gravitational ionization is masked by Hawking radiation, but during the recombination epoch (z≈1090) for PBHs with masses 5×10^21–10^23 g, gravitational heating dominated. Tidal forces also overcome the strong interaction: dissociating deuterons (critical for primordial nucleosynthesis) and inducing fission of heavy nuclei. For PBHs of 10^14–10^16 g, gravitational deuteron breakup surpasses photodisruption from Hawking radiation. The phenomenon of gravitationally induced nuclear fission via tidal deformation is unveiled.
Tiny black holes, the size of an atom but heavier than an asteroid, were born right after the Big Bang. Now, they are probably the dark matter — the invisible mass that keeps galaxies from flying apart. You can't catch them directly: they emit almost nothing.
But their gravity tears hydrogen like soft taffy — one side of the atom gets pulled harder than the other, and it bursts. Flashes from these ruptures are sought in the ancient radio waves left over from the era 380,000 years after the Big Bang.
The most unexpected surprise: these black holes can even shatter deuterium nuclei. That changed the chemical composition of the early Universe — and perhaps exactly such a trace will point to the nature of dark matter. Such a search method might have surprised George Gamow and Ralph Alpher, who laid the foundations of cosmic chemistry.
🎯 A black hole with the mass of an asteroid but smaller than an atom tears apart a deuterium nucleus — a hydrogen isotope — with tidal force, and this changed the chemical makeup of the early Universe.
