A new study by the University at Buffalo has propose that evidence of primordial black holes (PBHs), form in the early universe, can be find in both cosmic and terrestrial objects. As per researchers, these small black holes may have left behind unique signatures, such as hollow planetoids in space or microscopic tunnels in materials on Earth.
These findings, as per reports, suggest new avenues for exploring the elusive nature of PBHs, which remain unobserved despite their potential link to dark matter.
As per the study publish in Physics of the Dark Universe, PBHs may form in regions of high density during the universe’s expansion after the Big Bang.
Unlike stellar black holes, PBHs are believe to be much smaller, with the mass of a mountain compressed into an atomic-sized space.
The researchers, led by Dr Dejan Stojkovic, a professor of physics at the University at Buffalo, suggest in their statements that PBHs trap within celestial objects like asteroids or moons can consume their cores, leaving hollow shells.
Dr Dejan Stojkovic said that hollow structures form in this manner can be no larger than one-tenth of Earth’s radius.
Larger hollow objects would collapse due to their own tension.
Detecting such low-density celestial bodies through orbital studies can help identify these black hole remnants.
The study also proposes that PBHs passing through solid materials can create minute tunnels, visible under a microscope.
Dr De-Chang Dai, co-author and physicist at National Dong Hwa University, highlight that old materials, such as ancient rocks or historic building components, could be examine for such evidence.
As the probability of a PBH interacting with earthly objects is low, estimate at one in a million over a billion years, Dr Dejan Stojkovic emphasise the minimal cost of such investigations compare to the potential scientific rewards.
