Cosmologists Dejan Stojkovic and De-Chang Dai propose that tiny black holes, known as Primordial Black Holes (BNPs), may be present not only in deep space, but also right here on Earth.
According to their research, these miniature black holes can occasionally pass through random objects – including those inside our home – without leaving a trace.
Unlike traditional black holes, which form from the collapse of massive stars, BNPs are thought to have emerged shortly after the Big Bang. During this period, the Universe was much denser than it is today, creating conditions for the formation of these small but incredibly dense black holes.
BNPs have remained largely theoretical, but some scientists believe that can explain dark matterthe mysterious substance that makes up much of the Universe but cannot be directly observed.
Stojkovic and Dai’s hypothesis goes a little further. According to , researchers suggest that these black holes, due to their small size and immense density, may be able to open microscopic tunnels through solid objects. These holes would be almost impossible to detect, as black holes would move too quickly and release minimal energy as they passed through matter.
Researchers have explored the idea of BNPs interacting with celestial bodies, such as planets, moons or asteroids. If a BNP passed through a body with a liquid core, it could become trapped inside, gradually consuming the liquid material over time.
This process could theoretically drain the core of a planet, leaving it hollow. The BNP would only detach if an external impact, such as a large collision, provided enough force to release it.
Naturally, the idea of black holes passing through objects in our homes may raise some concerns. After all, if a BNP can pass through solid rock, what would happen if it found a human body?
Stojkovic and Dai assure us that the risk is negligible. For one thing, BNPs are incredibly small, being able to open holes just 0.1 microns wide. Their speed prevents them from transferring too much kinetic energy, which means they pass through objects without causing significant damage. Human tissue, being soft and flexible, would likely allow a BNP to pass through without tearing or fragmenting the cells.
The results of the study were recently published in the journal Physics of the Dark Universe. If proven, BNPs could reshape our understanding of dark matter, the early universe, and even the long-term evolution of planets.
