Black holes are one of the most terrifying phenomena in our universe. No one and nothing could escape its gravity, not even light itself. However, scientists are currently studying the possibility of mini black holes spread throughout the galaxy, and if one passes by Earth and even your home, we just can’t detect them yet.
What Are Mini Black Holes?
Mini black holes, or scientifically known as primordial black holes, are theorized to be as small as an atom that may have formed shortly after the Big Bang. Most of the time, when we think of blackholes, we imagine the gigantic cosmic entity that eats up planets and stars, so how could one exist in my own home, right?
Well, first of all, they are only theoretical; no scientific evidence has been confirmed yet, but the research is ongoing. Secondly, if they truly exist, they would be so small that we would not be able to notice them as they pass by, just like we can’t see the atoms that make up everyday objects, but we know they do exist.

Could They Be Around Us?
Some researchers are convinced that tiny black holes are everywhere around us and exist in today’s time and space. They are possibly passing through Earth and even into someone’s home. If you are imagining black holes that eat up planets, this one is a little different; instead, due to their size and speed, they will pass through solid objects.
Scientists are looking into microscopic tunnels that are theorized to be left behind whenever mini blackholes pass by. They are scanning older rocks and structures, looking for the existence of these tiny tunnels. However, those are very hard to detect, and no evidence has been seen yet.
Are They Dangerous?

No, the short answer is they are not dangerous if these theoretical tiny black holes are real. They are atomic in size and would instead pass through matter, whether it is solid, liquid, or gas. That includes going through our bodies, without causing any harm.
These miniature black holes are also thought to evaporate through Hawking radiation. This is a process that even the biggest black hole undergoes, whether over time, they lose mass and energy, until they completely evaporate. In the case of the larger black holes, it might take trillions of years, but the tiny ones could evaporate completely in years.

Why Should We Care?
There are several important insights we could gain if miniature black holes are proven to exist. First is with dark matter, which is thought to make up 27% of our universe. They are mysterious substances that influence gravitational fields but do not interact with light. The primordial or mini black holes could help explain this theory if proven.
Another is that they are thought to be the seed or the beginnings of how the large black holes came to be, which are found in the center of most galaxies. They are also thought to influence the formation of early planets, where tiny black holes serve as the anchor for gases and galaxy dust to accumulate in a specific point. That could explain how planets, stars, and galaxies began to form after the Big Bang.
Author's Final Thoughts
While the idea of black holes hiding and passing through our homes and bodies sounds like something from a science fiction book or movie, it could be a real possibility that could help explain the universe’s countless mysteries. Also, if we began to understand how black holes form and function with the help of their smaller counterparts, then maybe the bigger ones would not be as terrifying afterward.
