It is a well-known apocalyptic fiction story. A black hole is created when the sun, our valuable source of heat and light, falls. Or maybe it gets sucked up by a rogue black hole that happens to come along. The Final Hour Is Near! We would only have roughly eight minutes left before, in the words of the kids, “it gets real” if a stellar-mass black hole ate our sun. Imagine instead that a tiny primordial black hole was ingested by the sun. That’s absolutely worth a paper on the arXiv preprint service. After that, things get interesting.
The idea that the Sun could turn into a black hole is a well-known astronomical speculation concept that is evocative of dystopian literature.
What if a tiny primordial black hole made a trip inside the Sun?
An interesting paper on the arXiv explores the possibilities of this intriguing scenario.
It is thought that primordial black holes are fictitious objects that emerged in the early stages of the universe. Primordial black holes, in contrast to known stellar-mass or supermassive its, are thought to be tiny, with masses similar to asteroids and diameters smaller than a baseball. These theoretical ideas are relevant to models that attempt to explain a distant Planet X.
The study highlights how little of an initial influence a captured primordial hole would have on a star similar to the Sun. Even a hole the mass of an asteroid would have very little effect because of its tiny mass in relation to the Sun. It might, however, have an impact on the star’s evolution over time. A star’s black hole progressively expands by consuming material from the star’s core. The research investigates situations in which the hole either completely devours the star or modifies its life cycle.
The result depends on how big the original hole was. The study indicates that eating a star within half a billion years is possible for those at the greatest mass range, which is around a billionth of a solar mass.
The dynamics grow more complex for smaller primordial black holes, less than a trillionth of a solar mass. These holes might cause turbulence in the stellar core, which would have unique effects, even if they would consume materials inside the star more slowly. The star might grow into a “red straggler,” which would look redder and colder than other red giant stars. The authors suggest that star seismology may be able to identify the existence of a primordial black hole.
It is important to remember that the most recent research on helioseismology suggests that there is either no hole in our Sun or if one exists, it is very tiny. As a result, there won’t be a solar Armageddon very soon. Still, the findings suggest that Hawking stars might be hidden somewhere in the cosmic fabric and just waiting to be found.

According to the study, it mostly depends on how big the original hole was. It could theoretically devour a star in less than half a billion years for those at the highest mass range not precluded by measurements, which is around a billionth of a solar mass. There should be solar mass black holes in the universe if this has occurred, since they are too small to have generated from supernovae like conventional stellar-sized black holes.
