Researchers have put forward an unusual theory that may explain the existence of unusually cool red giants.
Astrophysicist Earl Bellinger has put forward an interesting theory that there may be black holes inside some stars, writes Futurism.
Bellinger and his team published their work in the Astrophysical Journal, where they took a closer look at the unusual idea. According to scientists, by studying vibrations on the surface of distant stars, it is possible to detect black holes trapped inside these unfortunate stars.

“I first thought it would be interesting to put a black hole inside a star and see what happens,” Bellinger said.
The generally accepted model of stellar evolution suggests that black holes arise from the collapse of massive stars. Not even light can escape their powerful gravity.
But in their research, Bellinger and his team explored a theory that suggests the universe is full of primordial tiny black holes, which could explain something called “dark matter” – a mysterious substance that accounts for approximately 85% of the matter in the universe.
The theory suggests that due to the abundance of these small and ancient black holes in the Universe, some of them may end up in stellar nurseries, and then in the stars themselves.
Trapped black holes would be extremely dense, having the mass of an asteroid but squeezed down to the size of a hydrogen atom. Such objects could drift closer to the core of stars.
What’s most surprising is that such black holes could even remain stable inside stars. According to Bellinger, it would take longer for a tiny black hole to devour a star than the existence of the Universe itself.
At the same time, larger black holes can devour a star within a few hundred million years, becoming an object called a “Hawking star.” Such stars rely not on the fusion of hydrogen atoms, but on the power of a black hole.
A new theory could help explain the discovery of hundreds of unusually cool red giants that are in a late phase of evolution. Researchers propose studying the vibrations on their surface to find out whether black holes are hidden in them.
Let us remind you that scientists have explained how black holes die. Astronomers say the death of black holes will be very different from their explosive birth.
