Researchers at the Max Planck Institute for Astrophysics were inspired by a song to find out how true Stephen Hawking's theory is.

Even scientists are sometimes inspired by the works of science fiction writers, but it is very rare for a researcher to be inspired by the work of a musical group. And that's exactly what happened to Max Planck Institute for Astrophysics astrophysicist Earl Bellinger, who was Soundgarden The sun's black hole Inspired by his song.

According to the current state of science, black holes can be created from a star if it is at least 25 times larger than the Sun. Black holes are created during the collapse of a supernova explosion, which then begins absorbing surrounding material.

Bellinger, along with eight of his colleagues, began wondering whether black holes could exist inside the star. More specifically: within average stars like the Sun. Surprisingly, they came up with the answer that yes, they could exist, as it turns out Astrophysical Journal From the scientific journal.

But let's stop for a moment. Black holes are known to have such strong gravity that not even light can escape, so Bellinger and his team's findings seem illogical, he writes. IFLScience.

But there are also quasars, star-like radio sources that are thought to contain at their core a giant source of energy, most certainly a supermassive black hole. The theory that there is an ancient black hole at the center of the sun was actually proposed by Stephen Hawking, but Bellinger and his team have also begun investigating how stars would evolve if this statement is true.

The study is based on the idea that in the first second after the Big Bang, many small black holes with masses similar to or less than the Moon were formed. In such a case, the smallest black holes would evaporate, but larger, asteroid-sized black holes would still exist and drift through the universe.

These ancient black holes may be enough to explain at least some of the dark matter in the universe. Most holes are likely to be around stars, making them difficult to observe, but if they get sucked into a cloud of gas where star formation occurs, a black hole could easily find itself in the core.

During the investigation, they concluded that the impact of black holes with a mass smaller than the asteroid Psyche could not be observed. Although it would consume the surrounding areas, the affected area would essentially be so small that an outside observer would not be able to tell the difference.

However, if the black hole's mass is larger, it will cause the star to slowly fade away and stop the fusion reaction. For this reason, stars of similar age and mass would be brighter if they did not have a black hole.

In the case of the Sun, calculations indicate that if it had a black hole with a mass three times that of Mars, its brightness would halve within 100 million years. But then it will get brighter, because instead of nuclear fusion, the accretion disc will continue to feed, and it will explode into a red giant prematurely. Because of this, it will be easy to discover what is happening.

The researchers believe it would be useful to further investigate the relationship between black holes and stars, as it could help understand how the universe works.
