If a black hole swallowed the Sun, we would only have 8 minutes before we would notice it. But suppose the Sun swallowed a small black hole: here’s what would happen
The Sun, our precious source of heat and light, collapses into a black hole. Or maybe a wandering black hole comes along and swallows him. No, it’s not the incipit. If a stellar-mass black hole swallowed the Sun, we would only have about 8 minutes before we would notice it. But suppose the Sun swallowed a small primordial black hole. Here’s what scientists think. Primordial black holes are hypothetical black holes that formed during the earliest moments of the Universe. Unlike stellar-mass black holes or supermassive black holes, primordial black holes are “small,” with a mass roughly similar to that of an asteroid and smaller than a baseball. They appear in some theoretical models and have been used to try to explain everything from dark matter to the mysterious Planet eventually you catch one. Stars with a black hole at the center are known as Hawking stars.
What are Hawking stars
A primordial black hole would initially have almost no effect on a star like the Sun. Compared to the mass of the Sun, the mass could be a speck of dust. Such a black hole couldn’t quickly consume much of the Sun. But it would affect things over time. A black hole in a star would consume matter in the stellar core and grow as time passes. If it could grow rapidly, it could completely consume a star. If not, this could still affect the evolution and end of life of the star itself.
So is there a black hole in the Sun?
The study shows that it all depends on the initial size of the primordial black hole. For those with a mass of about a billionth that of the Sun, it could consume a star in less than half a billion years. If that happened, then there should be quite a few solar-mass black holes out there, too small to have formed from supernovae like traditional stellar-mass black holes. If the primordial black hole is much smaller, say less than a trillionth of the solar mass, then things get complicated. The tiny black hole would consume some of the matter inside the star, but not at a fast rate. However, it would stir , heating it more than just melting. As a result, a star might swell to become cooler and redder than normal red giants. All that turbulence in the core could also affect the star’s surface activity. So no, there is no black hole in our Sun. Or if there is, it would have to be extremely small. But maybe there are some Hawking stars out there, and that’s what fascinates scientists. There is always something new to discover in astronomy!
