How do black holes form, and will the sun eventually become a black hole?

We humans have always been curious about the universe above us, and the stars that we thought were insignificant turned out to be huge, in a way that further stimulated our curiosity, and the powerful forces behind them.Of all these powerful and massive things, a black hole is definitely one of them. It can suck up everything around it effortlessly. So how do black holes form?The reason why the formation of a black hole asks whether the sun will become a black hole is that the black hole itself is also defined as a celestial body.The black hole name intuitively conjures up the image of an undersea vortex, disembodied but with enormous energy, but in fact, the black hole itself is formed from a star.It is also the reason why the discovery of black holes is not the result of observation like most celestial bodies.At the beginning of the last century, scientists working on Einstein’s field equations stumbled upon a unique solution that led to the existence of a new object, a black hole, that gave astronomers new insights into the structure of the universe.In the age of backward technology, it was impossible to directly observe black holes, and it was also impossible to get close, partly because of the distance and partly because of their terrifying eating power.Even light, let alone instruments, couldn’t escape it, and it wasn’t until the spring of 2019 that we got our first glimpse of what a black hole might look like.The black hole does, at least in the image, have a dark center with no discernible structure and a swirling ring around it that looks like a flame.When we say that a black hole is formed when a star loses its original properties, it is actually the result of the end of the life of the star.Specifically, as energy dies, the center of the star becomes hollow and collapses under gravity, and because of the high pressure inside, this process is accompanied by explosions.At the same time, the composition of matter will slowly disintegrate, as particles begin to leave their original positions, and reunite under the pressure of external space-time, forming a new solid structure, which has the embryonic form of black hole.If so, then black holes are no different than any other celestial body that has reached the end of its life, except that the original star is so massive that the process is so dramatic.In the final stage of convergence, the solid structure’s density increases to unimaginable levels until it affects the surrounding space-time by absorbing everything with mass.According to this principle, all stars in the universe can become black holes, including the sun, but is this really the case?The sun is now at the peak of its life cycle and has passed 4.5 billion years of age, according to celestial studies, meaning it will have at least a few billion more years before its lifespan starts to decline. What happens to it then?First, because the fusion reactions have consumed most of its matter and energy, there won’t be much left. There won’t be enough mass for it to go supernova. Most likely, the sun will turn into a red giant.Specifically, because the core collapses under gravity and starts to compress inward, the friction between the particles heats up the object again, and that heat builds up over the course of the contraction, until at some point it goes out of control.At this point it becomes less bright, but at the same time it shrinks further in size. This process is accompanied by a reaction called helium fusion, which results in the formation of large amounts of carbon, which in turn expands the outside of the sun until it becomes a growing object.How big will it get?Calculations suggest it could have reached as far as today’s earth, only by then it would no longer have the properties of the sun and would have morphed completely into a red giant.So will the red giant continue to evolve, also known as a black hole?In fact, there is at least one black hole in almost every galaxy in our universe, and their masses vary greatly, but they exceed those of the Sun by a huge amount, ranging from 990,000 to 40 billion times.You might wonder, don’t black holes suck up anything with mass?And how do they measure their own mass?Black holes themselves are hard to see, so the only way to get a sense of their mass is to look at what kind of objects they suck up and infer their size from those objects.Now, of course, to us, the Sun is already a huge star, but compared to the stars that form black holes, there’s no comparison at all, and of course, some studies have found relatively less massive black holes, with mass multiples between 99 and 2,000, but after dating,It turns out that these black holes formed way back in time, and that the universe was very different from today.Conclusion So, the Sun is a star, but it’s not massive enough to become a black hole at the end of its life. Of course, we can’t say for sure what the sun’s ultimate fate will be, because the universe is changing so fast, and anything can happen.
