![]() ![]() But here is good news: our black-hole-Sun will be so small, that “gravity-wise” we would hardly notice any difference. You will not be able to see the Moon and our neighbor planets on the permanently dark sky anymore, only stars. What would it be like for us? Well, the black-hole-Sun will not be giving out any light or heat, so prepare for miserable existence in freezing cold and pitch black environment. OK, let’s imagine for a second that the Sun did turn into a black hole. The cooling down happens so slowly, that astronomers believe that not a single black dwarf has been formed yet.Ĭonclusion 1 : white dwarf and, eventually, black dwarf, is the future of the Sun and most other stars you see in the night sky! stellar corpses that emit no light or heat. With time these objects cool down and become black dwarfs, i.e. no nuclear fusion is happening in their interiors. At the end, these stars leave behind a very dense core, a so-called white dwarf, surrounded by a shell of gas, a planetary nebula. Their cores contract while various outer layers form and continue to expand. When these stars burn up all the hydrogen in their cores, they swell into red giants. Little stars, like the Sun, die in a different way. Only the most massive stars become black holes at the end of their lives. ![]() None of those awful things are going to happen in real life!įirst of all, the Sun is never going to turn into a black hole. What would have happened to the Earth if the Sun suddenly turned into a black hole? That was the most frequent question we’ve been asked this Autumn.Īnd if you are already imagining the Earth spiralling towards the black-hole-Sun, being spaghettified and other similar horrors, you are not the only one! Let us put your fears to rest once and for all. ![]()
