太阳会变成一个黑洞吗

太阳最后会变成一个黑洞吗？答案是：不会。因为太阳的质量比较小，不会演化为黑洞。太阳将在几十亿年后，经过“体积巨大、光芒四射”的红巨星阶段，最后形成一个致密的白矮星。白矮星密度极高，一个质量和太阳差不多的白矮星，大小却只有地球那么大，即太阳直径的百分之一。

Will our sun become a black hole

Will our sun become a black hole? No. Stars like the Sun just are not massive enough to become black hole. Instead, in several billion years, the Sun will cast off its outer layer, and its core will form a white dwarf, a dense ball of carbon and oxygen that no longer produces nuclear energy, which still shines because it is very hot. A typical white dwarf is about as massive as the Sun, but only as big as the Earth, which is one percent of the Sun’s present diameter.
