Astronomers do not believe the sun will end its life cycle as a black hole because it is not massive enough. Only stars with a significantly greater mass than the sun (typically more than about 20 times the mass of the sun) are capable of collapsing into black holes at the end of their life cycles. The sun is expected to end its life as a white dwarf after going through the red giant phase, rather than becoming a black hole.
