Supernovae are more likely than black holes to occur in the universe.

Supernovae are the explosions of massive stars at the end of their lives. They are incredibly bright and can outshine entire galaxies. Black holes, on the other hand, are formed when the cores of massive stars collapse in on themselves. They are much less common than supernovae, but they are still very important objects in the universe.

The probability of a star becoming a black hole depends on its mass. Stars with more than 25 times the mass of the Sun are likely to become black holes, while stars with less mass will become white dwarfs or neutron stars.

Supernovae are also more common than black holes because they can be caused by a variety of factors, including the collapse of a massive star, the merger of two neutron stars, or the collision of two white dwarfs. Black holes, on the other hand, are only formed when the cores of massive stars collapse in on themselves.

So, while black holes are certainly fascinating objects, supernovae are more likely to occur in the universe. They are also more important, as they play a role in the evolution of galaxies and the distribution of elements in the universe.
