- Computer simulations reveal that some black holes are formed during supernovas and are propelled into space at speeds of up to 1,000 kilometers per second.
- The explosion and formation of a black hole vary based on the mass and density of the parent star, resulting in symmetrical or asymmetrical explosions.
- The asymmetrical explosions can lead to a powerful kick, launching the black hole into space, but such high speeds are rare and do not pose a significant threat within galaxies.

Scientists have used computer simulations to study the formation of black holes during supernovas. These simulations show that some black holes are formed when stars die and explode, with the black holes being propelled into space at speeds of up to 1,000 kilometers per second. The study suggests that the mass and density of the parent star before it explodes play a role in determining the speed, shape, and size of the explosion and the subsequent formation of a black hole. This research has important implications for understanding the evolution of black holes and their impact on the universe.
The process of black hole formation starts with the explosion of a supermassive star, called a supernova. The core of the star collects leftover gas from its interior, gradually becoming denser until it forms a black hole. The study reveals that the explosion and the subsequent formation of a black hole can vary greatly depending on the mass and density of the parent star. For low-mass and compact stars, the explosion is symmetrical and forms a near-perfect sphere. However, for very massive and less compact stars, the explosion is more asymmetrical, leading to a longer-lasting explosion.
The asymmetrical explosions can result in a powerful kick, sending the black hole hurtling through space at colossal speeds. This kick, similar to the recoil of a gun, launches the black hole into space, sometimes at speeds of up to 1,000 kilometers per second. However, these high speeds are temporary and relatively rare, with the black holes not usually roaming around or causing significant damage within galaxies.
The study involved 20 3-D simulations of supernova explosions, making it the largest set of long-term simulations of this type. The simulations required the use of supercomputers to model the complex interactions and processes involved in the formation of black holes. Previous simulations were too short to provide conclusive results about the ejection of stellar cores into the universe.
While the movement of black holes at such high speeds may be concerning, it is incredibly unlikely that they would come close to our solar system. The vastness of space makes it highly improbable for a black hole to travel into our neighborhood. The study’s findings have broader implications for astrophysical research, as theoretical work like this can aid in understanding the evolution of black holes and their connections to other observed phenomena.
In conclusion, scientists have discovered that some black holes are formed during supernovas and are propelled into space at immense speeds. The shape, size, and speed of the explosion depend on the mass and density of the parent star. These findings, obtained through advanced computer simulations, deepen our understanding of black hole formation and their role in the universe.
