Can one create a black hole when already inside the black hole ?
praveena said:As far as we know a black hole exists in our 3+1 dimensional space but it itself is considered to be in a state known as singularity so its size is infinitly small and does not consume more that one dimension but its strong gravity bends the space around it so much that it pulls virtually everything into it eve the light which makes a dark region around it and creates an optical illusion that the black hole has large sizes.
praveena said:And there also another important thing is! if anything goes into black hole it doesnot exist. the things may converted into neutrons.
Intriguing thought. If a star was in the process of collapsing to start a supernova as it passed the event horizon of a large black hole, what would cause it to cease being able to collapse? Tidal forces pulling it apart? If the large black hole is really large, tidal forces would be fairly small. So I'm not sure about that.Chronos said:The gravity of a black hole inside its event horizon is too strong [remember the part about not even light can escape] to permit gravitational collapse of mass to occur.
The OP question is very interesting one. I think russ_watters is right. What can't prevent the star to become supernova and turned into black hole? For a larger black hole, the event horizon is very far right. So in between before the singularity, or before the final stage star becomes spaghettization, it can collpase into a black hole itself.russ_watters said:Intriguing thought.

Those two options don't exclude each other.Chronos said:All paths inside the event horizon lead towards the singularity. So a particle trying to gravitationally collapse still must move towards the singularity, not towards the center of mass of the region trying to collapse.
Yes, it is theoretically possible for a micro black hole to be created past the horizon of a large black hole. This is known as the "inner black hole" scenario, where a smaller black hole forms within the event horizon of a larger one.
The most likely way for a micro black hole to be created past the horizon of a large black hole is through the collision of two particles with extremely high energy. This could occur in the intense environment near the event horizon of a large black hole.
It is predicted that the micro black hole would fall towards the center of the larger black hole, adding to its mass and potentially increasing its gravitational pull. This could result in changes to the surrounding space and the behavior of matter and light in that area.
No, it is highly unlikely that a micro black hole created past the horizon of a large black hole would pose any threat to Earth. The gravitational pull of a micro black hole is too small to significantly affect objects outside of its immediate vicinity.
Currently, there is no direct evidence for the existence of micro black holes created past the horizon of a large black hole. However, some theories and simulations suggest that this scenario is possible, and further research and observation may provide more evidence in the future.
