Based on our current understanding of physics, it is highly unlikely that we will be able to invent technology to turn ordinary objects like jacks into black holes. Black holes are formed through the gravitational collapse of massive stars, and the process involves extreme conditions of mass and density.
To create a black hole, an object needs to have a tremendous amount of mass compressed into a small volume. This immense mass causes the gravitational field to become so strong that nothing, including light, can escape its gravitational pull. While black holes are fascinating cosmic phenomena, their formation requires conditions that are beyond our current technological capabilities.
Additionally, attempting to artificially create a black hole by compressing matter to extreme densities would require energy on an astronomical scale. It would be far beyond our current technological capabilities to generate the energy necessary to create a black hole.
It's important to note that black holes are incredibly powerful and have a profound influence on the surrounding space. Manipulating or harnessing the energy of black holes is an extremely challenging and speculative concept, and it would require a deep understanding of physics that currently eludes us.
However, it's worth mentioning that scientific progress is continuous, and our understanding of the universe is constantly evolving. Future discoveries and breakthroughs in physics may reveal new possibilities or technologies that we cannot currently envision. But as of now, the idea of turning everyday objects into black holes or creating them artificially remains purely speculative and beyond our reach.
