Q: Is it possible for an artificial black hole to be created, or something that has the same effects? If so, how small could it be made?
In theory, all you need to do to create an artificial black hole (a “black faux”?) If a star has more than 3 solar masses, then as it collapses, on it’s way to neutron-star-density, it becomes a black hole (a black hole with more mass needs less density). There’s some disagreement about the minimum size that a black hole can be. A black hole with this mass would be about 10-47 m across, which is way, way, way smaller than a single electron (about 10-15 m). There’s nothing else in the universe the behaves like a black hole.
