I am not a physicist and I don't know if that's possible, but seems unlikely, if I understand this statement correctly: "After collapse to the neutron star stage, stars with masses less than 2-3 solar masses should remain neutron stars, gradually radiating away their energy, because there is no known mechanism for further combination, and forces between neutrons prevent further collapse."[0]
Assuming Jupiter turning into a black hole, the radius of it's event horizon would be just 2.2 meters (and that's 8.7 millimeters for Earth and 3 kilometers for the Sun). [1]
That would take forever to pinpoint an object with a radius of a few meters (apart from its existence as a black hole).

- anigbrowl 8y agoIt would indeed take forever, but the idea is exciting both because it would mean rethinking parts of physics and the thrilling possibilities of experimenting on a small black hole and the numerous interesting ways that could go wrong.
- macspoofing 8y agoI'm actually surprised how negatively people are taking this. >but seems unlikely I'm sure it's unlikely, but how great would it be to have a small black hole in our backyard to potentially visit with a probe. >After collapse to the neutron star stage, stars with masses less than 2-3 solar masses should remain neutron stars, gradually radiating away their energy, because there is no known mechanism for further combination, and forces between neutrons prevent further collapse." We don't understand all the mechanisms that lead to black formation. Most likely that kind of black hole would not be a result of neutron star merger or supernova, but maybe it came about through another unknown mechanism (primordial black hole?). How great would that be to find out! >That would take forever to pinpoint an object with a radius of a few meters (apart from its existence as a black hole). Sure, but maybe we could detect it indirectly. Maybe this tiny black hole has moons or satellites that can be detected. Or maybe we can detect it during an asteroid or comet collision. For a non-physicist, you sure have strong opinions about what is possible and not possible.
- dyukqu 8y agoYeah, I do. I'm so glad that you've realized that, I feel flattered.
