It is also possible that 298 Fl can be synthesized by the alpha decay of a massive nucleus.

In 1904, Hantaro Nagaoka proposed an early nuclear model of the atom, where electrons orbit a dense massive nucleus.

Other possibilities to synthesize nuclei on the island of stability include quasifission ( partial fusion followed by fission ) of a massive nucleus.
5.
In the 1911 Rutherford model, the atom consisted of a small massive nucleus with positive charge surrounded by a much larger cloud of negatively charged electrons.

It has been suggested that such a neutron-rich isotope can be formed by the quasifission ( partial fusion followed by fission ) of a massive nucleus.

On the other hand, we can measure all sorts of other effects of black holes ( rather, relativistically supermassive objects ) : among these, we have pulsar radiation due to accretion; we have several observational signatures associated with active galactic nuclei ( usually postulated to be related to relativistic effects of the massive nucleus ), and of course, we have gravitational lensing.
