Could Black holes forge heavier elements that have yet to be discovered? Observations


The heaviest elements known in abundance in nature are forged deep within stars.
These elements are made possible by the high densities/pressures within the stars.
Black holes are known to have a much higher density/pressure than any known star.
Black holes are also known to be a phase of stellar evolution - this suggests that the original star's internal process of forging metals would persist within the resultant black hole.
Scientists have forged synthetic/ephemeral heavy metals under conditions which could hypothetically be sustained within a black hole.


Hypothesis:

Black holes forge heavier elements that have not been observed on earth. The conditions needed to sustain these elements are unique to the black hole, due to its high density/pressures. These conditions can be glimpsed, but not sustained in any experimental context

Has this been hypothesized?

No, the heaviest elements are made on Earth in scientific laboratories, or in the extreme gravity of a neutron star's crust.

Many of the larger elements can be made in supernovae and neutron star collisions, not in stars. It requires extreme conditions for these elements to form.

Black holes are actually very cold, they "absorb" any radiation that passes their event horizon.  Outside the event horizon may be some very hot material, but it is not actually so hot compared to the core of a star.

No, inside the black hole everything falls, and reaches a singularity in a short amount of time.

As above, the conditions beyond the event horizon are unlike anything we have on Earth, because there is the unavoidable singularity.  

After some matter has crossed the event horizon it will certainly come to the singularity. (in the same way as you will certainly reach tomorrow) And as it gets closer the tidal effects get greater, eventually ripping the atoms apart.  The extreme gravity in a black hole will tend to pull matter apart not fusing it to larger atoms.

There may be nucleosynthesis in the accretion disc around a black hole. While the amount of high mass atoms made here is relatively small, it may be useful for the sake of detecting and distinguishing black holes from neutron stars or white dwarfs.
