If we take the Schwartzchild Cosmology at face value we would only ever be able to “pierce the veil” through the boundaries of our cosmos with information/radiation through the Hawking Radiation, at least if the universe containing our local singularity has similar physics at play regarding singularities and the force of gravity.
That said, you could always go “down-well” into a singularity in our universe, but surviving the event horizon as more than particle soup spaghetti is quite a challenge.
nice repost for another community, but not a meme.
