Question:  Is it possible that another universe could lie beyond the black holes?

Answer:  From what we know abou t the mathematical theory that predicted and
describes black holes, we do not expect there to be anything inside
a black hole except very condensed mass.  We are not sure what the
condition of the mass will be exactly, but we expect it to have
collapsed onto itself under its own weight and that is what is in the
core of the black hole.  There is not much room inside for anything
else, so we do not expect anoather universe inside there.
