would it not stand to reason that our universe is but a singularity. That is, inside the event horizon of a black hole, that infinite singularity chains exist linking each universe to a corresponding location in another dimension of space time, a continuum of cascading space time relativities. Material example: A small bucket with holes draining into a larger bucket with holes draining into yet a larger bucket with holes with the size of the holes remaining constant. The holes representing a singularity both consuming matter in our universe and expelling it into another and the top of the bucket representing the infinite existing "smaller" unviverses, a spatial singularity incomprehensible from inside the bucket, which may be why we cannot measure nor truly comprehend the size of the universe because there is no size to measure just lack thereof. black holes are represented by the internal portion of the holes consuming (matter and energy) from the bucket(universe) we exist in but not being able to expell it, and a white hole represented by the external portion expelling water into the next bucket but not being able to consume it simultaniously.
time always passes forward, as would explain why matter cannot cross back across either event horizon.
I will submit more as feedback is taken into account

A singularity is a point in spacetime where the known laws of physics break down. A singularity is predicted to exist at the center of a black hole, where infinite gravitational forces compress the infalling mass of a collapsing star to infinite density. These are just mathematical singularities resulting from a division by zero most probably, and do not exist physically. According to the Big Bang model of the origin of the universe, the expansion of the universe began from a singularity. Singularity here means very small, yet not zero.
Our universe is not a singularity, it most probably originated from something closely resembling a singularity.
Wormholes are hypothetical, they need black hole - white hole pairs from the Schwarzschild solution. We have never detected a white hole.
Our universe has at least 10
23 stars. There are many candidates for black holes among these.
Hawking radiation, however, postulates that black holes "leak", so that they will eventually evaporate.
