Hi Daniel,
Do you know Nikodem Janusz PopΕawski?
I got very inspired by your lecture and digged a little deaper.
His theory is that every black hole could be a doorway to another universe
and that the universe was formed within a black hole
which itself exists in a larger universe.
I watched a report on arte.
The other thought of mine is. The science wants to proof anything that is not possible
to solve within the three dimensions. Do you think there are humans that have access
to a higher dimension? After all the "normal" human being just uses less than 20%
of the possibility the brain provides. And I doubt that the brain itself plays the leading role.
Just some thoughts

His article "Universe in a black hole" in Einstein-Cartan gravity, is a quite interesting and remarkable one. He claims that: "The conservation law for the angular momentum in curved spacetime, consistent with relativistic quantum mechanics, requires that the antisymmetric part of the affine connection (torsion tensor) is a variable in the principle of least action. The coupling between the spin of elementary particles and torsion in the Einstein-Cartan theory of gravity generates gravitational repulsion at extremely high densities in fermionic matter, approximated as a spin fluid, and thus avoids the formation of singularities in black holes. The collapsing matter in a black hole should therefore bounce at a finite density and then expand into a new region of space on the other side of the event horizon, which may be regarded as a nonsingular, closed universe. We show that quantum particle production caused by an extremely high curvature near a bounce can create enormous amounts of matter, produce entropy, and generate a finite period of exponential expansion (inflation) of this universe. This scenario can thus explain inflation without a scalar field and reheating. We show that, depending on the particle production rate, such a universe may undergo several nonsingular bounces until it has enough matter to reach a size at which the cosmological constant starts cosmic acceleration. The last bounce can be regarded as the big bang of this universe."
That's quite brilliant since he makes some reasonable grounds for terms such as big bang, torsion tensor and cosmic inflation. His equations in the article sound pretty promising in the very sense of science.
Regarding to the dimensional question, The universe has three spatial dimensions (length, width, height) and one temporal dimension (time). This model is not related to our abilities but the very nature of gravity. In our universe, gravity follows an inverse square law, which means that the strength of the gravitational force decreases with the square of the distance between two objects. If there were additional spatial dimensions, the behavior of gravity would be different, and this would likely have observable effects on the motion of celestial bodies and the structure of the universe. The laws of physics are finely tuned for a 3+1 dimensional universe. It's important to note that theoretical physics, particularly in areas like string theory and brane cosmology, does consider the possibility of extra spatial dimensions beyond the familiar three. If such dimensions do exist, they would need to be compactified or hidden on very small scales to be consistent with our observations of the universe. Additionally it would be against the fundamental properties of space. As a macroscopic scale object at regular energies, you are restricted to move and interact in three dimensions of space, and one of time. Unfortunately, despite very intensive efforts spanning several decades, no evidence of these extra dimensions has ever been found. Most notable of these attempts was the failure of large hadron collider to find any indication of higher dimensions.
