[Drawing 1]                        Beneath our universe, there is a 5-D world (hyperspace) with particles that are “virtual” to us, since they cross our universe only from time to time. In this world, there are only quantum waves and ZP-particles. Hyperspace is interfaced to our universe through small windows (fermions) and larger “tunnels” (BHs, Neutron Stars, etc.).

            Beneath hyperspace, there is an absolutely flat universe that represents the, so called, “Big Chill”, since at this mysterious stage, there remains no energy of any kind at all.

            The above mentioned hyperspace model is not an arbitrary model. It is even able to explain cosmology:

            One of the most crucial questions of physics and cosmology is: “Why is our universe 3-dimensional?”. This model shows that our conventional 3-D space is only part of a greater world. Our space seems 3-D to us, simply because the smallest space that can support elementary particles is a 3-D space. But this does not mean that there are no further dimensions - all the contrary. In fact, if we imagine a completely empty space with no particle at all, how many dimensions would this space have? The answer is of course: “infinite”. Infinite, because a space without any particle inside has evidently no “information” about how many dimensions particles need. Therefore, in order to grant in any case a stable universe, space must have the greatest amount of degrees of freedom (dimensions) possible. And this number is certainly “infinite”. Any other universe would be unable to exist since it would be non-compatible with itself.

            In consequence, our universe is 3-dimensional, simply because 3 is the smallest number of dimensions a particle needs to exist. This agrees with the above mentioned hypothesis that particles are nothing else than waves in the fabric of space since any wave has at least 3 degrees of freedom (x, y, z). May be, hyperspace arose from the movement of elementary particles. In a space with a potentially infinite number of dimensions, the universe (the space, where particles are confined) is able to adopt any number of dimensions according to the evolution of the universe itself. It is therefore not negligible to suppose that there can exist phenomena in the universe that needed more than 5 degrees of freedom (i.e. “strings” that are supposed to exist in 11 dimensions).
