The 6 dimensions attributed to string environment coincide exactly with the number of 6 dimensions we found to exist in QV. In consequence, QV can be considered the medium, in which strings are located, so that any Kaluza-Klein universe that surrounds a particular string is connected to QV through a path to the “other side” that is not directly accessible through spacetime at normal conditions.

On the other hand, it is generally known that entangled particles do display so-called “non-locality”. That is the ability of particles like bosons to get synchronized at very large distances and is interpreted as the immediate interchange of information in a time that is zero for spacetime observers (see for ex. [13] for additional explanation).

With our model of strings surrounded by 6-dimensional QV, particle non-locality can be easily understood as the ability of elementary particles to interact through QV. As above-mentioned, each particle can be understood as consisting of an outer 4-dimensional shell (spacetime side) and an inner 6-dimensional string (QV side). While the outer shell would be responsible e.g. for conventional photon interchange via spacetime, the inner shell would be responsible for mutual “communication” as known to exist with entangled particles. Since communication in 6-dimensional QV happens in a time frame beyond 4-dimensional spacetime, any QV interaction happens in a time that has no meaning for spacetime observers, i.e., the time needed by two entangled particles to interact results to be zero for us and for all of our spacetime devices.

As the result, our universe can be understood as consisting of two different spaces (spacetime and QV) linked together by elementary particles, so that the outer shell of any particle corresponds to the well known 4-dimensional particle, while the inner side is built up by a string surrounded by a local portion of 6-dimensional QV. Generally speaking, any particle can be considered as being a small window to QV.

In the past, there had been no possibility to fuse these tiny windows in order to create a window, large enough to be used e.g. as a path to the “other side”, but the recent discovering of so-called “Bose-Einstein condensation” (BEC) makes it now possible. In fact, at a temperature of only one-billionth degree Kelvin, atoms turn into matter waves and acquire quantum properties. This means that BEC atoms behave like bosons and that they are able to overlap and to produce one single wave, made out of all the small waves that constitute the corresponding atoms.

By fusing supercold atoms into a matter wave, what we are really doing, is eliminating the outer 4-dimensional shell of elementary particles, thus allowing 6-dimensional QV to emerge and to provide quantum properties to the wave, which are per definition usually confined inside QV. Since at BEC, a large amount of particles fuses into one single wave, all Kaluza-Klein universes of the corresponding strings do fuse too and build a path to QV that could be theoretically enlarged and used technologically.

A logic question that remains is, how it is possible to put two spaces together that have each one a different number of dimensions (4 vs. 6)?
