Nature has provided the solution to this question through the giant matter wave that results from the fusing of individual atoms. This wave can be understood as an “event horizon” at the boarder between spacetime and QV, and resembles in some way the event horizon of a black hole. In this sense, a matter wave (in opposition to a light wave) acts as a large window or path between spacetime and QV. (Light can be understood as consisting of strings that are not connected to QV and that simply “ride” upon spacetime fabrics. This “simple” difference would mark the difference between matter and energy).

In order a large BEC window to be used as a path for devices or probes to explore the other side, we ought to create a BEC that is huge enough for this purpose. Current BEC are very fragile and consist only of a diluted cloud of dispersed atoms. A technically useful BEC-window or “Stargate” should consist of a large dense mass of BEC condensed solid matter, large enough, to provide sufficient space and dynamism for probes coming and going. To achieve this goal, we must improve the current techniques that allow creation of BEC (magnetic traps, laser light spotting, etc.) and use more powerful ones, such as matter blocks submerged in a circuit filled with superfluid (e.g. He-4). (Even if superfluids are no perfect BECs, a counter-flow of such fluids will produce a constant energy loss in matter blocks submerged in that flow, probably until BEC-temperature. In consequence, even with relatively simple technologies, it might be possible to produce large solid BECs, by just using the right technique).

Once a window large enough is achieved, we would dispose of a path to enter macroscopic QV. At this stage, there are two possibilities of using such a Stargate: -

- 1. By using one single window, we would dispose of a path from spacetime to QV and vice-versa.

- 2. By using two windows, we could eventually dispose of a path from one window to the other, without having to cross physically QV.

In the following, we will briefly discuss both possibilities: -

- 1. Vacuum properties as Planck frequency (?_P) reveal that QV is a macroscopic space, full of very strong ZPR, even in the range of gamma particles, as to be expected from the content of mutually anihilating virtual pairs and from the mean radiation frequency ((?_P)^1/2 = approx. 10²¹ Hz). In consequence, any probe or body that entered QV, would be exposed at least to a severe gamma-ray shower that would threaten its integrity. We therefore suggest considering this possibility as a means to send and to receive signals as long as we do not dispose of more details.

- 2. In order to use two windows, they should be synchronized and/or connected in some way in order to achieve parallel functioning. This could be eventually achieved by dividing a BEC block into two smaller blocks, while using each block for a different window. In this case, synchronization would be analogous as with entangled particles. By disposing of 2 windows, each one could be used as entrance and/or exit.
