The prospect of communication with other universes utilizing High-Frequency Gravitational Waves (HFGWs) is discussed. Global communications via HFGWs were analyzed by us in 2012 . We extended communications involved in that paper to intercommunication with exoplanets within our Universe in 2016 , both of those studies are summarized. Herein we further extend communication to the possibility of interacting and perhaps communicating with other universes – the “multiuniverse connection.” Our method, involving Rigor and Inter-Disciplinary resources, is scientific curiosity satisfied by imaginative reasoning. The recently published Theory of Our Universe by R. M L Baker, Jr.  and a working hypothesis on Non-Varying Rate of-Time (NVRT) Processes, are a result of such reasoning, and are discussed in simplified terms. The Theory involves the rollout of our Universe in space and in time, essentially spacetime itself rolling out. Time rolls out from the smallest meaningful time, termed Planck Time and from the smallest meaningful distance, termed Planck Length (both are quantum-mechanical concepts). They rollout in concert with rate of time starting out extremely fast and slowing and the dimensions or space starting out extremely small and growing. There is no need to assume dark matter or dark energy in this Rollout Theory of our Universe; neither one of which have been independently observed. Furthermore, observations of celestial objects and of their motion leading to the Hubble constant have produce anomalous results that can be explained by this Rollout Theory. The discussion of this new Theory leads directly to the discussion of the osculation points or frontiers we may have with other universes, based on a United States Patent Section on Spacetimeuniverse Geometry . A result is that we propose these osculation points or frontiers might be a basis for intercommunications with multiuniverses. We conclude that an “interdisciplinary” approach to communications is absolutely necessary. Also we strongly recommend to develop HFGW detection and to study their possible laboratory HFGW generation. Einstein was reported to have commented that: “Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand.” We concluded that the future will be forged by innovative, imaginative “out of the box” thinking and we also conclude that this paper embraces these attributes.
