Erik Richardson Posted 3 months ago What is the Medium in which Multiple Universes Exist? How do they move around and interact? What is beyond the Multiverse? Fun question. Let's consider this: to imagine a space between them - we'll call them universe 1 and universe 3, for reasons that will be apparent shortly. When we try to break that experience of "spatial distance between two objects" down, inevitably means that some time passes by as we appear to move in relation to other objects. To know we had left our universe (1), the experience of time would change from what it was inside universe 1 to some time flow 2. While in time flow 2, if we seem to move relative to some objects, then we would, in fact be in universe 2. If we then moved from time flow 2 time flow 3 (the next bubble), we would contrast that to time flow 1 and time flow 2. Now if there is a time flow and some objects during 2, then we would be in a universe, not between universes. This is sort of like the geometry axiom that between any two points, there is another point, except writ very large. If there is not a passage of time or movement in relation to objects in our movement from bubble 1 to bubble 3, then it makes no sense to suggest any space between them. Consider that there is no "dead space" in a mountain of soap foam, it's all full of bubbles (you could say the space between bubbles is empty, but if it is a space enclosed by surrounding bubbles, it is, thereby, also a bubble. Of course, universe 2 could be larger, thereby containing U1 and U3, in which case we are not just talking about congruent bubbles, but the possibility of nested bubbles as well. The paradoxes created would resemble Inception with its different scales of time, more than any model of bubbles floating in some substance. Now this would be more complicated, because different laws of physics could be in operation as well, but you get the idea.
