Resolves as YES if there is a 90% consensus among the physics community that there exists matter outside of our 3D space (or 4D spacetime) before January 1st 2031.

In order for this question to resolve as YES, there must be a widely accepted theory relying on the presence of matter outside of our 3D space / 4D spacetime, which explains observable phenomena in our universe. For example, gravitational interactions with this matter causing discrepancies in galaxy rotation curves or the cosmic microwave background.
It seems to be an empirical property of ordinary matter that when you measure the pairwise distances between N local bodies you can always embed them into R^3, that is you can always find N points in R^3 whose distances correspond to the distances you measured. If this property is violated by some kind of matter then I expect endless discussion on whether that qualifies as matter at all.
@mariopasquato I guess if there is a theory suggesting that this other matter shares a common origin (e.g. big bang) as what we observe in our space, then that makes it easier to qualify it as being "matter"
