Discovery of matter outside our 3D space before 2031?

Prediction market on manifold. 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.

For example, gravitational interactions with this matter causing discrepancies in galaxy rotation curves or the cosmic microwave background.
