Maybe we can not observe higher spatial dimensions, but we can observe a force that seems to propagate in higher spatial dimensions, thus there seems to be evidence of those dimensions.
Light intensity, gravity, and electromagnetism decay at 1/r^2, which is the same rate at which the area of the surface of an expanding 3D bubble grows. So each unit of light / gravity / electromagnetism could be seen as taking up a specific "patch" of expanding area.
However, the strong nuclear force decays much faster than 1/r^2. In fact, at some distance it goes negative and then decays back to zero. This could be (wild speculation) a force that propagates in many more dimensions. And it's not the only force that does this, the weak nuclear force also decays much more rapidly than 1/r^2 with distance.
I'm not a physicist and I would love nothing more than to hear what holes could be punched into this hypothesis.
You may not be a physicist but you’d make a convincing string theorist!
I say that partly pejoratively, with a Sabine Hossenfelder sort of jocular but judgmental tone.
I’m personally excited to see how astrophysicists will take dark matter out of its darkness and cast it into intuitive lights, like some have with the rising dough analogy for cosmic expansion.
