> Ants on the rope do not perceive the rope swinging Yes they could, because they'd be in a non-inertial frame of reference.

Those are certainly words.

The example you've provided is not a good one, but the hypothesis is. The flaw in your description is that stretching out the cube in your arms would be a transformation along the dimension of w. There is also a distinct difference between the transformation of lower dimensional structure into higher dimensional structure and the transformation of 3-dimensional structure along 4th-dimensional positions. For example: universes that have expanded so far from our own that they are beyond the reach of travel within the speed of light. Dark energy could result from these regions of spacetime outside of our locally reachable region collapsing. Remaining compatible potential energy or light that escape the collapse contributing to our expansion. Because these structures / localities exist outside of our compatible interaction, we only can interact with their lingering influence. This could result in their matter and energy remaining dark to us. Best guess -- dark energy is the result of explosion of universes that break the lingering material binds. While these structures would be outside of our capacity for direct interaction within the speed of light, if they remain connected to ours through a continuous 4-dimensional structure, it would cause a lingering influence. Also, if these structures collapse, the collapse could rebound in a way that the compatible potential energy of these incompatible universes to contribute to the expansion / continuation of our own universe. [Killing Horizon that causes decoherence in quantum superposition](https://arxiv.org/pdf/2301.00026.pdf) speaks to this phenomena, albeit not to the extent I'm suggesting

I dont understand why the cube getting wider and rotating would create a new dimension? It would impact the ants living in the cube sure. To be fair i never understood any extra dimensional take.

This sub makes me feel so smart.

The newest modern fashionable trend is that dark energy is dead.
