Well, just because it may exist in only 1 upper dimension does not mean it will not induce curvature on other dimensions. There exists a frame of reference for a object where, say, X=j, where j is some velocity on the x axis and all other vector components (Z, Y, etc.) posses no component of the motion, and would therefore not feel curvature due to the particle energy (if this where the only frame).
However, from an outside observer, Y'=dy/dt. Because time is present in all dimensions, this means time will pass through, causing the curvature induced by object to pass through all dimensions as it crosses through extended space-time.
So, no, the energies existence in a higher dimension would not prevent it from causing sever spatial curvature in other dimensions, which would lead to the formation of a black hole.

I did try to explain how it works with only theory I know of that comes anywhere close to the parameters of this Aether (the description of Aether can even be understood as zero-point energy without much effort), which is the quantum mechanical calculations for zero-point energy (the ones that yield potentials in upwards of 100 magnitudes).
But beyond that (and the game balance hell its use introduces), what does the energies origin have to do with what it does? As soon as it leaves this "Aetherâ€
