Are Extra Dimensions a Dead End?

Are Extra Dimensions a Dead End?

Extra Dimensions are much talked about. They are central to String Theory. The LHC is looking for them (with no success so far).

Now some think Gravitational Waves may be the key to finding them.

But suppose they did not exist for an incredibly simple reason: at very short distances the concept of dimension itself simply breaks down and gets replaced by something very different.

So we're looking for something that does not exist - literally.
