Someone tried to explain this to me some years ago by putting a dot "A" on the corner of a piece of paper and a "B" on the diagonal corner and folding the paper so the diagonals touched.

He said you don't travel across the paper.

Uh Huh ...

and like the joke about naking your own man from mud, and God said ... "get your own mud" ... who makes the bend in the paper ?

That is precisely what this article assumes may be possible, to "bend the paper".

I will wait for a more concrete proposal than, "It could happen, we have magnets!"

On the grand macroscopic level what makes the bend in the paper is the gravitational properties of matter which curves space and time to its limits in a singularity or Black Hole. Singularities do not necessarily need to be the size of collapsed stars, but can be in the sub-atomic ranges of sizes. Some of the speculative areas of physics envision how space-time is a constant ferment of these singularities constantly coming into and out of existence all of the time, and creeating a wormhole bridging distant parts of the Universe or perhaps eveen different universes in related branes is a matter of expanding some of these quantum mechanical singularities.

One of the intriging questions is whether or not one of these hypothetical warp bubles would exhibit any physical dimensions within normal space-time or would it appear to disappear into a dimensionless point or singularity until the shutdown of the warp bubble?

who makes the bend in the paper ?

Gravity. It bends space-time like a bowling ball on a big sheet of rubber. How do you generate the gravity? Hellifino.
