Mathematicians have proposed an alternative explanation for the accelerating expansion of the universe that does not rely on the mystifying idea of dark energy.

Interesting indeed. However, the required coincidence that we are at or near the origin point of the wave raises red flags for me. Of course, EVERY explanation so far raises red flags. At least this idea appears testable (that is, it looks like it makes predictions about things that we should be able to observe to find out if this explanation matches up to reality.

That does seem like a rather unlikely coincidence; but it's certainly possible, especially if such disturbances are common in the universe at large

This hypothesis has the advantage of suggesting a testable physical phenomenon whereas Dark Energy doesn't seem to be much more than a mathematical crutch added to the models to make them fit the observations without any clear ideas on what to look for in the real world

That is a major advantage. From what little I've found on this hypothesis, it looks testable with near cureent technology as well, which means we could know one way or the other on it within a few years.
