Well, one that has a lot of physical evidence behind it, unlike other conjecture.

The article is pure speculation. No actual science behind the core theory other than it doesn't allow one type of seismic wave to pass through and slows anther type, therefore density higher than mantel. And then, suggests it must be liquid iron because of our magnetic field.

So what's your alternative hypothesis that better fits the observations? Don't forget it has to be something that generates a magnetic field, too.
