These are related theories, with a slightly different number of dimensions for the mathematics.

One thing that is common is that there are many unconstrained parameters in these theories, which currently make them a nice theoretical framework, which is not usable for practical purposes.

For this reason, some have suggested that these theories are not (yet) science, as they haven't (yet) predicted the results of experiments, let alone produced results which are more accurate than existing, tested theories.

This could all change if the LHC manages to produce some proton-mass black holes, as accepted theories predict that this should not be possible.
