Presuming that the 3 spatial dimensions that we experience in our universe are merely a 3 dimensional brane that floats in a higher dimensional hyperspace and that the proximity of other universes to ours affects physical constants in ours, one may seek evidence for such a presumption. If the distance to a neighboring universe changes, then such things as for instance radioactive decay rates might be different in different parts of our universe. The dependence on the proximity was studied, and estimates made of whether beta-decay following a supernova might be useful as a probe. This work is continuing.
