Possibilities for fundamental particle/astrophysics experiments at a lunar base

It is suggested that some experiments such as the search for proton decay and for cosmic ray signatures of dark matter particles should be seriously considered in planning the scientific program of a Lunar Base Laboratory. Such experiments could elucidate many of the most fundamental unanswered questions of cosmology and particle physics, but face eventual basic limitations on earth and in earth orbit, respectively. Some of these limitations may be circumvented at a Lunar Base due to the lack of atmosphere and stable environment of the moon. 24 refs
