He suggests, for example, going down into the Gran Sasso lab to better detect the signals which he proposes should add up to 511 keV (when measured across a full solid angle). I get the impression he understands the DDL hydrogen to be passing *through* the earth, as one would expect of dark matter. This move raises a challenge to be addressed. A DDL hydrogen atom is baryonic matter and can reasonably be expected to approach the behavior of a neutron. I would expect the significant amount of DDL hydrogen dark matter passing through the earth to be equivalent to a high neutron flux, causing all kinds of capture events. Va'vra mentions in passing that maybe such capture events would be unlikely because of a small dipole moment. But I think this is just a way to have things both ways. Even if we suppose that the DDL hydrogen-capture cross section is smaller than that for a neutron, one presumes it would still be nontrivial. (Mills's theory must also address this challenge.) Eric
