From: Teslaalset * There may still be the issue of sufficient lifetime of UDD to be resolved though.
Yes, it could be short. Has anyone seen recent data on average lifetime from Holmlid? We know that metallic hydrogen, as previously described in the literature, is not stable unless kept under extreme pressure. The assumption has been that whatever species corresponds to UDD is not this kind of metallic hydrogen (the previously described variety) … although it could be metallic. Thus the confusion. There could, in fact, be several varieties of condensed hydrogen which are possible, including whatever Mills’ theory suggests. Holmlid’s UDD is far denser than the metallic hydrogen which is made in a diamond anvil press. That would mean that shock compression is fundamentally more efficient than mechanical compression. One detail which would make my day, and yours too - would be an emission line coming from the decay of the Holmlid version of UDD which matches the 3.5 keV emission line which is turning up everywhere these days in cosmology. This would mean that UDD is probably the same species as “dark matter” and it would provide greatly needed secondary validity to Holmlid’s claims.
