LENR is a fundamental force of nature. LENR gives liquid hydrogen its incompressibility. We who have been studying LENR understand
While sympathetic to LENR as a possible phenomenon that appears to have gained some evidence of operability here on Earth..... I can assert with considerable confidence that LENR is not a "force" whether it is natural or not. I doubt LENR is responsible for any limit to hydrogen's very substantial compressibility (only exceeded by helium). Blathering about LENR without respect for falsifiability or much concern for formulating hypotheses that even have a remote chance of being any more testable than say psychoanalysis or Marxism (two of Popper's favorites)-- will only harm LENR theory and research in the longer term.
And by the way, the deviation from ideality which allows "ultradense hydrogen" appears is very much a surface-associated phenomenon-- perhaps this is the commonality you wish to identify as "LENR". It is instead most likely a result of restraint of motion not necessarily invoking all new physics. So perhaps you, Axil, meant to write something akin to "surface associated ordering [may] contribute to hydrogen's evident high compressibility in LENR contexts...."
