More importantly, relativity made precise unexpected predictions which were (long after the prediction) experimentally validated. LENR theory has no such predictions yet.
You are completely wrong.
LENR does make predictions, and they have been confirmed in hundreds of experiments. For example, it predicts that when loading and the other parameters in the McKubre equation are met, the cell will produce excess heat without any chemical changes. If these conditions are maintained, the heat will continue indefinitely, amounting to thousands or in same cases hundreds of thousands of times more than any chemical source of heat, with no chemical changes.
The McKubre equation is empirical, with no theoretical basis, but so was Ohm's law when it was formulated. It may be empirical but it is precise and it predicts behavior closely and (almost) always correctly. It predicts these results, which as you see are highly predictable and uniform:
LENR also predicts helium in the ratio to heat, 24 MeV per atom. Everyone who has checked this has confirmed it, albeit sometimes with broad error margins.
I find your statement "it has no predictions" mind boggling. It is as if you have read nothing about the field.
