So I’ve conducted this experiment
the ‘ask an expert’ experiment
– ask a fusion expert if they know about a p + p -> d
– get a response
– point out to them if they can’t answer in the positive about p + p -> d then that’s evidence against there being evidence for p + p -> d
and the result was :
– got no answer on p + p -> d
so the conclusion is :
– this evidence suggests there is no lab evidence for p + p -> d
sorry to all those in my situation looking for evidence on p + p -> d if that’s too indirect for you.
Its like trying to detect neutrinos. Doing it directly is impossible, you have to be content with indirect methods.
