:::Well I rephrased it a bit... maybe it is better now but go ahead and tear into it for neutral aspect and so forth. A scientist would indeed 'declare' something if it appeared pretty certain to be a 'fact' http://physics.ucr.edu/~wudka/Physics7/Notes_www/node6.html - It appears that the water there can be measured accurately... and that leads to data... that data can be quantified and judging done... scientifically. The peak idea has pretty much gone from theory to fact as far as I can tell... but maybe, it can be phrased better... and have at it. Thanks. I think the source says has reached a peak and I think I changed it to had for continuity and presentation.
