I admit i do not have a clue, does anyone know what experiments have
yielded some advance for humankind, and if the cost of said experiments
is worthwhile.
your concern is a common one.
before anyone should try to answer your question, i think they should ask you to specify what the "right answer" is.
do you have a threshold, above which "experiments are too costly"?
do you have a threshold, above which "advances have been made that benefited humankind"?
otherwise, nobody should touch this question. it begs for an answer, which will be refuted easily by replying "yes, but that wasn't really worth it."
experiments are experiments. if their outcome were known, they wouldn't be experiments. if their outcome were known, their benefits and cost-effectiveness could be easily estimated. therefore your question would be moot.
if you want guaranteed results from experiments, please avoid the areas of science, politics, humanities, math, etc., etc.
