Quote:Is it not invisible? I would say that observing effect is not the same as observing the cause (the force) itself. I was agreeing with everything else you were saying. How was I being disingenuous?
Because one can never detect a force itself, only its effect. Detecting a force itself is a meaningless term. That's what detecting means: you have a detecting apparatus, and it shows an effect. A force is a unifying theoretical concept which is used because it is a predictive description of a large range of different such effects. Whether these forces "really exist" is a philosophical question, not a scientific one.
In the case of dark energy, there is only one effect, and one parameter, but dark energy in general relativity is not (!) a force. It is a contribution to the field equation which drives expansion. It is a very simple thing in theory.
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
