However Dark Matter and Dark Energy we have very much detected.
absolutely not!
what we have is a contradiction between the detected behavior of orbiting bodies and the amount of mass that SHOULD be present to account for this behavior
we have a problem. dark matter is a PURELY THEORETICAL construct, that if it were in fact to exist it would account for the contradiction. This is a very very far cry from saying it has been detected.
It’s like saying my car is getting 100 times the mileage that it should. Well if my friendly neighbor was putting gas in my tank every night, that WOULD in fact explain the discrepancy, but it is not at all a proof that that is the explanation. I have in no way, by having that thought, detected my neighbor doing so.
