Cosmological Constant and Dark Energy has been in the news for months.

I was watching a Brian Greene interview from late 2023 or early 2024.He covered some issues he would talk about in the multi-hour program.He said he needs to explain to people the difference between Dark Energy and the observational evidence for Dark Energy.He never got around to it.I was upset he did not.Because it has been a pretty big problem for people to understand the difference.Do you have a clue, why I feel concerned that NOT ONLY the general public does not understand the nuances, but EVEN those who understand (a little) MORE than the general public fail to understand.It is not about UNKNOWN unknowns.It is not even what the scientific community possesses in the KNOWN UNKNOWNS category.It, actually, it the non-scientific community being very very confused, that has earned my concern.(That is just the beginning of my concerns)(conCERN)

I like Brian GreeneHis book on the Many World's Interpretation, was the one that made the case that eternal inflation was a major impetus for the possibility of the Many Worlds Interpretation being true.(Green accepts its ultimate truth)Green has been accused of being a big promotor of String Theory, when the evidence isn't quite so stellar.Eric Weinstein says Greene and Kaku are "out of control".
