As you point out, A can function quite nicely with L being zero. Why did scientists reconsider the idea of L at all. Wouldn't it be more reasonable to think that A=D and that L is zero or non-existent?
I realize that you consider this a possible solution but I don't see why it wouldn't be considered the most likely solution.
I too am curious about this. Layman alert, by the way, so correct me where I surely err. Einstein’s original CC (K) is still discounted today, no? His CC was to offset the implications of his own equations to make the universe static as I understood and is not needed in a universe that is slowing its acceleration. Now with the new accelerating model of the universe cosmologists introduced w as this dark energy field. Where does this relate to L and why do we need L in a currently losing battle with w? Is there still a theoretical need for a CC in an accelerating model or do we only need an energy field (w) overcoming gravity?
