I see that, but I don't believe it. I know where the cosmological constant comes from. The field eqs are like diffeqs. They're tensor eqs, but the solutions always have the arbitrary constants arising, as in diffeqs, that must be evaluated. There is no truth to the statement that he "added" something in an arbitrary way to force some belief.

DeSitter's solution is a good fit to the present universe. The constant is zero to something like 55-100 decimal places.

"Einstein retracted Lambda in 1932."

He did not. It's still there and it's zero.

Fair enough.

But constants in differentials are dependent on boundry conditions if I remember correctly.

And whether or not a constant is requisite in todays cosmology says nothing about AE's state of mind does it?
