I find it interesting that Wesson, in this recent research, is broaching the idea of a "cosmological constant."
Albert Einstein, whether by instinct or mathematical intuition or whatever, felt pretty sure that a cosmological constant existed. He pursued the quest for it. He did not find it. Late in life, he allowed as how the search for the cosmological constant was the biggest mistake he made in his scientific career.
And it seems the next generation of physicists dropped the matter accordingly.
Then again, just because Einstein couldn't find it, doesn't mean that it isn't real, that it isn't "there."
Maybe P. S. Wesson will have better luck!
If found, it could help to elucidate many currently intractable problems in theoretical physics.... In particular, the reconciliation of the general relativity and quantum theories.
Also, I agree that the cosmological constant could be key in reconciling a number of issues, as you suggest.
Thank you so much for your encouragements, dearest sister in Christ!
