Padmanabhan is guilty of another interesting paper - Solution to the cosmological constant problem, http://arxiv.org/abs/1302.3226. Any thoughts?

Well, these sorts of ideas are a dime a dozen, but it's great that it offers a nice connection between the value of the cosmological constant and something that we might hope to observe at some point in the future (the energy scale of inflation).

cosmological constant


Hi Chalnoth,

Would you point out to me what other ideas of this sort exist? His work offers a nice picture, and prediction, of the CC. It is also motivated by well known connection between gravity and thermodynamics. So I'm curious to see what other directions lead to explanations of the CC with as much results and are as well "motivated".

Sorry, I don't recall any offhand. They generally just don't interest me. I just know that I see them relatively frequently.

here is recent article. This one discusses particles creation but parts of it discusses vacuum energy.
