Tiny dark energy puts us near a duality corner

Because the dark energy is roughly 10^-122 in fundamental units—an extreme value second only to zero—the distance conjecture implies our universe must sit near a duality corner, accompanied by a tower of light particles whose mass scales as the cosmological constant lambda to a power of order one (argued to lie between one quarter and one half).

Evidence Quote

the very fact that we have Cosmological constant so small means we must be near one of these corners... there are some particles whose mass scales like that lambda 10 to the minus 122 to some power. Where that power is of order one... this range should be in our universe between a half and a quarter.
