Perhaps our universe is the inside of a black hole and the energy for expansion is coming in from elsewhere, creating new spacetime in the center of our universe from mass/energy absorbed in the outer universe. So the cosmo constant would be proportional to mass absorbed times c^2 divided by the volume of our universe - like air inflating a balloon. Early inflation was caused by the initial absorption of mass, and it steadied down since then limited by the black hole’s singularity “throat” capacity and the available of mass/energy to absorb The fun question is then: is the throat of the black hole that contains our universe also in our universe?
