What might be driving dark energy expansion of the Multiverse?
Occam's razor suggests that the source of Dark Energy is not from some magical force acting on us from outside our universe. Instead, the most important powerful processes going on in the Universe by far are reactions in which ponderable matter is converted to energy. There appears to be a correlation with the rate at which mass in the universe is being lost.
During the Big Bang, inflation was extremely rapid during matter, anti-matter annihilation.
Today dark energy expansion of space appears to correlate with the rate at which matter is converted into energy in all stellar nuclear reactions and also at the center of galaxy and galaxy clusters during black hole interactions.
Also consider a gravity well as a result of a massive object such as a star, as mass is lost during nuclear fusion the gravity well is reduced and space expands. When a star collapses into a black hole the total mass is reduced as result of a rapid burst in radiation and gravitational waves and again as a result the depth of the gravity well is reduced and space expands, whilst at the same time becoming a black hole singularity.
If the above is true, then perhaps Einstein's famous equation needs some addition terms:
E + (expansion of space) = mc2 + (space trapped inside matter)
At t = 379,500 year after the big bang, the matter which emitted the CMBR photons which receive today was located at a distance of just 0.04144 Gly from our location. At that time, this nearby matter had a recession speed of 66.416c. Now that same matter is located at a distance of 45.277 Gly from our location and today it has a recession speed of 3.133c.
Regarding the galaxy CEERS-93316 which is probably the highest redshifted galaxy detected with the JWST, with a red shift 16.4, the light was emitted 236 million years after the big bang and the distance then was 1.96 Gly and the velocity then was 5.65c. Its distance now is 34.7Gly and its velocity is now 2.4c.

Observable Universe Event Horizon:
If we look at the horizontal "now" line in the diagram of Fig. 1 and see where it intersects the "event horizon" line, we find that this is at a comoving distance of about 16 GLyrs; and since at the "now" instant, comoving distance and proper distance are equal, this also corresponds to a proper distance of 16 GLyrs. So a photon emitted "now" from a point that far away will be on the event horizon and will never quite reach us; a photon emitted just inside that point will reach us very, very far in the future.
