*There is very little point in talking about the Multiverse's total
mass/energy because in General Relativity the conservation of energy is not
conserved, it's not even well defined at the largest cosmic perspective.
Even if someday cosmologists find a way to make it useful at the cosmic
level (the conservation of energy is and always has been useful at the
local level) Many Worlds can accommodate it, but at least at the present
time Many Worlds doesn't have much of a use for the conservation of energy,
nor does any other theory that concerns fundamental cosmology.*
