That is exactly how I see it. From computationalism, everything that can possibly happen can be computed ahead of time in a deterministic block multiverse. No need for time, energy or matter- it is entirely mathematical- a 4 dimensional math space (actually pops out of my metaverse` string cosmology). In a deterministic universe consciousness and free will seem to also not be needed. But once the quantum mechanics of energy and matter, along with conservation of mass/energy are introduced, the multiverse becomes unique. That's what physics says. But lately, a strong dose of entanglement is thought to be needed to change quantum probabilities into statistical mechanics, the basis of ordinary thermodynamics.

But say the incident photon has a certain frequency, that is a fixed energy. The detection screen then records only one photon of the same frequency and same energy. Thereby quantum collapse ensures conservation of energy. The infinite number of other worlds still exist mathematically in the Math Space of the block multiverse... But a recalculation, like making a wrong turn, must be done in Math Space to account for quantum collapse. The need for continual recalculations may be the foundation of time.
