MWI response: Conservation of energy is not violated since the energy of each branch has to be weighted by its probability, according to the standard formula for the conservation of energy in quantum theory. This results in the total energy of the multiverse being conserved.
This sounds extremely weird to me. Who cares about the total energy of the multiverse? When worlds split, can one world gain energy from another? I thought conservation laws applied to each single worldline as it developed, as it’s the only way we single-world beings could notice and make use of them. So neither the “objection” nor the “MWI response” actually make sense. Or am I misreading the quote?
