Regarding 1), you just need to think about conservation laws as being many worlds "blind". Let's assume that we devise an experiment that we 100% prove would split the universe in 3 versions. Executing that experiments splits world 1 into world 1a, 1b, and 1c. Conservations laws will state that the total energy in world 1a == total energy in world 1b == total energy in world 1c == total energy in world 1. Assume that you have a measurement device that is not "many world" aware, you can only measure the total energy in world 1 - before the experiment takes place - and - depending on which many world "version" you measure afterwards - the total energy in world 1a OR world 1b OR world 1c. According to the measurement device, conservation laws will be respected. Even tho the world was split. Currently, all our measurement devices are not many world aware, and are only able to measure physical properties in one world version. This makes it extremely hard - impossible in fact - to fully prove that other universe exist in parallel. If we were able to build a measurement device that is able to have some kind of "total value across world 1a, 1b and 1c", that would be a game changer, and conservations laws would probably not apply for that device. So far we haven't been able to build one, so conservations laws are considered universal.

This is not an answer to the question. The implication from what you said is that the law of conservation of matter and energy is not true when applied to “universe splitting”. Which comes back to the original question. So where does it come from? I assume that proponents of many worlds have an answer for this, though I don’t know what it is. I am doubtful that it’s “magic” or just “conservation does not apply”. > conservations laws would probably not apply for that device The law of conservation applies to the universe, not the measurement device.
