So I've been skimming about the Many-Worlds hypothesis and I just have a few questions as a curious student who is at the very beginning of learning physics. So pardon if my knowledge is limited compared to you guys: 1. It talks about wave function not collapsing. But how is this so if wave function does collapse by the subjective observer? Wave function collapse can be observed all the time. 2. Using Schroeder's cat example, what dictates whether an event observed will become branched off into a new reality? For instance, let's say I'm typing right now on my computer on this post. At what exact objective 'point' in time will my reality branch off? Can realities branch off even without performing a cause/effect decision of some sort? And if the branch-off is from causal decisions - what objectively 'senses' when such a decision has been made? If I fire a gun into someone's chest and that person dies, then at that split second down on the Planck scale there is automatically another reality branching off that we cannot observe where the individual survives the process? How is this even possible? At what measurement does the branch-off create another reality? 3. So if there are a seemingly infinite number of realities existing then where are they? At what dimensional or operational plane do they exist at? If we can calculate a FINITE number of particles, atoms in the Observable Universe then are there also an infinite and never-ending number of atoms and planets and Earths ad nauseum being created? Huh? If Time is spherical and not linear in geometry then how does Time conflate or interact with reality branch-offs or wave function continuing ad nauseum with each observable action? How exactly does time play into wave functioning not collapsing. 4. Falsifiability. Can we even falsify or empirically test using some sort of an experiment that wave oscillations intersect each other and cause 'ripples' but on the reality-level. I'm not talking about the Double Slit experiment. I'm talking about using an experiment to show that realities are objective-based 'lenses' of our observation and that they do, indeed, split. Can we show this happen in action? Sorry for the long post, I just want you to hear out on my questions and criticisms. Would love to hear you chew up my responses. I am willing to take criticism for my post as I am no where near as knowledgeable on this field as you so sorry if I made mistakes on some parts in my questions.
