>>13775941Metaphysical implications of Many Worlds is obviously that there are many "worlds." But more so, its looking like there's a bigger slice of dimension to our universe that we can't see. Think of how we can't actually interact with our past or future timelines even though we know we're on the timeline axis. Now think of an extra dimension layer on top of that where time is encapsulated within it.
As for how we see time/subjectivity, I tend to think of our timeline as a metaphorical slice of bread. We can think of our current subject time we experience as a metaphorical slices, yet we know that there's an arrow of time in which our subjectivity travels across that line. On an supermarket isle trays, we have many sliced bread stacks layed across in all directions (top, bottom, side, behind, front). MWT can be though of it like that, except there is a shape/direction in which the breads can be organized in. That shape is the shape of the wave function itself. So there's never an infinite worlds, but rather a set of worlds in which there's a limited amount of variance/space.
