> Heisenberg uncertainty principle is more a statement about the limits of knowledge than about "God throwing dice". This isn't what physicists believe though, Heisenberg uncertainty principle is about a wave not having both a well defined position and velocity. They either drift apart (undefined velocity) or they are spread apart (undefined position). Then the wave collapse keeps the wave together over time by randomly removing parts of it, we have no theory where that isn't random even "many world" means you randomly select one of the branches to follow. We do know for sure that particles are waves that spread out and exist in all of those parts, it isn't just that it represent a point particle with unknown location. And we know for sure that those waves under certain circumstances withdraw from parts and just keep other parts, ie wave collapses. Both of those are easily observed in experiments and not up for debate.
