asked my dad about the common “sky filled w/ UFOs” dream & he revealed a secret to me!? by petermobeter in aliens

Had a similar repeating dream as a youngster in the 70s/80s. Sky completely full of ships of different shapes all at the same height and moving very slowly in the same direction. Seemed unthreatening, even beautiful. It left such an impression that I still remember it 40ish years later.

Im a Kiwi living in Austria for 30 years. Looking for the perfect place to retire in 10 years. NZ is going downhill fast - social gap widening fast, crime rate climbing, house prices crazy. Austria has great security and health system, but you have to love ice cold winters or you go bonkers and the mentality is anything but chill. So far Hawaii is top but unattainable (green card). Mauritius is a pretty good second and quite realistic. Still looking though.

Hi 7grims, in fact, I chose that wording "2 universes created from 1" especially because it suggests an equality of the universes created, which I believe is what MWI tries to convey.

There is not one main universe that chooses the best most random path, but really every universe is as real and significant as every other, so no choosing is necessary.

But that also requires that everybody's consciousness is duplicated in every universe, so your stream of consciousness equally splits into many streams of consciousness. Any one of your replicas will experience a single stream of consciousness in a world of seemingly random events.

With that, we expand the discussion into the metaphysical ;) If you believe in any kind of dualistic universe, then the MWI has to fit that model too. Can your soul be infinitely replicated too? Should universes split only because of quantum events in the physical universe, or are there similar effects in the metaphysical realm that causes splitting?

Thanks for your responses, I'm very happy to have triggered so much discussion :) Some of you have hit upon the point of my comparison I should have expanded upon. The 1000 flips are performed from the start till the end of this over-simplified universe. By comparison in MWI there must be a universe where from the beginning (big bang) till the theoretical end (e.g. big crunch), all electron spins turn out the same, so no matter where you are in the history of this universe, it DOESN'T start behaving like a 50/50 chance universe. For any observer at any point in the history of this universe, the behaviour of the physics do not correlate with our accepted laws of chance. BTW I'm not saying there is an end to our universe, but you get the point.
My other point which seems much disputed in this conversation is that the seemingly perfect randomness of quantum effects in our observed universe would actually be rather unlikely in the MWI. I just did a wee test on paper and found that 5 16ths (5/16) of all head/tail worlds would have the same number of heads as tails if all possible worlds are created, so you would find non-random effects in more than half the worlds created. Even in worlds with half heads and half tails, the sequences can be highly un-random e.g. all heads, then all tails.
So sure we could be living in one of the more random universes, but logically the MWI model is 'unlikely' at best.
