We have three types of hypothetical alternate Earths.

1. Quantum Alternate Realities
- The idea that for every action every other possible alternative that could have happened creates an alternate virtually identical reality where those possible events did happen, a web of near infinite quantum realities bubbling out with no end.

2. Multiverse Alternate Realities
- This theory speculates that folling the Big Bang during the brief process of inflation other Universes may have bubbled off of our own during the process or even existed independent of it prior to the event. The Multiverse housing these Universes would, by this principle, be infinite with infinite other Universes each with its own unique properties, matter and laws of physics. Our Big Bang may very well have been nothing more than our Universe bubbling off of another.

3. Alternate Earths in this Universe
- If the Universe is truly infinite then it is a statistic given that a planet identical to our own exists somewhere with the exact same people on it living the exact same lives with countless others of varying degrees of similarity (See original Star Trek).

Everything that can happen will happen and is happening all at once, in fact it already happened and it is over but we have yet to catch up.

>for every action every possible alternative
You're already fucking wrong. The many-worlds interpretation of quantum phenomenon has absolutely no effect on macroscopic events. You flipping a fucking coin is not a quantum event with multiple outcomes, it is 100% determined.

>Multiverse
You're close in that it is theorized that there are other universes where the fundamental forces of nature are different as part of multiversal string theory.

>If the universe is infinite then another earth MUST exist!
Idiotic. The size of a set implies nothing about its contents. There is an infinite amount of numbers between 2 and 3, but none of them are 4.

Youre wrong dude. ANYthing and EVERY thing, every little atomic or subatomic fluctuation spawns an infinite set of universes. I suggest you real Everett's paper on the subject.

Many worlds, as all interpretations, is exactly about quantum effects on a macroscopic scale.

All of them (that I know of anyway) can be applied to the cat inna box thought experiment, that shows us how these quantum effects can play out on macroscopic systems. So many worlds, there's a dead cat in one world live cat in another. Whereas the old standard, the Copenhagen interpretation says that, until observed, the cat is an indeterminate state of aliveness and deadness. Copenhagen may still be the standard desu, many worlders may just be more vocal.

Just go third eye mode and remote view subatomic realms. Its all the same energy, but viewed a different way it becomes its own reality. All the realms are connected in some way. All possibilities exist.

Schrodinger's cat was a thought experiment designed to show that the idea of a superposition is ridiculous. It failed in that, and only showed that superposition on a non-quantum level is ridiculous.

It is not saying that quantum events impact non-quantum events, and it CERTAINLY isn't saying that things like coin flips or (as OP postulated) human decision making is in any way effected by the collapse of the probability function in a quantum event.

How does it feel to be that much of a ignorant contrarian?

What do you make of the double slit experiment?

reading list for anyone interested:
Book of the Damned, Charles Fort
Passport to Magonia, Jacques Vallee
Disneyland of the Gods, John Keel

this stuff goes back as far as mankind does, whether you talk about it in terms of parallel realities and dimensions and quantum physics or angels and demons and elves and demons and angels and djinns

in Iceland it's generally accepted that other realities are overlaid on our own, which is of course interrelated with stuff like cryptid sightings, elves and nature spirits, and aliens.

There's a really cool documentary about it: Enquiry into the Invisible World:
