I'm beginning to suspect that I'm rather weird. That's not going to surprise folks, but I'd like to take a quick survey. Note that the following questions are entirely about intuition -- not what you intellectually think, but what, at a *gut* level, seems correct to you, so don't spend a lot of time thinking about it. Yes, I'm being intentionally simplistic in the replies: I'm curious whether, when pushed into a black and white answer about their gut reaction, folks find these ideas sensible.
The Many Worlds Interpretation of quantum mechanics indicates (basically) that everything that possibly can happen does happen: that at each possible moment of variation, the universe "splits", resulting in more universes. The result would be that there are a practically infinite number of universes out there -- indeed, there are a practically infinite number of variations of yourself. Intuitively, does this seem reasonable?
The Strong Anthropic Principle indicates (among other things) that we make the observations we do just because we happen to live in the world where those observations prove true -- that the world seems surprisingly well-suited to our existence because it just happens to be the world in which can exist. Does this sound likely to you?
Some interpretations of physics would indicate that free will as we think of it is an illusion at the physical level: that at a fundamental level, our decisions are just as determined by basic physics as everything else. At a gut level, do you find that plausible?
If all three of the above and their apparently consequence were to be true -- there are an infinite number of worlds, we just happen to exist in one among them, our decisions are just a result of physics, and therefore every decision you possibly could make you *do* make in some world -- do you find this to be a happy prospect, a sad one, or indifferent? (Remember, I'm looking for gut reactions here.)
