A few points…
What you describe is known as the “Copenhagen interpretation” of quantum theory. That’s the one that states “nothing is real until someone measures it.” While it is the interpretation used by most physicists, it still does have flaws and it’s share of problems. There’s the “measurement problem” (Google for details) and there’s also the paradox of Schrodinger’s half-dead cat (who’s both dead and alive at the same time until someone observes it…)
As for collapsing the wave only with an mind that’s advanced enough, I’ve not read anything that would indicate that we know where to draw the line. Humans, yes. Animals? Probably. Amoeba? We don’t know. That in itself leads to problems as you can get a universe with different realities that aren’t properly connected to one another. “Wigner’s Friend” is the name given to that particular line of questioning.
It is important to remember that while quantum mechanics is probably the greatest achievement of 20th century physics, it is far from being a complete and finished theory. The math itself is pretty extensive and complete and quite usable as is; but there is still much fudging going on. When QED tries to solve Schrodinger’s wave equation, it gets a bunch of infinities (infinite mass, infinite charge, etc) and gets rid of those by dividing the infinities by one another and basically “plugging” whatever value one wants in there.
Remarkably, that seemingly shoddy math works very well for pratical applications.
I’d just be vary careful of taking all of that as gospel (ha!) because it is certain that physicists of the future will improve, revise and change those theories. Personally, I think that the current “fad” of superstring theory has veered off in a profound dead end. The sooner physicist abandon that theory and start looking elsewhere, the better we’ll be.[/quote]
I agree with all. Thanks for the objectivity here. I have always told my physicist friends and others that I thought superstring theory was off track, a dead end, and yet 90% of upcoming physicists want to study it!
Also, just an addition. The alternates to the Copenhagen interpretation at least currently ALL end up with some form of the multiple simultaneous reality postulate. This model also raises some interesting issues of free will such as whether there is something “special” about our reality. It also almost outright allows for backwards time travel with a clear mechanism that would allow it, and not even a conjecture as to what would prevent it. Even Hawking’s “Chronology protection conjecture” is based on there being 1 true universe, and is simply a conjecture. His suggestion that we should expect backwards time travel to not be possible because it seems to go against human intuition is no more scientific than the conjecture that our reality is special because it seems absurd that there are oh, at least 10^180 different solutions for the universe’s wave function-AT LEAST. (although a possible revision of the meaning of the planck length may decrease that number).
Off track, I am currently trying to model fundamental particles as “quantum wormholes and or pockets” which are brought about by quantum scale black holes (not being in the black holes themselves, but created by their “dents” so to speak. These would most probably connect at least slightly different times as well as places. Just wondering if you have any insight about that.
