Yes it is. Measurement is entanglement between the observed system and the observing system. Wave function collapse is an illusion caused by the two systems no longer being separable. They have entered a mixed state. It looks like information is lost in the observed system only because you are ignoring the observer.
- mjfl 8y agoYou've just replaced the problem of collapse with the problem of which universe we transition to. We are only in one.
- atq2119 8y agoTo be more precise, we are in all of them, but our consciousness only perceives one of them. So the real problem isn't in quantum mechanics, it's in what the hell consciousness is and why it works the way it does. However, note that you can have observations performed by a computer which e.g. counts events, and the counter will exist in all "worlds" (branches of the universal wave function, really), while each incarnation of it only "perceives" one such "world". So the physics works just fine even while we don't fully understand consciousness.
- philipov 8y agoWhy is it necessary for consiousness to be any different from that computer counter? It seems to me that the paradoxical idea is not quantum mechanics, but rather conciousness.
- atq2119 8y agoI actually agree with you. If you can accept that consciousness is basically a computer, then there isn't really anything mysterious going on. I probably could have phrased that better.
- rohit2412 8y agoHow does that measurement occur? Since all particles interact via gravitational and electromagnetic Force all the time, why aren't they always entangled. I never see a definition of measurement, or observation.
