Hi, I've read somewhere that the Quantum Zeno effect, should it really exist, rules out the many-worlds interpretation. However I did not understand the argument (actually there was no argument, seems the author considered it obvious). Could someone please elaborate on this? BTW, what's the current status about the Quantum Zeno effect? I know it has been observed, but I've heard about controversies whether the experimenters really only measured or if they influenced the system in a stronger way.
