Not true. The many-worlds interpretation states that the waveform collapses
upon observation and, at that point, splits into a different world for each
possible observation. If many-worlds were true, it should not be possible
to observe simultaneously wave and particle behavior since by the time you
observe particle behavior, the waveform has collapsed. Recently, I read an
article (which, unfortunately, I can't track down at the moment) where
someone claimed to have devised and performed an experiment (single-photon,
I believe) where he was able to simultaneously see wave and particle
behavior. If true, this would clearly disprove the many-worlds
interpretation without, to my knowledge, calling anything else in quantum
physics into question.
