I have a question regarding the Many Worlds Interpretation(MWI) of quantum theory.(adsbygoogle = window.adsbygoogle || []).push({});

Is there any proposed thought experiment that can/does provide some kind of solid/good proof for the MWI?

I have an idea, an experiment and I am very curious about it's validity/soundness and the consequence if so.

Consider two hollow cones that are joined with each other at their bases. Let the inside surfaces of these cones be perfect/near perfect detectors (for gamma, X-rays or any kind of ionizing radiation). Let one of these surfaces be charged negatively and the other be charged positively. Now at the tip of the cone that is charged negatively (call it the electron cone) place a electron emitter and the tip of the cone charged positively (call it the positron cone) place a positron emitter (the cone surfaces are charged to prevent the particles from hitting their own cones). Now emit the two particles(the electron and the positron) at the same instance from their respective cones (maybe some time lag can be permitted). The electron and the positron would travel as waves right? If so then according to the MWI does it not mean that we would always see a collision of the particles (at every point but in each universe we would see it happen at some single point)? Aren't the two particles going to interact at every possible location inside the two cones because every possibility is realised in MWI? If we see gamma being produced for a certain number of e-p emissions from their respective cones (say a certain percentage of the total times we carry out the collisions) can we say that the MWI is true with some confidence and on the other hand if we do not see very many of the collisions and gamma being produced can we say that MWI is wrong with a certain confidence?
