Good point. If electrons are used in the two-split experiment a brick wall probably wouldn't do, you'd need a metal wall. Brick is a pretty good insulator so you'd end up with 2 small negatively charged spots on the wall in slightly different places; How would you get two charged spots? Would each have charge -e/2? The experiment was originally done with photographic film, so that each electron ionized a silver halide atom resulting in a silver spot on the film. Now it's usually down is some kind of detector that amplifies the effect of each electron. Neither one has anything to do with destroying the electron. the walls would not be the same and so the 2 universes would not be the same and so they would not merge. However if it was a metal wall the electrons would just join the general sea of free electrons in the metal and there is no way even in theory to tell one electron from another. So the walls would have the same charge and mass. But in an entangled electron pair experiment (EPR type) detecting the path of one electron destroys the interference pattern on the other leg. But also just absorbing one electron destroys the interference on the other leg. To maintain the interference you have to absorb the electron at the focal point of a lens so that you not only don't detect the which-way information, you erase it.
