I am New to Your Group as I Just Joined Yesterday.

I am new here, what else is new ? 

Each electron "knows" about both slits;  or  the space path "knows" about the electron going thru space.  Seems it is easier to "know" the path thru space that the electron did go  than to "know" both paths thru the slits that the electron did not go.  How many paths are there thru the second slit that the electron needs to know ?  Space seems to win .   

Hello, back again.  Where did I leave off,  the two slit experiment ?   This is the one where the electron can bump off the walls of the slit some infinite munber of different ways and the materal of the wall isn't in the equation for the probability of that path.   Is QM missing something ?

QM predicts the results of experiments better than any alternative.

That is all science can demand of it.

QM gives the exact same results for either concept.
