Is it that we can establish that an electron is at two places at the same time, or that there is no way that we can establish that it is not?
If one is a critical reader of textbooks, one can see that this has been known for a long time and is even worse than described above (women and children effected most).
There is only one electron in the whole universe, but it is everywhere at once. Just read the books. Many if not most describe the electron in the singular; "THE electron..... bla, bla, bla". Now that the secret is out (Bush knew), we're DOOMED!
