Consider the possibility of a parallel (or perhaps orthogonal)Universe, also with two distinct charges, but one in which likecharges attract and unlike charges repel. The top picture in thequestion below shows a hydrogen atom from our Universe, in whichthe positive proton attracts a negative electron. The lower pictureshows a positive proton attracting a positive electron in theparallel Universe. (Incidentally, positive electrons can be createdin our Universe. They are a form of anti-matter called positrons.)Would the parallel Universe be different from ours if this were theonly difference? Explain your reasoning, giving an example of hownature would or would not be different.
