Question

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

Explanation / Answer

The universe would collapse on itself because there would be no electromagnetic repulsion to hold matter apart.

In our universe when you holding two lumps of electron clouds close to each other the electron clouds repel and hold the lumps apart.

In the proposed universe the electron (positron) clouds attract and matter would collapse on itself
