Answer:
Yes. I believe there are separate realms or dimensions that exist alongside the reality we live.

Although this may be naivety, I believe that separate realms or dimensions exist alongside the reality we live. For every action, there is an opposite, equal reaction. In this case, any action would be our existence, and the opposite and equal reaction would be the existence of separate realms. If you think about it, why does the earth rotate? What if it spun because another universe is taking its turn?
Another reason could be the planets. Currently, to the <em>abilities </em>of our <em>research,</em> there is no evidence of life on Mars, one of the planets. However, we humans may not have the same abilities as the beings (or not beings) we have labeled as "aliens", even though they do not exist. So, that may include vision. We may not be able to see them because of a law in the dimension.
