Orbs are an extension of consciousness. When we are not in the physical form, we often travel in a light sphere. It's way beyond the nuts and bolts to understand this kind of science. In the universe we live in, we can measure less than one percent [of existing reality], and physicists believe there's another 99 percent out there we cannot measure. There are other planes, other dimensions, and the orbs are a byproduct of these planes and dimensions.

James describing what Orbs are.
