Gramps,
Are parallel universes real?  Do multiple dimensions exist?
Susan, from Winfield, Kansas

Susan,
Parallel universes do not exist. This universe is infinite in its extension, and is forever expanding–not by each body accelerating away from the others, which is a fiction of the theory of relativity, but by continually new creations by the Gods. The macro universe is infinite in its extension, i.e., each astronomical system is a component of a larger system, ad infinitum. This multiplicity of systems being part of larger systems never ends. They are infinite in their extension. Likewise, the micro universe is infinite toward the infinitesimal, i.e., there is no fundamental particle. The smallest particle that can be observed by the most powerful instruments is composed of sub-particles, and so on ad infinitum.
Of course multiple dimensions exist. A one dimensional object is a line, a two dimensional object is a plane, a three dimensional objects is a volume, a four dimensional object is a volume at a given location and a given point in time. Higher dimensions also exist, but they do not apply to physical objects, but rather to mathematical concepts.
