A five-dimensional space is a space with five dimensions. If interpreted physically, that is one more than the usual three spatial dimensions and the fourth dimension of time used in relativistic physics. It is an abstraction which occurs frequently in mathematics, where it is a legitimate construct.

The Fifth Dimension is a Plane of Consciousness

But also because quite simply that is what it feels like, a plane. The Fifth Dimension feels like a vast plane that stretches out all around you. Self Realization is the doorway into the Fifth plane of consciousness.

In physics and mathematics, a sequence of Nnumbers can be understood to represent a location in an N-dimensionalspace.

Because light, or energy, in Einstein’s theory comes from the interactions of the electromagnetic force, scientists have searched for over 100 years for ways to unite energy or light from the electromagnetic force with the other three forces, which are strong and weak nuclear forces and gravity. Two theories, independently developed and proposed by German mathematician Theodor Kaluza and Swedish physicist Oskar Klein suggested the possibility of a fifth dimension where electromagnetism and gravity unify.
