PRIDE CHEKERAHe discovered that at higher dimensions, gravity could be
unified with electromagnetism into a single unification. Since
we live in a three spatial dimensional world, this extra fourth
spatial dimension was hidden from us, which means is
compactified into an invisible extradimension.
In 1926, another physicist Oscar Klein gave Kaluza's conjecture
a classical 5-D, a quantum interpretation. Klein put forward this
interpretation considering the newly discovered Heisenberg and
Schrödinger's proposals.
According to Klein, the extra 5th dimension of Kaluza
conjecture was a curled and microscopic dimension we can't
observe. A daily life experience which conspicuous shows this
proposal is as follows:
suppose there is a cylindrical pole proximity to you. As you
observe it, at that nearer view, you will see it in its three
dimensional geometry. Now let say you move a distance far
from that pole. The phenomenon becomes different now; instead
of observing it as a three dimensional cylindrical pole, you will
observe it as a one dimensional line. Considering an ant moving
on the pole, it will be accessing the hidden dimensions to you.
Fig 2 below shows the above phenomenon diagrammatically.
Object ‘a’ is three dimensional object observed from a proximity
distance. Then object ‘b’ is the cylindrical object but is now
being observed from a faraway distance and it seems like a one
