The relativity theory covers the
macroscopic aspect of the world conceptualized as a flat or curved
hypersurface. However, hardly anybody is
aware that we may incorporate the quantum phenomena into the theory by merely
taking into account the hypersurface's thickness, its microscopic scale. We
call such a unified theory the Grand Relativity Theory (GrRT).
Any physical object should have a thickness a)
regardless of its dimensions; otherwise, it would disappear into thin air. Our
physical space is no exception. The effect of space thickness, yielding a
higher degree of freedom for particles to maneuver, intensifies as we probe to
smaller distances approaching the thickness' magnitude (Figure-1). 
This scenery is spectacularly
demonstrated by the string theory which, albeit of its imperfectness, can
[mathematically] discover the ten-dimensionality of the ambient space. Whether
the string theorists can properly portray such higher-dimensional space or not
is a different story.
GrRT posits, on the contrary to the
classical theory's premise, that the 4-dimensional spacetime doesn't at all
represent the real but the primitive world. Inherently, the spacetime is symmetric,
static and eternal. As such, all of its dimensions are entirely equivalent.
It is only when the spacetime splits
in two b) that the dimensions are differentiating themselves into
spatial and temporal. Following this spontaneously
symmetry breaking, a thin 3-dimensional interface (hypersurface) c)
is taking place in between the two halves of the split spacetime.
Now, the interfacial tension that
holds the interface intact makes the dimensions extending along the
hypersurface tenser and more "tangible" than that normal to
it. We call the above dimensions spatial while the latter we call temporal. The
hyper-interfacial tension which is responsible for this differentiation we
recognize as the Gravity Constant.
The fourth [temporal] dimension
extending normal to the hypersurface manifests the dynamical aspect of the
world. The space thickness measured along this dimension is extremely thin,
around 10 -33 cm or equivalent to 10 -44 second, the
minimum thickness that nature allows, below which space and time have no
meaning.
Because of its small thickness, the
hypersurface is inherently unstable. Such a space barely exists, perpetually
appears and disappears which makes the world extremely dynamic.
The size of the space thickness
which determines the duration of space's presence we call now. Space and the
now are the different aspects of the same thing. We perceive the sequence of
space's appearance, presence, and disappearance as the successive
transformations of the future into now and the past.
Matters exclusively present at now.
They exist only along the thin hypersurface (space), not outside of it, which
is nothing but pure energy d). The parts of the spacetime on either
side of this thin space, we call the future and the past (Figure-2).
The extension of this concept for
higher dimensional spacetime is straightforward, except that there come about
successive spontaneous symmetry breakings. A hypersurface of one dimension
lower than its embedding space, together with its corresponding temporal
dimension, is created every time the split occurs.
Within the ten-dimensional ambient
spacetime which the string theory reveals, a total of seven successive splits
have taken place before our dynamical world comes to the existence. We thus
have seven worlds embedded one within another, each with its corresponding
temporal dimension.
Multidimensional time is still an
alien concept for physicists. Physicists thought that the only vast and
extended world existing in nature is that of four-dimensional. They believe
that time is unique, the only dimension of its kind. The extra-dimensions, if
they exist, should be spatial and curled up into extremely tiny loops.
This premise makes the task of
string theorists extremely untenable as there are around 10500
possible ways on how the extra-dimensions may curl up. Nobody is crazy enough
for not using the Occam’s razor to get rid of such problem and for good.
Notes:
a. A physical object may have some
thicknesses depending on the ambient space dimensions we take into account.
Within our 3-dimensional ambient space, a 2-dimensional plane has one
thickness, while the 1-dimensional thread has two thicknesses.
b.
The energy which is inherently
composed of the opposing components tends to break up into its component, i.e.
the positive and negative energies. When
this happens, the spacetime which is nothing but the geometrical manifestation
of the [vacuum] energy, splits into two halves creating a hypersurface in
between the two.
c. We use the notation of space,
hypersurface, and interface interchangeably. The hypersurface is a
straightforward generalization of the concept from the geometry of surfaces
embedded in the three-dimensional Euclidean manifolds.
d. The mainstream physicists portray
the 4-dimensional spacetime, dubbed the world, as being filled with matters
throughout the full extensions. There are no [microscopic] universal now,
matters existing in the past, now and future "have" an equal reality,
as such that time travel becomes possible leading to paradoxes and chaos.
