The mainstream physicists are still unable to
recognize the true nature of space and time, albeit their recognition of the
union of the two. The physicists have taken for granted the union which forms a
four-dimensional continuum as such as representing the actual universe.
Physically, such a continuum should be homogeneous
and isotropic in the sense that all of its dimensions are equivalent. However,
physicists seem to lose their physical sense as they assume that the
four-dimensional continuum has different dimensions. We can see this confusion
from Einstein's statement on the inextricability of the spacetime:" the
non-divisibility of the four-dimensional continuum of events does not at all,
however, involve the equivalence of the space coordinates with the time
coordinate. On the contrary, we must remember that the time co-ordinate is
defined physically wholly differently from the space co-ordinates"1.
The dimensions of such spacetime continuum should
be equivalent and their intrinsic nature is [undivided] time-like in a sense
that there is no present, past, nor future a). It is precisely the condition which prevails in
the world model (spacetime) that
mainstream physics have adopted. The notation of [unsplit] spacetime is better
to be replaced by the 'eon' which is more appropriate to describe such
undivided time which is quasi-eternity (Figure-1).
Einstein himself was worried about the absence of
the concept of Now in modern physics as he said to his friend philosopher
Rudolf Carnap. The latter wrote2:"… Einstein
explained that the experience of the Now means something special for man,
something essentially different from the past and the future, but that this
important difference does not and cannot occur within physics [… ], so he
concluded that there is something essential about the Now which is just outside
the realm of science".
It is the background why physics is now in crisis.
Creation by Separation
Physicists are forced to set up a fundamental
structure consisting of light cone at every point within the spacetime for the
purpose to establish order within otherwise a chaotic world model. The physicists have to establish such odd
construction to preserve the causality because they miss identifying a critical
step within the chain of the creation process, i.e., the act of separation, a
common phenomenon in physics, which is
often called "symmetry breaking."
At school, we have learned this separation
phenomenon, for example, in the electrical process where equal amounts of
positive and negative electricity form if we rub a glass rod with a piece of
silk. The glass rod becomes charged with positive electricity, and we find a
precisely equal negative charge on the silk. This empirical fact shows that
friction does not generate but only separates the two kinds of electrification
d).
We may think this positive and negative electricity
as two fluids that are present in all bodies in equal quantities. In
non-electrical neutral bodies, they are everywhere present to the same amount
so that their outward effects are counterbalanced. In electrified bodies, they
separate. One part of the positive electricity has flowed from one body to
another, just as much negative has flowed in the reverse direction 3.
It is just like the separation of oil and water
where we can observe an interface taking place between the two.
Geometrically, we can imagine that the nature of
dimensions along the interface is different from those within the bulk of oil
and water because of the tension that arises at the interface.
Analogous to this three-dimensional oil-water
system, we may posit that the nature of the gravity constant in our
four-dimensional world is nothing but the interfacial tension of the
3-[hyper]interface.
Transversality of Light and Hypersurface
The concept of hyper-interface or more generally
the hypersurface can be borne out based on the phenomenon of transverse waves.
The weird phenomenon that hardly anybody thinks about is the transversality of
light waves in which particles vibrate at right angles to the direction of
propagation of the wave. The transverse
waves are taking place either on a surface of a liquid (water wave) or as the
vibration of a stretch string, and not in the interior of a substance (body).
However, as light waves propagate in the [interior of] space, there should be
an explanation of this paradox.
Numerous experiments have proved the transversality
of light waves. It should lead us to the conclusion that the medium wherein the
light propagates should be surface-like. How come that it could be? We live in
the interior of a body, not on the surface of something.
The answer lies in the concept of hypersurface that
the mathematicians have introduced as a point of departure in the
generalization of the concept of space, long before physicists surmise the
multi-dimensionality of the spacetime. We may conceptualize the space as a 3-manifold as a 3-hypersurface embedded in a
4-enveloping space. We can easily extend this concept to any higher
multidimensional space (Figure-3).
Now, we have a proper place for light as a
transverse wave to propagate on the hypersurface. It is a three-dimensional
[hyper] surface in which photons vibrate at right angles (along with the time
dimension) to the direction of propagation of the wave across the hypersurface.
From this relativity point of view, we see the space as a 3-hypersurface
vibrating to and fro in the time direction.
As the propagation of light waves indicates, we are
dealing in this case not with waves in the interior of a substance but with
phenomena on a surface (hypersurface or hyper-interface) or motions of whole
configurations (like a vibration of strings). We have already a string theory
which seems going nowhere and now tends to converge into a "brane"
theory. We wish to suggest to shift the theory into a more proper
hyper-interface theory.
It is in this context that we should develop the
current brane theory. The brane is more
like a hyper-interface rather than like a piece of paper floating in the air or
in the bulk of something that conceptualized in the current brane theory.
Besides, the gravity force should act only along the surface of the brane and
not out of it crossing through the higher-dimensional bulk.
