To above we further add that, the Theory of Special Relativity and Anharmonic Coordinates play an important role in j-space.     Let us first describe physical picture behind the measurements as they are made in conventional (t, x, y, z) metric, used by Aku.  Consider the following description of field φ at a point (x, y, z) at time instants t and t+δt. We note that when we make the statement that a field exists in the measurement space, we acknowledge the existence of the tangential component of the system.  The normal component or the structure part of the system is assumed to exist, but it is not the part of the field description.  This is an important point to understand.  The system in essence, is an infinite source which is being measured.  When the normal component (i.e. memory of the initial state ) is assumed to exist, it is scalar in nature, whereas the field itself is a vector field described by the tangential component.      The picture is similar to the quaternion structure, but with an important difference.  We note that the information content within the tangential field or a vector field, is much smaller than that of the normal component of the system or a scalar field.  We can  visualize this description in the form of a Hydrogen atom, where an electron is in the orbit of a proton.  We can easily set up any tangential field based on electrons alone.  While describing this electric or electromagnetic field,  the description of proton is not necessary.  Yet when we describe the whole system, protons are also included and consequently energy-scales shift by many orders of magnitude.  The discussion in this blog, refers to fields due to tangential components only.   The memory of the initial state will be accounted for later, when we bring in anharmonic coordinates in the description of  j-space.     When we say that a field is established, in essence we are making following statements, which are true for every time instant in Aku's frame of reference: The origin 0j is established in the measurement space based on VT-symmetry, by Obsc. The curve of least disorder, can be measured, i.e. all the arcs forming the the curve of least disorder can be precisely measured by Obsc.  (Aku is represented by ObsM.) Lorentz Transformation is obeyed by all measurements made by Aku.  The locality condition hold. The structures measured by Aku are conformal and Möbius transformations apply between the structures.  We should note that conformity allows for an unique unit normal vector for every point on a surface. However the normal vector corresponding to a conformal structure, is very different than the normal vector corresponding to the initial state .  The measurement space is homogeneous and isotropic, which means that we will not consider the effect of normal components corresponding to the initial state, while developing the description in (t, x, y, z) metric of Aku. The principles of Group Theory apply.  A very useful example would be the group formed by elliptic curves either in real or complex space. The observers follow the weak cosmic censor conjecture that all physically reasonable spacetimes in Aku's measurement space, are globally hyperbolic. Thus in j-space Aku is always measuring in exterior region-I, of Kruskal-Szekeres Coordinates.   Aku can not measure regions II-IV.1, 2 Finally in the absence of any interaction or source, any arbitrary field F is measured as divergence-less and irrotational by Aku.  These conditions are written as :  divF = 0j and curlF = 0j.  Since 0j is finite per measurements of Obsi, the field F is not necessarily source-free and rotation-free, except for the fact that Aku will measure it as such.  We will discuss this important assumption later down the line.  We will not consider the trivial case for which the value of 0j is null per measurements of each of Obsi, Obsc, and Aku.        Having completed the preliminaries, let us consider the diagram for field configurations at a point (x, y, z) for  time instants t and t+δt respectively, introduced earlier in this blog. We will note that in the absence of any interaction, the value of the field φ does not change with the progression of time.  In fact, the following three cases are equivalent in the absence of an interaction: In other words in j-space, zero interaction means no change in the corresponding tangent field, or equally fine-structure constant α = 0  implies δφ = 0.  Let us now assume that a simple interaction between an electron and a photon takes place, resulting in change in momentum of the electron.  This interaction will result in a change in the field as shown below: Here is an immediate problem.  The measurements are made by Aku who being a macroscopic observer, will not be able to measure the change in field φ due to this simple interaction, as the change itself is very nearly in Planck's domain and well beyond Aku's measurement capacity.   In fact it is almost certain that there are many more than one interaction, in the smallest time interval which can be precisely measured by Aku.      So how do we visualize the measurements made by Aku?  We are forced to move away from "counting" and use some other analytical techniques to understand the experimental results.  In fact, we are moving into the territories of Special Relativity, Path Integrals and Green Functions.  Before we start introducing structures in j-space, we need to understand what information does quantum electrodynamics provide us, regarding the physical world represented by the region-I of Kruskal-Szekeres Coordinates.   To be continued.. ___________________ 1.  Conventionally Aku is allowed access to region-III also, but we have different purpose for region-III in j-space.  In j-space the picture shown for Kruskal-Szekeres Coordinates is in a 2-dimensional plane, without the 3-d light cone. 2. If Aku had to provide the description of the interior region-II as well, we can further postulate that the operators used by either Obsc or Aku, are zero-trace matrices  representing convex surfaces (e.g. Pauli or Gell-Mann matrices).  Adjoints exist and the condition that the sum of probabilities equals to 1 or U †U = 1, is satisfied.  Please note that the region-II represents Planck domain and hence any measurement made by Aku for this region, are #PE < 1 measurements. (#PE1 : Probability Equal to 1 measurement)   *** Previous Blogs: EPR Paradox-I  Nutshell-2015 Information on www.ijspace.org is licensed under a Creative Commons Attribution 4.0 International License.
