The AWT explanation of radiative time arrow (deleted by bentheman)
If the space-time is formed by less or more flat mass/energy density gradient of inertial density fluctuation of Aether, what the heck the time dimension is? And how it differs from space-dimensions?
The inertial energy can spread across the water surface gradient by many ways. But just a few directions are mutually independent: these directions are defining the degrees of freedom for inertial energy spreading, i.e. the symmetry degree of underlying space-time metric and they're can be called the dimensions of space-time. At the case of space-time brane at the water surface the number of spatial dimensions is just two, becase every wave of inertial energy can spread along the water surface just in two mutually independent directions, in which the water surface wave doesn't affect/interfere the another surface waves. This is because the interference will result into another space-time generation formation.
The remaining direction, which is normal to the space dimensions is the direction, normal to the water surface direction. And this is exactly, what the time dimension means in the AWT. The time dimension of space-time are the normal direction, paralel with the direction of inertial gradient, forming the space-time metric. We can see, the time dimensions is just one of many directions of space-time, by the same way, like the space dimension, but because this direction is oriented to space-time gradient, it has always an arrow. The space dimensions, which are planparalel with the space-time gradinent have no such orientation, in fact they're defined just by the directions, which exhibits the lowest anisotropy, i.e. nonequllibrial character of energy spreading.
As we know, the energy spreads along the water surface freely, while the passing of mass/energy through water surface is much more difficult and it's followed by reflection and refraction phenomena. This is the reason, why the travelling in time is so difficult with compare to travelling through space and it's always followed by the substantial loss of energy and mass. The spreading of matter along water surface (the flowing) is more easy, then accross of water surface, but its followed by less or more pronounced formation of standing wave (the deBroglie wave), which results into accumulation of motion energy. This energy is released back during matter breaking, so it's the source of matter inertia.
Surprisingly enough, all the complex phenomena following the matter/energy spreading in the vacuum can be explained by inertial diffusion of matter particles at the water surface, i.e. the artifacts following the diffusion of Aether fluctuations accross the sufficiently pronounced gradients of inertia.
The simulation above models most of complex turbulence and wave phenomena at the liquid surface just by particle simulation of gas. At the moment, this gas will condense by sufficiently high speed, the diffusive dissolution of surface gradient can be neglected and then the inertial waves, spreading along density gradients can remain the conditionally stable. It means, the observable Universe is temporal phenomena, the gradual collapse/expansion of which enables the radiative energy spreading at the distance. So we can explain most of Universe properties just by sufficient accumulation of matter/energy of Aether at the place, i.e. as an effect following the sufficiently large mass/energy fluctuations of Aether.
If the space-time is formed by inertial gradients of Aether and the time dimension is formed by normal direction of this gradient, which testable predictions/explanations can be derived from this simple model? Without such predictions no model of reality can have a deeper sense, as it remains useless with respect of the human's understanding of reality.
Try to propose some! You can still use the water surface analogy. For example, what will happen, if we increase the energy density at the water surface?
