Theorem: If Memory Is The Environment And Memory Files Away Every Moment, Then Afterlife Is All Time And Space And Everything It Contains.
Variables/Terms: Environment, Memory, File-Away, Three Dimensional Modeling, Retina, Visual Cortex, Space, Present, and Time.
Environment - The space surrounding a person, animal, or plant where it lives and operates. Data from Oxford Languages. The area or space occupied by or intended for something. The natural world, as a whole. The earthly state of human existence. The environment is the boundless space surrounding a person.
Memory - The power or process of retaining, reproducing or recalling what has been experienced. The ability to store information and retain it from an organism's activity or experience. An image, recollection, or impression of one that is remembered from the past. A device (such as a chip) or a component of an electronic device (such as a computer) in which information can be inserted and stored and from which it may be extracted when wanted. The capacity for storing information. The part of a computer in which data or program instructions can be stored and later retreived.
File-Away - To store information in a file. To get rid of a information by placing it in a file or other storage. To remember a feeling, fact or idea until a later time. For example, file a letter away for future reference.
Three Dimensional Modeling - In 3D computer graphics, 3D modeling is the process of developing a mathematical coordinate-based representation of any surface of an object (inanimate or living) in three dimensions via specialized software by manipulating edges, vertices, and polygons in a simulated 3D space. Three-dimensional (3D) models represent a physical body using a collection of points in 3D space, connected by various geometric entities such as triangles, lines, curved surfaces, etc. Being a collection of data (points and other information), 3D models can be created manually, algorithmically (procedural modeling), or by scanning. Their surfaces may be further defined with texture mapping. By Wikipedia.org 
Retina - The retina (from Latin: rete "net") is the innermost, light-sensitive layer of tissue of the eye of most vertebrates and some molluscs. The optics of the eye create a focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual perception. The retina serves a function which is in many ways analogous to that of the film or image sensor in a camera. By Wikipedia.org 
Visual Cortex - The visual cortex is the primary cortical region of the brain that receives, integrates, and processes visual information relayed from the retinas. Visual information from the retinas that are traveling to the visual cortex first passes through the thalamus, where it synapses in a nucleus called the lateral geniculate. This information then leaves the lateral geniculate and travels to V1, the first area of the visual cortex. V1 is also known as the primary visual cortex. The primary purpose of the visual cortex is to receive, segment, and integrate visual information. The processed information from the visual cortex is subsequently sent to other regions of the brain to be analyzed and utilized. This process is highly specialized and allows the brain to recognize objects and patterns quickly without a significant conscious effort. From National Library Of Medicine - Neuroanatomy, Visual Cortex by Trevor Huff; Navid Mahabadi; Prasanna Tadi. 
Space - The dimensions of height, depth, and width within which all things exist and move. A continuous area or expanse. Space is a boundless, three-dimensional extent in which objects and events occur and have relative position and direction. The limitless three-dimensional extent in which all things exist and move. By www.merriam-webster.com 
Present - At this time: now. By Merriam-Webster.com 
Time - time, a measured or measurable period. There are four dimensions: length, width, depth, and time. Time is the fourth dimension. Time is duration. Time, combined with Space becomes a timespace continuum.
I. The Human Mind - Is It Analog Or Digital?
1. The Difference Between An Analog and Digital Recording
The difference between digital and analog recording is that digital recording uses memory. Take sound for example. An analog recording is like a vinyl record. A digital is like a MP3 recording in memory. An analog recording means imprinting the sound onto a physical medium. For example, a vinyl album is recorded by pressing a stylus into a soft medium. The sound impulses are pressed into the medium physically. The stylus cuts one continuous groove in the medium, circling toward the center. A digital recording, on the other hand, converts sound into electrical impulses. These impulses are then stored in computer memory.
To play back an analog recording we run the stylus down the continuous groove. This imparts a vibration in the stylus that gets amplified, to reproduce the sound. To play back a digital recording when read numbers from memory, convert them back into electrical impulses, and amplify them.
The question becomes, is the human mind digital or analog? Analog believers claim an analog vinyl record has superior sound quality so we must be analog. Digital believers claim that sound quality of a digital recording simply dependent upon the resolution of the recording. Increasing the resolution makes the quality of a digital recording indistinguishable from an analog recording.
One advantage of the digital concept is that it doesn't fade over time. Each time you play back a vinyl record, the recording's groove gets slightly worn and sound quality diminishes. When you play back a digital recording numbers get read from memory so nothing wears down. A digital recording, played 100 years from now, will be the same sound quality as the original recording. A digital recording is characterized by memory. To find out if the human mind is analog or digital we start by taking a close look at the retina of the eye.
2. A Close Examination Of The Retina Of The Eye
The retina of the human eye looks strikingly similar to the digital camera above. This is a take a close look at a section inside the retina of the eye:
The receptive field (right) shown above is where light hits the inside of our eye. Embedded in the receptive field are rod and cone cells. Rod cells (shown in yellow) detect monochromatic vision (black and white). Cone cells detect color. These nerves send impulses to the bipolar cells. There is some logic processing at the bipolar level. Then the output is sent to the ganglion cells where information is processed further. Then the data is sent out the optic nerve to the brain as shown here.
In the retina light and color gets converted into electrical impulses that are transmitted via nerves to the brain. This has the earmarks of a digital recording. What you see is light and color being converted into electrical impulses that transmitted via wires to the brain.
3. Our Field Of Vision
The underlying structure of the eye shows the humans use digital recording techniques. The human mind appears to be digital in nature. While the world may feel analog, the evidence shows differently. When you look closely at the retina of the eye it is apparent that humans are digital. The illustration below shows a section of the retina, at the cell level, converting the environment into electrical data impulses:
Imagine looking at your backyard pool. Your environment, upon close inspection, is made up of tiny dots or pixels as shown by the inset. Each square of color (in the inset) is actually one pixel. The color of that pixel is being picked up by cone and rod cells, processed digitally, and sent out the optical nerve to the brain. In the brain this information is assembled into your environment inside the visual cortex.
4. This Sure Looks Digital To Me
This illustration shows how the human eye and brain work together to produce vision. Light comes into the eye through the cornea, then through the lens, and finally onto the retina. In the retina light is converted to electrical impulses using nerves. The impulses from nerves are sent through the optic nerve into the lateral geniculate nucleus in the brain. From there they are sent to the visual cortex. It is in the visual cortex that the outside world is experienced.
Note: We are using the example of perceiving the environment visually for clarity purposes. This does not imply that non-sighted people record any less information than sighted people. Nor does it mean that non-sighted people experience any less of the environment than sighted people. Non-sighted people experience the same richness of life as sighted people. They merely experience life in a different manner. Their environment is complete in every way.
II. The Human Mind, Where Is It Exactly?
1. Most People Would Agree, The Mind Is Here
We are using a three dimensional model to define the location of the mind. If you ask most people where the mind is, they would respond with this. Most people would agree that the mind is located inside the head. The common conception of where the mind is located is here.
Now we've taken a step back and are looking at the scene from another perspective. This is the same man, in the same scene, only viewed from much further away. Notice the relationship between the mind and the environment. In terms of size, the mind is much, much smaller than the environment.
2. How The Surrounding Environment Is Constructed In The Mind
This is a diagram of the steps required for the brain to perceive the outside word. Light comes in from the environment (1). It passes through the lens and strikes the retina at the back of the eye (2) where it is converted into electrical impluses. The electrical impulses are sent via the optic nerve to the brain (3). They are received by the Lateral Geniculate Nucleus (LGN) (4). The electrical impulses are pre-processed and then sent by the Visual Cortex (5).
Here is a quote from news-medical.net explaining the phenominom is medical terms:
How Is Reality Constructed In The Brain
Light enters the eye and is detected by photoreceptors in the retina. Photoreceptors in the retina transform the light refracted off an object into electrical impulses. These are then transmitted to the lateral geniculate nucleus (LGN) in the hypothalamus, via the optic nerve. The LGN then sends signals to the primary visual cortex in the occipital lobe.
From the primary visual cortex information about the object, such as what it is, its location, and its color is transmitted to the higher visual cortices of the brain. The identification and recognition of the object occurs via the 'what pathway'. Signals go from the primary visual cortex and end up in the temporal lobe. The object's location in space is perceived via the 'where pathway'. Signals from the primary visual cortex end up in the parietal lobe.
How is Reality Constructed in the Brain? - By Joelle Hanson-Baiden, BSc
3. Where The Surrounding Environment Is Perceived
Here is another view of how reality is assembled in the brain. On the far left are the rod and cone cells of the retina. They convert light to electrical impulses. These are sent over the optic nerve to the LGN. Then they are sent onto the visual cortex. Notice the outside world is perceived in the visual cortex. Everything to the left is outside the mind. Everything to the right is inside the mind.
It is in the visual cortex where the outside world is actually manifested. Here is a quote that explains visual processing in medical terms.
The visual cortex is located in the occipital lobe of the brain and is primarily responsible for interpreting and processing visual information received from the eyes. The amount of visual information received and processed by the visual cortex is truly massive. Nearly half of the brain is in some way dedicated to vision - either direct communication pathways from the retina of the eyes to the occipital lobe, or to indirect visual processing and visual skills.

4. The Mind Within The Enviornment - The Traditional View
Here is an image of the human mind. The human mind is represented by the tiny red dot, in the head of one of the people in the group. The environment is represented by the large cube surrounding the scene. Imagine the group is standing in a large auditorium. In this view the mind is a small dot surrounded by the large environment.
This view is normally what most people envision in terms of the mind versus the environment. We envision the mind as the grey matter inside our head (shown as a red dot). We envision the environment as our surrounding space (shown as the surrounding cube). This is what most people believe is the relationship betwen mind and environment. They see the mind surrounded by a large outside world.
However, we will recall from Section Three above, that the envioronment is assembled and perceived inside the visual cortex. Put another way, reality is not realized until it is inside the visual cortex. That means the surrounding environment is actually inside the mind. We will show what that looks like next.
5. The Mind Is The Environment - The New "Proof Of Afterlife" View
Here is the more enlightened view of the mind versus reality. Reality is realized inside the mind. You can see from this illustration that the mind actually extends out into the surrounding space as shown.
The concept is that the external enviroment is created inside the mind - the visual cortex. The visual cortex is not just a movie screen where the images of the eyes are projected in a flat two dimensional view. The visual cortex is fully three dimensional and far more complex than previously thought. We are going to take a close look at the visual cortex and its role in creating three dimensional space next.
III. A Closer Look At The Visual Cortex
1. What Happens Inside The Visual Cortex?
The electrical impulses coming into the mind through the eyes, ears, and other senses are not of sufficient resolution to create the vast detailed world around us. If our exterior world was just a stream of impulses coming from the rods and cones of the retina it would be grainy, blurry, and flat. To create the infinitely detailed, three dimensional world around us the mind takes in the data from the outside and recreates a three dimensional model of the world. The world as we experience is built within the Visual Cortex. This is where outside reality is realized.
The process the mind uses to create our world is called modeling. Modeling is the building of a three-dimensional model of the environment. This is the only way our world can be created using the limited information it has to work with. Modeling is done using three-dimensional modeling software like Blender. When you first open the software, you have an empty three-dimensional world. Modeling is the process of adding objects into this world, eventually creating a fully detailed three dimensional environment filled object, textures, and color. The Visual Cortex does this on the fly, meaning it creates the three-dimensional model of reality as fast as it is presented.
2. A Look At Three Dimensional Modeling Inside The Visual Cortex
This is a detailed look at the processing taking place within the Visual Cortex and its associated structures. The Visual Cortex is not just a pass-through of visual data. There is heavy processing that takes place. It builds our three dimensional world, filling the in blanks in data to create a complete, unbroken, and resolution independent surrounding environment.
Here is the processes taking place:
1) Raw electrical impulse data comes into the visual cortex through the senses.
2) Once inside the visual cortex, a three-dimensional modeling process takes place. This is similar to the computer modeling process that takes place when a graphic artist creates an environment for a video game. The Visual Cortex creates a geometric model of our surrounding environment as unfolds before us.
3) The three-dimensional model is moved into memory as a file in a computer. This model is a resolution independent, meaning it will remain sharp and clear no matter how close you look. It is complete and detailed in every way.
4) The three dimensional model of the Visual Cortex is presented to the mind as reality. It is here, in step 4, where we actually experience reality. This is not a copy of reality. This is our reality.
3. A Complete View Of We Experience Reality
Below is a more complete view of visual processing. Notice how we have introduced a virtual reality headset into the diagram. A virtual reality headset is a fully three dimensional projector. It is used to project three dimensional models into three dimensional surrounding space. A carefully crafted three dimensional model, viewed through a virtual reality headset, is indistinguishable from "real" reality.
Here is a true picture of how the mind uses the visual cortex to experience three dimensional surrounding space:
1) Light comes in through the lens of the eye.
2) Light strikes the retina where it is converted into electrical impulses.
3) Electrical impulses are sent through the optic nerve to the mind.
4) They arrive in the LGN where they are preprocessed and sent to the Visual Cortext.
5) Inside the Visual Cortex the incoming electrical impulses are used to build a fully three dimensional model of the outside world using a process called modeling.
6) The geometric three dimensional model is sent to the virtual reality headset where it is projected as your three dimensional enviroment.
We experience reality in the visual cortex, not in the outside world.
4. Is Medical Science Starting To Believe Us?
It may be difficult to believe that the mind completely reconstructs reality into a three dimensional model, instead of just passing optical data directly to the brain like a video. I found this article. It shows that medical science is coming to realize that reality is being reconstructed in the mind, not just projected flat as previously thought.
Imagination and Reality Look Different in the Brain
The occipital lobe sits in the lower, back part of the brain. Containing the visual cortex, this lobe's primary function is to process visual information. The parietal lobe lies above the occipital lobe, and its primary function is to integrate sensory information, such as vision, but also touch and sound. In doing so, the parietal lobe assembles elementary building bricks from so-called "lower-order" brain regions to create concepts, said Daniela Dentico, a researcher at the University of Wisconsin-Madison and lead author on the report.
A leading theory in image processing "posits that our visual mental images are not stored somewhere in the brain, but get actively reconstructed," Dentico told Live Science. The brain does this, she said, by reversing the order it uses for visual perception. She described this as the "top-down" direction, which starts from the big concept and moves back toward the smaller elements.

Quote by Daniela Dentico. Heliyon Neuroscience, ELSEVIER LIMITED MD PhD
The statement that "mental images are not stored somewhere in the brain, but get actively reconstructed" speaks volumes. To me, this is vindication that the brain is not two dimensional in nature. It is three dimensional. Put another way, it means the mind is space. The mind is not a representation of space, it is space. The three dimensional model created by the Visual Cortex is the environment we live within.
5. Where Is The Proof Of The Mind As Space?
If the mind is space as you suggest, then where is the proof? Fortunately there is proof of the mind as space and it is not hard to find. We can find proof of the mind as space in a phenomenon called Out Of Body Experience or OBE. OBE is where you suddenly find yourself outside your body. Medical science is baffled by this. They don't believe your conscious awareness can be outside the body. However about 10 percent of the population has experienced looking at their body from outside their body. Millions of reports of this are strikingly similar. Medical science may be baffled but Proof of Afterlife is not. People find their conscious outside the body because the mind is space. When you find yourself outside your body, you'll know it is true. Finding yourself outside your body is proof that the mind is three dimensional space. This can happen because while you may be outside your body, you are still inside your mind. What can be more evidential than that? The section entitled "Afterlife Evidence Case - Out Of Body Experience (OBE)" provides a illustrated explanation of how OBE provides evidence of the mind as space.
IV. How Memory Captures Reality
1. Absorbing Reality Into Memory
Imagine standing in this backyard looking at this garden as shown below. This is your surrounding environment. Shown here is what you see. The sun is shining. It is a nice day. You are enjoying the view. You can hear the birds chirping and kids playing.
The clock strikes 12:00 noon exactly.
The pixels in our eyes act like the camera CCD and capture the scene. The camera uses a capture program to take the matrix from the CCD into memory. Our eyes take in the pixel matrix of the environment and pass it to the visual cortex our brain. In the visual cortex reality is assembled. This is the point in time where we experience the present moment. From there the present moment gets absorbed into memory.
A digital camera takes a picture when you press the button. It is a one time event. Human memory is capturing reality continuously like a digital video camera. It is taking pictures of reality continuously like a movie. In the section above we looked at one specific moment - at the pool at 12:00 noon. The environment was captured and loaded into memory. However, that was just one moment. Now we want to look at the next moment because we have a brand new environment.
2. Assembing Past Realities Through Time
As we move through time, from environment to environment, moments get captured into the visual cortex, assembled into three dimensional models where they are absorbed into memory. As reality unfolds before us, we create three dimensional reality and store it into memory as shown here:
The frame on the left represents our present three dimensional reality. This is our current reality. It is physically located in the visual cortex. The horizontal line moving back (with arrows) to the right represents past realities that have been filed into memory. Awareness exists at the center of the leftmost current environment. Awareness stays in the present. Realities move progressively back and to the right as they get filed away in memory. Think of these past realities as frames as being filed into memory. The frames of the past move to the right. As time moves, memory absorbs new environments. The dimmed slices represent former present moments that have been filed away into memory.
3. Memory Absorbs Reality As It Unfolds
As realities stack into memory, awareness remains in the the present moment. Awareness stays in the present. This is our point of view throughout life. This illustration shows past realities stacking into memory like frames of a video. Each frame represents a full three dimensional environment.
Reality (the environment around us now) is the present. It is where we are. It is vivid. The further we get away from reality the more memory appears to fade. This illustration above shows reality at 100 percent opacity, frame 2 at 50 percent opacity, frame 3 at 40 percent opacity. This is intended to signify how memories fade as we get further away from them in time. In reality, moments of the past and the moment of the present are identical in quality. It is only our position in time that makes past realities seem to be less vivid. Memory past moments is a perfect bit-for-bit as the reality of the present. It did not fade over time. When you accept this assumption everything comes into focus. In the digital world, copy does not apply. Copy is an analog concept. In the digital world the original and copy are identical. The duplicate is exactly the same as the original in every way. A copy connotes a diminished in the analog world. In the digital world it is a pristine original.
4. The Concept Of Absorbing Space Into Memory Is Profound
What could be larger than the space you are standing within? There is nothing larger than your surrounding space. It is unlimited in all directions.
Yet that unlimited three dimensional space you are living within gets absorbed in total into memory. The entire space gets absorbed into memory as soon as you see it. If your surroundinng space is unlimited in all directions, and it just got absorbed into memory, what does that say about memory? What does that say about the physical size of memory? It is profound to just think about it.
5. The Present As The Leading Edge Of A Time-Space Continuum
Memory is physically large. In terms of the present moment, it is three dimensional space. In terms of time, it is a time space continuum. The present moment, in all its physical size, is merely the leading edge of a vast time-space continuum. Visually memory looks like this:
The present moment is the only moment you experience. It is digital. The present moment goes into memory as a digital copy and it remains that way. Our awareness moves forward in time. That displacement in time makes it impossible to experience past moments. That perception of a moment becoming old is just a perception. That "old" moment is in memory; intact, exactly bit-for-bit as it was when we experienced it. All that is required for that moment to be experienced again is to move our position in time. Because everything is in memory, we can do that.
V. The Relationship Between Awareness And Memory
1. Absorbtion of the Present Environment into Memory
As we move through life awareness stays in the present. Our model of a human computer, consisting of memory space and awareness, is shown here:
The processor is shown by the black dot at the center of the envrionment. The processor operates from fixed location within memory space. The surrounding memory space is the processor's environment. The human mind is made up of awareness, as represented by the processor, and the environment, as represented by accessible memory.
2. How Memory Absorbs Reality
As each moment passes, it moves from being experienced in the present into the past. First the moment is experienced as the present. Then it gets absorbed into long term memory as the past.
You can think of this as the present moment being filed away into long term memory intact. The human experience has depth in time. We will not experience it until afterlife, but our entire history is in memory all the time.
The illustration below shows this happening. This shows how reality gets absorbed into long term memory. Reality is absorbed in its entirety. Every detail of the environment gets absorbed and filed into long term memory. We do not notice this happening. It happens automatically. The environment around us is already in memory when we experience it. As you experience the outside world, it is absorbed into memory. The act of experiencing a moment and absorbing it into memory are exactly the same thing as shown here:
Each reality is filed away in memory on each beat of the clock. There is no evidence that memories of past moments are thrown away by the mind. On the contrary, the overwhelming evidence is that memories of the past are retained by the mind. The fact that you cannot remember a moment of the past as you experienced it the first time does not invalidate this concept. It merely means that you are unable to remember it at this time. Elderly people can recall in great detail moments that occurred 50, 60, or even 70 years ago. Does this mean that the mind retains certain memories and discards others?
I think not. The mind retains all memories intact. Humans memory is all consuming. Like a computer, we retain information absorbed into memory. A computer does not discard information in memory. Likewise human memory does not discard information either. Humans retain experiences. All of them. Nothing is discarded. Everything is in memory all the time.
Reality is being filed in memory as we move through time. As we move forward in time, the next reality is being filed as we go. This is not a recording of reality. It is reality. It is intact as we experienced it. Experiencing reality is filing it away in memory. We experience only the front edge of a time-space continuum that exists within everyone.
3. Afterlife Is An Explosion Of Awareness Throughout Memory
As we approach the end of life we have everything in memory. We have every moment in memory exactly as it was when we experienced it the first time. It is three dimensional, not flat like a movie. This is the potential we carry with us as we move through life. This is the potential we have with us at our last moment of life. At the end of life, awareness explodes everywhere throughout memory.
At the last moment of life, awareness undergoes dimensional change. It goes from position in time to all of time. It goes from position in space to all of space. This transition happens in an instant. Awareness did this by expanding into the memories that we gathered throughout our lifetime. Memory contains everything ever experienced. It absorbed the three dimensional space of every moment as you experienced it. It retained all moments. We carry these memories with us throughout life. We just never realize them during life. At the end of life all memories are experienced. We become aware of them all simultaneously. A that precise moment we become aware of all our memories at once.
VI. Conclusion - Memory, Awareness And Afterlife
To see how memory and awareness work together we have to use geometry. During life our awareness located at in position in time and space. From there we look out at the world. At the same time we are also memory absorbing our surrounding space. Life is made up of memory and awareness, not awareness alone.
In terms of geometry, awareness is our position in time and space. Awareness is our point of view from where we view the universe. Memory, on the other hand, is time and space. Memory is the space and time that surrounded us throughout a lifetime. These two things - memory and awareness - are perfect mathemtical inverses. One is a point in time space. The other is all time space.
We go through life this way since the beginning. At the end of life nothing changes. The time-space continuum, that is our memory, is carried with us into the end of life. At that moment point of view ceases to exist, awareness explodes throughout memory into all time and space. At the end of life we experiencing all time and space and everything it contains.
So how can I explain what this will feel like emotionally? I have a friend I have known since we were young children. My friend has always been the life of the party. He is naturally funny. Everyone likes him. He loves to have a good time. There was nothing my friend likes more than a party. Now he is in bad health. What would I say to him if given the chance? First, I would say when he opens his eyes the pain and suffering he is undergoing lately will be gone immediately. He will be restored to the strength and vigor of our youth. Second, I would say that the moment he opens his eyes he will be invited to ten thousand parties with open arms, joy and love. All his friends will be there. Everyone will be happy. Everyone will be having a good time. There will be no strife, no suffering, and no worry. Everything will be good, as it should be, and it will stay that way. Third, I would remind him that the best still lies up ahead. His suffering will soon be over. This life is temporary. It is but a momentary blip in the big picture of things. It is one hundred years versus an eternity. The big picture is afterlife and it will good. It will be the everlasting fulfillment of everything you ever imagined.
This concludes proof of afterlife by memory.
