What happens to us when we die?
Do we go to heaven? Are we reincarnated? Or do we simply cease to exist?
Recently, my grandmother, who raised me, passed away.
I grew up without a mother, and my grandmother treated me as though I were her own child. She loved me, cared for me, and was essentially the mother I never had.
Before I knew it, I had grown older myself and become a full-fledged middle-aged man who looks perfectly at home with a beer in his hand.
And perhaps that's why I've found myself thinking more deeply about death, a question that seems to have no definitive answer.
Of course, my grandmother's passing was merely the catalyst that prompted me to put my thoughts into words.
I've actually spent many years thinking about death and developing my own perspective, long before her passing.
Personally, I don't believe in heaven or an afterlife as described by traditional religions. However, I also recognize that we cannot definitively prove that such places do not exist.
At the same time, I believe there is a possibility that ghosts, or something resembling what we call spirits, may actually exist.
That might sound contradictory.
But to me, the existence of an afterlife and the existence of ghosts are not necessarily the same question.
There's also a familiar idea that human beings are connected to the universe, or that everything in existence is interconnected.
Such expressions are often associated with religion or spirituality.
However, I wonder whether they might take on a different meaning when considered through the concepts of matter and information.
In this post, I'd like to explore my thoughts on death, consciousness, our connection to the universe, and the possible nature of ghosts, drawing on ideas from physics, biology, and information theory.
1. We Have Always Been Part of the Universe
Before considering what happens after death, I think we should first consider where we came from.
The matter that makes up our bodies didn't suddenly appear out of nothing.
If we trace its origins far enough, we eventually arrive at the universe itself.
The matter that would eventually become our bodies existed long before we were born.
And when we die, that matter doesn't simply disappear.
It breaks down, changes form, and eventually becomes part of other substances, organisms, and processes.
In other words, the human form is temporary, but the matter that constitutes us existed before our birth and continues to exist within the universe after our death.
Thinking about it this way, I feel like I can begin to understand the expression, "When we die, we become one with the universe."
This isn't some kind of religious enlightenment.
From a physical perspective, we have always been part of the universe. Perhaps being human is simply one temporary form that the universe's matter takes.
And this leads me to another thought.
Perhaps we don't become one with the universe only after death. Perhaps we've been connected to it all along, even while we're alive.
2. Imagine the Universe as an Endless Ocean
To explain this idea, I'd like to compare the universe to an enormous ocean.
Across this vast ocean, countless waves form and disappear.
Each wave has its own shape, size, and lifespan.
Yet no matter how different they appear, every wave is part of the same ocean.
I wonder if human existence works in a similar way.
Within the vast ocean of the universe, a wave called "me" temporarily forms.
That wave has a unique shape, different from all the others, and constantly changes as it interacts with its surroundings.
For humans, perhaps these changes correspond to growth, experiences, and the development of personality.
And perhaps death is simply the moment when that wave loses its individual form and merges back into the ocean.
The important point is that when a wave disappears, the water that formed it doesn't disappear.
The wave loses its distinct shape, but the water remains part of the ocean.
Similarly, even if the individual existence we call "me" disappears, the things that constituted that existence do not necessarily cease to exist.
This is the basic image I have of death.
But this analogy has another important implication.
The wave was never separate from the ocean in the first place.
A wave isn't an independent object sitting on top of the sea.
It is simply part of the ocean temporarily taking the form of a wave.
Perhaps human beings are no different.
3. The Idea That Everything Is Connected
There's a familiar expression: "Everything is connected."
When people hear this, they might think of spiritual teachings or religious beliefs.
But I don't think the idea necessarily has to be interpreted that way.
For example, we take oxygen into our bodies through breathing and obtain various substances through food.
We use those substances, transform them through biological processes, and eventually release them back into our surroundings.
Our bodies do not exist in complete isolation from the environment.
We constantly exchange matter and energy with the world around us in order to sustain life.
Our actions also affect other people, and those effects can spread further.
Something one person says might change another person's way of thinking, influence their behavior, and eventually affect the lives of people they have never even met.
In other words, although we appear to exist as independent individuals, we actually exist within an immense network of relationships.
This brings us back to the ocean analogy.
One wave affects the surrounding water, and that movement can propagate elsewhere.
Even though individual waves have their own shapes, they are not completely isolated from one another.
Perhaps we, too, exist within one vast universe, constantly influencing and being influenced by everything around us.
So far, this can be understood through matter, energy, and cause-and-effect relationships.
But I'd like to take the idea one step further.
What if consciousness itself arises from some form of information?
And what if that information is not necessarily confined to individual physical bodies?
Could the idea that "everything is connected" apply not only to physical relationships but also, in some sense, to information?
Of course, the fact that things are physically interconnected doesn't prove that consciousnesses are directly connected.
But I wonder whether there might be a possibility worth exploring here.
4. What Is Consciousness in the First Place?
Human beings have bodies, brains, and consciousness.
But this raises a fundamental question.
Does consciousness simply emerge from nothing as our physical bodies and brains develop?
We are born, grow, accumulate experiences, and gradually develop a sense of self.
But what exactly is consciousness?
I wonder whether consciousness itself might be a form of information.
After all, the things that exist in our universe can be described in terms of information.
The structure of matter, its state, position, motion, and even the mechanisms of life.
Human memories, experiences, and thoughts can also be understood from an informational perspective.
If that's the case, could consciousness itself arise from a particular structure or configuration of information?
This is where my personal hypothesis begins.
What if the information necessary for consciousness doesn't necessarily exist only inside living organisms?
The universe contains an immense amount of information.
Could consciousness emerge when information accumulates, changes, and reaches certain conditions?
Perhaps, during the formation of a living organism, particular information becomes associated with its physical structure, giving rise to consciousness.
I wonder whether the physical body and consciousness might influence each other, developing together over time.
If this hypothesis were correct, perhaps our consciousness wouldn't be completely separate from the information that exists throughout the universe.
However, the existence of information in the universe and the idea that human consciousness is directly connected to the universe as a whole are two different claims.
At present, there is no established evidence demonstrating such a connection.
This is simply a hypothesis I've developed through my own thinking.
5. Where Does Consciousness Go When We Die?
When the body dies, brain activity eventually ceases.
It seems reasonable to assume that the consciousness we ordinarily recognize as "me" also disappears.
When I die, there is no guarantee that my current personality, memories, or self-awareness will continue to exist.
But if consciousness is constituted by information, what happens to that information?
Perhaps the informational structure that sustained consciousness breaks down when the body dies.
Yet could some of that information remain in the universe in another form?
Let's return to the ocean analogy.
When a wave disappears, the water that formed it returns to the surrounding ocean.
That same water may eventually become part of another wave somewhere else.
But we cannot say that the new wave is the same individual wave that existed before.
Perhaps consciousness works in a similar way.
The possibility that information associated with consciousness might persist is not the same as the survival of one's personal consciousness.
Even if some information related to my existence remains, that doesn't mean I would continue thinking, feeling, or experiencing the world as the same person.
And this is what I find most frightening about death.
We recognize our own existence because we are conscious.
If consciousness disappears completely when we die, then from our own subjective perspective, wouldn't it be almost as though we had never existed at all?
What frightens me isn't simply the death of the physical body.
It's the possibility that the conscious "me" experiencing the world right now will cease to exist.
6. Then What Exactly Are Ghosts?
This brings me to another possibility I've been considering.
The existence of ghosts.
Suppose consciousness arises from information.
And suppose that the information associated with consciousness could, in some form, exist beyond the boundaries of a living organism.
If so, could some kind of informational structure remain after the physical body is gone?
I wonder whether this might be the true nature of what we call ghosts.
In other words, a ghost wouldn't necessarily be a deceased person continuing to exist with the same personality, intentions, and self-awareness they had while alive.
Perhaps a ghost is some kind of informational existence that is no longer bound to a physical body.
And perhaps what we call paranormal experiences occur when human beings somehow perceive that information under particular conditions.
Let's reconsider the idea that everything is connected.
What if the universe is not only a place where matter exists, but also a place where different forms of information are related to one another?
Perhaps the information associated with our existence maintains some kind of relationship with its surroundings even while we are alive.
And perhaps, after the physical body disappears, some of that information could continue to exist in another form.
From this perspective, ghosts wouldn't necessarily be supernatural beings existing outside the universe.
They might instead be some form of information remaining within it.
Of course, this doesn't prove that ghosts exist.
There is currently no established evidence that information constituting consciousness survives the cessation of brain function as an independent, organized structure.
Nevertheless, considering ghosts not simply as the souls of deceased people, but as a hypothetical informational phenomenon, opens up another way of thinking about their possible nature.
7. Could Psychic Abilities Be a Form of Compatibility With Information?
If ghosts were informational entities, another question would arise.
Why would some people be able to perceive them while others cannot?
I wonder whether the concept of "compatibility" might offer a possible explanation.
Imagine that a ghost consists of a collection of information with a particular structure.
To perceive that information, perhaps the human mind would need to be capable of aligning with, or matching, that structure.
I imagine this process as something like a three-dimensional jigsaw puzzle.
The information associated with a ghost has a particular shape or structure.
A person's perceptual abilities might be capable of matching some parts of that structure, but not others.
Depending on how well those structures match, the amount and type of information perceived could differ.
For example, imagine two psychics claiming to perceive the same ghost.
One might describe the appearance of a person, while the other might report hearing a voice or sensing an emotion.
What if they weren't necessarily perceiving different entities?
What if they were accessing different aspects of the same information because their perceptual compatibility differed?
In that case, perhaps people described as psychics are simply individuals who can more readily align their perception with certain forms of information that most people cannot detect.
There might be natural differences in this ability between individuals.
It's also possible, at least hypothetically, that a person's degree of compatibility could change through experience or training.
This idea also connects to my hypothesis that human beings are connected to the universe.
If human consciousness could interact with some form of information existing beyond the individual body, perhaps the nature and extent of that interaction would vary from person to person.
In other words, it wouldn't necessarily mean that only certain people are connected to the universe.
Everyone would exist within the same universe, but individuals might differ in their ability to perceive certain kinds of information.
Of course, none of this has been scientifically demonstrated.
But if we assume, for the sake of discussion, that psychics really do perceive something beyond ordinary sensory experience, this could serve as one possible explanatory model for why their descriptions differ.
8. My Perspective on What Happens After Death
After thinking through these possibilities, I've arrived at a particular way of understanding death, consciousness, and ghosts.
Human beings emerge from matter that already exists within the universe.
Eventually, our physical bodies die.
But the matter that constituted those bodies remains within the universe, continually changing form.
And even while we are alive, we are not completely separate from the universe.
We take in matter through breathing and eating, exchange energy with our surroundings, and influence other people and our environment through our actions.
We exist as independent individuals, but at the same time, we are part of a much larger interconnected reality.
If consciousness arises from information, then even if our present sense of self disappears with the death of the brain, perhaps not every aspect of the information associated with our existence is necessarily lost.
And if some informational structures could exist independently of a physical body, perhaps those structures might be what people have historically called ghosts.
It's also possible to imagine information changing form and, under certain conditions, contributing to the emergence of consciousness again.
However, that wouldn't necessarily mean reincarnation in the traditional sense.
Even if a new consciousness somehow emerged from information related to a previous person, there would be no guarantee that it would be the same conscious individual.
I don't believe there is necessarily a heaven or another world waiting for us after death.
Nor do I assume that deceased people continue living somewhere as the same individuals they were before.
What I'm considering is something more fundamental.
Perhaps human beings, and consciousness itself, are temporary configurations that emerge within the universe.
And perhaps death is the end of one such configuration, as its components continue to change and become part of something else.
There is something important about the expression "returning to the universe."
After all, we didn't arrive here from somewhere outside the universe.
Before we were born, while we are alive, and after we die, we are part of the universe.
What changes is the form of our existence.
Perhaps death doesn't connect us to the universe. Perhaps death simply ends the individual form of something that was always connected to it.
Conclusion
Everything I've written here is speculation, not a scientific conclusion.
We currently have no established evidence that the information constituting consciousness can exist independently of the brain.
Nor is there scientific proof that ghosts are informational entities.
And the fact that things in the universe are physically interconnected does not demonstrate that consciousnesses are directly connected.
But I believe that something being unproven doesn't automatically mean it isn't worth thinking about.
Where did the universe come from?
Why did life emerge?
What exactly is consciousness?
And why are we able to recognize ourselves as "I"?
These are fundamental questions to which we still don't have complete answers.
That's why I want to consider death not merely as the termination of biological activity, but also through the relationship between matter, information, and consciousness.
Just as countless waves emerge and disappear across an enormous ocean, perhaps we too emerge within the universe, temporarily form our own distinct existence, and eventually lose that individual form.
And every one of those waves, despite appearing independent, was always part of the same ocean.
The movement of one wave spreads through the surrounding water and can affect other waves.
Similarly, we influence the people and environments around us throughout our lives.
When I think about it this way, the idea that "everything is connected" doesn't seem like something that should automatically be dismissed as mere spiritual thinking.
We are independent individuals, but we are also parts of a much greater whole.
And if consciousness truly arises from information, perhaps there are aspects of our existence that we have yet to understand.
We emerge from the universe, temporarily form an individual existence within it, and eventually lose that form.
"When we die, we become one with the universe."
That phrase once seemed abstract to me.
Now, I feel as though I'm beginning to understand what it might mean.
But these days, I find myself thinking about it somewhat differently.
Perhaps we don't become one with the universe when we die. Perhaps we have always been one with it, even before we were born, and even at this very moment while we're alive.
What Do You Think?
I'm not trying to prove that an afterlife or ghosts exist.
I'm simply interested in exploring what consciousness really is, and what our existence as individuals means within the universe as a whole.
If consciousness arises from information, does that information disappear completely when the physical body dies?
Could the expression "everything is connected" have a meaning beyond our physical relationships?
And if something resembling ghosts were ever shown to exist, what might their true nature be?
I'd genuinely like to hear different perspectives, whether they come from science, philosophy, religion, or personal experience.
How do you understand death, consciousness, and our connection to the universe?
I welcome different opinions, including criticism and arguments that challenge my assumptions.
