This report aims to establish a foundational framework for the entire discussion by deconstructing the seemingly simple act of 'feeling.' By demonstrating that what we call 'reality' is not a direct perception of the external world but rather a sophisticated construct of the brain, we will clarify the critical difference between external stimuli and our internal experience of them.
The biological process through which we interact with the world occurs in two stages. The first is 'sensation,' the process by which our sensory organs and nervous system receive raw stimulus energy from the environment (e.g., light hitting the retina, sound waves vibrating the eardrum).1 The second is 'perception,' an active process in which the brain organizes and interprets this collected sensory information, reconstructing it into meaningful objects or events.1 In other words, our brain doesn't just see points of light; it recognizes them as a 'face' or a 'cup.'
This perceptual process involves three steps: selection, organization, and interpretation. The brain filters and selects certain stimuli from a multitude based on attention, experience, and needs (selection); it groups stimuli into meaningful clusters according to principles like Gestalt theory (organization); and finally, it assigns meaning based on existing knowledge and expectations (interpretation).4 From this perspective, the 'reality' we experience is not a copy of the external world but the brain's best inference.5
So why can't we 'feel' an atom? This is fundamentally a problem of scale and signal strength. An individual atom is so small, and the force it generates by interacting with a single nerve ending does not cross the 'minimum threshold' required to trigger a neural signal that the brain can register as a sensation.6 The 'touch' we feel when we handle an object's surface is not a single atom, but the brain's interpretation of the collective electromagnetic repulsion exerted by trillions of atoms.4
Extending the concept that the brain is an active interpreter rather than a passive receiver leads us to the fact that the brain can generate perceptions even without external sensory input. This provides a crucial clue for understanding reports of supernatural phenomena.
First, we must clearly distinguish between 'illusion' and 'hallucination.' An illusion is a misinterpretation of a real external stimulus. For example, seeing a coat rack in a dark room as a human figure is an illusion. In contrast, a hallucination is the perception of something in the complete absence of an external stimulus.7 Seeing a human figure in a brightly lit, empty room would be a hallucination.
A hallucination is not a mere fantasy but a real perceptual experience generated by the brain's own activity. It can be triggered by brain damage, certain drugs, sensory deprivation, extreme stress, or sleep deprivation.7 The brain's internal activity alone can create an experience that is subjectively indistinguishable from a perception caused by an external event. Therefore, the subjective experience of 'feeling a ghost'—seeing a figure, hearing a voice, or feeling a cold spot—can be explained as a complex hallucinatory phenomenon. The human brain has evolved to be highly adept at finding patterns and detecting agents in faint signals for survival, and this system can sometimes misfire, causing it to 'perceive' an intelligent being that is not actually there.4
At this point, we must clarify the epistemological difference between the reality of an atom and the reality of a ghost. This is a core distinction that runs through the entire report.
The reality of the atom was not established because we can directly 'feel' it. The existence of atoms is confirmed through a vast, cross-verified web of indirect but objective, reproducible, and quantitative evidence—from chemical reactions and Brownian motion to direct imaging via Scanning Tunneling Microscopy (STM).10 This is based on scientific evidence.
On the other hand, the 'evidence' supporting the existence of ghosts is almost entirely based on 'anecdotal evidence' derived from personal, subjective perceptual experiences.13 While these experiences are very powerful and real to the individual, they cannot be objectively verified or reproduced by a third party in a controlled environment.14
The key difference is this: the existence of the atom is a conclusion derived through the scientific method, independent of any individual's subjective state. In contrast, the existence of a ghost is asserted based on a subjective state, and as we have seen, this subjective state (perceptual experience) can be sufficiently explained by the known functions of the brain without postulating an external cause. Therefore, the problem is not to explain 'ghosts' but to explain the 'phenomenon of experiencing ghosts,' and neuroscience already provides a powerful explanatory framework for the latter.
Let us now take the user's hypothesis seriously and treat it as a physics problem. If a ghost were a physical entity composed of specific particles, what properties would those particles need to have? Using the Standard Model, the foundation of modern physics, as our benchmark, we will explore the immense theoretical challenges a 'ghost particle' would face.
The Standard Model of particle physics is a theory that describes the most fundamental particles that make up our universe and the interactions between them (excluding gravity) with astonishing precision.15 This model is like a verified inventory of the material reality of the universe.
The fundamental particles that constitute matter are fermions, which are further divided into quarks and leptons.16 There are six types of quarks (up, down, charm, strange, top, bottom) and six types of leptons (electron, muon, tau, and their corresponding neutrinos).16 All ordinary matter we encounter in daily life (protons, neutrons, atoms, etc.) is made of up quarks, down quarks, and electrons.18
The forces of nature are mediated by particles called bosons. The electromagnetic force is mediated by the photon, the strong nuclear force by the gluon, the weak nuclear force by the W and Z bosons, and the Higgs boson imparts mass to other particles.16 The existence of every particle predicted by the Standard Model has been confirmed through numerous experiments. Therefore, any newly proposed particle must explain why it has managed to evade all these precise experiments.

Analyzing the properties a 'ghost particle' would need to possess makes it clear why it cannot fit into the Standard Model.
The most fatal problem is the Interaction Paradox. Ghosts are often described as passing freely through solid objects like walls and doors. This implies that the ghost particle must not interact with the strong nuclear force or the electromagnetic force, which hold matter together. However, for a ghost to be seen (photon reception), heard (transmitting air pressure), or felt (stimulating nerve cells), it must interact electromagnetically with the atoms that make up our bodies. This is a clear contradiction. In other words, a ghost particle would have to selectively interact with the human nervous system while not interacting with bricks, a property that is impossible to explain with known laws of physics.
This characteristic is also different from dark matter. Dark matter is also presumed to be an unknown substance that does not interact electromagnetically, but its existence is consistently inferred through macroscopic gravitational effects, such as the rotation speed of galaxies.20 Scientists are searching for traces of dark matter with massive detectors, considering the possibility that it might rarely interact with ordinary matter via the weak nuclear force.22 While dark matter is a 'non-interacting' substance, a ghost particle would have to be a 'paradoxically interacting' one.
In conclusion, a 'ghost particle' cannot be any known quark, lepton, or boson in the Standard Model. It would have to be a completely new type of matter, previously unknown, and interact through an unknown new force capable of distinguishing between a wall and a human retina. This is an extraordinary claim that would shake the foundations of physics.
The hypothesis that a ghost retains the memories and consciousness of its former life faces even more severe physical hurdles. This problem extends beyond particle physics into the realms of information theory and thermodynamics.
In modern neuroscience, memory is a process, not a substance. Memories are physically encoded in the brain through the strengthening or formation of new connections between neurons, known as synapses. The network of neurons that stores a memory is called an 'engram.'25 A single complex memory is stored as a specific pattern of numerous synaptic connections, and consciousness is understood as an emergent phenomenon arising from the dynamic interactions of billions of neurons.5
Physics has revealed a fundamental link between information and energy. According to 'Landauer's principle,' the (irreversible) process of erasing one bit of information inevitably releases a minimum amount of energy into the surroundings in the form of heat, causing an increase in entropy.30 The very act of stably maintaining and processing information requires a physical cost.
Storing the vast amount of information corresponding to a lifetime of memories and a complex consciousness would require an astronomical number of bits. To maintain this information stably in a dispersed cloud of nearly non-interacting particles, without a highly organized and continuously energy-consuming structure like the brain, would directly violate the second law of thermodynamics and the basic principles of information theory. An isolated information system without a mechanism for energy exchange and information processing with the outside world would quickly lose coherence due to interactions with the environment, and its information would chaotically dissipate.
In this section, we shift our focus from theory to practice. How does science 'see' things that are beyond human senses? If a ghost particle exists and interacts with us, why can't our most precise scientific instruments detect it? Here, we will contrast the proven methods of detecting atoms with the persistent failure to detect ghosts, clarifying the standards of scientific evidence.
Examining the principle of the Scanning Tunneling Microscope (STM) provides a concrete example of how science extends human perception into the quantum realm. An STM does not 'see' atoms with light. Instead, it utilizes a quantum mechanical phenomenon called 'quantum tunneling.'11
In principle, a metal tip, sharpened to the size of a single atom, is brought extremely close to the surface of a conductive sample. When a voltage is applied between the tip and the sample, electrons 'tunnel' through the vacuum barrier—which they could not cross according to classical mechanics—creating a tiny current (the tunneling current).10
The magnitude of this tunneling current is exponentially sensitive to the distance between the tip and the surface atoms. Therefore, by scanning the tip across the surface and precisely controlling its height to maintain a constant tunneling current, one can map the atomic topography of the surface by recording the changes in the tip's height.11 This is analogous to 'touch' at the atomic scale, but it is an indirect, quantitative, and reproducible measurement based on well-understood electromagnetic interactions and quantum mechanics.
If a ghost particle can interact with human sensory organs to be perceived, it must logically also interact with scientific instruments. The fact that no such interaction has ever been detected serves as strong evidence against its existence.
For any particle to be 'felt,' it must exchange energy or momentum with the matter of our world. Such an exchange is, by definition, a detectable physical event. The Earth is currently under constant surveillance by a network of ultra-sensitive detectors deployed worldwide. Particle accelerators like the Large Hadron Collider (LHC) at CERN, dark matter detectors built deep underground to capture rare and weak interactions 22, and massive neutrino observatories are all searching for signs of new particles.
Despite decades of such searches, none of these experiments have ever recorded a consistent, reproducible signal corresponding to a 'ghost particle.' This 'great silence' is not merely an absence of evidence but carries significant weight as 'evidence of absence.' It suggests that if such a particle did exist, its interaction would have to be so faint as to be incapable of affecting the human nervous system. In other words, the possibility of it interacting strongly enough to be perceived by humans while remaining undetectable by our most advanced equipment is virtually nil.
The evidence supporting the existence of atoms and the evidence supporting the existence of ghosts differ fundamentally in their type and quality. It is crucial to understand this distinction clearly.
Scientific evidence is empirical, reproducible, obtained through controlled experiments, and subject to statistical analysis. The strength of the evidence is based on the rigor of the scientific method used to obtain it.34 In contrast, anecdotal evidence relies on personal testimonies or individual cases, such as "I saw a ghost." It is inherently subjective, impossible to reproduce, and highly vulnerable to cognitive biases like confirmation bias and logical fallacies like 'post hoc ergo propter hoc.'13
Anecdotes cannot serve as the basis for a scientific claim because they are uncontrolled. A personal account alone cannot rule out alternative explanations like hallucinations, illusions, or misidentification, nor can it determine whether the experience is a universal phenomenon or an isolated case.14 Science demands evidence that withstands systematic attempts at refutation.

| Objectivity | High - Designed to exclude observer's subjectivity |
| Reproducibility | High - Must be verifiable by independent researchers under the same conditions |
| Control | High - Variables are controlled to clarify causal relationships |

| Vulnerability to Bias | Low - Biases are minimized through peer review, blind methods, etc. |
| Predictive Power | High - A verified theory is used to predict future phenomena |
| Basis of Claim | Systematic data, statistical analysis |
In this final analytical section, we will use the tools of the philosophy of science to clearly distinguish what is a subject of scientific inquiry and what is not. We will apply Karl Popper's principle of 'falsifiability,' which separates science from non-science, to the 'ghost hypothesis' and answer the user's question about undiscovered elements.
The philosopher Karl Popper proposed 'falsifiability' as a criterion to distinguish a scientific theory from a non-scientific one. According to his argument, a theory is scientific only if it is, in principle, capable of being proven wrong.37 A scientific theory makes specific predictions that risk failure. If those predictions do not align with observations or experimental results, the theory is falsified.39
This is a crucial yardstick for distinguishing science from pseudoscience. In Popper's view, some theories, like Marxist historical theory or Freudian psychoanalysis, were so flexible that they could explain any outcome, making them unfalsifiable.38 "All swans are white" is a scientific statement because it can be falsified by the discovery of a single black swan. In contrast, the claim "An invisible spirit influences our lives" is generally unscientific. Whatever happens, or doesn't happen, can be attributed to the spirit, leaving no clear way to prove the claim wrong.38
How can the vague claim "Ghosts exist" be transformed into a testable, and therefore scientific, hypothesis?
This claim is now testable. If the experiment is conducted under the specified conditions and no signal is detected, the hypothesis is falsified.39 Science advances through this process of systematically eliminating incorrect ideas. The fundamental problem with supernatural claims is that they are rarely presented in such a falsifiable form. And the moment they are, they confront the overwhelming counter-evidence discussed in Parts 2 and 3.
Let's address the user's final question about the possibility of an undiscovered element being a ghost particle. In short, the probability is virtually zero.
The 'Island of Stability' is a theoretical concept in nuclear physics that predicts that superheavy elements with specific combinations of protons and neutrons may have much longer half-lives than surrounding elements.42 However, 'long' here is a relative term. Even the most optimistic predictions estimate the half-lives of these elements to be on the order of minutes, days, or at most, a few years—they do not assume eternal existence.44 The half-life of the heaviest element synthesized to date, Oganesson (atomic number 118), is less than a millisecond (0.001 seconds).42
More importantly, their physical properties are key. If an undiscovered element were to exist, it would still be an 'atom' composed of a heavy nucleus of protons and neutrons, with electrons orbiting it. It would be incredibly dense, emit intense radiation, and interact very strongly with surrounding matter via the electromagnetic and strong forces. This is the exact opposite of the properties of a ghost, which is described as non-material and non-interactive, passing through matter. Therefore, the probability that a ghost is made of an undiscovered element is physically impossible.42
To conclude, this report synthesizes the analysis to provide a final, clear comparison of atoms and ghosts as objects of human knowledge, reaffirming the power of the scientific method.
Both atoms and ghosts exist beyond our direct senses, but they belong to fundamentally different epistemological categories.
The Atom is a concept whose reality has been verified through a rigorous, public, self-correcting, and predictive methodology: science. We do not feel atoms directly, but we are confident in their existence through their consistent and measurable effects on the world.
The Ghost is a concept rooted in subjective, private, and unfalsifiable personal experience. Its reality is asserted based on an individual's perception, but the perceptual experience itself is sufficiently explainable by the known internal functions of the brain.
In conclusion, the fact that we cannot 'feel' an atom is a matter of 'scale,' but its existence is clearly proven indirectly. In contrast, the ghost phenomenon is characterized by a 'lack of proof,' and the experience aligns with scientifically explainable brain phenomena. To place these two on the same level is to confuse fundamentally different types of evidence and modes of argumentation.
This report concludes not by dismissing the user's questions, but by valuing them as a precious attempt to expand the boundaries of knowledge. Asking such fundamental questions is the essence of intellectual inquiry.
The final conclusion is that while science cannot disprove the subjective experience of 'seeing a ghost,' it provides an overwhelmingly powerful and coherent framework that explains our physical universe and mental phenomena without needing to invoke external entities like 'ghost particles.' In navigating the complex territory between what is physically real and what is subjectively perceived, the scientific method remains the most reliable tool humanity possesses.
