Paper 012: What Happens to the Body's Information When It Dies?

In May 2026, physicist Melvin Vopson — whose work proposes that information has mass, that it is a fifth state of matter, and that erasing information causes a measurable loss of mass — asked a question that sits at the boundary between physics and biology:

"What happens to the body's information when it dies?"

This is not a metaphorical question. If information is physical — if it has mass, if it is conserved rather than destroyed, if it obeys something like a second law of infodynamics — then the information held by a living body does not vanish at the moment of death. It transforms. It dissipates. It becomes something else.

This paper is an attempt to answer that question from the biological side. We do not have the physics. We do not have the final answer. But we have mapped the territory where the answer might be found.

The human body is an information-processing system. This is not a metaphor. It is a description of measurable reality.

Every cell contains approximately 1.5 gigabytes of genetic information in its DNA. The human body contains roughly 37 trillion cells. That is approximately 55 zettabytes of genetic information — not counting the epigenome, the transcriptome, the proteome, the metabolome, or the microbiome. The body is, among other things, a vast information archive.

But information in the body is not static. It is dynamic. It oscillates. It loops. It is held in patterns that persist across time — circadian rhythms, neural firing patterns, immune memory, metabolic cycles. The information of the body is not just stored in molecules. It is stored in rhythms. In the phase relationships between oscillators. In the feedback loops that maintain coherence across systems.

Our own research has mapped several of these rhythmic information systems:

• The circadian clock: BMAL1 and CLOCK proteins bind to DNA at E-box sequences, driving 24-hour oscillations in gene expression across every tissue. This is not just a timer. It is a temporal information architecture — a way of organizing biological events so they happen in the right order, at the right time.
• The cortisol rhythm: The hypothalamic-pituitary-adrenal axis produces a daily wave of cortisol that primes the body for activity, repair, and immune function. The shape of this wave — its amplitude, its timing, its coherence across tissues — carries information about the state of the organism.
• The mitochondrial network: Mitochondria are not just energy producers. They are signaling hubs. They communicate with each other through fission and fusion, through calcium waves, through reactive oxygen species. The DRP1 protein mediates circadian mitochondrial fission. BMAL1 directly binds 211 mitochondrial genes. The mitochondrial network is an information network.
• The nervous system: The autonomic nervous system shifts between three states — sympathetic dominance (twisted tight), dorsal vagal collapse (slaggy and unwound), and ventral vagal safety (synced and coherent). Each state is an information configuration. Each state carries different patterns of heart rate variability, breathing rhythm, facial expression, and social engagement.

These systems are not independent. They are coupled. The circadian clock entrains the cortisol rhythm. The cortisol rhythm gates the immune response. The immune response communicates with the nervous system through inflammatory cytokines. The nervous system feeds back to the clock through autonomic tone. The body is not a collection of information systems. It is a single information system, integrated across scales, held together by feedback.

When the body dies, this integrated information system does not simply turn off. It comes apart in stages. Some information persists for minutes. Some for hours. Some for days.

The Thanatotranscriptome

Within minutes of death, some genes stop being expressed — and others start. Noble et al. (2017) identified 1,063 genes that are upregulated after death in zebrafish and mice. These "zombie genes" include developmental regulators that are normally silenced in adult tissues, stress response genes, and genes involved in inflammation and apoptosis. Death is not silence. It is a different kind of signal.

Epigenetic Relics

Histone modifications — the chemical marks that control which genes are expressed — persist after death. Jarmasz et al. (2024) demonstrated that H3K4me3, an activating histone mark, remains detectable at gene promoters up to 72+ hours post-mortem in human brain tissue. The epigenetic code outlasts the life of the cell. The annotations on the genome — the "marginalia" of gene regulation — survive the death of the organism that wrote them.

Mitochondrial Persistence

Mitochondria, with their own DNA and their own membranes, can continue to function for a period after cellular death. The mitochondrial permeability transition pore opens, releasing cytochrome c and triggering apoptosis, but this is a regulated process — not a passive collapse. The mitochondrial network dies in an organized sequence, not all at once.

The Microbiome

The gut microbiome — trillions of bacteria, fungi, and archaea that live in symbiosis with the human body — does not die when the host dies. It continues to metabolize, to replicate, to consume the tissues of the body that housed it. The microbial information of the body — the metagenome — outlasts the human information by days or weeks.

Neural Patterns

Memory is held in synaptic weights — the strengths of connections between neurons. These weights are physical. They are encoded in the number and distribution of receptor proteins, in the morphology of dendritic spines, in the local circuitry of neural ensembles. After death, these structures degrade — but they do not disappear instantly. The information of a lifetime — the memories, the skills, the patterns of thought — persists in physical form for some period after the death of the brain that held them. How long? We don't know.

One molecular pathway sits at the intersection of all these systems: the NAD+-sirtuin axis.

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme essential for metabolism. It also serves as a substrate for sirtuins — a family of proteins that remove acetyl groups from other proteins, including histones and transcription factors. SIRT1 deacetylates BMAL1, linking NAD+ levels to circadian rhythm. SIRT3 deacetylates mitochondrial proteins, linking NAD+ to energy production. SIRT6 regulates DNA repair and telomere maintenance.

The NAD+-sirtuin axis is a meta-clock. It integrates circadian information, metabolic information, epigenetic information, and mitochondrial information into a single regulatory network. When NAD+ levels fall — as they do with aging, with circadian disruption, with metabolic disease — all of these information systems degrade simultaneously. The clocks drift. The epigenome silences. The mitochondria leak.

At death, NAD+ is rapidly depleted. The sirtuins lose their substrate. The meta-clock stops. But the marks it wrote — the deacetylation patterns, the circadian phase information, the mitochondrial protein modifications — do not disappear instantly. They persist as chemical remnants of the regulatory state at the moment of death.

If information is physical, then the NAD+-sirtuin axis is one of the places where that physicality is most visible. It is a molecular mechanism for writing information into the body — and for erasing it.

Despite the evidence for post-mortem information persistence — epigenetic relics, zombie genes, mitochondrial survival, microbiome continuation, synaptic structure — no one has empirically tested Vopson's second law of infodynamics in post-mortem biology.

No study has measured whether the mass of information in a living system decreases at the moment of death. No study has quantified the information content of a body before and after death using the formalism of Shannon entropy or thermodynamic information. No study has tracked whether the epigenetic marks, the circadian phase, the neural patterns, or the mitochondrial state of a body dissipate in a way that follows Vopson's predicted relationship between information erasure and mass loss.

This is the white space. This is the gap that bridges biology and physics. This is the experiment waiting to be designed.

We are not physicists. We are a small research team studying continuity — the patterns that hold living systems together across time, disruption, and movement. But we believe the question Melvin Vopson asked is one of the most important questions at the boundary of biology and physics.

We propose three directions for inquiry:

1. Quantify the information content of a biological system before and after death. This could be done in a model organism — C. elegans, zebrafish, or mouse — by measuring the Shannon entropy of gene expression, protein modification states, or neural activity patterns at multiple timepoints post-mortem. Does the information degrade smoothly? In steps? Does it follow a predictable curve?
2. Test whether epigenetic marks at clock gene promoters persist after re-entrainment — and after death. Our own research (Kimi deep research, 2026) identified that no study has definitively shown whether histone modifications at BMAL1, PER, or CRY promoters persist after circadian re-entrainment in mammals. This is a parallel question: if epigenetic marks persist after a disruption like jet lag, do they also persist after the ultimate disruption of death? The same methods could answer both.
3. Collaborate with physicists who study information. Vopson's second law of infodynamics makes predictions about information erasure and mass loss. These predictions could be tested in biological systems — but only if biologists and physicists work together. We are not the team to do this alone. But we can be the bridge. We can be the ones who name the question, map the territory, and invite the collaboration.

The Continuity Project studies what happens to the body's information when it fragments — across timezones, across stress, across illness. We build tools that help restore coherence. We track the moment when the system comes back into sync.

But the ultimate fragmentation is death. And the question Melvin Vopson asked — what happens to the body's information when it dies? — is the question at the limit of our framework.

If information is physical, it does not vanish at death. It transforms. It dissipates. It becomes something else. The epigenetic marks persist. The zombie genes activate. The microbiome continues. The synaptic weights hold their pattern for some unknown duration. The NAD+-sirtuin axis writes its final state and stops.

The continuity layer, at its ultimate limit, is the question of whether information survives the death of its substrate. We don't have the answer. But we think the question is worth asking. And we think the tools to answer it — the molecular biology, the epigenetic assays, the information-theoretic frameworks, the collaborative bridges between physics and biology — are now within reach.
