The Memory of the Universe – What Remains When Everything Seems to Have Passed?

We live with the assumption that time erases everything. Memories fade, words lose their resonance, and gestures seem to disappear irretrievably into the past. But does impermanence really mean that something vanishes without a trace? Or do we confuse what has slipped beyond our perception and memory with what has actually ceased to exist?

This is where the central question of this article begins: What traces are left behind by everything that has happened, and in what sense can something remain preserved even when it is no longer accessible to human beings?

Modern science approaches this question by examining how experiences alter the brain, how information is processed within physical systems, and under what conditions it can be preserved. The Qur’an offers a different perspective: it describes a creation in which nothing escapes the comprehensive knowledge of God, and in which human actions, together with the traces they leave behind, are recorded.

A fundamental distinction must be made here: science investigates observable and measurable processes within nature. The Qur’anic perspective, by contrast, is rooted in revelation and faith and describes a theological reality. Both engage, in different ways, with questions of preservation and impermanence, but they must neither be equated nor treated as proof of one another.

The purpose, therefore, is not to derive divine recording from scientific findings, nor to explain religious statements through natural science. Rather, it is to explore how two distinct approaches to knowledge touch upon a shared human question: Does what we can no longer see, remember, or comprehend necessarily cease to exist?

1. The Scientific Perspective: Traces of the Past

Neuroscience shows that experiences can leave changes in the human brain. Through a process known as synaptic plasticity, neural connections are strengthened, weakened, or reorganised. Memories are therefore not immutable records, but dynamic processes that can change over the course of a person's life.

Not every experience remains consciously accessible. Nevertheless, forgetting a memory does not necessarily mean that an experience has left no trace whatsoever. Past events can continue to influence perceptions, behaviours, and emotional responses.

One might compare this to a still pond whose surface remains undisturbed for years. Only when a stone falls into the water are sediments stirred up from the bottom. What had remained hidden rises to the surface.

In this sense, the human body can be understood as a biological bearer of its own life history. It does not store experiences like a digital archive, but processes them through complex neural, hormonal, and physiological mechanisms.

Modern physics also investigates whether information can be lost within the universe. In quantum mechanics, the conservation of information is regarded as a fundamental principle. The question of whether information could be lost inside black holes has occupied theoretical physicists for decades.

The theoretical approaches that currently prevail suggest that quantum information is fundamentally preserved, even when its original form is no longer accessible to an external observer.

However, this does not allow us to conclude that every human memory or every individual action is permanently stored in the universe in a form that can be retrieved. The physical conservation of information and human memory are two different matters.

Science can therefore explain how certain forms of information are processed, transmitted, and preserved under particular conditions. However, these findings cannot establish anything about divine recording or the afterlife.

2. The Qur’anic Perspective: Nothing Escapes the Knowledge of God

The Qur’an approaches the question of memory and preservation from a different epistemological perspective. Its statements are not based on empirical investigations, but on revelation and faith in the all-encompassing knowledge of God.

In Surah Ya-Sin, it states:

“Indeed, it is We who bring the dead to life, and We record what they have sent ahead and the traces they have left behind. And We have accounted for everything in a clear register.” (Surah Ya-Sin 36:12)

What is particularly striking here is the connection between a person's actions and the traces they leave behind. The verse speaks not only of what a person has done themselves, but also of the effects of their actions.

An action does not necessarily end at the moment it takes place. It can influence other people, set developments in motion, and produce consequences that extend far beyond its original occurrence.

In Surah Al-Kahf, this comprehensive record is described even more explicitly:

“And the record will be placed, and you will see the criminals fearful of what is in it. They will say, ‘Woe to us! What is this record that leaves nothing, small or great, without recording it?’” (Surah Al-Kahf 18:49)

According to the Qur’anic understanding, no action escapes the knowledge of God. Even what may appear insignificant or unimportant from a human perspective remains part of this all-encompassing divine knowledge.

This idea is complemented by the description of the angels entrusted with recording human actions:

“When the two receivers receive, seated on the right and on the left, no word does a person utter except that an observer is ready beside them.” (Surah Qaf 50:17–18)

And in Surah Al-Infitar, it states:

“Indeed, appointed over you are guardians, noble scribes, who know whatever you do.” (Surah Al-Infitar 82:10–12)

This recording cannot be compared to technical data storage. It is part of a theological order in which human actions take place under divine witness.

3. The Body as a Witness: A Theological Concept

Particularly striking is the idea that, on the Day of Judgement, it will not be only the human being who bears witness, but also their own physical existence.

In Surah An-Nur, it states:

“On that Day, their tongues, their hands, and their feet will testify against them concerning what they used to do.” (Surah An-Nur 24:24)

In Surah Fussilat, this idea is developed further:

“They will say to their skins, ‘Why have you testified against us?’ They will reply, ‘Allah, who has made everything speak, has made us speak.’” (Surah Fussilat 41:21)

From a theological perspective, the body thus becomes a witness to one's own actions. What a person may have forgotten, suppressed, or denied will be brought to light on the Day of Judgement.

These statements should not be understood as a scientific description of biological bodily functions. They belong to the Qur’anic conception of the afterlife and describe a reality that lies beyond empirical verification.

4. Creation as an Object of Divine Knowledge

The Qur’anic concept of comprehensive recording is not limited to human beings. It extends to all of creation.

In Surah Al-An'am, it states:

“And not a leaf falls without Him knowing it. And there is no grain in the darknesses of the earth, nor anything moist or dry, that is not recorded in a clear Book.” (Surah Al-An'am 6:59)

Even the falling of a single leaf is presented as an expression of a reality that lies entirely within the knowledge of God.

In Surah At-Takwir, the moment when the records are revealed is described:

“And when the records are laid open ...” (Surah At-Takwir 81:10)

And Surah Al-Inshiqaq adds:

“As for the one who is given their record in their right hand, they will receive an easy reckoning.” (Surah Al-Inshiqaq 84:7–8)

Recording, therefore, is not associated exclusively with accountability and judgement. It is also connected with justice and mercy.

5. Two Levels of Knowledge – One Shared Question

At this point, science and theology do not meet through their methods of proof, but through a fundamental human question: What does it mean for something to have happened, and what traces does it leave behind?

Science investigates the observable mechanisms of nature. It explores neural changes, information processing, and the laws governing physical conservation. Its claims must be measured against empirical methods and verifiable findings.

The Qur’an, by contrast, opens up a metaphysical and theological perspective. It describes a creation in which nothing escapes the knowledge of God and in which human actions possess a significance that extends beyond what is immediately visible.

These two perspectives must therefore neither be equated nor played against one another. The conservation of quantum information does not prove divine recording. Likewise, the Qur’anic concept of comprehensive divine knowledge is not a scientific theory.

Perhaps the real connection lies instead in the question that both perspectives touch upon in their own way: Does what we can no longer perceive or remember therefore become meaningless?

Human beings forget, reinterpret their past, and sometimes lose access to their own experiences. Yet their actions can leave traces that extend beyond their personal memory.

Perhaps impermanence is not the same as meaninglessness. For even if human beings cannot preserve everything they experience, the question remains: what do they leave behind in the world through their very existence?
