A Journey of Reflection — The Nature of Cosmic Time

Could it be possible that one day is equal to one thousand years?

At first, this idea seems impossible.

A day is a day.

A year is a year.

Human experience tells us that time follows a fixed pattern.

But the Qur’an invites us to think beyond ordinary human perception.

Allah says:

“He arranges the matter from the heaven to the earth; then it ascends to Him in a Day, the measure of which is a thousand years of what you count.”
(Surah As-Sajdah 32:5)

This verse presents a profound reality:

A “day” in the scale of divine affairs is not necessarily the same as a day measured by human beings.

But how can this be understood?

Allah Himself tells us:

“Do they not reflect upon the Qur’an?”
(Qur’an 4:82)

The Qur’an repeatedly encourages deep reflection.

So perhaps within these verses there are signs that invite humanity to think about the nature of time, creation, and the universe.

Who Carries Out the Divine Command?

The verse mentions the movement of affairs between the heavens and the earth.

According to Islamic understanding, these commands are carried out by angels — a creation unlike human beings.

Angels are described in Islamic tradition as beings created from light.

This point becomes important when we think about the extraordinary speed associated with light itself.

The Mystery of the Speed of Light

You may have heard of one of the most fascinating constants in physics:

The speed of light.

Light travels at approximately:

299,792.458 kilometers per second.

This is one of the fastest speeds known in our universe.

The fastest human-made spacecraft so far are nowhere near this speed.

For example, NASA’s Parker Solar Probe has reached extraordinary velocities, but they remain only a small fraction of the speed of light.

To understand the greatness of this speed:

The circumference of Earth is approximately 40,000 kilometers.

At the speed of light, a journey around the Earth could theoretically happen several times within a single second.

This is the scale of cosmic speed.

Why Reference Frames Matter in Physics

When scientists calculate the speed of light, they do so according to precise physical conditions.

Measurements depend on what is called a:

Frame of reference.

In physics, an observer’s state of motion and the conditions around them matter.

For example, calculations involving light speed are considered within specific inertial reference frames, where:

• The motion is measured in a straight-line framework.
• External forces such as gravitational effects are accounted for.
• The observer’s reference frame is properly defined.

This is essential because motion in the universe is not simple.

Everything is moving.

Earth is moving.

The Moon is moving.

The entire solar system is moving.

Comparing Cosmic Distances and Time

The speed of light allows it to travel an enormous distance in a single day.

Light travels approximately:

25.9 billion kilometers in one day.

Now a fascinating question arises:

Could we compare this distance with the movement of the Moon?

The Moon constantly travels around Earth.

But calculating its motion requires careful consideration.

The Moon does not move in a perfect straight line.

It follows an orbit.

Earth itself is not stationary.

The Sun’s gravitational influence affects Earth’s movement.

Therefore, to compare the Moon’s movement with light, scientists would need to define an appropriate reference frame.

The Lunar Orbit and a Reflection on the Qur’anic Verse

If we imagine the Moon’s movement calculated under a simplified inertial reference frame — treating the Moon’s orbital movement as a comparable distance measurement — we arrive at an interesting reflection.

The Moon travels approximately:

2.15 million kilometers in one month.

Over twelve thousand lunar months — approximately one thousand lunar years — the accumulated distance becomes comparable to the distance that light travels in one day.

This mathematical relationship has led some people to reflect on the Qur’anic statement:

A day in the scale of divine affairs being equivalent to a thousand years of human counting.

The comparison is fascinating because it brings together:

• The movement of celestial bodies
• The measurement of time
• The speed of light
• The scale of the universe

A Deeper Question: Why Light?

The script raises an important philosophical question:

If angels are a creation associated with light, and if they carry out commands by Allah’s permission, could their movement occur at a scale beyond ordinary human experience?

Could the difference between cosmic time and human time reflect realities of existence that we cannot fully perceive?

These questions invite reflection.

However, the complete reality of angels, time, and the unseen belongs to the knowledge of Allah.

Human calculations can only explore signs within creation.

They cannot encompass the unseen world completely.

Another Qur’anic Mystery: Fifty Thousand Years

The Qur’an also mentions another remarkable measurement of time.

Allah says:

“The angels and the Spirit ascend to Him during a Day, the measure of which is fifty thousand years.”
(Surah Al-Ma‘arij 70:4)

Now another question appears:

If one place in the Qur’an mentions a day equivalent to one thousand years, and another mentions a day equivalent to fifty thousand years, how should we understand this?

What are the “levels” and realities being described?

What does Al-Ma‘arij — the pathways of ascent — mean?

This is another fascinating journey of reflection.

The Journey Continues

The universe is filled with signs that challenge human understanding.

Time, space, motion, and creation itself reveal that reality is far greater than what our senses alone can perceive.

The Qur’an does not merely ask us to look at the universe.

It asks us to think.

To reflect.

To seek deeper understanding.

Because the more we discover about creation, the more we realize the greatness of the Creator.

In the next episode, we will explore:

Why does the Qur’an mention a day equal to fifty thousand years?

What are the mysteries behind Al-Ma‘arij?

Until then,

Allah Hafiz.
