Life

This article explores that hypothesis, delving into the length, compression, and meaning of life, in an attempt to answer one question: How long is our life, really?

The Shadow of Life: A Higher-Dimensional View

Imagine our three-dimensional world is just a shadow cast by a higher dimension, much like a 2D shadow is the projection of a 3D object. If this were true, then to an existence in the Fourth Dimension or beyond, a 74-year human life might span only a few minutes, or even a few seconds.

We watch a fly buzz on a windowpane; its struggle and end are momentary. For that higher-dimensional observer, how different are our birth, growth, and death? This relativity forces us to ask: Is the long life we perceive just a brief clip in the cosmos? Perhaps our busy struggles are nothing more than insignificant flashes when viewed on a grander scale.

Life's Compression: From 74 Years to a Few Hours

What would 74 years look like if we linearly compressed it into a narrative? If made into a film, it might only require 2 to 3 hours to tell the story. The first cry at birth, the first day of school, the first paycheck, wedding vows, the birth of a child, and the final retrospective look back—these moments would flash by in a quick montage, condensed into a few key frames.

If you distill it further, listing the milestones on a checklist might fill only a few pages. Like a resume, one or two sheets can summarize a lifetime of experience. The daily trivialities and emotional fluctuations are omitted, leaving only the cold, hard "milestones." It's sobering to realize that what we spend a lifetime pursuing can be so easily reduced.

The Concentrated Memory: The Review Before Death

Scientific studies suggest that in near-death experiences, the brain may "replay" a person’s life at an abnormal speed. This means 74 years of experience could potentially be reviewed in mere minutes. You might remember a childhood summer, the thrill of first love, a major success, but most details are blurred or forgotten.

If life is a movie, these few minutes are the "director’s cut" we edit ourselves. The question is: If your 74 years can only be compressed into those few minutes, which moments do you hope to keep? Do the forgotten parts—the mundane days, the silent tears—still count as part of your life? Perhaps it is precisely these overlooked instants that form the fabric of our true existence.

The Digital Life: Cold Quantification

Let's convert 74 years into numbers: Assuming an average lifespan of 74 years (including 18 leap years), that’s 27,393 days, 657,432 hours, or 2,366,755,200 seconds. These figures seem immense, yet they are surprisingly simple. Every breath, every heartbeat, from birth to death, can be precisely calculated.

However, these cold numbers cannot convey our joy and sorrow, our struggles and achievements. 2.36 billion seconds sounds long, but on the scale of the universe's 13.8 billion years, it is a negligible flash. A human life, quantified into a string of symbols, fails to carry the weight of our inner world.

Fading Memory: The Epitaph's Silhouette

When we leave this world, how will family and friends remember us? They won't commemorate us with 74 years of runtime, or even review our full picture in a few minutes. More often, our life is condensed into a few lines on a tombstone. For example: "John Doe, 1951-2025, A Loving Father, A Dedicated Teacher." A long 74 years, reduced to a simple summary.

This reduction is a stark reminder: we strive for a lifetime, only to leave behind a handful of words. Perhaps this is the truth of life—in the river of time, we are ultimately simplified, and eventually forgotten. Those moments we felt were so profound drift away with the wind.

The Relativity and Meaning of Life

If life truly is a compressed projection from a higher dimension, then our 74 years are not long. Like the fly’s minute, it is everything to the fly, but a moment to us. We rush through life, and looking back, you might ask yourself: "What did I actually accomplish?"

We cannot change the total number of seconds we are allotted, nor can we dictate how our memory is condensed by others. But perhaps, the value of life is not in its length, but in how we spend every day. 74 years, 2.36 billion seconds—these numbers are just the frame. What truly matters is the story we write within it. We may not be able to extend time, but we can make every second warmer, ensuring this brief life is more than just a cold projection.

These profound ideas are mysteries we may spend a lifetime pondering. Yet, surprisingly, they can be written down easily in a few thousand words. The long journey of 74 years, condensed into this short essay, does it not reflect a certain absurdity and truth about life? Perhaps, that is where our deepest reflection begins.
