I often wonder—what is time? Where is time?

When we think of time as a dimension, a question arises: if we can perceive and measure length, width, and height, why can’t we perceive time in the same way? We don’t experience it physically, yet we feel it through thought.

And yet, time is undeniable. We depend on it so much that we always carry a clock, tracking it constantly. We don’t do the same with physical dimensions; we measure them only when needed. If time and space are inseparably linked, then time is the unseen counterpart—easily overlooked because our senses are tuned to the physical world.

But perhaps we do perceive time—not with our bodies, but with something else within us. Our bodies experience space because they can move through it. What if we have a nonphysical part that moves through time? Could this explain why we sense time even though we cannot touch it?

We only perceive time while we are alive. Without life, time ceases to exist for us. This suggests that our nonphysical essence moves through time, just as our bodies move through space. If time is truly the fourth dimension, then our nonphysical self may be the entity that occupies it—free to roam in ways our physical form cannot.

We often say, “Time and tide wait for none,” but perhaps that applies only to the physical world. If our nonphysical self were independent of our body, could it move freely through time? Could time even reverse or pause for it? Instead of searching for higher dimensions outward, what if they exist inward—beyond physical perception?

I’m not a scientist, but I use science where it applies. Where it doesn’t, I seek other ways to understand. Some human experiences—such as seeing the future in a dream or moments of awareness beyond death—suggest that part of us might transcend time, jumping through it without being bound by its linear flow.

Time feels faster or slower depending on our perception. The more we accept something, the faster time seems to move. Could acceptability be the key to how our nonphysical self progresses through time?

What if time and space are inseparable in the same way our physical and nonphysical existence are intertwined? Just as time is undeniable despite being invisible, our nonphysical self may also be unseen yet real.
