Imagine a transparent cube. Inside it is an ordinary city intersection. People cross the road, cars drive past, someone in a red coat strides across the crosswalk. But if you rotate this cube, the picture changes. The figures stretch out into long, strangely curved trails. A person is no longer walking — they become a continuous ribbon that begins at one end of the cube and ends at the other. Their entire trajectory over several seconds exists all at once.
It is precisely videos like these that have spread rapidly across the internet in recent days. One of the most striking is a piece by Bradley Tangonan. In the transparent volume you can see passersby turning into thin, winding threads. Another video shows aquarium fish: their movements fold into golden spirals that stretch through the entire space of the cube. Here time ceases to be an arrow. It becomes a direction, as real as length, width and height.
Physics has long described the world in exactly this way. In Einstein's special theory of relativity, space and time form a single four-dimensional continuum — spacetime. Events do not "happen" and do not disappear. They simply exist at different points of this continuum. The life of each of us is a world line: a continuous curve that begins at the moment of birth and ends at the moment of death. From the point of view of four dimensions, you are already "drawn" in your entirety — from the first cry to the last breath.
This idea is known as the block universe, or eternalism. The past, the present and the future exist equally. What we call "now" is merely a slice that our consciousness snatches from the whole. Einstein once remarked that the distinction between the past, the present and the future is nothing more than a stubbornly persistent illusion. Visualizations like the ones now circulating online make this thought almost tangible.
Interestingly, such techniques did not appear yesterday. Back in 2012, researchers Cuong Nguyen, Yuzhen Niu and Feng Liu presented "Video Summagator" — an interface that turned video into a three-dimensional cube in which time becomes the third axis. Even earlier there were slit-scan methods and experiments with "volumetric cinema." Modern videos have simply made these ideas brighter and more accessible, using ordinary video recordings and contemporary visualization tools.
When you look at such a picture, a strange feeling of recognition arises. As if the brain momentarily steps outside the familiar flow. We are used to experiencing life frame by frame. But here the entire reel unfolds all at once. Every step, every sway, every turn of the head is already "recorded" in the structure of the cube. And at the same time the cube can be rotated, examined from different angles, "sliced" and peered into.
Of course, this is only a projection. Real four-dimensional spacetime cannot be seen directly — our brain and our eyes are built for three dimensions. But even such a shadow allows us to sense the scale. If everything already "is," then what does movement mean? Why do we feel the flow of time? These questions remain open. Physics provides a mathematical description, while consciousness stubbornly continues to experience life as a story that is still being written.
The videos keep spreading, provoking the most varied reactions — from admiration to slight dizziness. Some see in them a confirmation of the theory of relativity, others a hint of something greater. Either way, they do one important thing: they make us stop and look at the familiar world differently. For a moment, the familiar flow of time turns into a motionless yet infinitely complex volume in which we are all already present in our entirety.
