I can say that my GPS “thinks” I took a wrong turn without really committing myself to my GPS being a conscious, thinking being. My GPS has no mind, and thus no mental map of the world, yet I am not wrong in understanding its output as a valid representation of my location and my destination.

Similarly, even though physics leaves no room for the dynamic passage of time, time is effectively dynamic to me as far as my experience of the world is concerned.

The passage of time is inextricably bound up with how humans represent our own experiences. Our picture of the world is inseparable from the conditions under which we, as perceivers and thinkers, experience and understand the world. Any description of reality we come up with will unavoidably be infused with our perspective. The error lies in confusing our perspective on reality with reality itself.

Similarly, my research suggests that the passage of time is neither real nor an illusion: It’s a projection based on how people make sense of the world. I can’t really describe the world without the passage of time any more than I can describe my visual experience of the world without referencing the color of objects.

Time as a psychological projection

One common option has been to suggest that the passage of time is an “illusion” – exactly as Einstein famously described it at one point.

Calling the passage of time “illusory” misleadingly suggests that our belief in the passage of time is a result of misperception, as though it were some sort of optical illusion. But I think it’s more accurate to think of this belief as resulting from misconception.

Change just means that the situation is different at different times. At any moment, I remember certain things. At later moments, I remember more. That’s all there is to the passage of time. This doctrine, widely accepted today among both physicists and philosophers, is known as “eternalism”.

This brings us to a pivotal question: If there is no such thing as the passage of time, why does everyone seem to think that there is?

Under relativity, all times are equally real. Everything that has ever happened or ever will happen is happening now for a hypothetical observer. There are no events that are either merely potential or a mere memory. There is no single, absolute, universal present, and thus there is no flow of time as events supposedly “become” present.

How much time elapses between events, and what time something happens, depends on the observer’s frame of reference. Observers moving relative to each other will, at any given moment, disagree on what events are happening now; events that are happening now according to one observer’s reckoning at any given moment will lie in the future for another observer, and so on.

This notion affects our understanding of what clocks actually do. Because the speed of light is a constant, two observers moving relative to each other will assign different times to different events.

In a famous example, two equidistant lightning strikes occur simultaneously for an observer at a train station who can see both at once. An observer on the train, moving toward one lightning strike and away from the other, will assign different times to the strikes.

Someone floating in space sees a spaceship going by to the right. But the universe itself is completely neutral on whether the observer is at rest and the ship is moving to the right, or if the ship is at rest with the observer moving to the left.

To take this fact seriously, he argued, is to take all object velocities to be relative.
Nothing is ever really at rest or really in motion; it all depends on your “frame of reference.” A frame of reference determines the spatial and temporal coordinates a given observer will assign to objects and events, on the assumption that he or she is at rest relative to everything else.

이거저거 곁가지들 다 쳐내고 LLM의 프로그래머 대체에 대해서만 이야기해보자면, LLM 기반 툴들은 디테일로 들어가면 약해지는 부분이 있어서 그런 부분은 사람이 잡아야 하니 아직까진 “완전 대체”는 불가능하다는게 내 평가임. 다만 사람이 하는 반복작업을 줄여주는 측면이 있어서 일자리 자체가 줄어드는 상황은 실제 발생하고 있음. 이후 AGI가 실제로 만들어지더라도 (물론 더 큰 폭으로 대체가 되겠지만) 이때도 프로젝트를 고민할 수 있는 시니어는 필요할거라고 생각함. 결국 책임을 질 누군가는 항상 필요할거라고 본다.

Then, Albert Einstein came along.

In 1905 and 1915, Einstein proposed his special and general theories of relativity, respectively. These theories validated all those long-running suspicions about the very concept of time and change.

Relativity rejects Newton’s notion about time as a universal physical phenomenon.

By Einstein’s era, researchers had shown that the speed of light is a constant, regardless of the velocity of the source.

Ancient philosophers on time

Ancient philosophers were very suspicious about the whole idea of time and change. Parmenides of Elea was a Greek philosopher of the sixth to fifth centuries BCE. Parmenides wondered, if the future is not yet and the past is not anymore, how could events pass from future to present to past?

Human beings have been thinking about time for as long as we have records of humans thinking about anything at all. The concept of time inescapably permeates every single thought you have about yourself and the world around you. That’s why, as a philosopher, philosophical and scientific developments in our understanding of time have always seemed especially important to me.

But go ahead and try to actually verbalize just what is meant by the flow or passage of time. A flow of what? Rivers flow because water is in motion. What does it mean to say that time flows?

Events are more like happenings than things, yet we talk as though they have ever-changing locations in the future, present or past. But if some events are future, and moving toward you, and some past, moving away, then where are they? The future and past don’t seem to have any physical location.

What is time? Rather than something that ‘flows,’ a philosopher suggests time is a psychological projection

by Adrian Bardon, Professor of Philosophy at Wake Forest University

“Time flies,” “time waits for no one,” “as time goes on”: The way we speak about time tends to strongly imply that the passage of time is some sort of real process that happens out there in the world. We inhabit the present moment and move through time, even as events come and go, fading into the past.

A Brief History of Time by Stephen Hawking, 2011

A landmark volume in science writing by one of the great minds of our time, Stephen Hawking's book explores such profound questions as: How did the universe begin--and what made its start possible? Does time always flow forward? Is the universe unending--or are there boundaries? Are there other dimensions in space? What will happen when it all ends?




Told in language we all can understand, A Brief History of Time plunges into the exotic realms of black holes and quarks, of antimatter and "arrows of time," of the big bang and a bigger God--where the possibilities are wondrous and unexpected. With exciting images and profound imagination, Stephen Hawking brings us closer to the ultimate secrets at the very heart of creation.

“‘Time’ is the most used noun in the English language, yet we still don’t really understand it. Adam Frank tells the fascinating story of how humans have struggled to make sense of time, especially in the context of the universe around us. From prehistory to the Enlightenment, through Einstein and on to the multiverse, this is a rich and inspiring tour through some of the biggest ideas that have ever been thought.”

A Very Brief History of Eternity by Carlos Eire, 2010

What is eternity? Is it anything other than a purely abstract concept, totally unrelated to our lives? A mere hope? A frightfully uncertain horizon? Or is it a certainty, shared by priest and scientist alike, and an essential element in all human relations?

press.princeton.edu/books/pape




In A Very Brief History of Eternity, Carlos Eire, the historian and National Book Award–winning author of Waiting for Snow in Havana, has written a brilliant history of eternity in Western culture. Tracing the idea from ancient times to the present, Eire examines the rise and fall of five different conceptions of eternity, exploring how they developed and how they have helped shape individual and collective self-understanding.

A book about lived beliefs and their relationship to social and political realities, A Very Brief History of Eternity is also about unbelief, and the tangled and often rancorous relation between faith and reason. Its subject is the largest subject of all, one that has taxed minds great and small for centuries, and will forever be of human interest, intellectually, spiritually, and viscerally.

"El mar y yo"

Fue un día que bañada en los marullos,

De un mar mágico y sereno

Que escuché los murmullos de sus olas

Que insistían golpeándome sin freno

«Mucho tiempo llevamos esperándote

Corre ya sin demora a nuestra casa»

Y la voz que escuché se repetía

Cada ola que golpeaba, hipnotizaba

"Ven conmigo novia mía, es el día...

Ven conmigo novia mía, a nuestra casa.

Navegué el amplio mar que llevaba hasta
