The Physicist Who Says Time Doesn't Exist

In today's episode of Theories of Everything, Curt Jaimungal and Julian Barbour challenge conventional physics by exploring Barbour's revolutionary ideas on time as an emergent property of change, the universe's increasing order contrary to entropy, and the foundational nature of shape dynamics.

Two hours of my time to watch this video to find out those two hours never existed to begin with.
I just don't have the time for this.

[julianamachado]

First of all, thank you for the subtitle options. Other channels don't understand how hard it is for a deaf person to enjoy a video and have to read the text word by word with auto-generated subtitles. Thank you so much!

[aarongreenfield]

So I can tell my boss he doesn't know what the hell he's talking about when I show up late for work?

[modalities]

Grateful for this interview. After reading A. Korzybski’s Science and Sanity back in 2001, I began to suspect and eventually conclude that we created the abstraction of time.

As a non-scientist I approached it from how we commonly describe time (English) - A measurement system used to sequence events, compare durations, and quantify intervals between events. The physicist’s description is more precise and more abstract … as a dimension (space-time); a parameter in equations of motion; in special relativity time is relative; and in quantum mechanics, time is an external, classical parameter that is not quantized.

Instinctively, I’m with Julian Barbour … and Albert Korzybski when in 1933, he wrote that “When we confuse our words or concepts with the actual things they represent, we risk misunderstanding or oversimplifying the world.” In the context of this interview, I would extend that to include “the Universe.”

[aristotle_]

Aristotle did not treat time as an actual thing, but as a human measure of change.

[davelister]

my favourite saying for the definition of time is: time is what stops everything from happening at once.

[fuseteam]

I don't believe he's saying time doesn't exist, he's more saying "time is a abstraction of change" which it is. As we measure "time" by counting recurrent events. So are we measuring "time" or "change"?

I came across Julian's ideas in my own research when pursuing my own insights. I've been fascinated but keep coming across the same speeches and presentations. Thank you Curt - for getting the most out of this time with Julian

[AlterFunKtion]

I once took mushrooms as a 15 yr old and came out saying "Time is an illusion caused by the movement of objects in space". It was so profound to me at the time that i could realize that.

[rainbowsally]

Time never existed? Well, that comes as a bit of a shock. When did THAT happen???

[henkverhaeren]

Time does not exist, yet it is the most valuable thing I have, every second of my life that is gone will be gone forever

[Phn_tm]

I really appreciate Julian's caution and parsimony in defining his concepts. I think that's where much of his strength comes from. He seems very adept at clearing out the confusion of terms that has grown like mildew throughout other theories.

[Contang]

This really was an incredible interview Curt, huge thanks to you for giving Julian the platform and giving him such respectful space to talk.

[Xueqs]

fascinating. the way he dismantles the 2nd law is amazing and I have no problem ditching it to make discoveries. also the idea that consciousness is manufacturing observations

[brandonb]

You had me at Mach! That was a lovely discussion, thank you both.
Nice job on exposing alternative perspectives Curt, well done.✌🏼

[ms]

Thank you for this interesting "time." I'm autistic and am on my 57th trip around the sun, and since I was a child, I've considered time a useful tool, but without forgetting that it's a concept, a "wildcard" variable that allows us to better understand the world of which we are a part. Our perception is fine for what it has evolved to, but even our mathematics needs to advance to be able to answer such interesting questions we ask ourselves. I've never thought of time as something real. Our minds have a very particular and concrete way of perceiving reality, but we are a mechanism that interprets it and tries to understand it, but we must recognize our own limitations. It is possible to understand reality, but I've always said that to see better, we must close our eyes. Thank you, and peace these days.

[robertwurgaft]

Just as he was about to elaborate on Mach's Principal, I paused it. At that moment, an ad began to come up, the text was: "For a limited time only".
I was instantly catapulted into wormhole of time.
HELP ME!😂

[zipperpillow]

Lovely man with important insights and not a shred of institutional smugness. We need more like him.

[pastor-tom-sims]

Amazing interview with a deep and engaging, personable guest.

Barbour's understanding of time mirrors mine as an amateur Christian theologian/philosopher.

I do not have the intellectual bandwidth to agree or disagree, but I have the curiosity to be fascinated.

I love his interest in etymology and his ventures across the line of science into philosophy which has natural implications for theology.

"Peer into my present deliberations." - Great choice of words from you, Curt. I must insert that phrase into my repertoire.

[rodcameron]

I have said for years that I believe time is nothing more than our perception of the separation of two events. So, to see someone else with at least a close approximation of that idea is really cool.
I really enjoyed this talk. I think what I enjoyed mostly was the wonder and imagination. I dont often get to hear a physicist enjoy the possibilities in speculation coupled with philosophy.
Leaves me wondering how it took me so long to find this episode.
