What's Real About Time? | Episode 510 | Closer To Truth 

The cheapest way of time travel is taking a nap, you close your eyes and leap into the future.

Lee Smolin was by far my favorite interviewed expert in this episode... thank you.

Lawrence you are in my head. All of your videos have plagued me all of my 45 yrs. Thank you for sharing your journey with us like minded people. But it is all consciousness, there is no thing else.

This podcast is truly outstanding. I so appreciate professor Kuhn's intelligent explorations of the thinking of the best minds.

Best channel on you tube 🙏🙏

One of my favourite channel on RU-vid!

Its Such s treat being able to listen to these conversations.

I'm not a mathematician, so that language is beyond my scope, but having listened to many physicists explain time and space in their own terms, Lee Smolin makes the most sense to me. He doesn't have a final answer, but his explanations comport with my own uneducated view of space and time. It's comforting to know that there's someone out there in the field who is respected and who has come to see that my view of the world is quite possible from a scientific perspective. If you'd been laughed at as many times as I have by physicists or had gotten those glaring stares as much as I have, that means something.

Knowledge and understanding is the most precious gift. Mr. Khun’s contribution in bringing us all Closer To Truth is invaluable; respect, kudos and sincere appreciation to him as we continue to follow him on our journey of discovery. This respect comes all the way from Hong Kong 🙏🏼.

Very beautiful videos thanks .... worth millions and millions of love

"what do you feel?".... You can see the real enthusiasm and struggle on Robert.

I'm not sure if this show is taking me closer to truth or closer to head explosion but i love every episode. Thanks!

BTW - Kip Thorne’s articulation of relativity was masterful in its simplicity and clarity.

We need to understand what time isn't, so we can narrow down what time could be!

Thanks for these videos. I'm not a Scientist. I'm just a regular person with many questions and a thirst for answers. Your quest to find answers to my difficult questions is commendable.

One of my best episode, thanks !

One of the best episodes. Congrats Robert! I would have asked the very same question about the existence of the future in block universe... 😊

There is no real time outside without human awareness.

All it takes is one curious human being.Dear author thank you for genuinely being curious and putting out all the knowledge to the world.

Pleasure overload.

The way the audio repeated at 8:46 as they were talking about how crazy time was...had me thinking I entered a time loop

It takes time to get closer to truth

Fantastic as usual

love this show for along time BTW. im pausing it and going over it again and looking up definitions.

I really wish Robert Lawrence Kuhn would interview me on these topics. I have ALL the answers!

Loving this channel.

Physics and philosophy seems so the same at that level. They can say whatever they want and everybody will listen in awe.

I don't have the words to express how I love that show. I need more of that great thinking presented here. Thanks, happy Christmas to all of you.

What Robert is doing is truly amazing. Seeking the truth in the mix of solid science and biased beliefs. There is no consensus on time no matter how successful are theories backed by empirical evidence. And to put ot simply thete is no time only abstract clocks conveniently located wherever we need them. But scientist don't like the mystery to disappear so they keep supporting mythologies.

Thank you! I can sense my conceptual horizon expanding as I watch your videos. (The word gravity leapt to my mind a few minutes before one of your interviewees brought it up.)

Beautiful!

I really enjoyed this one.

I just love kip Thorne. Genius mind

I have the feeling that I am always "here" and always "there". I could take you to the exact location of my 5th Birthday and I think I am still there in time in the everlasting "now". All time exists in an eternal now.

Great episode.

I sometimes look at books that I have read, or even stacks of books, and think, "All of that is in my head."

I think time being emergent is a very simple and coherent theory, and it ties well with the simplest theory of personal identity. We feel as if time exists, and that is because we remember our past but not our future, and we can differentiate between 1 second ago and 5 seconds ago, that is just the way our brains evolved. There is a certain order in which our mental states occur, from past to future. There is no reason for this order, or for time to be fundamental. It is a useless ontological commitment. We experience things in a certain order, which alligns with classical laws of physics for a simple reason that those classical laws were developed by information processing system which works in time. So you measure ball's velocity at t=1, then t=2, then t=3 and so on. You don't measure it at t=3 and then at t=1 and then at t=2 and then try to develop a set of equations that would support such evolution in such time, it is not evolutionary benefitial at all for us to have such method as even somehow intuitive. Imagine knowing just all the states of the ball without knowing the time, you can try developing laws of physics for each possible ball-state combination, and you will likely find that the simplest ruleset is the one that describes the evolution of ball-states in the same time we experience. This is because our brain is an object, just like the ball, and all the information processing in it is more likely to occur by the simplest ruleset which is the one that matches with the order in which we experience things. Here is my argument: I can imagine such a bundle of ball-states that the simplest ruleset explains a certain succession of those given ball-states does not match with the simplest ruleset that explains the succession of states of the information processing system that is studying the ball's movement. Time is the order in which information is processed. There is nothing fundamental about that order. It just happens to allign well with everything else happening in the physical world, for reasons described above. It could be that it does not allign, although I am sure it is mathematically very unlikely. So the picture that follows from this: there is a bundle of mental states. Those are experienced in a certain succession, each of them feels like it occured after the previous one. This succession is emergent. I actually have a very simple argument for that order being emergent. Let's suppose it's fundamental. If order is fundamental, t1 t2 t3 is different from t3 t2 t1. Let's say t1 is experiencing rock flying into the window, t2 - rock breaking the window, t3 - aftermath. t3 feels like continuation of t2 and t1, because it contains memory about those. If you reorder the mental states so that t3 is the first, t3 still contains the memory of t2 and t1, it still feels continuous with t2 and t1. And t1 does not become such that it contains the feeling of being continuous with t3. Reordering the mental states did nothing, as the contents of those mental states didn't change. The subject of the subjective experience realized in those mental states will experience the same thing regardless of the "order" of his mental states. Given that, there is no reason for an ontological commitment to the existence of any specific order as it does not make any difference.

kuhn's face when the guy says 'two axis of tome', so good. same here :-)

Time is natures way of preventing everything from happening at once.

I think time is as real as temperature is. Nobody talks about if temperature is "real".

Really good!

The way some of these guys, like that Nima dude, will just rattle of facts and figures related to concepts and principles like Plank length in a "of course everybody knows that," sort of manner always blows my mind. It's not done in a I'm the smartest guy in the room kind of way, it's just how they roll. His stream of consciousness is vastly different from mine that's for sure.

Beautiful work as always 👏 Boy, I wish we knew the truth about time, it's the topic that intrigues me the most

Great episode. All that in 26:46!

Pure mental bliss

Space creates time!

when i was very young maybe 6 years old and i was told to wait 5 minutes or 10 minutes for something i would look at the clock and man it really felt like forever. and people would say thats because your young time will go faster as you get older implying that its a figment of the imagination. But as i am learning these things i realize now that it was not a figment of my imagination time really was going so slow for me and that it most likely has something to do with my size that i was was much smaller in relation to the earth then adults. and then it all made sense. on a side note its nice to know we have all lived a life time no matter how fast we die. and imagine how long time is for a microscopic organism. when i was real young it felt like the time would never come that i die but we know that it will come. so all that matters is what lays ahead and what is out there in space and beyond our dimensions even. when you think about why anything at all rather then nothing at least for me i am understanding that its because it had to be and most likely everything had to be and there is no such thing as nothing.. in fact that is the meaning of nothing, that it don't exist. so don't worry you are here and will always be here.

That's such an interesting and damn good question

Time--The absolute unit

Phenomenal

Two axes of Time... that's my mind blown for a week or two!

All I can say, it's about TIME ~ !

That was such an intense episode but so good 👍

It is real that time is a concept of the rate of motion intrinsically from each heart and mind.

Every one feels time no one knows time.

I would postulate that time is emergent from space and that no space is impossible (a vacuum is still a space with feilds.). Our brightest minds are experts at rationalising, analysing and justifying any point in or about our Universe.

Time is a loop, Perfectly spiraling out and back in to itself.

I am a simply a devotee of your curiosity and lucidity.

Thanks

It's common misunderstanding that it is possible to go back and forth in space. Matter defines spacetime and when you are moving forward then the space behind you is not the same space - there the defining matter has been changed - you can never go back to the past position but when you imagine you turned back, you only turned the direction where was the next forward direction. Space and time are really equal.

Got lost in there but since my brain organises my life around space, time and cups of tea, I managed to find a way out of the maze and survive and i feel ok again...😉🤔🤕

Makes my mind wander and even believe i can solve time travel 🧳🧭 😂😂 love it

what lee smolin said was very interesting

I like the way the first guy describes time, he's getting closer to the truth. A time traveller would be able to master skills at seemingly superhuman speeds wouldn't they. because they could simply spend hours practicing and then return to the point in time where they started learning and look like a genius. If someone could manipulate time that would make them invincible next to those that couldn't. They would know things they shouldn't know. They could have entered a room heard a conversation, then gone back in time and never entered that room and still known what was said leaving the occupants wondering are they guessing? they couldn't possibly know that could they? Think about it, I wouldn't mess with a time traveller, neither should you.

Real about time is both the potential time + the realized time.

I can't wait until he writes a book with all the knowledge he's been collecting

So time is conciousness

It’s always amazing that so many smart people presupposes that it’s time that’s the illusion and not our perception. Having different perceptions of time doesn’t equal no Simultaneity. The firecracker appearing to fire differently to the observer tells us nothing about the true nature or the reality of time.

Time is contingent on individual perception. Blows your mind to try and conceive it.

Nothing but the intervals to which we attach names: hour, minute, second. Einstein demonstrated in 1905 that time does not exist, its only valid expression is as a variable.

4:18 Strong parallels with children or grandchildren. As a parent, you are constantly sending information backwards in time in a sense to avert disasters but never being able to realize that world for yourself. You try to give them hints and advice earlier in their youth than you understood that information in yours. Their reality is a split dimension of what yours could have been.

I'd love some new episodes if that were possible once this pandemic is over come on Robert you can do it

Wow Lee Smolin just dropping a truth bomb over there

When you interviewed Kip Thorne, you should have asked him about his fine collection of vintage CRTs.

I believe time fits better as an emergent dimension, not a fundamental one

Time is just the freedom to move

Intresting topic just the other day I said time can be manipulated I hear you !

Since the space and time are relatives and everything exists in spacetime can be reduced to information that is perceivable only by consciousness thus fundamental quantities must be consciousness and information("knowledge").

Time is measured causality.

Closing was closer to truth

Whats real about time is that I never seem to have enough time.

It passes!

Listening to the different views of the last two physicists - from my lay perspective - seemed like the Pre-Socratic philosophers Parmenides and Heraclitus all over again.

I feel same Sir🇮🇳 time is illusion Sir🇮🇳

When were these shows produced?

What in the world am I missing here? Isn't it obvious to everyone that time is a human construct to organize our lives and that it doesn't actually exist whatsoever in the universe. Time is just simply reality playing itself out in the moment where existence lives. These people are batshit crazy.

Time is the center of infinity

There is no time...only now....our identity is a constant always present in the now...so its a I AM...think about a "past"event and you relive it as though you are experiencing it...same with "future"...I want this type car is only because youve experienced the feeling of owning it as NOW..thats how we get goals...in.my practice I helped most people to stop reliving past experiences..im a clinical.psychologist....ive not had a watch or clock for over 30 years and ive never been late...stop thinking time and your internal watcher keeps you always "on time"....we only move through events..seasons...but ALWAYS as me now...the eternal I AM

Time is as real as the human mind can make it

Events may come and go, they may emerge , be simple or complex, be reducible to something fundamental.time cannot.

What's real about time? I'll tell you in a moment...

Could be that time is actively shaping physical reality. When perceive time, perceive different effects on physical reality that time is shaping.

Is e=mc^2 exact, or is it an approximation, like the fine structure constant?

Time is existence.

The last guy has the most reasonable position

Great work. Here we have a place where people share their reasoning and ideas about time. Or spacetime as an entity. Suppose someone nailed what spacetime really is. Ultimately if a God is at play here we have fast and seemingly unusable stuff that is transformed like magic into stable building blocks. Once you get used to the idea of interdimensional sparks traversing the quantum world you become a timeless shapeshifter by nature and retain a real connection to energies available to you.

I think time is just a collection of single moments. Nowadays I can continuously take fast snapshots with my phone as I'm moving. If i were to take all of those images into my movie editing software and make each frame as short as possible, i could almost create the illusion that it's a video and not a collection of images. Maybe the Universe is expanding into time itself, rather than both time & space on the run into an endless void. That would mean, what happens in 10 years from now is already predetermined, it will happen, because space will catch up to that moment of time. The smallest measurement of time is Planck length, but that's only because we can physically measure it. Any measurement of time within space is possible, without space, it's immeasurable. Impossible isn't the word, you can't exactly measure infinity.

Watch your back

Could there be causation at the planck space / length, which also produces the future beneath the planck time? What might causation look like physically?

May you have an UNEVENTFUL NIGHT
