- Albert Einstein shattered previous ideas about time, but left many pivotal questions unanswered: Does time have a beginning? An end? Why does it move in only one direction? Is it real, or something our minds impose on reality? Journalist John Hockenberry leads a distinguished panel, including renowned physicist Sir Roger Penrose and prominent philosopher David Albert, as they explore the nature of time.
This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.
The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

Finally Sir Roger Penrose received the Nobel Prize. Congratulations!
@Leonhard Euler Thx
I’m literally spending my Friday night listening to this discussion. Me 10 years ago would have never hung out with me now.
You ten years ago wasnt good enough to hang out with you now lol
I feel that
Agreed!

nor would have me...looks pretty loolly ...ui....
We should throw away the word "time" and simply use "change' instead. In this way we can discuss variable rates of change in different places of the universe. Then we can see things like gravity as simply changes in the rates of change giving acceleration in the form of space/rate of change. Then you can ask questions like, 'well what is changing the rate of change?' If it is simply that more energy in a space means things become more complex and the universe responds by slowing down the rate of change then many things become explainable.
Brilliant response that I can't believe doesn't have more likes/consideration.
Yes!!! 👏🏼👏🏼👏🏼
It's change, and I probably should have gone to bed change ago, but surely there's still change for us to discuss appropriate verb forms, and the ontological utility of understanding time as simply "changeable rates of change", energetically changing.
I like this concept (whether it is correct or not) because it demonstrates a different way of thinking about time. To ask a question of this though is : what causes change? It's an aspect of the direction some thoughts I have regarding this.
As soon as you say “rate of change” surely you introduce the concept of time
Looooove these panel discussions, especially with the artistic interludes. The cosmos, quantum everything is inspirational to so many.
Great to see Michał Heller in such a panel, I really enjoyed his books
The discussion by David Albert at 39:20 is worth watching a couple times. The "arrow of time' or 'flow of time' is a metaphor.
Doug Edmunds A metaphor is supposed to bring or displace an abstract concept in a more tangible form. This is not a metaphore.
Whether or not metaphor is the right way to describe what is he was saying about "flow/arrow of time", that part of the discussion is worth watching a couple of times.
Although I do agree with @Dani that this is not a metaphor. He was not claiming that it was a metaphor. He claiming that we had no rational framework for conceptualizing "flow of time" with or without relativity.
Ticking away...the moments that make up a dull day.
(add the next line)
Currently, I'm convinced that changes in time result from changes in energy, and energy is more fundamental than time. Without a change in energy, there's no change in time.
Great debate, I thoroughly enjoyed it.
Great Debate indeed, but why is Sean Caroll not mentioned in the description of participants?
Woo! Penrose!
love this kind of content , just don,t like being interrupted by adds although this one seems free of it, but thanks TH-cam.
These kind of videos make me feel like I should write my.own theories about time and movement in the universe
This was a nice panel discussion. I didn't think I would watch the whole thing XD .
thanks for this video
Your videos are great science is so cool and trippy
My favorite quote here about time from the theoretical physicist being, if somewhat paraphrased, about putting a black hold near them and the comment from the moderator not being heard and not seeing photons of light to see him even existing
These brilliant people are indicative of how space/time is not yet understood even by our best.
Sorry but they're not the people for the job, it's like having a bunch of dentists trying to make breakthroughs in neuroscience.
Watching a debate devoted to time, that occurred 11years ago, adds a dimension to the interior dialogue one naturally has during such exchanges of ideas. Is it real, or is it Memorex?
As a Native American, I appreciate the flow of time in a manner that seems different than society at large. To me, the eternal now seems much larger and more encompassing than the past, which is limited in scope.
And the future is even more narrowly defined, like a microscopic cone that is limited to things I mentally select as likely targets of inspection. This happens in spite of the fact that I know many other events and destinations should be available. I simply lack a reference from which to launch my focus, as in more information about that future is required.
But that view is only a single aspect. Ideas, which seem to me to be projections of the self, appear eternal. The debate here, while 11 years in the past, is in my present, and is likely to be in someone else's future. But the ideas, though some have since been modified, remain as vital as when first uttered in 2009. (Vitality is not an property of correctness, nor the reverse.)
And each time we bring this discussion forward to a new present, it is both past and present, to our senses. Our mind observes both as present now, though we can mentally tag the debate itself as older than our subjective now, but we have to make that effort, or it de facto becomes now.
Therefore, it seems to me, that I the person, lives outside of time, choosing the place of self in the now only as a convenience to my corporeal body for its utility as a point of influence on the line of time recordings. It's my point of access.
To me, having grown into awareness with this system, there is a significant amount of bleedover from the past and the future. And this apparent phenomenon therefore enlarges, and perhaps distorts, my present.
The bleedover effect is strongest from the past, because it is able to also be solid in the now. The same effect from the future arrives in a more amorphous manner, such as anticipation, dread, desire, etc. Though more solid insights are occasionally available as well.
Should we someday acquire a more firm grip on this greased pig called time, that runs amok with our senses, we will become citizens of eternity.

It’s Memorex!
We have access to all these studies BUT seems you and I must come from a more sophisticated and more privileged type of money dare I say 😧

Very interesting discussion on the different views of time. A Theory, B Theory, and a mix of a few others. All in all, time may be the most mysterious of all the dimensions concieved.
Brilliant intro, quite brilliant.
It was a pleasure to listen to
awesome vid ! Prof. Roger Penrose & Prof. Horace Slughorn are thE same species !
I personally believe that like the double slit experiment, time is a construct of the observer. If we didn't make the observations of day to day life as this thing called reality. It would be hard to believe time would even exist.
I think the kid in the blue shirt just described the effect of time on a universe. By definition being outside a universe escapes you from its time.
People like to ignore the fact that we are moving at the speed of the earth + the speed of the galaxy at all times. I haven’t ever heard that number mentioned as our individual speed.
When referring to aging and time passage, Is our relative speed to the earth all that matters? That seems to be what everyone refers to. How fast is the dark matter traveling. What is our relative speed in reference to dark matter?
What is the effect on our molecular composition by our relative speed in reference to the sun and the black hole at the center of the galaxy?

1:21:18 If I am particle sized from the face of a giant, would the quantum wave function change and would the uncertainty increase from the giant's perspective? Would it be the same as us, humans, only being able to measure the position of a particle with probability?
If so, would it be fair to say that nothing has more entropy than anything else? Or that it's relative?
Congratulations penrose..! At last you have been recognised...
Time and Love are the only things that double when shared.
I have a simple question. If I drink a cup of coffee at a specific time and repeating it on multiple days then can we define spacetime for such days? They look identical unless we add a specific date. While mentioning spacetime why date dimension is ignored by Einstein or am I missing something? To me a moment in spacetime looks meaningless without a unique date that contrubutes in defining a sinple unique moment. Thank you. Riz
To say that the arrow of time is fixed because we cannot move backwards is not necessarily correct.
Play with this idea; say you can change the arrow of time just by wishing so.
So everything is happening backwards, then for some reason time changes direction again to move forwards, there is no reason you would be aware that you had just experienced the backwards event or that you had experienced the same event before as your conscience would move backwards with time thus being erased.
Therefore there would be no way telling whether we actually do change directions in time every now and then.
It seems that the discussion is limited by consistently putting time within the context of human consciousness. It’s hard to know to what extent this is a grammatical necessity or a real picture. To have an objective discussion about time, we have to make clear and distinct the elements that human perception could interfere with
The term that is the 'future' is one I strongly believe is interfering with learning different notions of time and the world. We cannot pause time. The arrow of time as they mentioned looks to be going in one direction and that we are measuring it in a closed system. In a sense, the future is a progression of probabilities and the future CAN actually be predicted, though it will have to be concluded by attaining many different variables. Like our probability of being involved in an accident, the roads we choose to drive, our own relative system of time with factors such as car and our mood, and the system of others would align a better conscience of probability.
It seems to me that there would be much less confusion if time as we experience it was called time, and the time used in physics used a different word, or maybe a phrase, such as Event Passage.
You're onto something there, what we're perceiving as the passage of time is just he passage of events, primarily the passage of the day and year.
Start watching this program from 8.00 minutes.
TY that helps
Careful not to touch some culture as well.
You mean 8:00 ,😂
its not like nothing was said cmon 8 min on 1h30 and some is not big ... impacience lol
It is interesting that at the event horizon time is said to come to a stop, and beyond the horizon time changes to a space, according to what we are being told...that suggests time becomes a place, allowing us to pick the location...but then we have no time within which to pick the location...so where does it go...or more to the point where do we go...what is our location in time and how does that appear in space. If we approximate will that be nearly right enough to give us the solution?
So beautiful
this has been the best one of these that ive seen.
what a lively host and amazing panel!
Hiceknloper was annoying...
please stop clapping into ic. otherwise outstanding
Understanding “Time” Is going through Dimension!
1:20:29 - Hold it. How does Many Worlds dodge nonlocality? One can still do Bell experiments under a Many Worlds interpretation, and one can still demonstrate correlations between "here" and "there" that defy Bell's inequality. Can someone elaborate on this?
I love listening to intelligent minds!
Shortest distance between 2 points is a straight line. BUT a voice can be heard miles beyond 🌎
is it the speed that you are going that slows down time? or the increased
mass that you gain by increasing speed?

We r all connected
I love this meanderingly long and wonderfully exotic waste of time. Thank you for this video.

Is entropy really the progression from order to disorder, from organization to randomness? Isn't the end result of complete entropy a perfectly uniform state where there is no randomness or variation?
I have question about the two entangled particles that has always bothered me since time heard this set of reason it goes as follows. If two partials can be entangle how certain one be that particles are the same two particles one started which later measured. The reason goes like this as the distance increase the provability that the starting two particles will entangle with other partials goes thus one has no certainty that one has the same two partials that measured at the final measurement are the same two particles one started with in the experiment? If this is true then the uncertainty increases with distance that one has same two particles one started the experiment? Is this true or false?
Subtitles please!!!
33:19 ...her answer should have been "superposition"
Perhaps we first need to know what energizes energy, (the big bang?) and if this is the case, time is emergent and consistent with the second law of thermodynamics.
It looks like we live in a predefined time block, as we grow and get older we get into illusion of passing time and try to define as past, present and future. As everthing around us consumes time to reach us, we respond to past events eg light sound vibration stimulai and others observe and react to our past actions not realising the time lag and define it as present. Our past is what we have lived already and future is what not yet lived and witnessed. Kindly correct me if I am mistaken in my opinion about time. Thanks.
Pace. Seems people forgot that we use to measure distance and time with our steps. Some dancers are said to be 'light on their feet'.
I see this event was quite some time back.
Well done for the statement that we do not know the reality and the ontologies derived from various theories do contradict, so we do not know what is true and we need to be open minded. Many prominent scientists put their beliefs ahead of what is known and give a completely warped picture to the public. Sean Carroll unfortunately is one of these scientists, he is a very good scientist but when he speaks to audiences he presents metaphysics as physics without explaining the biases of what he is stating.
I've always thought of time as a tool to measure decay.
The idea that the space between galaxies is expanding and the this expansion is accelerating could be considered a improvement to big bang cosmology. Perhaps, at one time galaxies were closer together but not packed into an infinitely dense space as the big bang theory postulates. Then slowly at first but increasingly faster over time the distance between the galaxies expands leading to the present separation of galaxies.
Einstein's ER=EPR can explain QM by vacuum energy ch=2*3.14*gm^2 which's solution of GR.
My question would be: Since they talked about beginning of space/time, how does that corelate to presumption that we live in a multiverse? What is between many universes? Is it space or time, is it nothing, is it space/time, is it infinity?
Different universe different laws. But could all those laws derive from some multi universal principal? Is time universal property for every universe, just that it behaves differently...?
The idea of the big bang theory a big explosion of all the matter to make billion's of large Galaxes and seeing pictures and doing no damage because of being so far apart in light years away. And Galaxes are in groups in different areas making it impossible for a Big Bang . This idea was created by Edgar Allan Poe 1809 to 1849 America Writer. He was interested in astronomy looking in the black sky and seeing little stars and thinking of it started . Having no idea of how it happened maybe something blew up that was very big mini little small pieces became the Stars we see in the sky even planets where bright lights like stars we could not see color the dark sky we know live in a time of street lights that do not make a dark sky at night I do not know where Edgar Allan Poe lived and where he was the spot taking the Stars to his mind being a writer he had thoughts I'd like to write them down and maybe to tell the story because that's who he's is Edgar Allan Poe we wonder where River start where big mountains have snow and the biggest mountains are only five miles high in ancient times the Milky Way was a woman arched over the sky milk came from her breast and dots of stars the Milky Way what's our universe became our universe we still call it the Milky Way from the Egyptians they have drawings showing this God created many worlds it is sad that our world was one of the worst because of people do not get along and are not kind to each other with love and understanding that they are different have different languages God thought they tried to make a Hightower to reach heaven but what they were using where clay bricks and would have fallen down because they work made of granite very hard Stone stronger the higher weight we make tall buildings made of steel framework the new ones we make now in New York are very thin built with floors with no windows to let air to pass through so that the tall buildings will not blow down
@@roberttrain3169 Nothing blew up at the Bing Bang.
It just expanded.
Universe is actually very uniform and simple at the glance. It all fits like a glove and if you take step by step back you come to the intesimaly small point.
There's no fairytale here. Just logic, proof and hard science.
@@roberttrain3169 How does any of that odd mix of myth, legend and nonsense relate to reality?
If our perception of time shows there was a beginning as we experience it, then there is likely to also be an end as far as we experience it. So despite our radical advancements in the future, we will need to also figure out how to change our experience through time to exist in a timeless state of the universe in order to survive. If we simply reversed time for our own experiences, this introduces time travel paradoxes: would we need to avoid ourselves in the past as we continue to progress through spacetime, or would it not matter, and we can destroy humanity as it were and continue converting every particle of the universe into computable conscious matter?
The presenter is a magnificent speaker, he truly is. Not a great walker but he more than compensates for that.
Agree wholeheartedly with ktx49!
Fotini Markopoulou-Kalamara is a qt3.14
Does any one know what book is the moderator reading at the beginning?
Carlos Leiva I dont know, but did you find the book?
Carlos Leiva. The Collected Poems of W.B. Yeats (1989)
Wow! Thanks! I'm really very grateful.
sooo, when you see something its a reflection from a light source. light travel fast but still takes time. your eye balls and your nervous system to you brain an back takes time. put both together time has been done. so your present outlook is a memory from the past . same with thoughts is memory of your eys past memory.
This means that we never experience now through sight.

Time is a concept only!
When you are alive, during your success time, yours is yours , and you can help the others, to go forward to the future, in present time .
Time before big bang maybe (initial condition):::: Something existed inside all of space, which was created by chance, then since it was so heavy, bounced into a single point and created the big bang?
When we discus time, we only discus ourself
If there is google of particles, there are googles of combinations. So ones started, it can't be finished. It even loks as only 'time' could catch time (combining). Are limits existence?
I prefer to think of 'time' in another word, 'processing' and also processing in one eternal moment, ask yourself the question, apart from physically looking older to others as you 'age' - do you feel any different, aside to life's learnings and experiences added to your collective mind intelligence, have you always felt in the now with yourself ?! Have a think about it as am sure you all have. Time is an illusion, a very good one, although it is not the way of Universe, do you see a huge clock in space? No... to understand eternity and time, you must first conceive that all is processing in the forever moment, whilst to be clear, yes we have memory, this is important in... yep.... processing... as also does our predictive sense of 'future', which becomes 'present processing' then memory, which is the residue of energy of whatever it is... still enjoyed this show as am sure others, felt to share this.
And the only thing we can do is just take r time with LOVE, PEACE, and FAITH
if the universe is actually expanding, this expansion provides an obvious arrow of time, no current moment can be identical to any prior moment as the universe is always larger than it was... no entropy considerations needed... simple novelty.
For those who don't know Caetano Veloso, he has a very beautiful song called Oração ao Tempo (pray to the time). Nothing scientifical but very beautiful indeed.

Congratulations to sir Roger Penrose for finally winning the Nobel piece prize!
FUCK YEAH AMERICA!
Uk*^ but we’re homies💪🏼😏
The Nobel pieces of eight.
the flow of time is fixed and never paused or reversed ,but time at any instance can be recovered from past at micro ,minute state of time
We have a propensity to think and experience life in a very linear way, past present and future. We have produced all type of theories to support and debunk that perception. Einstein personalized and differentiated our experiences as individual based on how we moved through space. I want expand on that it a different way. Let me first say I am not an expert or physicist, I have not studied the subject at length, however I like to theorize in my spare time, and I take on many universe questions.
In my thinking about time I want introduce my Ribbon theory it’s very elementary in its development but I believe some smarter people will get it and help substantiate it.
I want to introduce some definitions as I try and build and unscientific equation for my theory. Here they are
Te = Time Experienced O = Outcome
Ex = Experienced P = Past
Em = Emotion Ts = Speed (how quickly time move through our experience
Sc = Space constant F = Future
As always time theories are often paradoxical. So here are my equations for my overall Ribbon theory
Te = (Em)(Ex)- 0 / Sc
From an individual level the perception of time changes in its duration and speed based on our emotion and experiences. I’m sure we all have experiences of this. Time seems to move quickly at a major life events, for example it takes forever to plan a big wedding, but when the day comes its over in a flash. As for space I believe it’s unaffected by time and always constant.
Time is a ribbon that gets pulled through space based on Emotions and Experiences. Time in itself has no outcome it has no flow or direction it exist as multiple ribbons in space independent and randomly for our experiences. It’s very individual.
Outcome is accepted experiences that have no emotion we remember them but they don’t exist in time.
P= O - Ex
If it still has Emotion its still ribbon(time) in space and a potential part of our future. The Future is our unresolved Emotion yet to be manifested into experience it exists in our past.
F= Em - Ex + O
So in essence there is many different times to be had. It’s not as linear as we perceive and their existences are infinite.
biggest take away is Emotion it has to be added to every theory on time
Say we discovered a giant mirror 10 lightyears from Earth and somehow in alignment with our planet's trajectory. Now we direct a telescope towards the mirror. Will we then be looking 20 years into our own past?
If we could see the reflected image from Earth then yes. However, in reality no as the image of photons would become less and less as they spread out so that the photons that are picked up by the mirror would be extremely small and those reflected back and received on earth would be miniscule.
@@iain5615 How about if picture of Earth is taken from 10 light Years away and pointed towards us , 10 years later we observe it?
We could also move out a mirror first :) and use it to see our past, as we prolly do allready ;)
I love this comment!
The real question is why do we park on a driveway and drive on a parkway:)
Imagine you want to expand a point O in three dimensions point x,y,z. First you need energy to expand that point O, once you have expanded it in 3 dimension points x,y,z you have created time and expansion from one point to another point means motion, So SPACE ,TIME,ENERGY,MOTION are all one thing.
In my opinion, John Hockenberry’s treatment of Fotini Markopoulou-Kalamara was shameful during this debate.
I am a huge fan of this series, but I certainly wish they had a different moderator.
The notion of Before Time seems unanswerable without firstly observing all of the ingredients that were present.And secondly the action that occurred to the ingredients to make Time commence and go from stationary to instant inflation
What ingredients would have been present ?
What action occurred prior to the ingredients reacting ?
World Science Festival, has very brainy guess speakers, talking about Space/Time. Most agree that time travel is possible provided natural conditions happen at once twisting the net space creating a worm hole where light, energy, matter rotates in a funnel like a Whirl Wind or a Tornado were the true speed in the apex has yet to be truly known.
I think, considering an individual's consciousness, time can be looked first from his or her inner perspective, and second through his or her percivance towards the outer world matter. From inner perspective from person to person time runs at varying speed, which can be seen in the varying levels of energy and the personality depressions among us. But, still, these variations are bonded together through the second perspective, mentioned above as our percivance towards the outer world matter. This common dimension is one of the infinite dimensions of the time, which is explained by many physicists in the concept of infinite parallel universe. As far as one can see or understand from second perspective time runs in a constant incremental form. After 1pm we can surely predict that time would be able to reach to 2pm and nobody can stop or vary the speed of its progress in the normal conditions of our world. It is constant. We can assume that time is something that has a continuous definite path. A to B to C to D so on. Contrarily, our inner perspective of time is the only anomaly of our universe that has no predictive path. We can say that this path of inner time is completley personal to each individual. It can go to D from A or to Z. This unpredictability of our consciousness can yield many infinite possible and impossible thougths and many choosen infinitie action outcomes. For us time can be defined as the perceivance path that we choose and the remaining paths that we do not choose. The ability of predictiting what we would not choose out of all the options available definitely leaves us with the power of predicting the future. Moeover, Dark matter can also be defined through the nature of time. Dark matter is something that could have exisited in current time if time opted it to. It's something that we left behind that does not belong to this dimension, a dimension that moved forward. Our continuous variation in the consciousness, thoughts and actions in this manner define or act as a border between matter and non-matter. We can prove it theoretically as well. Decayed time of a uranium atom can be predicted. It is something that cannot accelerate or deaccelerate by itself. Therefore, time related to the matter is the same as the time of this dimension. If this point of view makes sense then this idea can help us in researching the dark matter and black holes from a very new perspective.
This idea can be related in the string theory as well.
On the other hand, if we look into ourselves, we feel that we have free will to choose the future but that's not 100% true, our free will also has its limitations there are few actions we would never do even if we can do. e.g. killing someone. Basically, at a time we act between very few choices, and these choices limit or define our future choices. so general relativity and quantum physics together can be seen acting together here. Quantum physics defines the raw material that general relativity shapes into something meaningful. e.g. our DNAs are the work of general relativity, but the formation of matter and their properties are defined by quantum physics. These ideas are different but work hand in hand. You can age fast or slow by controlling the relativity of the matter defined in your DNA but you can alter the matter's state also by working at the quantum level of the matter. I am sure that you can relate this to Einstien's notions of space-time fabric.
Time made of making, in Reciproction-recirculation, is Absolutely self-defining Quantum-fields condensation that requires none of the labelling schemes of Romantics, or Physicists with a possessive sense of entitlement because of they know that we don't. It's the New Age version of Pin the Tale on the Donkey, and if that seems offensive, it is only looking in the mirror of symbology and romance...
We r all living in time, if u want to see the flow of time its just like the flow of water
So as time is differently perceived by asu. Then as funny as it sounds. Our time zones differentiate plus or minus hour depending on lactation. But a moving object takes up less space , dang my eyes just crossed.
Even if time moved backwards we'd still see it at any given moment as though it were moving forward.
Yes! and because 'time' is a concept only.
Seems to me obvious now but
it took me a long time to realize that fact,
to overcome a lifetime of unthinking assumption.
Time is only how we perceive it. To understand time, don't we have to be able to perceive it from a different consciousness? Maybe we need to remove time (as it is not physical) from the equation. What if there was no "time", how would we measure the physical universe? We can slow down our perception of light (using slow motion videography) so in that act, we are wharping our perception of time. Further if we perceive the universe as light, if we add mirrors and fragment or reflect the path, we are wharping time too. It might be infinitesmal but it is wharping time based on how we perceive it. We need another alternative to time (or the concept of time) to test against time itself. In true darkness does time stop? Do we perceive anti-matter as the culmination of true darkness because density eliminates light and so is anti-matter anti-time? Does time move at all?
I have always wondered about the frozen lake of time theory. Some would thank that if you stand perfectly still then time should stand still but if you give it some thought. your particles are always moving and the world is always spinning so we are always moving. So what if you put some sub atomic particles in space and froze them to absolute zero would time cease and dismiss? We now that absolute zero is unattainable for their is always heat energy making particles vibrate, but if we could remove all heat and the particle no longer moved and the essence of motion was completely removed would not time itself be removed as well. Since atomic clocks meause the microwaves from cesium atoms, I wonder if we could find a way to send some cesium atoms into space and freez them to near absolute zero would we see a drastic change in the time of the frequencys. Just a crazy thought.
read a bit about the Bose/Einstein condensate...
Is what we hear the same reality of what we speak. Who is listening at the same “time”. If the moment it is over, why would anyone evoke the thought patterns involved in these waves and signals. If we could not comprehend light starting g somewhere. Should there be the possibility it stops somewhere. Is it predetermined in itself when it wants to stop and if so why would it be a “problem”. We don’t know it’s lifespan. Cannot linger, does it have memory. Is it not a substance as well as an energy source.
A little thought experiment...is spacetime real, as i need no space to travel time, but need time to travel space... ;)
Meaning that all we do, when we move is to travel time and create space in that same moment, like entanglement. That would also mean, that all we see, when we look at distant stars, is time past, that actually doesn’t need space to be in, as it belongs to something long past, maybe even our own past - in every direction we look out there. If what we observe is not space, could we travel there at all? This is the reason, why space expansion might be observed to travel faster than light, because light needs space to travel in and therefore must create space (which is only time) before it actually gets there, but somewhat in an entangled way, which concludes, that it happens in the same moment. Now, if time is something connected to an observer, and it expands differently for everyone, it makes sense, how we feel space expanding from everywhere to everywhere (we are not at the center of the big bang, but everything moves away from us). It’s just different timebubbles expanding, which have neo real barrier, like a bubble, but like our lives, connect and go through each other as all of time grows like some kind of foam, growing in time.
Or, Time is a concept only.
two observers do not exist to eachother until they have causality with eachother. At the moment of causality they agree regardless of where in spacetime they are. Meaning that spacetime is not a 4D static event observers move through independently of eachother. Take GPS.(atomic clocks) even though spacetime moves more slowly farther away from a center of gravity, causality between the ground and a satellite agree even with all other spactime effects for all observers being completely different in relation to eachother . The future only becomes now at any point in space once all observers that can effect that point effect it. Hence the future is not already written. I really don't know enough about physics to know if this is a viable POV. Would love to know if it is/isn't and why.
Traveling is only done relative to other objects. If someone travels at the speed of light relative to someone else, the person he is traveling at the speed of light relative to is traveling at the speed of light relative to him. Wouldn't their perception of time be identical?
Time is a matter of Mind (illumination, imagination. illustration). They are not separate from each other. Time also is difference between things and animals, or human,...
40:23 - I think that it was just coincidental that relativity came along around the same time that we were coming to have a deep understand of the "micro" laws of nature and recognized that they were time reversible in a way that the macro world isn't. Relativity didn't "cause" that. It was just a matter of timing. Newton couldn't SEE what was going on at the micro level.
Coincidental or not the turn of the 20th century just prior to the 1st World War was a monumental period for physics, chemistry, art, technology etc. IMHO of course. The sciences and arts were making changes to our ways of thinking and understanding. The snowball effect was unstoppable. Once again, IMHO.
@@godfreecharlie I definitely agree. I just don't think that relativity had anything to do with our recognition of the time reversal symmetry of the micro laws. I think we would have recognized that independently even if relativity hadn't come along.
@@KipIngram I thought "time reversal symmetry" was a product of a thinking process and reversal not an actual possibility.
Seems to me, Time is a concept only and deeply affects how we think about what arises in consequence of our sensory input.
I think if we can clone anyone or anything…..we need to clone Albert, we need him now more than ever!!
I guess I'm simple minded, but I entertained by this stuff.
Dan Baughman If you’re entertained by this then this may be where you should focus on.
The definition of being entertained by these things is viewed by me as what is defined as ”your true calling “.
You’re (true self) is calling you to (physics).
But you nor I were ever introduced to these type studies.
So I guess We take notes and develop our own theories of these events of Our Universe.
Continue your quest and keep watching because we’re learning for free!😆
Peace and Blessings to you and your loved ones Amen 🙏🏾
I found it slightly irritating 'cuz they missed the fact that Time is a concept only!
Think about it like it's radiating from a central point and it has edges like a sphere. What happens inside the sphere is projected on to the sphere surface. As it's radiating out from the center the projection on the surface leaks out from it spacetime in to another spacetime.
