I agree. Speed, rate, age, fast, slowly, RPM, acceleration, clock, schedule, regular, rhythm, beat, arrhythmia, nanosecond, retarded and seismograph are all words whose meanings are derived in part from their linkage to a concept of time. The concept assures us that time is an actually existent fundamental component of the universe and an important consideration in scientific physics. I'm sure there are many other words like these that belong to our 'temporal vocabulary'. How could one grow up in a society whose language is saturated with that vocabulary and not be certain that time is a reality of physics even if quite mysterious. That particular temporal concept becomes an unconscious assumption that influences almost everything almost everyone thinks and does. It is no wonder that so many resist the reasoning that reveals time to be a concept only. You may have noticed. lol Cheers, eh!

When your boss asks you why you are always late to work just tell him he lacks the necessary awareness to understand that there is no such thing as time. And then see what he does.

What Carlo tries to explain is that Time is an emergent property of each quantum event. Humans can´t discern and account for all those micro events so our brain creates an approximation called Time. Example of an air ballon. Our brain can´t process all the position and velocity of the air particles. Instead, our mind takes a probabilistic account and extracts variables like volume, temperature or pressure. Carlo affirms that same happens with time.

I'm commenting on the video not the post above: Carlo has a point. Space and time are one. More specifically, there is only space. The time we know changes with space/curvature/spacetime/gravitational waves. 7:43 the sense of time comes from our senses. Without our senses, we perceive no change or time. However, his point is not entirely useful. if something is local (general relativity), events are comparable and the yardstick to use is the speed of light/causality. GR also made it possible to compare objects in spacetime.

Gravity affects the oscillations of an atom in an atomic clock, so that the clock speeds up or slows down depending on altitude or proximity to mass. I think that a clock is correct or incorrect depending on what it is calibrated to. My wristwatches do the same thing according to the effects of gravity, but I don't tell my boss that I'm late because time sped up. I say that my watch is wrong. I'm not saying that the scientists are necessarily wrong, but the explanation falls apart for me very quiokly. I really wish that I could fathom time, but alas, it must be beyond my grasp.

The only theory of time or definition of time that does without the assumption of progressing without the change of physical objects is to literally define it as an emergent abstraction from fundamental change. When you say your watch is wrong basically you're asserting that RELATIVE to other watches or an earth based time system the watch is too fast or slow, relatively. I always find these responses objecting to a substantivalist interpretation of general relativity tiresome when someone asserts it's not time that slowed down but how fast this process changes. . . but that is all that time is. In fact, without a universal or even relative (as in special relativistic) ticking of spacetime clocks in what sense does it mean to assert that this process did slow down but "time" did not? plato.stanford.edu/entries/spacetime-theories/

This is finally getting at, a century removed, what Einstein blew out of the water: time does not exist, and we need to reexamine our experience.

very well explained imo

Time has two distinct meanings. 1. The dimension of change...i e. the calibration and indexation of change and change events; 2. The collective noun for the 'flow' of change events. Both dimensions and collective nouns are abstract. Time is abstract; change is the tangible fundamental. Every quantum particle, every atom, every molecule, every living being, planet, galaxy changes continually. Change is reference frame specific, and fundamental. Time is a mere abstract word with two core meanings..make sure you know which meaning you intend applying.

I theorize that time and information are fluid like within the Quantum Gravity Field,past,present and future and all the information that will exist in our universe is intrinsic to the field!

The host is right. This sounds like semantics and it seems to depend on how time is defined and how change is defined. To some change and time are synonymous for example. Replace the word time with change and we are left with the same question. Is change an essential feature of the universe? Of course, we can then ask is there is something more fundamental than change and would it be correct in calling that more fundamental idea 'Time'.

Does someone know who is the gentleman interviewing Dr. Rovelli?

What does time relation to gravity say about causation, for example, gravity causation of the events of things falling to the earth?

In the reference frame of light speed events is it not true that time has to be undefined by virtue of special relativity? Using Einstein’s great mass energy equation and taking the snapshot second differential to eliminate time - I resolve there to be two mass areas. If correct - does this not reflect the symmetry of the particle/ antiparticle and possibly the whole universe/ anti universe, and that cosmologically and beyond perhaps one can see just how illuminating the removal of time may be? Is it true that being able to get the measure of the universe in its simplest or most fundamental state of order by the removal of time, may be the key to the workings of the higher level complexities? Just a thought from someone who knows very little.

When we say that a photon is a particle and a wave, what is waving is probability, it might be no better than saying that what is waving is the relationship between space and time and that dimensions emerge in both space and time relative to the observer.

"It's Newton that has convinced everybody that there should be a time independent of change."

Yes, excellent In the fields of Science and Philosophy Robert Lawrence Kuhn is incomparable as an interviewer.

Time is definitively not absolute for sure, however it is the base humans have to study events, correlate them and put them in a sequence throughout life. When professor says that if a object is standstill theoretically there is no time is not precise in my opinion because in every milliseconds of time something is happening. An example is a stone that is standstill, for us it seems nothing is happening therefore and according to Modern Physics there is NO time. On contrary, the stone atoms are interacting with environment all the time since there are changes of temperature and pressure for ever and atoms have to change accordingly. I think that time is the base for study of events and nothing reasonable has been presenting along the history (time here again) to replace it. I would avoid to say that time is wrong if there is nothing to replace it. Again, apparently there is no change on standstill objects BUT there are, since variations are happening all the time in everything. Despite my different opinion I admire Dr. Carlo due to his contribution to Physics and I recognize that he can be right or I could have misunderstood his view.

Could we have an emergent future unfolding photon by photon with the movement of positive and negative charge? In such a process the future would unfold at high temperature in the form of stars (plasma) above us and also it would be relative to each living cell within us! We have the distribution of charge relative to each living cell of our body so such a theory would be totally logical.

For me personally, I currently believe that what we call "gravity" is a part of what we call the "photon" and the pulsating photon is the energy unit of this universe. There are only two forces of nature, Gravity and EM, (GEM). And possibly there is only a single force with three different modalities. I have a test to test my latest Theory Of Everything idea, just not the resources to do so. But basically the test is as follows: a. Imagine a 12 hour clock. b. Put a magnetic field across from the 3 to 9 o'clock positions. c. Put an electric field across from the 6 to 12 o'clock positions. (The magnetic field and electric field would be 90 degrees to each other and should be polarized so as to complement each other.) d. Shoot a high powered laser through the center of the clock at 90 degrees to the EM fields. e. Do this with the EM fields on and off. (Possibly even trying it with different strengths and depths of the EM field.) f. Look for any gravitational / anti-gravitational effects. (Including the use of ferro-cells to be able to see the energy fields.) If effects are noted, then further research could be done. If effects are not noted, well then, my latest TOE idea is probably wrong. But still, we would know what gravity is not, which is still something in the scientific world. I would copy and paste my latest TOE idea here as I used to be able to, but KZread recently changed their policy to not allow at least me to not be able to copy and paste into comments, don't know about anybody else.

Entropy is changing also. 2. The whole Universe inside the frame marked as Now Moment is separated from previous Now Moment by shortest possible separator Planck-time. 3. Last Now Moments are Record, History, Memory or Information. Next Now Moments are next changed states of the Universe inside Frame. 4. Only Now Moment Exist. Past and Future do not exist. Flow of Time forward or backward does not exist. No arrow of time. It is arrow of Change with elapse of Time. Moment is ticking repeatedly at Planck-Time interval with a new 3D-Photo of the Universe. 5. Conscious Mind can make predictions of next Moments from experience and can plan events for next Moments. 6. Every Planck-Volume’s “Now” of the Universe including space and stuffs in it is always in the same Now Moment Frame of the Universe. Relative Clock ticking, fast or slow, at different planck-volume for different conditions does not shift anything to previous or next Moment Frames of the Universe. Because clocks ticking slow or fast does not mean Time elapsing slow or fast. It is error of the clock for certain condition which need to be adjusted. All points Now remain in the Now Moment Frame of the Universe. That is why twins of paradox can meet at any ones Now though relatively they are backward or forward in respect of amount of time elapsed. Time travel is not possible. Our invented Clocks and Calendars are misleading us about time in the repetition of day & night and seasons. 7. The Unit by Clock is three dimensional at any point of the Universe. X axis: Universal Period of Time, Y axis: Passage or Elapse of Time and Z axis: Local Present or Now. Our Clocks only show one dimension: passage of Time. Clocks are good measuring device with a Unit but that is not Time.

Thus, the fact that time is different higher up in the atmosphere doesn't matter because it is of little utility. Time DOES exist here at ground level because it is of utility and can be measured for the purposes needed at ground level. Therefore, just because there are many different ways of measuring time does not eliminate the notion or perception and most importantly the utility of time.

Is there ever “nothing happening”?

So, here is the way i look at it. Lets say there was one particle in the entire universe, only one. How would that particle measure time? Well if the particle is moving, because its in an inertial frame, ie the rest of the universe is empty so it wouldnt know it was moving. If it was spinning, again it wouldnt know it was spinning because there is nothing to compare its spin to. So how can you measure time? At this point, time doesn't exist. Introduce a second particle, now maybe you could say these two particles are moving away from each other, but without another paticle or measuring stick, you could measure distance but not distance over time. If one of the particles were spinning, then all of a sudden you can say the distance between the particles increases by so many particle lengths per particle rotation and voila finally you have time. Time, is nothing but a measure of movement vs another measure of movement. Here is where my ideas gets a little complicated. I believe we experience three dimensional objects in 4 dimensional space all the time. From our perspective, there is no difference between two particles at two different depths in 4D save that one of the particles may appear smaller in one dimension. So, just like on tv we experience a three dimensional world through a two dimensional lense, we view a 4 dimensional world through a three dimensional lense. Though we can only see in 3d, there are ways we a can interpret the distances along the 4th d. (bare in mind that the 4d is polarized because as 3 dimensional objects move out of our 3d into 4d, it only shifts one of its 3 planes that are at 90 degree angles to the existing xyz that we have currently because the 3d object still only has 3 dimensions.) So lets talk about time dilation in a gravity well. Its the best way, that i can think of to try and explain what i mean. I think particles always move at the same speed regardless of where they are, what changes is the distance through a 4th dimension this particle has to travel in order for it to interact with the particles around it. As example, we take two people, one in space and one close to a black hole. Both people are in some form of a gravity well. the person in space is in one created by the mass of his body, the one near the black hole is in one created by the mass of the black hole and the mass of his body. Imagine both people as being on the side of a cliff that slopes slightly away from them, as in on the side of this gravity well. you are looking at them from above, and for our sake, through a 2 dimensional lense. From what you see, the two appear to be only 2m apart, but if you flip the lense to the side, you can see they are separated in height by a 1km. In order for anything from the person deeper in the gravity well to interact with the person outside the well, he has to climb 1km to cross the 2m that from above we can only see visible. All particles in a gravity well do interact with other particles in the well but because of the distributional changes in gravity, the distances these particles have to travel via the invisible dimensions different distances in order to interact. The deeper the well, the sheerer the cliff and the more they have to travel along that unseen dimension to effect change. Lets look at it from the perspective of a radioactive particle near a gravity well that is decaying. Lets say that a proton is going to escape the particle. I would say that the proton is always moving away from the nucleus, but because of the deep well, that proton, though from our lensing looks close to the nucleus, is consistantly traveling further and further away via the unseen dimension. Compared to a same radioactive decaying particle in free space, which decays faster because there is less of a cliff, either up or down, that the proton has to overcome before being able to be visibly away from the nucleus. So far, i think all this makes sense. And in this way, time dilation would just be a matter of figuring out how steep the cliff is. If we look at time dilation due to speed, we get sort of the same outcome. If one were to go the speed of light, the energy constraints would be astronomical, your mass would increase infinitely, you would be moved, via the unseen dimension to a position where you could see the universe unfold before your eyes. Because every aspect of the universe would have a less steep cliff than you are at the bottom of, all movements in the universe would happen quicker than any movements you, or any particles of your body would make, thus you would see everything move at ultra fast speeds and you would witness the end of the universe. As for length contraction, this occurs as one of the physical three dimensions shifts towards one of the unseen plaines. as the object turns towards this plain, the distance between the particles look smaller and from what we can tell the object seems to shrink. its important to note the same thing happens in a gravity well. A black hole isnt really a singularity, its that matter has move out of our 3 plaines along the planes of the 4th d. so imagine a 3 dimensional object in 4 dimensions barely touching our 3 dimensional space. As an object moves down a gravity well it seems to get compacted because its further away. someone let me know if any of this makes sense.

Dan Jacob The missing piece is that the Big Bang came from a tiny volume, and quantum theory says that there was only very few pieces of information, possibly only a few hundred bits. When this expands exponentially, any new information comes from quantum interactions,, which means that the beginning is very, very smooth, and gradually new bits accumulate in larger and larger structures, while energy is transformed and disorder is produced. That's the second law of thermodynamics. It becomes impossible to wind it back, it would take more energy than was already released, and we lose the information needed to put things back. The universe can only evolve, there is no going back. The past doesn't exist, the future is fundamentally unpredictable. However the increase in complexity is not random, life is not random, as disorder accumulates in stars, to be finally trapped in black holes, while their "order" or high energy, low entropy photons are radiated onto solid planets, allowing information to select itself by fitness to reproducing the data, in a slowly changing environment.

"If there is no time, but only change, then change could be reversible." OK, I'll actually agree with that. Here's a thought experiment: Is it possible to change space? We know that it is, on a small scale. You can take a deflated balloon, inject some gas in it, and significantly change the space (volume) it contains, the volume it displaces, its surface area, etc. I don't know if space can change on its own, but it can be manipulated, given the necessary technology. Is it possible to change waves? Of course it is; we do that all the time. We can produce waves all over the electromagnetic spectrum, we can combine waves to heterodyne them, we can filter or modify existing waves, etc. I don't know if waves can change on their own, but they can certainly be manipulated, given the necessary technology. Is it possible to change gravity? Yep; happens all the time. Space debris accumulates, its combined gravity draws in more and more of it, and soon it becomes a satellite, a planet or even a star. And humans could certainly do this themselves, given the necessary technology. So, if we can change space and waves and gravity, then perhaps believing that we can't also change time demonstrates more of a lack of imagination than it accurately reflects reality.

Time is the sequel of all events

@@barryzeeberg3672 yes, you are correct. To be fair it is not easy to come up with a new concept of time that could actually work to explain the world. A new concept of time sould explain phenomena beyond GR and QM. But at the same time it needs to build on the successes of those 2 theories. We need to consider the limits of GR and phenomena that today cannot be explained by GR. Two major phenomena that come to mind are the ones caused by what have been labeled as Dark Matter and Dark Energy. The others are unexplained observations like the flatness of spacial universe. GR does not predict this flatness. Using GR one would rather expect a universe with an inherent curvature. Flatness is highly unlikely and similar to seeing a pencil standing on its sharp tip. Other results of GR that are unphysical and point to its explanatory limits are the singularities of the Big Bang and Black Holes. GR gives rise to these singularities which indicate its weakness and a need for a more robust theory. I think a new concept of time has to explain all the above and not just be a clever new rehash of Einstein’s old ideas.

The measurement of time must remain static for you in order to measure time it only gets weird between reference frames.

Physicists still have not got it right. We exist within a 4D environment called Space-Time. However, we are confined to real-time, thus we do not extend across time, thus we perceive a 3D environment. All matter within this space-time environment is constantly in motion and does so with there being just one specific magnitude of motion. That magnitude of motion is identical to the magnitude of motion of which light has as it moves across space. As I have said, we are confined to real-time. This is the inside of reality. The outside of reality, is all time of the space-time 4D environment, other than real-time. An event can be governed by circumstances set in real-time. These are inside events. A 4D event is governed by circumstances set across a measure of time. These are 4D outside events. Depending on which side is in control of an event, is what determines what the outcome of the event will be, since the laws of physics are different on these two sides.

"IF" time does not exist, then there could be no speed of light, "speed" being distance divided by "time". Also possibly: "Yes officer? I wasn't speeding because speed does not exist because time does not exist, (speed being distance divided by time)." See how far that gets a person in court to see if time and speed actually exist or not.

For me: "Space" is energy itself. Wherever space is, energy is. Wherever energy is, space is. They are one and the same thing. "Time" is the flow of energy. "Time" (flow of energy) cannot exist unless "space" (energy itself) exists. "Space" (energy itself) that does not flow (no flow of time / energy) is basically useless. An entity can't even think a thought without a flow of energy. If "space" (energy itself) did not flow, "time" (flow of energy) would still exist, but it's flow would be zero. If no energy flowed in the entire universe, wouldn't we say that "time stood still"? But hence also, "space" (energy itself) and "time" (flow of energy) are linked in what we call "space time" (energy and it's flow).

+Dee Ess I have taken my mind from eternity past to future eternity and to the "realm of all concepts" where space, time, logic and reason don't even exist yet but yet everything that could ever be exists. I don't know how much more open my mind can be without changing my very nature of existence itself. As far as "space" and "time" go, in addition to what I said above: I believe what we call "gravity" is a part of what is called the "photon". I also believe that the pulsating photon is the energy unit of this universe. Everything in existence is "light" (photons) in a universe entirely filled with and made up of "light" (photons). "Space" and "time" pulse at the singular energy unit level. When energy units unite with other energy units, they would tend to stabilize and vibrate, hence "space" and "time" would also tend to stabilize and vibrate. This also allows for "space" to bend and "time" to vary and warp. Continuing on: If each energy electromagnetic radiation frequency was looked at as being in their own "space" dimension, then there are not just three spatial dimensions, but many, many spatial dimensions that all interact in a way that we only perceive three spatial dimensions. In addition, if each flow of energy were looked at as being in their own "time" dimension, and as there are many different flows of energy, one could also say that there are many, many dimensions of time, not just one. As all those time dimensions interact, we only perceive one dimension of time. But, there are most likely many more space dimensions than just three and many more time dimensions than just one. Open mind enough for you?

The question is: what is fundamental? If you think about distance as being fundamental, that seems wrong (or only an approximation), according to special relativity. Distances compress or expand, as seen from different reference frames. Similarly, time itself changes according to effects imposed by special and general relativity between reference frames. None of this means there is no speed of light. In fact, it is the "speed of light" which seems to be the fundamental quantity by which both distance & time are affected. The only things we seem to know for sure is that things change in relation with each other, and massless things propagate at light speed (the fastest speed possible, which things with mass can only approach but never attain). Energy, it seems, is some kind of a placeholder... it seems nonsensical to say "space is energy", because "energy" is an amorphous mathematical construct. Energy has a bunch of different forms, all of which, when added together, leave us with a constant (perhaps even the constant zero [or just the tiniest of positive values, i.e. the "zero point energy"], over the whole universe). We have kinetic and potential energies of many types, micro- and macroscopic. To simply say "energy is [x]" or "energy is [y]", like it is a single fundamental thing abuses not only the language, but also all the equations that use the concept -- i.e. the reason the concept was developed in the first place. It makes much more sense to simply say "energy is that quantity that is conserved", and leave it at that. When violations of conservation of energy are discovered (as what seems to be the case now on galactic and greater distance scales), then another placeholder is made to make everything balance out again (which is why physicists are now postulating "dark energy", even though no one knows what it is - or even if it exists for sure). See: en.wikipedia.org/wiki/Forms_of_energy
