In relation to Occam's Razor, I think time is the effect of atomic decay, without a process of decay there is no point of beginning or end therefor time only applies to that which consists of such matter. Essentially without this process of decay from beginning of life up until death you could not experience life for what it is, a linear timeline of experience, much like how a car cannot travel without the spin of a wheel. I don't believe time to be a dimension, the dimension is merely an illusion limited from an empirical perspective and completely collapses without it. It is however relative but only relative to the physical factors which we consist of as individuals. It's sad and beautiful at the same time, we live to die and die to live. I think everything in regards to theories of spacetime should stem from that foundation which will help clear up and dismiss a lot of wishful theorising in regards to time travel etc.

I think what Prof. Kaku wants to say is that elapsed time is reference frame dependent. It depends on the relative velocity of the object and the observer. People who are saying that I can measure time by a clock should understand that a clock is powered by the motion of some fundamental particles whose velocity with respect to the observer depends on the reference frame. Thus if you measure time interval by a clock then you are not measuring the absolute time interval. You are just measuring something called "time" which depends on the relative velocity of the particles which power the clock

Such great and differing views. Adds some different thoughts to something I have been thinking about.

Sometimes it sounds like they are pulling this stuff out of thin air and justify it using simplistic analogies that sound good because they are familiar to us. (typos)

Time must exist, or else energy would be immeasurable. That's the essence of the time/energy uncertainty relationship, I believe. Maybe time is an illusion, but it's an illusion that's imported into theory simultaneously with energy. Which is to say, it's a really fundamental illusion!

There also was no big bang and universe is not expanding, measurements doesnt fit, also CMB is not the first light.

@@jaymxu Let's say hypothetically, you had a theory of everything, and you had solved the universe. Here's what that might look like: It starts with some event, then consequent to that, each subsequent event is related to the initial event in an entirely deterministic manner. This is the perfect information solution to everything. Where's time in this model? It's nowhere, because you don't need it if you've solved the universal ordering problem. Thus, time is an indexing system that we project onto the universe. It is an illusion in the sense that a theory is a type of illusion. On the other hand, the remarkable thing about QM is that the uncertainty this particular illusion has exists in a reciprocal relationship with energy. (According to Heisenberg.) This particular theory (time) appears to exist in superposition with energy when measured. What's being challenged with this relationship is a naive interpretation of realism. The theory and the reality appear to be interdependent, when measured. They were never two different things.

@@mickfox3262 the only way we can measure how much time has passed is by assuming a repeat cycle that we are viewing (same distance, law of rhythm) is passing like a person dancing and stomping their foot on the ground. There is an innate sense of rythm built into our senses. but even then all of space could just be expanding or contracting relative to itself. So unless we have an external constant outside time space as a reference point, we actually don't know beyond our innate sense of the law of rhythm.

Time is an illusion created by our minds. The change we see around us, or more specifically motion, gives us this "feeling" of something passing us by. In reality, we never detect or measure something called "time", rather we always measure it against the motion of a given object, or mass. A day, 24 hours, is measured by the rotation of the Earth. A year is measured against the Earth's making one revolution around the Sun. Hours, minutes, seconds...all derived from the Earth's motions, measured by the hands of clocks. Atomic clocks? Determined by the vibrations of a Cesium-133 atom. All of these values we call time are the motions of one "thing" relative to another. What about General Relativity some would say...Spacetime? Spacetime is a mathematical construct, nothing more. Mathematics can describe what we see, but it too is a mental construct, a "language" of numbers, that can describe but cannot explain.

That's exactly right. However, I wouldn't call it an illusion, and instead rather that it's an "invention of human thought." Humans are good at imagining all sorts of things that are not real; we call it the imagination. But time is not a real thing as in being a tangible commodity; it doesn't have body or substance. As well, everything exists in the present (time) and there is no past or future (time). And the present (time) is apparently eternal, or must be so. So at least one big problem with trying to assume time has substance, or body, is that you must measure it against infinity. And since the present (time) must be eternal, or infinite, where all things exist simultaneously in the moment, it's not possible to measure against infinity. Even matter itself would not be measurable in a definitive quantity assuming that the physical universe itself is also infinite, which would have to mean that there is likewise an infinite amount of matter...

at 6:23 the speaker says Einstein, but his following sentences suggest he may have meant Newton at that point.

It seems to me we have a basic relationship when we describe simple motion which relate three basic quantities velocity = distance/time, which are mathematically related in a cyclic way. If we imagine a ball in motion we see it changing its position in space traversing a distance, relative to some reference point, and we sense the speed involved and the distance displaced. Both the motion and the displacement seem real. We cannot get any physical interpretation of time except in relation to objects being displaced in space. It is not time which causes motion but forces or space curvature. We necessarily introduce the concept of time to get a feel for the “quickness” of motion.

Time is process. The eternal now is a dimensionless point and it is everywhere. The direction of time's arrow is the breaking of the symmetry of the 'potential' of the boundary condition. At very fine scales, time may be reversable but once information is created, no process is reversable.

Mauldin is right. Special relativity defines time as what is displayed on a clock. It can speed up or slow down like a river. This is at odds with what Einstein said about the illusion of time, which suggests towards the end of his life he didn’t believe his own theories that made him famous.

+1 to your comment. It is their way of making money by twisting minds of people that did not enough.

Time is a way to measure Change. Time is digital, Change is analog. Change _unfolds_ in a linear manner but is not restricted to unilinear directionality. Change also leaves an energetic trace, a record of the complex vibrational signatures of "each moment" that has happened. The concept of simultaneity is a misinterpretation of the recognition that all time is accessible; through occasional time loops, the energetic record, and through the probabilistic vector _potentials_ of the future. Physicists are mixing contexts when they are trying to model change in terms of measuring time and this leads to many misconceptions, including that there is no time, simultaneous time, or that time doesn't matter (because the math says so).

What the second one said is correct because Time is a process not a dimension nor absolute thing.

Is time the product of consciousness?

Recommend a recent paper about time contraction interpretation (DOI: 10.21275/SR23918031232). Lorentz´s time dilation is a scale change in time value; not the passage of time! Imagine a proper clock where the values at the dial change following its energetic content (General relativity = energy produces time dilation and length contraction). For length contraction, imagine an engineer ruler, the value depends on the scale selected BUT the ruler occupies the same space. Returning to the time dilation, for photons at speed C, their scale will indicate no change in value; i,e, length = time = zero. Imagine again the proper clock of the photon with the same number all around the dial... The moving handle will give a time difference of zero, meanwhile, its handle is synchronized with the rest of the universe. In the twin paradox, the traveler brother can shake hands with his brother on Earth, both with different time values but both at the same passage of time... very simple... hope you like it, regards

Physics would not exist without "time" because all physical motion is measured in duration. Quite simply, without at least an instant of duration, nothing is measurable. Perhaps "time", or more precisely duration, should be considered the first "dimension" because "time" elapsing facilitates all observation and an elapsing duration is as much an aspect of our reality as length, width, or depth. Therefore "time" is not an illusion, it is just poorly understood. From my perspective, Michio has become very difficult to listen to.

There is a lot of quantum mechanics that physicists skip. I read books by Greene and Kaku and I think they both have a solid grasp of the underlying principles. It just isn't something you can explain in 30 seconds

Time is the length between two points of smaller dimensional construct. ❗⭕

String theory like the big bang is no longer fashionable.

If you base your measurement of time on something that vibrates and it turns out to be true that things do vibrate different rates at different locations that only means your measurements differ. It does not mean actual objective synced time across the universe has slowed down.

He's right. The lorentz transform is just a trick on perspective. Any good artist would understand that. The real question is does perception of time slow down the faster you travel. Einstein was smart but he needed to take some art classes.

I personally believe that these academic topics should not be discussed like newsroom debates

At the most fundamental level, time is existence, almost trivially. If anything exists, then it exists in time. If there is any change, then time can be said to flow. If nothing changes, then time stops flowing. The rate of flow is meaningful only if there is a subpart of the universe that goes thru a cyclic state. If not, then the rate can not be measured. Time flows in only one direction before to after. We use the word forward flowing time, which misleads us to think that backward flowing time is a meaningful concept. it is not. The order of events is the direction of time. Entropy (with high likelyhood) increases in the direction of the flow of time i.e. statistical 2nd law of thermodynamics. But time does not gain its direction because of the entropy increase. In other low entropy in the past - the so-called past hypothesis is not the cause of direction of time. Even when the universe will reach thermal equilibrium, as long as there is change, time will flow. Of course before you protest, there will be nothing to perceive it. Therefore, in all of this discussion, I am talking about physical time. I am not talking about the perception of time by a conscious entity.

We still arguing over time? And time is a word that represents dimensions and not the areas but the properties. Space is the area and time is all that within in a superposition because it’s unmeasured or undefined. Once measured you can collapse the differences in relation and see the whole of it all.

These people never heard of Vik Grebennikov, but that's ok. They are all hopelessly lost pushing their own theories but I can nicely shut down this mindset and enjoy how Vik built and used his own anti-gravity platform.

there are almost no physical equations where time is involved. It is a useless quantity that only has subjective meaning for human perception

Time is related to mass. Without mass there is no time and no space either. If you look at an empty patch of space, you can't see time flowing and you can't tell how deep it is even with radiation present. But the moment radiation condenses to go round in closed loops to create matter, then you can count the number of turns made by radiation and this is your time- the Zitterbewegung. It is a scaler(counts) and it is in one direction and always increasing. If you have a second mass then you send light to that mass to reflect back and count the circulation again for this to happen and this is your distance- since the speed of ight is constant. This is exactly how the International Standard defines time and space- the meter scale.. by vibration and by wavelengths(c/f). regards.

time is an illusion that helps things make sense, so we're always living in the present tense. It seems unforgiving when a good thing ends, but you and I will always be back then singing "Will Happen, Happening, Happened" Just kidding, i love this song

Of course time would be... time doesn't exist outside of human perception. We perceive past as memory, presence as sensation and emotion, and future as abstract thoughts. Time in physics is relative to gravity waves in the "river of time" as he says. We live in something like a bubble that formed between colliding gravity waves. Creating a quantum foam of bubbles of gravity vacuums.

They didn’t even touch upon the fact that quantum mechanics requires an absolute now.

The thing is you can argue about this is all day but on really well probably never fully an l understand much. I imagine that the universe is a billion times more complicated than we think. With no beginning and no end just changes.

Kaku can't make any statement without introducing the crazy multiverse.

10:00 Einstein was a good physicist but he never understood Time.

Time is a relationship among mass events. In a quantum paradigm time disappears when an event disappears. Time recurs with new events

Did Kaku have a stroke? The right side of his face is slack. Not poking fun, actually being genuine in my question.

Between any two points in space, there is but one point in time, between any two points in time, there is but one point in space?

4:00 Maudlin on Einstein's letter of condolence

Wow... first time I hear Maudlin say something that's utterly correct. Maybe he is not totally "outta there", after all. :-)

8:20 paradox means one of two: wrong equations or understanding and interpretations.

Particles with a pilot wave motion, over time; the waves have a time period. But, our perception of reality is a standing wave, that is modulated to form our reality. How many planes or dimensions are involved, who knows? But the standing pilot wave implies no arrow of time for humans. And a standing pilot wave implies a mismatch, perhaps from a particle asymmetry in the volume of the cosmos.

I like Tim as a lecturer or during one-on-one interviews, but I find he can appear borderline-belligerent, condescending, and dismissive in conversations with those he disagrees with regarding academic questions. I say, "appear," because I can't read his mind and some people can sound more emotionally invested than they actually are, but I think the content of what he says supports my original statement.

7:00 Time is a process means automatically that it’s relative, that doesn’t need Einstein to prove that Time is relative! And Gravity and acceleration affect the tool of measuring Time not Time itself (because Time is a process).

The electromagnetic spectrum does not have time , the material does Time is relative to the material world , and we define the arrow . Same as language. Language does not exist , it’s a model of time The reality of time exist , because we do lol we are the measures that average it

Anyone ever heard of Einstein’s friend mentioned named Micaela Bessel?

They baited me with an interesting Short, then dropped Michio on me 🤢

What no one here considers is whether the belief in time, or the disbelief in time, has any meaning absent a coherent concept of why time was ever posited as a real thing to begin with.

I'm not a physicist and can't speak about the quantum multiverse, but the flow of time and distinction between past, now and future must be an illusion. These concepts just make no sense outside of human experience. If time was "actually flowing", the universe should've started and ended in an instant, and nothing would exist anymore. You can describe the distance between events in seconds and Planck time, but once you imply that things "actually flow" you now need some subjective "rate" of time flowing on top of those physical units. It's gibberish. Like postulating that "colors" as sensations actually exist in the universe.

Yes sure. But time as the approximation or even the image in a mirror - made constant - is helpful for comprehension. A complete cacophony of “multiverse” is cute random palaver for a lab.

Time is a moving smear that leaves no residue except with interaction with a black hole or a phase transition/particle death. Have a great weekend everyone

Imagine that time is a singularity, everything that has ever happened is there, consciousness is linear it can move back and forward perceiving time at a biological rate. When a universe is created all events are created. We live in a Time Black Hole.

4:20 he has nothing to add to science, he only makes noise and media played a bad role in that.

Time is the 'shadow' of physics, all physics is Motion.

I believe Dr. Kaku is right in the sense time is an average which is based on earth orbits. Think about it. What would time look like if based on a Saturn 🪐 orbit lol!

inertial and gravitational forces are similar in nature and usually indistinguishable! Very likely Gravity interacts with each particle independently regardless of its location to other particles in the same object and that’s why all objects fall at the same rate. very likely the happy dream of Einstein is just a simple dream! By taking what mentioned above it’s much easier to understand why inertial and gravitational forces are similar in nature and usually indistinguishable! I have noticed the way they deal with small g and big G in physics equations, there were good physicists in the past such as Newton, Maxwell, Planck,….etc but they never had good understanding of the fundamentals of physics such as space and constants.

Only need two dimensions to create the illusion of three. One dimension is time, the other is the physical singularity of the big bang. The rest is projected onto the surface of the singularity. You're welcome.

In my opinion, Time does not exist to the contents of the universe. Time is an invention of the consciousness to evaluate change. Let me ask you. How old are you if you travelled in a straight line or in a direction that does not loop in the universe? Or, how old are you if you are in a fixed position in the universe. No time to tell and so how would you break down increments to describe your appearance in the universe. However, I am moving in circles which does not tell me my age, rather I have traveled around the sun on a planet in 45 plus orbits.

Avshalom seems to be a philosopher debating with scientists. He just ignores the bulk of information to quote letters and philosophers. I get Tim's position and agree with the bulk of his explanation, until you get to quantum phenomenon that have negative event horizons, aka particles that travel backwards in time.

Is time incompatible with physics? Huh??? Time is part of physics! And for quite some time!

You guys need to learn emotional regulation. It’s okay to debate and be friendly!

I believe I already have the show and it's ready to go. EMFS theory. It's all in.
