    This guy is fantastic. What I like the most about his lectures is the simplicity in explaning the things that are hard to comprehend even for the most brilliant minds of our time, in a way that it can be understood even by a simple mind like my own. I enjoyed every second of this video.

      Hey, I'm sure your mind is more complex and capable then you let on. You've communicated clearly without misspelling several words or jumbling ideas together. Quantum mechanics runs opposite and certainly contrary to our normal human intuition and thus one must develop a new set of senses to properly conceptualize/visualize what's going on. You should look up Leonard Susskind at Standford and his lectures theyve put online. He's really a master teacher of physics and math. I'm completely self educated and, as far as classical physics, have really developed an understanding that is simply not available on these trash popular science videos on UA-cam.

      I completely agree, I think was Richard Feynman who once commented somewhat dryly that, "Anyone who thinks they understand Quantum Mechanics doesn't."
      There's nothing new here at all, nothing that hasn't already been well covered by people like Lee Smolin, (and many others,) in his excellent book, The Trouble with Physics.
      It's all very well jumping up and down, (and doing the eccentric scientist, "thing," to the hilt,) shouting we're on the verge of a great breakthrough we must be.
      The problems are real and well understood even by many laymen but neither of the two main approaches String Theory, (untestable by experiment,) and Quantum Loop Gravity seem to be taking things much further or to offer any such breakthrough.
      The discoveries, (basically just the Higgs boson,) at CERN and LHC have been to say the least, disappointing compared to what we were promised and again non of them seems to take things much if any further in explaining stuff like why there are no left handed Neutrinos, Dark matter and Dark energy and so on and so on.....................................

If you notice that research and observations in only 4 dimensional space time is starting to hit a brick wall.....that's a tell tale sign that new branches in science need to open up.....❤

  • @thedouglasw.lippchannel5546

    Nima Arkani-Hamed is a genius! Thank you!
    The intent herein is to offer for consideration, in the context of this talk, a new definition of space consistent with the CIG Theory, which has already offered a new definition of Matter.
    That new definition of Matter is: That which has mass, consists of the curvature of space-time and has an element of motion.
    While the current definition of space in its simplest form customarily is:
    "a boundless three-dimensional extent in which objects and events occur and have relative position and direction"
    As can be seen, since we have redefined Matter in the context of the curvature of space-time, we must also redefine "Space" as well, herein and as best I can, as follows:
    Space is that three dimensional extent in which objects and their events occur, wherein those objects of Matter are they themselves curved space-time, wherein the aforementioned space consists of and emerges via the unfolding of that Matter into various volumes and densities of Space by way of opportunistic rates of motion of Matter. In it's simpler form, Space is unfolded Matter, emergent from rates of motion.
    That's it and if I come up with a better definition or if someone else would like a try in the context of CIG Theory, please have a go at it.
    In this manner, a particle can become spatial and go through both slits in the double slit experiment.
    Any replies?
    Nima is the best.

    Nima's talk at Harvard SPS entitled "Chilloquium 2022" is reasonable starting place to think about these things with a concrete example. But the lecture I found most useful was back in July 2020 talk at ICTS String Seminars entitled "Spacetime, Quantum Mechanics and Clusterhedra at Infinity". I've had to watch all his recorded lectures on this subject over the last couple of three years - more than once. I don't understand all the maths, but I totally get his ideas now. Anyway, it seems like a very exciting time for us all to live through. Had it not been for the 'pandemic', I probably would never have had the opportunity to view these lectures. Mind you, I struggled with QM for years before this, there is so much terrible information out there, even from the physicists, that a layman can become totally confused by it. Lubos Motl, Anton Zeilinger, and Nima are all people who who get QM and can cut through the noise.

      +Shirley Mason Good one! But, in our hearts, we know that what is "broken" by the "collider" is energy. Quantum energy is measured how? Space/Time theory does not explain gravity -- that, as mentioned is "dead". We can discuss the "mass" as the total energy of the body; e.g., the Earth or Moon, and measure the gravity when the electric forces are the unit of measure.

      +Lindsay Forbes Yes, the energy which is transported to the "City" is "Dark", and is only observed when it accomplishes "Work". Ergs, Joules, Watts :) What lights the Milky Way?
      The combined energy of every single atomic particle of our individual existence, along with the mass of the Earth, our Sun and Solar System; combined with the spiraling energy of our "Local Group", join with all the rest of the star systems that are 'lighted' to show the Dark Energy's passage into, and which lights the center of our galaxy. That is the "Power" and the return "Currents" magnetically stabilize the various systems spiraling in those orbits, with all the rest.
      Whatever "Chaos" our system encounters has been encountered untold numbers of times in the past, and will be so in the future that we, "Ants" can conceive ...

    • @new-knowledge8040
      @new-knowledge8040 6 років тому

      OK. Let's start with the basics.
      1) Let's say that we exist within a 4D environment called Space-Time(ST), and that everything within this ST is constantly on the move with a "c" magnitude of motion. Thus if your direction of travel was set to be across space only, rather than being across both space and time, or across just time, your speed would be measured as being the speed of light, aka "c".
      2) We are always confined to the present time, or real time. Thus we are 3D entities. However, we exist within a 4D environment. Laws of physics must also exist outside of our present time, but they would be different from those that we are familiar with, since they would include extension across time. Thus outside of our present time, events would be 4 dimensional.
      Funny enough, if you analyze the outcome of 1 & 2, you end up with 1) Einstein's Special Relativity phenomena, and 2) You end up with all of the strange quantum mechanics effects.

    • @tongmaa
      @tongmaa 6 років тому

      +NEWKNOWLEDGE Well, first we have to define our terms. Let's start with "Space"? What is its definition, in the absence of matter/mass? If "Space" is curved outside of a mass, then what is "Space" composed of that can be curved by the presence of a mass? How did Einstein form the putative "Space/Time Continuum" in a Universe that was empty of all mass (Ric=0)?
      What is "Time" as an entity? "Time" is the *measure* of duration -- and "Duration" is a convenient concept of Human kind, and not an object, like a hammer, per se. Besides that, what "Time" can exist in an empty Universe, and no distance or real process to measure seconds, minutes, hours or any measure of reality with only empty space, and no instrument to tell time ...
      Even in our 3D Universe, there is no "Time", and as you mentioned -- there is only *NOW!* No "4D environment." Funny, about laws-of-physics being "outside" of our *NOW. :)* You must be talking about the *TAO* and that others refer to as *GOD* and about those *LAWS OF OUTSIDE?*
      Remember Pascal's Wager, and stay safe ...!

      El Shaddai means God Almighty in Hebrew
      It comes from the Hebrew word shad which means mountain
      The Arabic word for mountain is sana
      Sana means thread of summer in Japanese
      Sana means eternity in Sanskrit
      The Ancient Jews believed that the earth(cosmos in Greek) was flat
      Albert Einstein modeled the cosmos with an infinite flat sheet of space/time
      A black hole is an infinite pit in space/time
      An infinite mountain in space/time would be an infinite white hole.
      Dark Energy and Dark Matter can be explained by finite quantum spinning white holes(tachyons) that exist for a few planck instances.
      Some scientists believe that the big bang was a white hole
      If God is an infinite white hole than the Father would be the infinite singularity of the white hole, the Son would be the infinite tachyon, and the Holy Spirit would be the infinite tachyonic wave(space)
      Space does not expand: The cosmos is shrinking while space is constant. This means that the speed of light is shrinking each planck instant in a way that makes it appear constant
      If the cosmos is shrinking then the density of energy is increasing.
      This means that all energy will become a black hole because of Schwarzschild radius
      The beginning of the big bang had 0 entropy which means 100% of the universe was light
      The universe now has less than 5% light
      Conclusion the 3 dimensional cosmos is inbetween an infinite infinitely dimensional white hole and an infinite 0 dimensional black hole. (Taegeuk)
      Good does not need evil to exist
      Black Holes are not eternal because of Hawking radiation
      If you don't abide in Jesus Christ you will be deleted
      You have the choice to be loved everlastingly or to suffer infinite entropy as your last memory that seems forever because 0 time is eternal to a tachyon
      Please choose the Perfect Agape of God.

    Nima's best talk currently on UA-cam, for a "primed" general audience, which addresses these fundamental concerns in survey fashion, I think. This address is tighter & leaner, flows better, and fills in some gaps previously left unattended to, again and again (alas), in a way that makes Nima's argument more lucid in practical terms. Much less stuttering about, "um-um-um"-ing, and fewer hand waving gestures, too, than previously typical -- all to the good.
    I'd point others here first if you are recommending Nima to a friend with a good general background knowledge in the physical sciences who might be interested in these topics.
    It's good, too, to see that Nima has apparently managed to stay slimmed down for awhile now. I probably won't be here to get the professor's take on these matters 25-30 years hence, but I feel a bit more optimistic about others getting the chance.

    Interesting man, interesting topic. Capable of explaining very complicated areas of physics so that anyone can sort of understand. It seems like every time I watch one of these lectures when the camera pans out to audience the average age of people attending these kinds lectures has to be at least 60 years old. Personally I'm 62 so I would fit right in age wise at least with the audiences. There is at least one exception to this: Richard Feynman's audiences were very young. This could have something to do with the fact, however, that a lot of his lectures were given to students trying to pass one of his physics courses so perhaps this doesn't really count as an exception. But it makes me wonder why young people are, on average not very interested in physics.

    The phenomenon of resonance is most likely where we will find answers to the most intractable problems.
    Concerning the question of what happened before the Big Bang, there is no known law which prohibits a resonating wave from spontaneously appearing in the quantum soup. In fact, as the quantum soup has no time or space, the spontaneous appearance of a resonance wave in the soup must be expected from shear randomness.

    Okay..... we exists within a 4D environment known as Space-Time, however we are also confined to the "NOW" time, thus we are confined to a mere 3D reality. So you have two realities. One is 3D, and the other is 4D. And on top of that, you obviously end up with two different sets of laws of physics. Take the famous 2 slit light experiment for instance. Which set of laws of physics are in control of the experiment, is what determines whether you will see particle behaviour occur, or wave behaviour. And of course the 4D space-time reality, and its own set of laws of physics, also explains things such the delayed-choice quantum eraser experiment, and its results that were witnessed in 1999.

My other 2 questions were little more technical which i asked him outside the hall & that was about co-relating Quantum spin of a particle to string field theory & how it speculates or explains through feynmann diagram?
      & can spacetime be discrete? LQG is taking that approach to understand Quantum gravity. I didn't want to go too technical & too over the topic but I wasn't too off. Also i wanted him shed some light on Entropy, Spacetime & QM.

    He oversimplifies "quantum tells us there's no determinism" end of story. But quantum just shows us we can't predict a fixed future. It doesn't mean the future is not fixed. Determinism arises from either/and time dilation, or simultaneity in relativity - both point to determinism and don't work without it. It's also not clockwork determinism, it's 4dimensional structure determinism.

    • @LuisAldamiz
      @LuisAldamiz 6 років тому +1

      Chris: but that is a specific theory of physics, not physics as field, Thales is the one to be credited for the development of physics as research of nature in an empirical and non-mythological way. Of course he could have got precursors but they remain unknown. Aristotle himself considered Thales to be "the first philosopher", i.e. what we now call "scientist". His main work was in the fields of geometry and astronomy, conceptualization of causality and ultimate origin (arché). Of course he was a pioneer, so some of his ideas, such as "water" being the principle of it all, sound now weird, loosely magical and obsolete, but so does much of "science" before Descartes.
      Democritus is two centuries more recent than Thales, who lived around 500 BCE, so he should be more advanced, just as Einstein is compared to Newton.

      What do you mean "you don't have the patience for it"? I've been studying quantum stuff for years and I know how to program Quantum Computers... That takes patience - especially when it only is useful for certain kinds of numerical analysis - honestly its a process of data to 3D transformations that the Quantum Computer can handle as data in, then BANG, it gives you enough information to convert it into data forms (data results translated to numbers people and other computers can process) It's really FAST at one thing.... but each Quantum core is really nothing more than a BALL you manipulate and the orientation of them.... Its kind of strange. Like Data to Quantum Computer Usable, Processes in instant, then translate back so you can read the results. It's like useless in video games or simulations unless it's a "HELPER" - quantum computers CAN NOT do what regular computers do... Regular Computers, can not do the ONE THING quantum computers do fast.... calculations on a small quantum sized marble that spins and stuff, transformations - are actually 3D in nature - Quantum seems like 3D programming spheres in a game to rotate and spin and then read their current position when it stops... kinda how works - weird...
      But don't say I don't have patience for it... Particles turn to energy that is still vibrating and acts slightly different - then by being observed it can collapse from energy (still the vibration of whatever material) back to its physical form. Add quantum entanglement... and unified field theory - All this stuff screams "God Created the Universe" not - PER CHANCE. Gambling is bad M'Kay :) And don't worry, I know the Earth is round.

    This is an invitation to see a theory on the nature of time! In this theory we have an emergent uncertain future continuously coming into existence relative to the spontaneous absorption and emission of photon energy. Within such a process the wave particle duality of light and matter in the form of electrons is forming a blank canvas that we can interact with forming the possible into the actual! The future is unfolding with each photon electron coupling or dipole moment relative to the atoms of the periodic table and the individual wavelengths of the electromagnetic spectrum. As part of a universal process of energy exchange that forms the ever changing world of our everyday life the ‘past’ has gone forever. At the smallest scale of this process the ‘past’ is represented by anti-matter annihilation with the symmetry between matter and anti-matter representing the symmetry between the future and the past as the future unfolds photon by photon. In such a theory the mathematics of quantum mechanics represents the physics of ‘time’ with the classical physics of Newton representing processes over a period of time, as in Newton’s differential equations. In my videos I explain how this process is relative to temperature and the phase changes of matter.
