There is likely a deep connection between the study of quantum foundations on the one hand, and the much sought after quantum theory of gravity on the other. Despite the enormous success of quantum theory, there are issues in our understanding of the theory, which need addressing. These include: the nature of the quantum to classical transition, the peculiar nature of quantum non-locality, the problem of time in quantum theory, the extreme dependence of the theory on its own classical limit, and the physical meaning of the wave function. Could it be that addressing these issues requires us to reformulate / modify quantum theory, in such a way that we get rid of the theory's dependence on its own limit, and on classical space-time? If that is the case, then introducing non-classical space-time in quantum theory naturally leads us to a falsifiable quantum theory of gravity. This is the viewpoint developed in the ongoing video lecture series `Thinking about Quantum Gravity'. The lectures are addressed to those undergraduate and graduate students in physics who would like to research in quantum gravity. It is not expected that the viewer will agree with everything that is said in these lectures. Rather, it is hoped that you will find something to think about, as you develop your own thinking towards quantum gravity.

That is the address for "Where in the World are SUSY & WIMPS? - Nima Arkani-Hamed" I don't know if it has any relevance to Tejinder's video series. It sounds like the presenter is in a great hurry to present his material. (Confirmed at the end as not wanting to miss lunch). Seems to be about the standard model and suggested solutions to problems with the theory. The Hierarchy problem, the problem of fine tuning mentioned. Got half way then skipped to the end for any takeaway conclusions. Comparing volume of Earth to volume of Hubble ( I presume the supposed volume relating to what can be generated from input received by the Hubble telescope. And is asking if a God's eye view even makes sense. Left wondering why the video was suggested. What did you want to draw our attention to Wahed?

Forgive me for jumping forward to this video as it seems particularly interesting to me. I intend to watch the earlier ones. I have got as far as the circularity issue. Is t in the equation really a part of space-time? As I see it space-time is a product of observation and the evolution of the system prior to measurement does not require being part of an observer's experience. Is classical space-time produced by classical bodies? Types that can be observer's generating a product but not any body. A body's motion can lead to conditions that bend EM radiation paths but that alone is not generating space-time. It requires input of that EM radiation to a system that generates from it the space-time product. Are classical bodies a limiting case of quantum theory? An observation product in seen space-time is not what is evolving in the pre-observation system.

On the page "Could Consciousness Forge the Universe? I have introduced the terms 'pluripotent' and 'multipotent' to refer to beables, firstly in their 'wild condition' no orientation or context of observation applied and the second term referring to a beable considered with constraint or limitation of possible measured outcome states because of the selected view point and /or method to be applied. These consideration of beables are different from a singular limited, partial view of an object formed into a seen image manifestation. Not only is this dealing with the circularity issue but it suggests that 'many worlds' pertains to the potential of the multiipotent beables considered pre-observation and not fracturing of reality into many alternate worlds comprising all observations (known by a singular observer to have been made and not made) upon observation.

Hi Tejinder I have now watched video 5. Thank you for so clearly setting out the issues. From my previous posts it can be understood that the pluripotent and multipotetnt beables that I mentioned are not classical objects in space-time.There is a categorization error in special relativity, a lack of differentiation between the existing and the seen or observed. Space-time pertains to observations, products generated from received signals not existing outside of the observers.So it is an error to imagine space-time as an independently existing manifold (over which the classical metric is overlaid to get a physical explanation of the space-time points.) The space-time is not the dwelling place of material things. Level 1 would be the existing configuration of the universe of all beables. Each configuration being a time and only the youngest existing.

Video 6: Very clearly explains the issues again. I like the pace. My own thoughts on the double slit experiment: The physics involving the particle and its environment is happening in the unseen universe of beables, not in seen space-time. Agreeing on a level 1 but not exactly agreeing on what that level is. The nature and motion of the particle affects the ubiquitous environment around it. Unseen waves generated in it pass through both slits and their interference affects the path taken by the particle beyond the barrier. The 'ubiquitous environment' does not provide sensory data that can be processed into knowledge about it. So it is not a part of the observer's experienced reality.Yet the experimental results imply its presence outside of experience In the beable universe, rather than the products of sensory processing, the vacuum is not empty but filled.

Another very clearly explained talk, about wave function collapse. My own thoughts; There is a switching of what is being considered. From thinking about a superposition (related to a multipotent beable particle or phenomenon) to considering the limited, fixed, singular outcome state. Which is not a beable but a measurement state or value. It feels like slight of hand. We don't see macroscopic superposition (the pluropotentt or multipotent condition) because seeing is itself a kind of measurement. Potential sensory information (EM radiation) emanating from the object is used in generating a limited, singular observer view. It is not because the pluripotent and multipotent objects are short lived. They are the wild and constrained normal condition of beables. We don't see beables (actualizations). We see manifestations that are observation products.

It seems to me it is the method, which can include exposure to apparatus, that is limiting the outcome that can be obtained to a singular, fixed state outcome, starting with a beable that is under the chosen method multipotent. Re.resolution of Schrodinger's cat 'issue'; Recognizing it is a bad analogy involving distinct beable objects that are not different states of the same object is needed by physics. With uni-temporal sequential evolution of the configuration of all beables they (decayed and un-decayed atom, shards and intact flask, dead and alive cat) can not be simultaneously in the same configuration. Unlike eg. black and ginger cat or heads tails coin. Similarly left and right pointing of the spin state indicator must belong to different beable configurations (different uni-temporal Nows) and cannot be in superposition (pluri- or multipotent ).

Tejinder, you offer a black and white choice when you ask "what is right QM or spontaneous collapse?" There is the option of neither being quite right. Seems to me the 'collapse' has something to do with the particle itself and its own evolution (under the particular environmental conditions). Though also to do with the the observation by the observer, that is the switching from considering all allowable possibilities to knowing the singular fixed state measurement outcome. Both related to a named beable but categorically different from it and each other.The starting condition modeled has something to do with the multipotent condition of the beable at the outset, but is not the beable. The state found is not the beable object either but to do with how it is known to us, indication of an aspect of it, subsequent to its exposure to the chosen method.

I just mean eg. heads and tails is not a coin and nor is heads up or tails up a coin. But the beable coin ( an example of a multipotent beable) encompasses both outcome possibilities and can produce singular measurement states.

A thought intrigues me ….It is important to differenciate even if we have the waves particles duality.Must we consider that waves imply all like matters and Energy and space time or the opposite that particles imply waves ,geometries, toplogies, matters and energies …..It is a subtil difference when we consider the waves like primordial informations or particles.Personally I have chosen the particles.The geometries, topologies, matters, properties , waves…..are created due to main codes Inside the particles.That said they oscillate and are waves also

After all if we want to unify G c and h , the general relativity with the quantum gravitation, we must insert the sphères and their motions and oscillations and also the dark matter and quantum BHs in our quantum series Simply.The geometrodynamics are with sphères and their morphisms.The loop is well like others works about geometrical algebras but we need to insert these sphères and their motions and oscillations.They turn so they are :)

Planck is one of my favorite thinkers.He saw the generality of our universe.All his works are so relevant like his équations.He has like you know generalised the wave particle duality with many proportions correlated with his constant h.We can calculate many things with the reduced constant(the lenght of planck,the Density,the mass,the time,the temperature,the charges,the force,the Energy Always of planck,the power,the quantity of movement,the frequence,the pression,the current,the voltage,the impedance,the mechanic impedance.All these équations are so relevant.Now let's analyse the whole and we see that the rotation is essential if we consider the angular moment.We have a hamiltonian,and if we take a particule and its quantic phase and Apply a rotation on the complex plan,we can link with the frequence and the kinetic Energy.Now considering quantum sphères,we have probably an important link between the rotations and oscillations of spherical volumes,the volumes so are very impôrtant and must be in logic considered for a better understanding of all this puzzle.The spherical volumes and their properties could be ranked.If we have rotations and angular moment and fréquences,so we must consider these volumes also like an essential parameter,several proportions could appear.

If this aether is gravitational and correlated with this dark Energy,the cosmological constant,we can extrapolate and link with the Energy of vacuum.

The Energy is enormous.That implies that we must consider this vacuum which is this aether like a parameter with gravitation and electromagnetism implying stability gravitational of matters.We must in logic superimpose these two others main parameters,gravitation and vacuum completing electromagnetism implying stability of matters to our standard model ….more correlated with quantum gravitation this dark matter perhaps also considering that this matter is also encoded in nuclei.Electromagnetism do not seem sufficient,we must add these parameters logically.

Even for the quarks gluons, the glueballs we can consider these parameters Added to our standard model in yang mills theories.More the spherical volumes correlated with angular Momentum and oscillations and ranking of these proportions and diversities.

I have made an error with my equation, I cannot consider the mass ,so I have Simply changed E=mc²+l² but it seems that l² alone is not sufficient considering this Dark matter encoded in nuclei.Others parameters probably are necessary,thats said it is important considering this Energy.The real question is how to check these particles non baryonic,l² is their velocities but there are other parameters to insert.

Lie groups and the S3 seem the method to insert this dark matter, the spherical volumes being the keys,but what is the method for this dark matter encoded in nuclei, if this matter solves this quantum gravitation ,so we can find this SU(qg) for this quantum gravitation.We can also improve farer than nuclear forces in inserting quantum BHs and we have SU(4) and we can insert my equation E=mc²+l²
