String theory vs Loop quantum gravity: Wild hunt for Quantum Gravity:

[@ArvinAsh]

Guys...let me know what you think of the sound on this video. We tried some new sounds and sound engineering on here. I would appreciate your honest feedback. Love it, like it, don't like it, hate it? Your constructive criticism is helpful, so we can continue to improve on future videos. Thank you.

[@user-wu8yq1rb9t]

Sounds just was great and Cristal clearly for me. In this video, the music was more clearly than the other videos. Especially in the middle of the video, music actually touched me (I wanted to say it, even before you asked. I thought it's just for me. But you said that you try to improve the sounds).

Thoroughly enjoy watching your videos and really appreciate your clear/concise explanations. I feel it has the right amount of detail so as to not overwhelm the non physics major yet enough of it for someone who would be interested in learning about the very universe we're living in.

[@autosapien1]

Hi Arvin, I strongly disliked the music on this video, it made the explanations much more difficult to understand as I was focussing on the music rather than your voice. Please remove the background music completely, I can't understand why you would think it adds anything to the video as it's very distracting. The content, script and animations of the video were excellent as always.

[@JoshPillault]

Lmao, I typed in “Einstein gravitational theory” and found your video on it, was blown away and watched it multiple times and had utterly mind-blowing epiphanies at having it explained so clearly. By the end of the video you had me dying to know more about Quantum Gravity - but I suddenly remembered string theory, something I’d heard about years ago, and wanted to see if the two were connected. Typed in “quantum gravity string theory,” clicked the first result, heard your voice, clicked subscribe. Hell yeah man. This is gonna be awesome.

[@arandomguy4614]

I think advanced research on black holes can provide us with some solid evidences of either of the two theories. The amount of gravitational fluctuations around primordial black holes is massive and these fluctuations can unfold major secrets. The gravitational fluctuations can be detected as disturbances in the speed of light which can unveil something about Loop Quantum Gravity. On the other hand the space around the singularity can provide us something interesting about string theory. Let's hope we unravel this mystery soon.

Source Anuj: time dilation cannot affect things which are constant at everywhere means a thing which doesn't move it instantly spreads everywhere to the infinity.So if we take two sand clocks set together at the same time at the same place . And then one clock put at 1km distance from point 'P' and another at 1metre from point 'P' a light is swithed on at point p at 12:00 noon then if light is constant not having any velocity, then when light reaches both clock the same amount of sand would have falled . Otherwise, if light has velocity not a constant object , then both clocks have different sand falled in amount when light reaches them

[@nicogubernari3293]

I'm a researcher (in particle physics) and I think your video is extremely well done. I'm not sure though how much a non-expert in physics would understand ;). One comment about the part of the video where you argue which one between QM and GR is incomplete. This part is a bit misleading, since GR is a theory while QM is a broader concept which comprehend several theories (classical QM, SM of particles,...). I understand that this is not easy to explain in 15 min, but I would simply say that both approaches are incomplete and they need to be unified. Keep doing your amazing videos! Best wishes, NG

At uni, I came up with the postulate that the expansion is not universal but happens in discreet areas. Like bubbles of space expanding. Thay would mean they collide and the colliding parts would have different relative speeds. If the relative speeds reach certain %ages of the speed of light, the place where the "collision" occurs will be subject to time dilation and space contraction. I.e. tiny, "permanent" areas of space will manifest. We interact with these as "particles". So, a particle is actually just a part of space that exists on a different level to the rest of space. This explains why things appear "quantised". If you look at deep-seated images, you can see galaxies form at the edges of voids of space. Just an idea. I was never good enough at the math to calculate spherical and vortex phenomena in actual equations.

[@hikmetullahcevik7123]

[@Dragrath1]

String theory 's dependence on supersymmetry and the inapplicable cosmological constant are big problems but one more worrying aspect is the way they have attempted to add correction terms for each failed prediction. While we can't easily say when it is time to give up on a hypothesis or model it needs to be noted that Fourier analysis says any model with enough correction terms can match any solution so adding correction terms while it may work should be avoided as much as possible less we get a repeat of epicycles. The simplest model or rather perspective model as I mentioned last time is whatever framework emerges out of wolframs turning machine empirical rules which at least in the limiting case of a sufficiently large amount of data for a turning machine to iterate on seems to spit out vacuum solutions for general relativity and the Feynman path integral bot formulated in terms of the Einstein field equations. I would keep an eye on what potential testable predictions or how some of its potential insights might be used to develop new models of physics. In particular time there appears to act as a generator of space based on the relations of elements of the large array which seems more in line with Carlo Rovelli's ideas if in a more computational context and the different origins for the phase and amplitude of the wave function suggests a little bit of de Broglie& Bohm's pilot wave theory might have basis while the finite speed of entanglement required by the emergent mathematical formulation requires there to be a large but finite constant speed of entanglement and an associated entanglement cone in analogy to the light cone of physical space. The model also helps offer potential resolutions to several quantum mechanical oddities or problems (i.e. many worlds) with the existence of a separate entanglement event horizon preventing or avoiding information loss. I doubt it is entirely correct usually by the time consensus arises with evidence to back it up things tend to more complicated than the simplest model but not much so

As always, an excellent video, Arvin. It's time to start formulating a theory of gravitation, in which mattergy (Mg) displaces spacetime (ST). Here, Mg and ST are both seen as possessing mass and density---with Mg as possessing more and ST less. This allows Mg particles, forces, and fields to displace those of ST. Further, a force within ST, akin to the EM and strong forces, acts to pull any displaced ST components back together to close such displacements. Finally, the continuous pushing out of ST by Mg and pulling inward of ST by a sort-of integrity-field would be felt as "gravitation." Maybe you can do that.

That it’s quantized sounds correct, but if mass is added to the underlying quantized areas then that quanta has to be updated to reflect the new energy levels - so something with no mass like a photon is updated immediately but a large lump of mass like Jupiter takes time for the “accounting” to be done across all these quantized areas, and thus “time slows down” whilst the speed of light remains constant. The leftover part of the mass that is still in one place and has its copy in the new node locations before being deleted from its previous location is now your dark energy that you can’t see. It’s kinda like banking - you send your overseas friend some money and the nostro/vostro accounts are invisible to you, but that doesn’t mean they are not there behind the scenes. Lastly, if you unloop the quantized space, and move to a more “loosely sprung chicken wire” model, we can postulate that gravity pulls the energised nodes closer together and thus the slack this creates is the force pushing galaxies apart.

Explaining what is still not known is very powerful information. With all those layered fields, we don't know if one or more of them predated the big bang and was overlain.

will you please make a video on how sub-atomic particle is made up of vibrating strings with some animated visualisation.And more importantly thanks for the informative videos.

Can you check this reasoning for errors please? 1. Gravity is not a force but spacetime curvature 2. Curvature leads to time dilation, so the electrons of an atom in a gravitational field 'spend more time' on the side of the atom facing away from the centre of gravity. This deforms the shape of the electron orbitals. 3. When squeezing a balloon (or orbital), the balloon pushes back on your fingers with a force proportional to the elasticity of the material the balloon is made of. 4. The force pushing the atom towards the centre of gravity is the resistance to the deformation of the electron orbitals and thus is electromagnetic in nature. The force carrying particle for gravity is a photon. You may need to swap the EM-field for the gluon field but the same principle applies. This could explain why gravity is so weak compared to the other forces.

Amazing summary. Keep up the good work!

[@scudder991]

Excellent summary of both theories! Thank you Arvin!

Great to see the channel grow and the audio is better I'd say.
