3:20 the interesting result here is that you gave your computer cool eyes :D

Quantum theory and General Relativity have been perfectly aligned since 1981... Universe Expansion As for expansion itself, there is a temperature based 2 directional tensor on every particle we have ever observed from plasma photons, up to any atomic weight we have encountered so far. If you consider a deeper weight particle lives at an interference point and is constantly being fed expressed heat from it's immediately (doubled depth and distance) deeper particle, or from ambient temperature at its' depth in the weight space. The deepest particle interferes a new weight and goes the summed interfered temperature C^3 or degree Celsius deeper in its' weight space, the internal "Cavendish" tensors from the particle depth SR monodimensional BB space, pulls the particle back "up" the temperature scale. The particle will shed two "half temperature" photons back up the atomic pipe causing interference in the half distance position of the atomic pipe and the same thing happens at that temperature scale, all the way back to the aperture of the atom and being expressed as a zero degree Celsius photon particle (No velocity at all). If you consider the temperature over distance equation, and add in the redshift of the exhibited photons you realise that the redshift of a "stable" atom by definition on the C^3 scale has to achieve a temperature of zero degrees Celsius as it finds its' position in the "visible space". So instead of the stacked atom we observe, we actually have a redshifted temperature pipet from the Big Bang , too our visible space, which is expressing a Big Bang instantaneous explosive energy at Zero Degrees Celsius and Zero Velocity! This is our visible aperture of space, and it (the Universe) simply started growing when the expression of the BB in its' GR'd observable frame of reference (i.e. expanding at C) , a C velocity time dilated by its' temperature and redshifted by the decreasing to zero degrees aperture space allowing zero degree Celsius photons to "simply appear" in our space, expanding our Universe one photon at a time multiplied the the "Skin Depth Aperture" of our observed universe. Atomic particle formation, is the other side of the BB energy cycle through our space, which means the atoms are slowly in comparison "swallowing" photons that are too hot for the zero degree space and their journey back to the Big Bang has started. When you consider the amount of matter that we observed versus the amount of empty space, it's easy to see why we are still expanding, and likely will continue to do so forever. I have read Stephen Hawkings' paper "Properties of an Expanding Universe" and everything he postulates and describes fits in to the above theory. (C) M.B.Eringa; S Hawking; G Dalton; 1989;

Postulate 1. Light is an ordered vibration of gravitational quanta. Postulate 2. The gravitational field controls the frequency and speed of light in a vacuum.

You should be thinking of the layers BEYOND, as we are talking about the largest scale in the universe, the universe itself. At least that was the goal of everything, modelling the 4-dimensional universe(from which gravity should naturally emerge in correct ratios). For that they needed quantum mechanics - the influence of the smallest on the largest.

Guys am not a physicist but am interested in science! (physics) this very morning as i was looking to this video learned something that..... "Time is nothing but movement of every individual particle in space at quantum level at perfect interval, and its very difficult to capture time because it is moving continuously without stoping and the one who wants to capture time, his body , equipments and surrounding particles, are arleady in movement , in that case may accelerate to an error, thus in order to affect time one, have to affect the particle at quantum level, forexample spinning the particles at high velocity time would seems to slow example car wheel at high speed seem to sloow down in movement" this idea came as i imagined how the "sand timer" worked on those days..tell me guys what do you think.😅😅😅

Any physical force is a hydrodynamic effect, within weightless matter, arising from the interference of physical fields. And it always implies the existence of the distinction of movement, as direction, intensity or meaning. Gravity is a physical force, because it is born from the interference of gravitational fields with opposite directions. The interference that creates the depression in space, in which the bodies slide. Because all bodies slide where the pressure is lower.

Very interesting about CDT. I would love to take some courses.

My personal understanding of the connection between quantum gravity and general relativity, is that maybe; spacetime down there is characterized by completely different metrics than the Minkowski and Schwarzschild metrics (and others) that describe general relativity macroscopically. Meaning that many things that are forbidden in the theory of relativity, could be allowed(?) down there in the quantum level due to the nature of the spacetime down there; So maybe we can have faster than light particles or even particles that travel backwards in time, things that might explain the weird phenomena observed in the theory of quantum mechanics; I don't know if this idea is correct, its just my intuition.

I don't know if I got it right, but I think that the difference is that they managed to come up with a model with very few assumptions, unlike string theory for example. So they seem to have an "Occam's razor valid" model, which is a great step forward as it doesn't rely on non-existent data. That's why she said her research is moving towards describing the early universe, if the model can describe relativistic cosmological observations (from a "simple" quantum gravity model), then she could claim to have bridged the gap between general relativity and quantum mechanics. Which could be validated with further predictions and observations. But for now, it's just a promising mathematical model.

To my mind, it looks like a formula for computer graphics

Skin Theory - The Higgs temperature mechanism General Relativity: TDR = (Temp/5)^2 seconds (+1c^3 == +1ºC) Temperature is an aperture to BB weight/temperature, the larger the aperture the higher the temperature, so ... Pi*12Planck^2 == +1c^3 == +1ºC But, The ligo experiment demands the aperture stay the same and the underlying energy density doubles so ... Energy Density = Particle Count / (4/3*Pi*12Planck^3) A Ligo style interfered Higgs Reaction would be described as ... ED = 2*(Particle Count) / (4/3*Pi*12Planck^3) So we get +1ED == +1c^3 == +1ºC So aperture temperature and size are directly proportional to the "Photonium" particle count per cubic. Halve the ED and the photon rises towards our visible space (Entropic Expansion). Double the ED and the photon drops away from our visible space towards the BB hyper space (Entropic Collapse). Energy Density is directly proportional to the Skin compression if the particle is stable. M.B.Eringa, S Hawking 1971~Jul 2022 PS: There is an implication that the interface angle between our visible space and the BB space is always 90º regardless of Visible space orientation / polarity. PS: The exhibited temperature is 1/2 single laser temp for twice as long, because the stable particle skin doubles, halving the the input temps back to a single laser temp (Stable) and the distance into the BB temperature space halves the temperature again, the twice as long is to satisfy energy conservation rules.

October it is then. Time to flip some tables, q is a great space to play in. It's interesting that in English it always is followed by a U Just like there's 1m ways to skin a Cat. So to is there 1m ways to describe the same thing using different terms.

Skin Theory - The Higgs velocity mechanism General Relativity: TDR = (Temp/5)^2 seconds (+1c^3 == +1ºC) Lorentz Gamma: TDR = V/c (Result in Degrees Celsius) Higgs Velocity TDR = ((v/c)+5)^2 ... So for the Muon G2 result we have ... +3x10^8m/s == +1c^3 == +1ºC Which implies Zero Degree Celsius space has a stationary in situ energy potential = At least the Speed of light (i.e. A distance to the the zero line of the BB space). 1c from our 3d space potential. 1c from the Velocity addition over c of the collision (**Into the BB weight space??). 1c from the depth into the BB weight space temperature aperture. (Causes a dowel like flow of space towards the Big Bang aperture binding the two space connection open) This implies the exhibited temperature should be half input temperature because of BB space redshift (**a c^3 additive superimposed distance??). M.B.Eringa, DrDon 1998~Jul 2022 PS: There is an implication that the interface angle between our visible space and the BB space is always 90º regardless of Visible space vector direction!. References: DrDon; Garret; Stephen Hawking; PPS: Garret and myself have long been discussing the top of the C^3 weight space scale. Based on the Higgs velocity mechanism, I am thinking that the scale above the zero line on the atomic scale (i.e. our 3d space side) should be in 1c increments until the zero line and then swap to 1c,1c^2 and 1c^3 increments below the zero line. (i.e. +1c==+1ºC for speeds up to the speed of light) The tricky thing is, the zero line is the top of the c scale, and our 3d spaces' zero line is its' weight temperature back from that zero line, so the scale should actually look like the below for a plutonium proton... + 0c + 1c ... + 20,000c + 0c^3 + 1c^3 .... + 20,000c^3 The magnetic aperture starts at the BB space but the spacial flow "dowel" needs to go the same c distance back into our space, although it likely will collapse into a 3 dimensional sphere afterwards, the magnitude still needs to be represented on the diagram using the c scale.

Please don't tell me that space time is a triangle tessellation, I am freaking out about the Simulation Hypothesis enough as it is.

The Big Bang If we assume all natural matter is grown using photon interference this means all atoms/photons and indeed the big bang itself has to be exactly the same volume, otherwise the temperature would not double and unnatural atomic structures would grow. So the big bang stats as I know them ... Diameter: One Photon (12 Planck). Using Energy over Volume until 10^18°K this is about 8.94713*10^-7Meters if the photon is 3°K . Using Inverse square until 10^18°K it would be 1.74*10^-9Meters if the photon is 3°K . Lightest/Lowest visible temperature: 10^18°C (This is the first Harmonic. i.e. electron weight BB temperature or Photonium temperature) Heaviest/Highest harmonic temperature: 10^144°C (This is the fourth harmonic based on atomic structure i.e. deepest neutron BB temperature) Time for the Big Bang to stabilize(Half its' temperature): (10^144/5)^2 =1.2710033300287246752586491776608e+279 years Hyper-dimensional Distance of deepest weight: 10^144*C^3 (**Velocity Higgs Mechanism contradicts this!!) Actual atomic distance of deepest weight: 40C^3 Giving us a maximum temperature based BB G Constant of 40/10^144=4E-143 (No Cavendish Modification) And a first harmonic G constant of 40/10^18=4E-17 (No Cavendish Modification) If the BB is spinning, then frame grabbing of the entire atomic structure will exhibit the universal chirality that is observed. It also means the entanglement exhibited by electrons is likely directly linked to the space that is feeding the particle and is related to time-dilation, so the theory is incomplete, the spin angle/state of 720° will likely reset after the electrons time dilation "expires" for any given spin angle, for an electron this would be 1 second. If all particles are the same size, this means any differences between Fermions and Bosons has to be temperature which is directly proportional to weight, remember all these particles exist in a hyper-dimensional space and we "see" the hole doing "down" to them. We also have a new number to find :-) ... Considering what we now know about the GR Zero°C space that the atomic hyper-window lives on, there must be a GR/Volume temperature that we have until now not known existed this will be either a Photonium particle count by volume or a simple temperature per volume, and is directly related to the number of planks between our current visible Universe and the BB (The Plancks between us have recently doubled, which implies this temperature has also doubled). I postulate this is the spacial compression tensor holding the hyper-window aperture "Open" B-), it also relates to entropic expansion and collapse algorithms. I.E. ºC/(M^3)=Observed 0ºC; /* M will likely be proportional to the number of Plancks between us and the BB. */

When Renata says @4:25 "it is not a given at all" I think she is a bit loose with her language. Anything that comes out of a model is a given, by definition. What is not "a given" is that the model is correct, and that remains unclear for CDT. "Looks like a 4D object" is all in the model. The fact the physicist programming the model has no clear *_a priori_* idea what their model will predict or generate is par for the course. It's not a revelation a non-linear model can surprise the modeller. This is also the whole story of current ANN's.

This is one approach I've been thinking for a long time. Some interesting ideas that could lead to new insights for the future of Q.Gravity : simulation of gravity phenomena instead of direct results, background independence, information fields: spacetime and also matter as the product of information fields, notions of singularity and time in this picture ... and many more puzzling features that need to be studied, adjusted, and combined for a legit theory of quantum gravity.

Quantum WHAT?!

I wrote a science fiction novel in 2016 in which the basic premise was that the two main characters use a theory of quantum gravity to produce a virtual reality that's as convincing as reality. Really interesting stuff. The quantum gravity theory they use in the novel is one of my own devising, though I think it's closer to Felix Finster's idea of causal fermion systems than any other idea. The idea was that spacetime is formed of a background of tunneling electrons that constantly exchange bosons with other fermions. So, for instance, the cosmological constant would be the result of photons being emitted by this background of tunneling particles. No one agrees with me though.

These may be negatively charged, and a positively charged probability cloud will also reside in the center of stars, planets, galaxies or galaxy clusters. Ordinary matter will accelerate towards lower potentials due to electrostatic forces due to the presence of the exponentially larger probability clouds they are in. The probability clouds themselves will accelerate towards lower potentials of even larger probability clouds they are in as well due to electrostatic forces and carry ordinary matter along with them. I have been trying to get so many scientists to listen to me, but it is a losing battle. We seem as if we want to be stuck in not knowing. I have been rejected by three journals already. There is no better theory yet, and no one is willing to even look at what I am proposing.

Quantum Gravity should be the correct explanation for gravity while Einsteins theory would be the limit of Quantum Gravity. Arithmetic vs Calculus

3:21 The Universe is made of croissants, got it.

Gravity is a simple side effect of galactic mechanics. Try not to get caught up in all the weirdness and complexity of reality while you search for the fundamental truth.

U kno, instead of quantum gravity, why don't anyone go for a general relativity theory of quantum fields? A better way to put it might be "a space-time theory of quantum fields". The former approach has went nowhere for the last 50 (or 100?) years. Isn't this time people try the opposite way? Why such a hangover with quantum gravity despite it failing for generations.

These sorts of things are always entertaining. What part of "gravity is not a force" seems to confuse scientists? ;) Spacetime is a field of potential energy from which all other fields derive their energy. Or, in other words, the total energy at every point is a constant. That's really all you need to explain everything. Well, that and waves, of course. There are no infinities. There are no singularities. There are no contradictions.

Publish it then! It's not so much about having an intuitive grasp of how the universe works, but to have a rigorous and reliable model that can be used to develop further research and applications. If you can't translate your understanding of the universe into mathematical formulas (or other equally useful expressions), then that knowledge is useless.

@@nachoijp No knowledge is useless. What is there to publish? It's just a broader application of KE + PE = C. Proper time adds a huge wrinkle because of its imaginary nature causing Euclidean space to become hyperbolic spacetime, but that's already well understood.

Will string theory win?

Hello from Kazakhstan. The Dark Universe requires a lot of money from the budget: an experiment that sheds new light on the Universe will help save costs. We can create an educational and practical device and practically master Einstein’s theories of relativity or obtain, for example, new physics: Postulate 1. Light is an ordered vibration of gravitational quanta. Postulate 2. The gravitational field controls the frequency and speed of light in a vacuum. This is determined experimentally using a hybrid fiber optic gyroscope (based on Michelson's experiment 1881-2015). Using a hybrid fiber optic gyroscope, the straight-line speed of vehicles can be measured. There is a company in China that makes (fiber optic angular velocity meter) they will be able to create a hybrid device. Please, can you come to an agreement with them? I guarantee payment at cost on my part.

I am not a Physicist but I have an idea that the friction we suffer, which makes our time curve, would be responsible for the forrmation of dark matter or dark energy that goes to the black hole increasing the negativity of it, acting parallelly (like entanglement). The mass of a celestial body, if considered a lot of matter together, result of some friction (contact), would make difference on how much negativity (attractiveness) a celestial body has, being able to be felt in the vicinities of this celestial body which, the biggest the greater the negativity (many call it gravity). P.S.: I also consider the fabric of space-time to be true.

I have no clue what you are saying, but I will say that the words "I am not a Physicist" should indicate to both you and I that perhaps you don't know the intricacies of these topics enough to actually pose any coherent ideas about them. As these advanced physics topics are often presented for the public, I think they seem a lot fuzzier than they are. They are very grounded and mathematical, it's not just a "well maybe friction of space time *insert more jumbo jumbo*".

i find this approach incredibly dull and naive, but exploring all the options is important

Very similar shapes have appeared to me while exploring possible alternatives to the 'dark stuff' fiasco. To simply give the error a name; 'dark matter', and then naming the remaining error 'dark energy', well, it's embarrassing. Brace yourself for 'dark antimatter'.

If the theory breaks down at any point, it is incomplete. GR breaks down in 2 critical places, it is incomplete. There is obviously a next step, I think if we hadn't spent so much time focused on where GR does work and so little on where it doesn't; we would've covered those next steps.

She’s onto to something, to be sure. But anytime these yahoos go on to synthesize new words, I think they’ve run out of steam from thinking too much like a free radical.

This was a trailer for CDT. Quanta needs to do a better job editing their videos to make it compressible rather than just exciting and seemingly doing the opposite by pumping it full of loosely connected clips and upbeat music. After watching this video I had no idea what CDT was and had to google it for a basic explanation.

Quanta isn't for understanding from scratch. Its scientific journalism intended to convey what is happening on the bleeding edge of science to the masses. That goal can only be accomplished if they communicate the scope of the discovery and not everything underlying it. You were interested to learn about CDT, so you did online. Quanta is not an educational platform
