Claudia de Rham: The search for quantum gravity

[@durhamgrigg3125]

Thank you both for such a helpful and informative interview/discussion about Gravity. I love Claudia's student's version of a Graviton!! It certainly brings them to life for me!!

Syntax is dual to semantics -- languages or communication. If mathematics is a language then it is dual, classical and quantum physics both use numbers. Real is dual to imaginary -- complex numbers are dual. All numbers fall within the complex plane hence all numbers are dual. The integers are self dual as they are their own conjugates. Vectors (contravariant) are dual to co-vectors (covariant) -- dual bases -- Riemann geometry is dual. Positive curvature (convergence, syntropy) is dual to negative curvature (divergence, entropy) -- curvature is dual. Negative pressure or repulsive gravity is negative curvature or hyperbolic space -- Dark energy. Attraction (sympathy) is dual to repulsion (antipathy), stretch is dual to squeeze, push is dual to pull -- forces are dual. Action (thesis) is dual to reaction (anti-thesis) -- Sir Isaac Newton or Hegelian dialectic on the duality of force. All forces are dual. "Always two there are" -- Yoda. Classical reality (physics) is dual to quantum reality synthesizes true reality -- Roger Penrose using the Hegelian dialectic. AdS is dual to CFT. Two sides of the same coin:- heads to dual to tails, classical is dual to quantum or quantum gravity!

Some have concluded there is no graviton, gravity is an emergent property of quantum effects, hence why no graviton has been discovered. It's well beyond my pay grade to know if that's correct or not, but there it is. I do know that due to gravity being so weak, detecting a graviton, if they exist, will be very difficult.

[@whipple29wrath-inc.58]

@willbrink thay have done this but it's week and the energy needed to measure any further would take a black hole

[@whipple29wrath-inc.58]

Think they watched a cosmic event and measure the dip in a lazers light or something like that and detected the gravitational waves. Way more complex than my simple recollection of it

the graviton is a mental invention of some quantum mechanics pure science fiction on which to make a career nothing Galilean

thank you - very inspiring

You make me happy. In this world of manmade madness...there are people who listen to each other...

[@carlorossi2788]

Excuse me in Italy, the homeland of Galileo Galilei, it is well known that "you measure the effects, not the real world!" this is the foundation of science otherwise we are talking about nothing....

Start with the anti gravity chair party trick where four people pick up a man sitting on a chair.Then check for any weight loss and measure for any fields around the experiment.Then check the second Allende letter in the Philadelphia experiment for the reaction of aluminuim to the vector magnetic potential.

GRAVITY TEST: (Short Version): Direct a high powered laser 90 degrees through an electric field and magnetic field polarized as such to nullify the 'em' of the laser. "IF" my current TOE idea is correct, a gravitational black hole would become evident. (The 'gem' photon being the energy unit of this universe that makes up everything else in existence in this existence.)

[@whipple29wrath-inc.58]

Could gravitational lensing help measure gravity and could gravity be a form of energy if so what end of the spectrum seems everything quantum is energetic.

[@charlesbrightman4237]

For those who claim matter warps the fabric of spacetime, I ask: a. What exactly is 'space' and how exactly does space warp? b. What exactly is 'time' and how exactly does time warp?

[@whipple29wrath-inc.58]

@charlesbrightman4237 time is just a measurement of decay in my opinion it probably 7doesn't exist in the way we think it dose but guess it's still relative lol. The warping of space can be inferred I wouldn't be surprised if gravity was just that space warped around a mass but I'm no professor

[@charlesbrightman4237]

@@whipple29wrath-inc.58 Well, consider 'speed' and the 'speed of light'. 'Speed' is distance divided by time, distance being 2 points in space with space between those 2 points. "IF" space and/or time did not have some sort of actual existence, then 'speed' and the 'speed of light' could not exist except for as concepts alone, which would put a major kink in a lot of physics formulas. Plus, next time someone is pulled over by the police for speeding, tell the officer they were not speeding because time does not actually exist, therefore speed does not actually exist, therefore they were not speeding. See how that works out for them. (Repeatable experiment).

She’s correct - nail:head: first fifteen seconds - because spacetime isn’t fundamental but dependant on ‘motion’… …hence why you get a Higgs field solving the initial matterless state of the universe, allowing mass to transform energy into matter. Chicken-egg paradox of gravity solved there. Bonus: maximum entropy = motionless matter = cessation of spacetime (dependant on motion: of matter)… …no space, in an instant = all that potential ‘energy’ getting ‘compressed’… …simply via ‘subtraction’ of spacetime. Gotta love the simplicity of it, the complexity occurs somewhere in between minimum & maximum entropic states: matter & energy creating life, life creating ‘information’… …this is why I have a low tolerance for evil.

IN THE INTEREST OF FINDING THE THEORY OF EVERYTHING: It seems to me that ANY theory of everything idea should be able to answer the below items in a logical, coherent, inter-related way. If that idea does not, then is it truly a theory of everything? a. Numbers: Modern science does not even know how numbers and certain mathematical constants exist for math to do what math does. Surely the very nature of reality has to allow numbers and mathematical constants to actually exist for math to do what math does in this existence. b. Space: Modern science does not even know what 'space' actually is nor how it could actually warp and expand. c. Time: Modern science does not even know what 'time' actually is nor how it could actually warp and vary. d. Gravity: Modern science does not even know what 'gravity' actually is nor how gravity actually does what it appears to do. And for those who claim that 'gravity' is matter warping the fabric of spacetime, see 'b' and 'c' above. e. Speed of Light: 'Speed', distance divided by time, distance being two points in space with space between those two points. But yet, here again, modern science does not even know what space and time actually are that makes up 'speed' and they also claim that space can warp and expand and time can warp and vary, so how could they truly know even what the speed of light actually is that they utilize in many of the formulas? Speed of light should also warp, expand and vary depending upon what space and time it was in. And if the speed of light can warp, expand and vary in space and time, how then do far away astronomical observations actually work that are based upon light and the speed of light that could warp, expand and vary in actual reality? f. Photons: A photon swirls with the 'e' and 'm' energy fields 90 degrees to each other. A photon is also considered massless. What keeps the 'e' and 'm' energy fields together across the vast universe for billions of light years? And why doesn't the momentum of the 'e' and 'm' energy fields as they swirl about not fling them away from the central area of the photon? And why aren't photons that go across the vast universe torn apart by other photons, including photons with the exact same energy frequency, and/or by matter, matter being made up of quarks, electrons and interacting energy, quarks and electrons being considered charged particles, each with their respective magnetic field with them? Electricity is electricity and magnetism is magnetism varying possibly only in energy modality, energy density and energy frequency. So why doesn't the 'e' and 'm' of other photons and of matter basically tear apart a photon going across the vast universe? Also, 'if' a photon actually red shifts, where does the red shifted energy go and why does the photon red shift? And for those who claim space expanding causes a photon to red shift, see 'b' above. Why does radio 'em' (large 'em' waves) have low energy and gamma 'em' (small 'em' waves) have high energy? And for those who say E = hf; see also 'b' and 'c' above. (f = frequency, cycles per second. But modern science claims space can warp and expand and time can warp and vary. If 'space' warps and expands and/or 'time' warps and varies, what does that do to 'E'? And why doesn't 'E' keep space from expanding and time from varying?). g. Energy: Modern science claims that energy cannot be created nor destroyed, it's one of the foundations of physics. Hence, energy is either truly a finite amount and eternally existent, or modern science is wrong. First Law Of Thermodynamics: "Energy can neither be created nor destroyed." How exactly is 'energy' eternally existent? h. Existence and Non-Existence side by side throughout all of eternity. How? * NOTE: Even General Relativity and the Standard Model of Particle Physics cannot answer these items in a logical, coherent, inter-related way. Shouldn't these above items also require accurate answers?

#claudiaderham, obviously you're great. However, WHO told you that gravity should be quantized? You're barking up the wrong tree and will die of old age NOT finding a single graviton.
