“We use concepts like time and space, but we don’t really understand what this means microscopically. That might change… I think there’s something we haven’t found yet, and this will help us discover the origins of our universe.”
Erik Verlinde, in University of Amsterdam "in the Spotlight".
I got pretty hyped for emergent gravity a couple of years ago after seeing one of Erik's talks, and there's quite a few people working on similar stuff which is rather exciting, Sean Carroll seems to be heading in this direction
Can you show me where sean Carroll seems to be moving in this direction?
@@Carlos-fl6ch see e.g. web.stanford.edu/~oas/SI/QM/papers/SpaceFromQMCarroll.pdf
Also the final chapter of Sean Carroll’s book, Something Deeply Hidden
Can the direction of RG flow be opposite in de Sitter spacetime, contrary to AdS space case? 16:26
Big fan!!! I cant explain why but I gotta see if the data error cleaned up still has the tubal flow that it seemed to suggest.
So perhaps you could derive 'dark matter' effects (on rotating galaxies for example) through fluid mechanics? (i.e. Euler's / Navier Stokes equations) or through them to derive something about the information density of the vacuum?
It seems that Eric Verlinde is on the right track to explain the universe as an expanding entity without the need for a big bang, if he can show that it's missing entropy (as calculated from quantum mechanics) can be shown to be due to emergent gravity, and that the energy associated with it can eliminate the need for dark dark energy and that the accelerations associated with emerging gravity can eliminate the need for dark matter. If he does he can expect a Nobel prize in the future. It sounds like he's ahead of Sir Roger Penrose (anti-de sitter space) and Neil Turok in that they are still looking for something that will eliminate the need for the big bang. I wish him well and will be following the progress he and other physicists working in the same direction are making.
is he basically saying that acceleration is increasing mass, and that "mass" creates "gravity" and that "gravity" is dark energy?
Verlinde calculates everything in spheres of symmetry, and there are no predictions for the non-spherical cases that occur primarily in space. The observed pink filaments and walls of dark matter are completely beyond the reach of Verlinde's gravity at this time. The second problem is the holographic principle itself, for which it is not at all clear whether it applies, and if so, where is the "magical" projection surface. It would be most logical to identify it with string world planes, but there is no evidence yet in favor of string theory
“For every fact there is an infinity of hypotheses. ” ― Robert M. Pirsig (1928-2016)
This theory I find one of most promising ones. Human observation capabilities are very very limited. It is like observing a shadow without being able to see its cause. Therefor basically it remains just a state of information.
My proposed, amended Invisible/Holographic Principle of the Multiverse is a dual track pair of inverse principles. A duality within a duality. The Holographic Principle works in and only applies to indivudual universes. The complete Invisible/Holographic Principle works on and past the cosmic curtain of observation, out into the multiverse.
is he basically saying that acceleration is increasing mass, and that "mass" creates "gravity" and that "gravity" is dark energy?
As a non-scientist, I can't follow this. Which is not to diss it in any way. I think he's really onto something, and if you're an undergrad or grad physics student, it's probably amazing. I'd like to be able to grasp it somehow. Unfortunately, I'll have to wait until somebody besides Verlinde explains it in a youtube meant for laypeople.
i think there was another video where he make a demonstration with polymer rubber showing that it behaves differently if hit hard on the ground or put slowly. i think he was trying to show that same stuff will produce dark energy and gravity at the same time.
"If we waited long enough for dark energy to dominate the universe we would live in a a de Sitter space. But for right now we have other components as well" Hey don't sound so disappointed
10:40 14:10 paper
kzhead.info/sun/pc5vXcapbGeZlok/bejne.html - if there is no change in S then why is a delta in the equation at 8:52 ?
I think that he is referring to the fact that the total energy of the polymer changes, while the entropy stays consistent.
I'm thinking that another thing physicists have largely forgotten is the importance of Shannon(information) Entropy in these formalisms and unfortunately concentrate more on Thermodynamic(heat) Entropy.
Erik, the Quantum Information you're referring to is generated by the GRAVITATIONAL QUANTUM COMPUTATION. But Quantum Information alone cannot cause Gravity to emerge from it. It needs to be three Quantum Mechanical X-Factors to cause Gravity to emerge from it. The Trinity "X-Factors" are: 1. Quantum Gravitation (that causes acceleration/force); 2. Quantum Gravitational Entanglement (that transmit instant information faster than the speed of light); and 3. Gravitational Quantum Computation (that generates quantum information codes using Rhu Bit as opposed to Q Bit). There are two types of Quantum Computer. The one that use Q Bit and the other one is the quantum computer that uses Rhu Bit or R Bit that I have invented in Singapore as a result of my 30-year-long Basic Research on Quantum Gravity. Introducing the Ultimate Quantum Computing - The biggest and the most powerful Computer System in the entire Universe- The Universe itself. Quantum Entanglement is not only at microscopic or subatomic scale but it is also true at macroscopic scale up to a cosmic scale. This is proven by the empirical Theory of Quantum Gravitation, Quantum Gravitational Entanglement and Gravitational Quantum Computation for the entire Universe. These are the TRINITY (3-in-1) Equations and Codes For QUANTUM GRAVITATION, QUANTUM GRAVITATIONAL ENTANGLEMENT and GRAVITATIONAL QUANTUM COMPUTATION - The HOLY GRAILS of Physics: 1. Quantum Anti-Gravity = Spin Up Quantum Entanglement = 0 Rhu Bit or R Bit: QAG = ∆QGOρ < ∆QGFρ = ↑α 2. Quantum Gravity = Spin Down Quantum Entanglement = 1 Rhu Bit or R Bit: QG = ∆QGOρ > ∆QGFρ = ↓α 3. Quantum Neutral Gravity = Superposition Quantum Entanglement = 01 or 10 Rhu Bit or R Bit: QNG = ∆QGOρ = ∆QGFρ = ↑↓α We now have a working Quantum Theory of Gravity that is testable and complete with reproducible empirical experiments with the same results if repeated over and over again and again, confirmed by empirical observations in nature with 7-Sigma level results, guided by empirical laws and physical/mathematical Trinity God Equations that are predictive, precise and does no collapse even in high energies of Big Bang and singularity of Black Hole. FYI: Quantum Gravity or Quantum Gravitation have three types that are equivalent to and manifested by Quantum Computational Gravitation- the biggest and most powerful Computer Software Program and Hardware in the Universe and Quantum Gravitational Entanglement - a Quantum Entanglement in Macroscopic Cosmic Scale namely: 1. Quantum Anti-Gravity = Spin Up Quantum Entanglement State; 2. Quantum Neutral Gravity = Superposition Quantum Entanglement State; and 3. Quantum Gravity = Spin Down Quantum Entanglement State. More detailed information could be found on the published papers 2 years ago in London, Paris, and Zurich, online and at the two scientific Journals ACADEMIA and REAL TRUE NATURE. Alternatively, you can google the name of the author ROEL REAL ROVIRA to arrive at the published paper on Quantum Gravity. Most recently, additional two well respected scientific journals namely NATURE and the AMERICAN PHYSICAL SOCIETY APS Physical Review Journals have officially invited this author to submit manuscripts on his Research on Quantum Gravity for publication for PRX QUANTUM in preparation for a celebration for International Year of Quantum IYQ 2025 to showcase the best papers of the year. Quantum Gravitation is governed by and follow the Trinity Laws, Mathematics and Physics of Quantum Gravitation, Gravitational Quantum Computation and Quantum Gravitational Entanglement. We now have a new Laws of Physics which are the heart of the Quantum Theory of Gravity published in London. Paris and Zurich last December 2022 as follows: 1. First Law of Quantum Gravitation: Rovira’s Universal Law of Quantum Gravitation: “The greater mass density of gravitating Quantum Objects than the Quantum Gravitational Field causes a downward acceleration of the Quantum Objects in a Quantum Gravitational Field instantaneously mediated by Graviton.” - Roel Real Rovira Equation for Quantum Gravity, and Spin Down Quantum Gravitational Entanglement: QG = ∆QGOρ > ∆QGFρ = ↓α Where: QG is Quantum Gravity in Rovira (value of downward acceleration force due to quantum gravity) in kg. ∆QGOρ is Differential Change in greater mass density of Quantum Gravitating Objects than the mass density of Quantum Gravitational Field in kg/m2 or g/cm3. ∆QGFρ is Differential Change in mass density of Quantum Gravitational Field in kg/m2 or g/cm3. ↓α is the Resultant Downward Acceleration of Gravitating Quantum Objects in mtr/sec. 2. Second Law of Quantum Gravitation: Rovira’s Universal Law of Quantum Anti-Gravity. “The lesser mass density of gravitating Quantum Objects than the Quantum Gravitational Field causes an upward acceleration of the Quantum Objects in a Quantum Gravitational Field instantaneously mediated by Graviton.” -Roel Real Rovira Equation for Quantum Anti-Gravity/Spin Up Quantum Gravitational Entanglement: QAG = ∆QGOρ < ∆QGFρ = ↑α Where: QAG is Quantum Anti-Gravity in Rovira (value of upward acceleration force due to quantum anti-gravity) in kg. ∆QGOρ is Differential Change in lesser mass density of Quantum Anti-Gravitating Objects than the mass density of Quantum Gravitational Field in kg/m2 or g/cm3. ∆QGFρ is Differential Change in mass density of Quantum Gravitational Field in kg/m2 or g/cm3. ↑α is the Resultant Upward Acceleration of Anti-Gravitating Quantum Objects in mtr/sec. 3. Third Law of Quantum Gravitation: Rovira’s Law of Quantum Neutral Gravitation. “The equal mass density of gravitating Quantum Objects and the Quantum Gravitational Field causes a zero acceleration or floating or hoovering of the gravitating Quantum Objects in a Quantum Gravitational Field, instantaneously mediated by Graviton.” - Roel real Rovira Equation for Quantum Neutral Gravity and Superposition Quantum Gravitational Entanglement: QNG = ∆QGOρ = ∆QGFρ = ↑↓α Where: QNG is Quantum Neutral Gravity in Rovira (value of zero acceleration force due to quantum neutral gravity) in kg. ∆QGOρ is Differential Change in equal mass density of Quantum Neutral Gravitating Objects to the mass density of Quantum Gravitational Field in kg/m2 or g/cm3. ∆QGFρ is Differential Change in mass density of Quantum Gravitational Field in kg/m2 or g/cm3. ↑↓0α is the Resultant zero acceleration or non-acceleration of Neutral Gravitating Quantum Objects in mtr/sec. For more detailed information on these 3-in-1 Trinity Laws and Equations for Quantum Gravitation, Gravitational Quantum Computation, and Quantum Gravitational Entanglement - The Real True Nature of Quantum Gravitation, look it up at the two scientific journals ACADEMIA and REAL TRUE NATURE or google the name of the author ROEL REAL ROVIRA.
the crystal have memory effects is similar to the water crystal claims having memory effects that Brian Josephson considers legitimate. Water is negentropic as a macroquantum molecule.
@9:00 entropy does not cause these forces. Electromagnetism is causing the polymer to contract and thermal energy permits it to transition through a few energy barriers. Same with his "entropic gravity". He seems to have taken a few too many LSDs and really swallowed holism and emergence memes. It is not that these notions have no place in scientific explanations, but you have to be careful about what is fundamental and what truly is a more collective phenomenon that cannot be reduced to Hamiltonian time evolution. There are few such systems in nature, that are genuinely _strongly_ emergent, and perhaps only one known to us. (!)
Look more into photons and scattering
Nonsense!! Give a single testable prediction using current technology. He can't!
"They them" ... and here i thought this was about science.
Its a shame this american culture blew over to the netherlands
People who go by they/them can do science too
Gravity doesn't suck, it blows.
