I don't understand any of this, and I've been watching for more than a year. At this point, I'm just waiting for the catchphrase at the end.
Don’t worry. You will. You just have to spend some time quietly pondering it and trying to visualize what it means. Slowly but surely every new quantum topic you learn, you begin to understand it. You really do have to just ponder it. Sometimes it takes trying to describe it out loud. You’ll get it. If you’re even interested in it at all, you’ll get these things. And remember, you’re not supposed to understand anything all at once. Knowledge gradually unfolds based on our interest level and reflection. You got this.
One of my college textbooks, decades ago, was written by Misner, Thorne, and Wheeler - back when I presume Kip Thorne was a newly minted PHD. I enjoyed and learned a lot from the book which is still in my library somewhere...
I don't even remember when I started watching jmg. Somewhere around 2016? Later? Around the same time i started watching Isaac Arthur i guess. And here he is, with hundreds of thousands of subscribers. And he's never ever failed to deliver the BEST videos with the BEST narration. Starting to wonder whether he's actually human. Are you a supermind, m. Godier?
I remember a fun remote viewer sci-fi story by Arthur C. Clarke, that used the concepts of quantum foam and the casimir effect to create micro wormholes in space and time. It was called The Light of Other Days, from about 25 years ago.
My Mom was at Princeton in the 70s when Wheeler was still there. She had dinner with him a couple times, she'd always tell me that it was super cool being able to talk to him about Einstein. I'm always jealous that she got to know Wheeler and some other famous physicists. It's always fun when one of the space/physics channels I watch talk about him so I can show her the video and reinforce how cool Wheeler was.
Wheeler was Feynman's PhD thesis. When they met for the first time, Wheeler took off his watch and put in on his desk to emphasize to Feynman that his time was limited. The next time they met, Feynman took his own watch off and placed it next to Wheeler's watch. The third time they met and at all subsequent meetings, neither man took their watch off.

I’ve been telling my curious friends that drones abusing vacuums, aerogels, and the Casimir effect are probably more in line with “UAP” reports than it ever being ET. I’m open to it, but the way they present sounds like 50-50 radar spoofing and drones. I’m glad to see a popular UA-camrs covering the Casimir effect. More videos like this!
I believe that this hypothetical pre-universe quantum foam that we are peering back to in this video, is actually indistinguishable from the state of heat death that this universe shall become. This implies a cycle of universes, exploding out, dispersing energy, settling down into heat-death quantum foam, until another big bang event inevitably occurs due to quantum fluctuations with infinite time.
The Casimir effect was originally proposed by Hendrik Casimir in 1948. This effect has also been used to explain aggregative behaviours in particulate emulsions, especially paints. Interesting, relatively small black holes (Kugelblitz black holes) have been proposed as an energy source. The problem with Hawking radiation is that it's not being radiated by the singularity. Particles that fall inside the event horizon can easily recombine with their opposite antiparticle, and this applies too for those created outside the event horizon; black holes do not necessarily act as a virtual particle radiation source. Space inside the event horizon is the same as space outside, and although the gravitational field is significant, all particles are exposed to the same free-fall acceleration, so they can behave just as particles beyond the horizon behave.
Everything below the horizon is unobservable and thus conjecture. A favorite conjecture of mine is that all local bh are local instances of a single singularity connected backwards in many time dimensions.
I think the Kasimir effect is way more important on a theoretical and mathematical level than something we can somehow harness. Still, it's absolutely incredible what's happening in what we think of as empty space or vacuum.

Chances are it would violate the uncertainty principle that prevents us from knowing ‘everything’ about ‘something’. You could argue the Big Bang / quantum fluctuation (discussed perfectly in this video) arises from the same principle. In QM specifically, the lowest level of the harmonic oscillator is found to be non zero - in others words if you build a perfect pendulum then it cannot ever be in a ground state of zero - it is always swinging. This in turn implies the presence of a perfect undamped restoring force keeping the harmonic oscillation in motion. Ditto in a vacuum, we know that a light wave propagates with constant speed, evidently undamped, and hence zero dispersion with all frequencies travelling at the same speed. Something has to give - I’m hoping it’s zero dispersion in the vacuum.
A simple non scientific answer: a thing can only exist in relation to something else. A no-thing must also exist in relation to a thing. Therefore a no-thing must also be a thing.
Interesting coincidence regarding the varying speed of photons from the blazar....Matt over at PBS Spacetime just this week talked about a modification to Special Relativity in which at very high energies, the speed of light may depend on wavelength. Having both the former and latter concept pop up in my science diet this week is intriguing.
This is profound. it is commonplace to conflate the limitation on speed (of anything) that arises out of special relativity, with the constancy of light speed as a function of frequency (zero dispersion in a vacuum.). They may not necessarily be related. In nature, other than in a vacuum we readily observe dispersion. However for light in a vacuum we do not, and the jury for the existence of the he aether is still out (and if it existed it would likely be dispersive.).
Not quite. All photons travel at the speed of light. It's possible that the speed of light is different for different energies of light. Just like the speed of sound changes depending on the density of the medium, for example.
I’ll chime in here - cold fusion could really be the release of stored energy from certain exotic materials. And let’s face it, nature certainly knows how to store energy in matter. So for me cold fusion was an experiment to extract stored energy - the discoverers upset a lot of people with their choice of name and the result was the physics equivalent of the Spanish Inquisition. It still goes on today but fortunately JWT is revealing lots of nice inconsistencies in the standard model.
@@stevemartz5610 - I’ll dog a little more as I have a reference on this subject that was very even handed. I’m fairly sure the data was correct but the mechanism was named incorrectly. The academic physics‘ ‘pile on’ was shameful but at least via JWT the Overton window on meaningful discussions is moving in the right direction, at last.
Casimir effect is the result of the inability of photons to slip ion between the plates. A photon cannot be trapped inside of a volume that can not accomodate at least half its wavelength. Thus, more photons outside the plates than can slip in between the plates.
Stephen Baxter and Arthur C Clarke wrote an amazing novel using some of these theorems, The Light of Other Days. Basically, they use squeezed vacuum technology to build wormhole cameras, and it goes through amazing implications for what that means for society. And THEN they figure out that it can be used to view the past, and then it gets wild from there!
While we can't really claim that Wheeler was "underrated" he did have an unusual quality even among scientists. He allowed Nature to be Nature, without interjecting his own preconceived suppositions, and encouraged himself and others to simply appreciate and accept what Nature has to offer. This allowed him to pre-emptively accept notions like quantum field theory, even that "there is only one electron" for the sake of practical application in time-space; and he mentored others like Feynman and Everett to make ground-breaking realizations about the consequences of how reality actually works, whether that makes sense to your limited monkey-brain or not. This kind of outside-the-box humility and perception may go beyond what current experiments can demonstrate, but it also allows one to simply accept the facts of what experiments do demonstrate without apology. He got weirder things than you as toy prizes in his breakfast cereal, and he let them be what they are. This is how truly breakthrough changes in perception of reality are born...
If you had two metal plates in a vacuum close enough together such that the Casimir force was significant. Then apply a strong magnetic field such that say positrons would be deflected to one plate and electrons would be deflected to the other plate, so if a positron/electron pair materialised they may be split up, recovered and energy extracted from the vacuum. this idea could well be rubbish but if it does work, you heard it here first and no corporation can patent it. The idea is similar to Hawking radiation except a magnet substitutes for a black hole, no singularity required.
Thanks John, 5:49 Can't emit; so how do they cease? You liken it to matter anit-matter pair, so how about +/- matter pairs, gravitons or their contituants, new quarks perhaps or the largest quarka? Could we harvest negative mass for warp drives from the QFoam?
I am not sure how this author got his concepts so mixed up. He speaks of the quantum vacuum as if is the same topic that J.A. Wheeler was referring to in his early speculations ( which he called "geometrodynamics" at times) about spacetime itself at the smallest distances. The vacuum that comes up in quantum electrodynamics (and gives rise to much of the "push" measured in the Casimer effect), is something has been described in various terms since the forties, and steadily clarified since then by Tomonaga, Schwinger, and others to a fixed feature of QED. This was further extended in a natural way to any other fields in the standard models beside the electron/positron and photon field, so that we know in fairly quantitative terms the contribution of virtual/vacuum terms to any calculation of a subatomic process. What Wheeler was on about was Planck scale physics and what that ultimate scale bodes for spacetime itself, quite apart from the fields mentioned above.His instinct was that as future physics approached a description at that scale, quantum mechanics would "win" in priority over classical gravitational solutions, at least, in forcing the Heisenberg principle on gravity through violent, even divergent oscillations in the fabric of spacetime, indeed even bringing in topological effects such as mini-wormholes. He was a great man, well ahead of his time and boundlessly brave in pushing boundaries. regards, DKB
This is one of the most interesting questions in cosmology. Since gravity was the first to emerge during symmetry breaking it was certainly in a pure quantum state and since we don't yet understand quantum gravity we are certainly missing some big pieces of the big bang picture. Although most of the big bang theory hangs together, the recent observations by JWST show that massive galaxies formed long before current theories can account for. The question I want to see answered is whether primordial black holes could have formed before inflation started. If so we likely have a lot of the early universe theories backwards because the effects of inflation on billions of primordial black holes created under the influence of quantum gravity is something we need to contemplate.
After everything else is done happening, Hawking radiation will very gradually fill the universe with uniform matter/energy, which (my guess) eventually reaches a flash point or big bang. No need for virtual particles to do anything unusual or for an expanding universe. Einstein finally gets his static universe, lol.
There would never be a Point at which Everything is Done. There's No Endings only New Beginnings. Every Dp-brane/Q-Particle & Blackhole(Db-branes) is, has been & Will Become Everything, a Universe, a Multiverse & Beyond Forever & Ever. Eternity had a Beginning. All Creations have Beginnings & Ends but the All-Creator/All-Being is Self-Existent, or has No Beginning or End. That is Pure Infinite Light-Energy-Force, the Source of All Things/Being & Creation. Many Blessings to you anyway!.
Most of the time, 95% of the time, Godier and beer go together wonderfully. But when it comes to quantum physics I sometimes have to wait until tomorrow.
I'm very nearsighted. Without my glasses, everything I look at is as smooth and clear as everything else, unless I'm very very close to the object. So only on the smallest of scales can I clearly see what is going on, and further away, I see everything as universally and equally distinct. This has been my life for over 40 years. This being the case, why is it such a hard concept for scientists to grasp? The notion that the universe changes when you pass a certain scale isn't hard to grasp, so long as you have been required to see the world through different eyes.
For me, it is difficult to construct a model for a quantum vacuum without a contextual frame for it to exist pre-universe. Thanks for leading me to wonder.
The galaxies ride upon the surface of a hypersphere, the interior of which is filled with entropy. Black holes display their great mass by tucking it into the interior entropy volume. Abundance quantities themselves are laden with bottlenecks that impose issues of locality. It may be impossible for a bang-type event to close in the same moment it appears if it should involve more than 97 bits.
Something that personally astounds me regarding science are the instances when a theory is presented, and then later proven to be true. Compared to observing phenomena and then figuring out how its process works, I think the former really attests to the capability of the human mind.
It’s also a path to hell for STEM students who have a hard time applying their ideas to reality… I know what you mean, but a lot of stuff is provable and works. But proving theories vs explaining phenomenon is a tenet of that bad thinking in my experience. Obviously for just learning science it’s ok and obviously necessary l. But godawful for something by like geoengineering. I’m rambling, but I think both ways of learning are important. One or the other isn’t enough. It needs to be both.
Photons traveling through different mediums will travel at different speeds depending upon the medium i.e. water, glass, vacuum. In the case of the blazer the photons arriving at different speeds can be explained this way.
I still hate Virtual Particles, they're a bad abstraction. Since everything Quantum is a Wave, it's much better to talk about waves. Waves handily explain the Casimer effect, the nearly atomically smooth metal being so close together means certain wave-lengths can't exist between the plates; which causes the pressure. Waves explain matter anti-matter interactions, as apposing wave phases cancel out; the energy generally pops out as a Photon which is it's own anti-particle. The event horizon of a black-hole means the Quantum "Foam" ripples can't cancel out so the waves that travel away from the black-hole carry away the energy equal to the anti-waves energy going into the black-hole.
Waves is a good analogy, and pinpoints why application of the Casimir effect to technologies is somewhat difficult to harness and develop. Our current quantum technology at larger scale than some atoms would destroy the object we want to manipulate. If we could use some standing wave electrostatic time dilation or something (Clark tech I know) safe where temperature stays normal, and there isn’t blueshift maybe we can actually harness this quirky effect and apply it to something interesting.
Hal Puthoff theorises there is enough energy within quantum foam in a volume the size of a coffee cup to boil all the oceans of the earth , some say this energy might be underestimated by many orders of magnitude
Is it possible that light travels at different speeds in interstellar space? And then slows down when it reaches solar systems due to the star gravity or some other influence?
Are you applying it to the Big Bang? That’s what Jon is talking about here fasho We just a bubble in a vacuum that’s expanding and can pop but we’d never know it. The stability of it all is a great question.
I have always thought that a negative quantum energy fluctuation is the start of our universe. The Higgs still seeking its energy state should be an indication of this.
Nice episode. Quantum foam and gravitational waves in a energy density regime. What if the vacuum is closer to true outside the universe. ( CMB relic not seen with the rest. ). Hawking radiation and the end of a black hole. A natural limit/cutoff/minimum for white holes. Besides Quantum flux without pair production or deposit ring structure or such is ignoring a bit. The universe a natural cutoff regime or limit. A boltzmann time bomb. Time as we know it ending when the last particle decays. Further out and photons don't even come close to each other. The universe in a sudo ground state. The work done. Cumulative effects of particle production and decays and red shifting and space expending and where. Gravity a byproduct of mass and energy in a given area. Quantum flux included, and might be seen as part of the energy in a given frame. If part of a pair or ring of universes produced by natural cutoffs. Then you can start to construct theoretical and probabilistic modeling for where they might exist out there. Multiple viable paths to pre bang conditions. I love the topic matter, but it also makes me want to argue points. S.A.I. and could the universe have a cryptographic imprint. The universe at flash over point 12.5 light year diamiter with error bars. Cherenkov radiation and FTL in a medium and production surfing a Gravity wave. Flow and fluidity and fluidic states. Phase transition from coldest to honest state. But back to the topic. Probability and predictability and particle production from quantum foam and gravitational waves and energy density regimes. Energy thresholds to produce particles. The no FTL seen in a vacuum and no Quantum foam/flux spikes seen above another very small point should make people question things. The larger scale artifacting and big galaxies forming so early in the universe. The hubble tension and S8. Keep up the good work. I love the topics you go over.
Shouldn't the "absorption" of a virtual particle on the inside of the event horizon that is equivalent to the Hawking Ratiation event outside the horizon make the blackhole and the mass/size/energy of the universe bigger at the same time?
I haven't heard of anybody generating any energy from particle antiparticle pairs. I'd like to hear how. I assume this would be a net energy loss as with hawking radiation
Quantum fluctuations in space could be caused the 'connection' of entangled particles. Spacetime itself seems to be an emergent property. Do the wormholes of entanglement create and excite the quantum fields? Holographically, particles never separate
Doesn't the quantum fluctuation big bang idea require that there already be a universe within whose vacuum a fluctuation occurs? If there's a vacuum that fluctuates, that is by definition already a universe, right?
In All cases besides the Primordial High-Energy State Spacetime Retains it's Granularity & Foaminess or Quantized Form. That would be the Dp-brane or D-Instanton i.e. the Fundamental Singlet D-Graviton or D-Fracton. Supersolids are Time Reversal Invariant. Outer-Spacetime is the Ultimate Medium of All Things/Being, Existence, the Canvas of Creation, & Waters of Potentiality or 'Quantum Wave Function'(Scalar GR).

This allowed him to pre-emptively accept notions like quantum field theory, even that "there is only one electron" for the sake of practical application in time-space; and he mentored others like Feynman and Everett to make ground-breaking realizations about the consequences of how reality actually works, whether that makes sense to your limited monkey-brain or not.
This kind of outside-the-box humility and perception may go beyond what current experiments can demonstrate, but it also allows one to simply accept the facts of what experiments do demonstrate without apology. He got weirder things than you as toy prizes in his breakfast cereal, and he let them be what they are. This is how truly breakthrough changes in perception of reality are born...
A really great, succinct, summary video of where we are.
I get quantum foam from Tacobell
The latest breakthrough discovery about black holes.
my garloids quantum foam when i taco their bell if you catch my drift
It's bad when your sharts,rip a hole in space time😅
Using this new information, we now know that we did not detect two blackholes colliding. It was one brown hole exploding far closer.
Mind bending stuff!😲🌌☄🚀🧙
If you had two metal plates in a vacuum close enough together such that the Casimir force was significant. Then apply a strong magnetic field such that say positrons would be deflected to one plate and electrons would be deflected to the other plate, so if a positron/electron pair materialised they may be split up, recovered and energy extracted from the vacuum. this idea could well be rubbish but if it does work, you heard it here first and no corporation can patent it. The idea is similar to Hawking radiation except a magnet substitutes for a black hole, no singularity required.
What an incredible video!
This was so interesting.
Thank you!
Sound has gotten better, John. Not as ridiculously bassy as before. Vibrato still needs to be softened.
"Quantum foam makes me roam".
“Quantum foam is my loam”
That's what I immediately thought of lol.
Quandam phone?
Gotta watch out for transcription errors.
Something something West Virginia
Thanks John,
5:49 Can't emit; so how do they cease?
You liken it to matter anit-matter pair, so how about +/- matter pairs, gravitons or their contituants, new quarks perhaps or the largest quarka?
Could we harvest negative mass for warp drives from the QFoam?
What is the background music you use in your videos JMG?
perfect timing
"...in which we liiiiiiiiiiiiiive" laughting from this every time) thnx for your videos, really authentic and interesting. good luck with channel!
I am not sure how this author got his concepts so mixed up. He speaks of the quantum vacuum as if is the same topic that J.A. Wheeler was referring to in his early speculations ( which he called "geometrodynamics" at times) about spacetime itself at the smallest distances. The vacuum that comes up in quantum electrodynamics (and gives rise to much of the "push" measured in the Casimer effect), is something has been described in various terms since the forties, and steadily clarified since then by Tomonaga, Schwinger, and others to a fixed feature of QED. This was further extended in a natural way to any other fields in the standard models beside the electron/positron and photon field, so that we know in fairly quantitative terms the contribution of virtual/vacuum terms to any calculation of a subatomic process.
What Wheeler was on about was Planck scale physics and what that ultimate scale bodes for spacetime itself, quite apart from the fields mentioned above.His instinct was that as future physics approached a description at that scale, quantum mechanics would "win" in priority over classical gravitational solutions, at least, in forcing the Heisenberg principle on gravity through violent, even divergent oscillations in the fabric of spacetime, indeed even bringing in topological effects such as mini-wormholes.
He was a great man, well ahead of his time and boundlessly brave in pushing boundaries.

Untold sextillions of virtual particles popped and out of existence inside my thumb while i typed this. I think I could feel them.
Is there an audio version of your book?
This is one of the most interesting questions in cosmology. Since gravity was the first to emerge during symmetry breaking it was certainly in a pure quantum state and since we don't yet understand quantum gravity we are certainly missing some big pieces of the big bang picture. Although most of the big bang theory hangs together, the recent observations by JWST show that massive galaxies formed long before current theories can account for. The question I want to see answered is whether primordial black holes could have formed before inflation started. If so we likely have a lot of the early universe theories backwards because the effects of inflation on billions of primordial black holes created under the influence of quantum gravity is something we need to contemplate.
Thank you sir 🙏
After everything else is done happening, Hawking radiation will very gradually fill the universe with uniform matter/energy, which (my guess) eventually reaches a flash point or big bang. No need for virtual particles to do anything unusual or for an expanding universe. Einstein finally gets his static universe, lol.
There would never be a Point at which Everything is Done. There's No Endings only New Beginnings. Every Dp-brane/Q-Particle & Blackhole(Db-branes) is, has been & Will Become Everything, a Universe, a Multiverse & Beyond Forever & Ever. Eternity had a Beginning. All Creations have Beginnings & Ends but the All-Creator/All-Being is Self-Existent, or has No Beginning or End. That is Pure Infinite Light-Energy-Force, the Source of All Things/Being & Creation. Many Blessings to you anyway!.
Bravo once again.
Most of the time, 95% of the time, Godier and beer go together wonderfully. But when it comes to quantum physics I sometimes have to wait until tomorrow.
I think the computer hosting John glitched out a bit at the end, there. 😅
Virtual black holes spewing out Hawking radiation could be part of the explanation why there was just the slightest amount of matter over antimatter.
I'm very nearsighted. Without my glasses, everything I look at is as smooth and clear as everything else, unless I'm very very close to the object. So only on the smallest of scales can I clearly see what is going on, and further away, I see everything as universally and equally distinct. This has been my life for over 40 years.
This being the case, why is it such a hard concept for scientists to grasp? The notion that the universe changes when you pass a certain scale isn't hard to grasp, so long as you have been required to see the world through different eyes.
For me, it is difficult to construct a model for a quantum vacuum without a contextual frame for it to exist pre-universe. Thanks for leading me to wonder.
Contemplating the universe is one of my favorite escapes from real life. That, and the alt reality I visit every night.
The galaxies ride upon the surface of a hypersphere, the interior of which is filled with entropy. Black holes display their great mass by tucking it into the interior entropy volume. Abundance quantities themselves are laden with bottlenecks that impose issues of locality. It may be impossible for a bang-type event to close in the same moment it appears if it should involve more than 97 bits.
Put up 3mins ago. Perfect timing ✌️🫠✌️
Something that personally astounds me regarding science are the instances when a theory is presented, and then later proven to be true. Compared to observing phenomena and then figuring out how its process works, I think the former really attests to the capability of the human mind.
It’s also a path to hell for STEM students who have a hard time applying their ideas to reality…
I know what you mean, but a lot of stuff is provable and works.
But proving theories vs explaining phenomenon is a tenet of that bad thinking in my experience.
Obviously for just learning science it’s ok and obviously necessary l.
But godawful for something by like geoengineering.
I’m rambling, but I think both ways of learning are important. One or the other isn’t enough.
It needs to be both.
Photons traveling through different mediums will travel at different speeds depending upon the medium i.e. water, glass, vacuum. In the case of the blazer the photons arriving at different speeds can be explained this way.
Quantum foam makes me roam.
John, i would love your take on the possibility that the big bang arose from a quantum fluctuation.
I still hate Virtual Particles, they're a bad abstraction. Since everything Quantum is a Wave, it's much better to talk about waves. Waves handily explain the Casimer effect, the nearly atomically smooth metal being so close together means certain wave-lengths can't exist between the plates; which causes the pressure. Waves explain matter anti-matter interactions, as apposing wave phases cancel out; the energy generally pops out as a Photon which is it's own anti-particle. The event horizon of a black-hole means the Quantum "Foam" ripples can't cancel out so the waves that travel away from the black-hole carry away the energy equal to the anti-waves energy going into the black-hole.
Waves is a good analogy, and pinpoints why application of the Casimir effect to technologies is somewhat difficult to harness and develop.
Our current quantum technology at larger scale than some atoms would destroy the object we want to manipulate.
If we could use some standing wave electrostatic time dilation or something (Clark tech I know) safe where temperature stays normal, and there isn’t blueshift maybe we can actually harness this quirky effect and apply it to something interesting.
Hal Puthoff theorises there is enough energy within quantum foam in a volume the size of a coffee cup to boil all the oceans of the earth , some say this energy might be underestimated by many orders of magnitude
I ordered new shoes on line. The shoes showed up BEFORE I ordered them! Turns out that they were packed in Quantum Bubble Wrap.
Is it possible that light travels at different speeds in interstellar space? And then slows down when it reaches solar systems due to the star gravity or some other influence?
Good morning everyone
My Theory of Super-Tension is mostly a Combination of M-theory('Braneworld' Physics) and 'Fracton Gravity'.
I still wonder if there's some way to harness the energy from the cassimir effect. Seems it would be virtually unlimited?
Im not convinced that gravity needs to be quantized. It would be great to see a video explaining the need for quantum gravity
Babe wake up! A new space vid just dropped
I've never heard Hawkings radiation explained so well
Just a thought - Could the Casimir effect be driving the expansion of the Universe?
Are you applying it to the Big Bang?
That’s what Jon is talking about here fasho
We just a bubble in a vacuum that’s expanding and can pop but we’d never know it.
The stability of it all is a great question.
ER =EPR or worm holes and entanglement could be the basis of the quantum foam. Susskind and Maldacena 2013.
Could this be the means by which universes reproduce? (in a hypothesis that posits such a thing)
I have always thought that a negative quantum energy fluctuation is the start of our universe. The Higgs still seeking its energy state should be an indication of this.
I swear I have developed a JMG sixth sense
Nice episode. Quantum foam and gravitational waves in a energy density regime. What if the vacuum is closer to true outside the universe. ( CMB relic not seen with the rest. ). Hawking radiation and the end of a black hole. A natural limit/cutoff/minimum for white holes. Besides Quantum flux without pair production or deposit ring structure or such is ignoring a bit. The universe a natural cutoff regime or limit. A boltzmann time bomb. Time as we know it ending when the last particle decays. Further out and photons don't even come close to each other. The universe in a sudo ground state. The work done. Cumulative effects of particle production and decays and red shifting and space expending and where. Gravity a byproduct of mass and energy in a given area. Quantum flux included, and might be seen as part of the energy in a given frame. If part of a pair or ring of universes produced by natural cutoffs. Then you can start to construct theoretical and probabilistic modeling for where they might exist out there. Multiple viable paths to pre bang conditions.
I love the topic matter, but it also makes me want to argue points. S.A.I. and could the universe have a cryptographic imprint. The universe at flash over point 12.5 light year diamiter with error bars. Cherenkov radiation and FTL in a medium and production surfing a Gravity wave. Flow and fluidity and fluidic states. Phase transition from coldest to honest state. But back to the topic. Probability and predictability and particle production from quantum foam and gravitational waves and energy density regimes. Energy thresholds to produce particles. The no FTL seen in a vacuum and no Quantum foam/flux spikes seen above another very small point should make people question things. The larger scale artifacting and big galaxies forming so early in the universe. The hubble tension and S8.
Keep up the good work. I love the topics you go over.
Shouldn't the "absorption" of a virtual particle on the inside of the event horizon that is equivalent to the Hawking Ratiation event outside the horizon make the blackhole and the mass/size/energy of the universe bigger at the same time?
I haven't heard of anybody generating any energy from particle antiparticle pairs. I'd like to hear how. I assume this would be a net energy loss as with hawking radiation
When particle anti-particle pairs collide they essentially get converted into energy.
Quantum fluctuations in space could be caused the 'connection' of entangled particles. Spacetime itself seems to be an emergent property. Do the wormholes of entanglement create and excite the quantum fields? Holographically, particles never separate
All Elementary Q-Particles are like Microscopic Blackholes & the Massive D-Graviton is a Plankian Black Hole that Decays via Super-Tension.
Doesn't the quantum fluctuation big bang idea require that there already be a universe within whose vacuum a fluctuation occurs? If there's a vacuum that fluctuates, that is by definition already a universe, right?
Why isn't the Casemire effect not just the gravity of the 2 plates pulling on each other?
Early Sunday Crew ❤
Casimir effect just needs bigger plates in space maybe two black holes? Oh oh oh.... Maybe it explains the final parsec problem
What if the photons while traveling from point A to B they pass within distance of a black hole? Wouldn't that slow them?
In All cases besides the Primordial High-Energy State Spacetime Retains it's Granularity & Foaminess or Quantized Form. That would be the Dp-brane or D-Instanton i.e. the Fundamental Singlet D-Graviton or D-Fracton. Supersolids are Time Reversal Invariant. Outer-Spacetime is the Ultimate Medium of All Things/Being, Existence, the Canvas of Creation, & Waters of Potentiality or 'Quantum Wave Function'(Scalar GR).
