Can we just take a moment to acknowledge that Roger Penrose well into his 90s is still able to demonstrate a level of mental acuity most of us will never achieve even in our prime.
I put it to you that he has tried very very very hard all his life to think... and this may well have something to do with his ability to think.. @@pikiwiki
@@keithtomey5046 I agree entirely. Your brain is a muscle just like any other. If you don't exercise it, no doubt it will deteriorate at a much faster rate.
Roger deals with what is right in front of us, defines the elements, identifies one of the knots, and then untangles it or -- at a minimum, puts a clearer focus on the frame of reference of the problem field at which point he begins again... Thank you Roger for letting us see what you see.
An industry produces a product. Now, this product is attempting to decode the secret of how that industry came into existence in the first place. What the product does not, and cannot, know is that it lacks the necessary faculties to decode that industry.
Yes, maybe. But then by the same logic, a product of the industry _may_ be able to decode how the industry came into existence... the uncertainty goes both ways.
@@classicalmechanic8914 I think this is right and it’s also insightful, although I would change the word “present” to the word “future”. I think we can describe the present as a transition of no duration between the future and the past. Our conscious feeling of the present is actually created from the past, ie what has already happened. if we consider that quantum mechanics is predictive only, not descriptive things start to make sense.
@@sandipan_993 There is past but the past is not relative. You can't change your past therefore past is absolute. All you can do is change distant observer's present which would appear to be in your past if you synchronized clocks with distant observer.

Why is there giant organisms (a few miles long) out in space that look like worms as something you would see under a microscope ,but in a radiation spectrum apparently and not one we can see with our eyes? So the most smallest known organisms are also the largest so that's why I feel the universe is more in tuned with opposites. Or it really could just be that space is some form of fluid we can't see and that we know organisms grow larger in a larger environment so obviously out in space the organisms are huge (the video I saw of NASA in 1960's said 10 miles long)
and they use the man-made, energy-only virtual dimension, which technically doesn't exist without the circuitry to decode it, to communicate. can you travel back in time in this dimension? yes, invariably. forwards? nope. but prediction closes that gap, to rework 'the future' as 'certainty'
Surely in a block universe all possible futures and pasts exist. The question then becomes, is there a special route through the universe that has more validity, more reason to be called 'reality', than others ? And if so, then can we change that route to another in order, effectively as far as we are concerned, change past & future ?
Why is Avshalom talking about QM? QM tells us that we are ignorant about most of the universe but it doesn't really point us in any helpful direction(s). QM could only be used to say something profound about the universe if it were a complete theory that explained all quantum effects.

Roger Penrose is a master at having intuitions that are correct, so I listen very carefully of what ideas he has. Greatest mind of our time since J. S. Bach.
2:51 To be fair the universe does not require more than 3 dimensions. We only need the pseudo extra dimension to make sense sense of it and describe it to ourselves :) 9:41 Kind of falls into the above. The concept of timing an synchronization appears to exist in all things, but I feel that it may be very different to what we may commonly think of as time. Just the same no additional dimension is required for it. 16:08 At best I could extend 3 dimensions to have 6 positive degrees of freedom :/ > Not a physicists, just my thoughts on it :) Thanks for posting the talk :)
If there is an inside and outside of spacetime then outside of spacetime there is no space separating things so you could take a shortcut that takes no time. Thus entanglement
There must be at least one extra spatial dimension. Why? If Physicists describe electrons as point particles with no volume, where is the mass of the particle? Can one extra spatial dimension produce a geometric explanation of the 1/2 spin of electrons? The following is an extension of the old Kaluza-Klein theory. What do the Twistors of Roger Penrose and the Geometric Unity of Eric Weinstein and the exploration of one extra spatial dimension by Lisa Randall and the "Belt Trick" of Paul Dirac have in common? Is the following idea a “Quantized” model related to the “Vortex Theory” proposed by Maxwell and others during the 19th century? Has the concept of the “Aether” been resurrected from the dead and relabeled as the “Higgs Field”? In Spinors it takes two complete turns to get down the "rabbit hole" (Alpha Funnel 3D--->4D) to produce one twist cycle (1 Quantum unit). Can both Matter and Energy be described as "Quanta" of Spatial Curvature? (A string is revealed to be a twisted cord when viewed up close.) Mass= 1/Length, with each twist cycle of the 4D Hypertube proportional to Planck’s Constant. In this model Alpha equals the compactification ratio within the twistor cone, which is approximately 1/137. 1= Hypertubule diameter at 4D interface 137= Cone’s larger end diameter at 3D interface where the photons are absorbed or emitted. The 4D twisted Hypertubule gets longer or shorter as twisting or untwisting occurs. (720 degrees per twist cycle.) If quarks have not been isolated and gluons have not been isolated, how do we know they are not parts of the same thing? The tentacles of an octopus and the body of an octopus are parts of the same creature. Is there an alternative interpretation of "Asymptotic Freedom"? What if Quarks are actually made up of twisted tubes which become physically entangled with two other twisted tubes to produce a proton? Instead of the Strong Force being mediated by the constant exchange of gluons, it would be mediated by the physical entanglement of these twisted tubes. When only two twisted tubules are entangled, a meson is produced which is unstable and rapidly unwinds (decays) into something else. A proton would be analogous to three twisted rubber bands becoming entangled and the "Quarks" would be the places where the tubes are tangled together. The behavior would be the same as rubber balls (representing the Quarks) connected with twisted rubber bands being separated from each other or placed closer together producing the exact same phenomenon as "Asymptotic Freedom" in protons and neutrons. The force would become greater as the balls are separated, but the force would become less if the balls were placed closer together. Therefore, the gluon is a synthetic particle (zero mass, zero charge) invented to explain the Strong Force. The "Color Force" is a consequence of the XYZ orientation entanglement of the twisted tubules. The two twisted tubule entanglement of Mesons is not stable and unwinds. It takes the entanglement of three twisted tubules to produce the stable proton.
dark matter is most probably just our attempt to cover shortcomings of existing theories. It may be a make up on a dead body to make it more life-like.
Entonces, segun he escrito en el comentario anterior, El espacio esta ligado con el tiempo, el tiempo esta ligado con la evolucion y la evolucion con la aparicion de la consciencia aqui en la Tierra. Eso hace que la teoría del Big Crunch de volver hacia atrás, hacia los inicios de la inconsciencia ( ¿pero manteniendo la información ?), únicamente se tomaria como referencia a la física del Universo como materia, en un espacio elástico, pero sin consciencia evolutiva. Pero si cabria la teoría de un Multiverso dentro de un espacio infinito. Este tampoco seria un multiverso donde este Universo se repitiera una y otra vez de la misma forma siempre, sino que serian diferentes experimentos. El Big Bang o inflacion, como origen del Universo donde se concentraba, todo lo que es hoy el Universo entero en una singularidad menor que un atomo, es una explicación absurda. No se sabe que hubo antes ( No pueden saber cosas como la posibilidad de situandonos fuera del Universo observable haría que lo vieramos expandiendose como se ve aquí, entonces ya tendrian que poner los bordes de cada lugar donde el observador se situe, aunque sea un lugar que este mucho mas alla de los limites de observacion que hay hoy, como empieza sospechar las ultimas observaciones de James Webb. (¿ se crea masa a medida que se expande ?). Es mucho mas facil pensar que surgio de otra dimension, aunque parezca ciencia ficción, la física cuántica mira de reojo esta posibilidad . . Como analogía, cada uno de nosotros, como personas, somos seres singulares, si, pero dentro de una especie común que ha evolucionado de otras especies, una pieza musical con diferentes melodias. Aquí en el mundo, la consciecia usa el conocimiento para manifestarse progresivamente.Una consciencia pura sin tener un medio donde aplicarse, seria una consciencia abstracta. Es aquí donde las formas se pintan en el lienzo del espacio, como medio para la manifestación progresiva de la consciencia. Un conocimiento sin consciencia nos puede llevar a la locura, a un sin sentido, lo mismo pasaría con una materia, unos atomos y una física sin consciencia detras, seria algo aleatorio, sin orden alguno, ni leyes físicas, sin sentido, basado en la total ignorancia, el caos, intento infructuoso de algo caótico y su desaparicion. La idea de un espacio finito, también es una mala idea. Decir que como el espacio se puede estirar y encoger da la opción a un Big Crunch ( implosion hacia atras, como destino final del Universo que se va encogiendo todo lo que se había expandido, como una película proyectada al revés, hasta volver al principio ), eso es tener una percepción muy limitada de una consciencia que tomaría un camino regresivo hacia la involucion, para crear otra vez otro Gig Bang que se repite una y otra vez. Eso es analizar el Universo con un mente, meramente física, mecánica, una consciencia limitada. El Big Bang mismo es solo una explicación para dar sentido a la expansión del Universo. Esa visión se limita a la incapacidad de no poder observar mas alla. Si resulta que hay mas objetos fuera del campo de visión se quedara en una teoría que habría que cambiar, como empiezan a temer ahora con las nuevas observaciones del telescopio James Webb, el telescopio mas potente que haya podido crear el hombre. Los limites del Universo, está ligada a la teoría del Big Bang y no por el hecho comprobado de que el Universo sea limitado. La limitación esta en nuestra limitada capacidad para ver mas de ese 5 % del Universo observable desde aqui. No se tiene ni idea de hasta donde se podría extender si pudiéramos llegar a observar mas alla de nuestro limite de observación, resultaría que una visión mas amplia daría un significado completamente diferente a nuestra relativa y diminuta parte de nuestra observación, ( a nuestra capacidad psicologíca limitada ) una observación que en comparación con nuestro tamaño es inmensa, pero en comparación con el tamaño de una hormiga es muchísimo mas. La manera como trabaja la evolucion es ampliando nuestra consciencia, pero esta solo se puede ampliar acompanandola de un conocimiento mas amplio, pues como dije, la consciencia sin conocimiento es algo abstracto al no poderla aplicar a algo, asi que si la consciencia es infinita, el conocimiento también lo es. Pero que es la consciencia. El problema con eso es que entonces los astrónomos se ponen a hablar de la religión, de La Bibila, en particular. Yo mas bien, entraría en la metafísica del ocultismo y no soy un gran conocedor de lo oculto, he estado usando la filosofia. Pero si puedo decir cosas conocidas por el ocultismo budista tibetano acerca de la consciencia, sus características, como se ve en su estado, en el inmaterial del sutil, cosas mas propias de tratarlas en un monasterio budista que aquí. ( Aclarar que Buda tampoco fue un metafísico, su enseñanza es mas bien psicologica ). Aquí solo trato de dar mi interpretación filosófica de las hipotesis que hacen los astronomos. Si este Universo fuera infinito, estaria limitado tambien, pues no podria evolucionar hacia algo aun no aparecido aquí. Por lo tanto ha de evolucionar hacia lo absoluto, lo cual tambien seria un limite tal como es nuestra percepción ahora de las cosas y los conceptos asociados, pero esto es debido a nuetra limitada intepretcion mental, por lo tanto, debe evolucionar en nosotros una consciencia diferente que nos permita entenderlo todo de manera diferente, pero con mayor amplitud. ……………………...
Penrose: " We're supposed to be talking about space in the way that we mean space." Maybe Roger should have been a politician. Neither he nor any other physicist has been able to elaborate on what is the nature of a dimension. Not the nature of time or space (that's pretty much a blur in itself), but the nature of dimensions themselves. Why would there be any dimensions? How did they form? Were the 3 spatial dimensions created all at once or did they emerge sequentially? Do lower order dimensions give rise to higher order dimensions? Why would we have 3 or 4 or 11 dimensions (String theory) and not an infinite number of dimensions? We can't really talk about space and time and hidden dimensions without having an understanding, or at least consensus, about what a dimension really is. If a dimension can be altered, like space in the presence of mass, what does that tell us about dimensions themselves? Are there any rules about dimensions? Compactified dimensions? WTF? How can we talk about compactifying something we don't understand? As far as being able to see or measure a 4th spatial dimension, please go back and reread Flatland. Just because we can't measure a 4th spatial dimension doesn't mean it doesn't exist. Even if we can't examine the nature of dimensions, can we at least discuss what we know about dimensions a priori? How do we know that creating dimensions would require enormous amounts of energy per Penrose? At the moment, there is no agreement on what a dimension is. And there is no agreement on what "nothing" is. No wonder we keep floundering about when we try to talk about cosmology. Sabine Hossenfelder just released a video bemoaning the lack of progress in physics for the last few decades because we keep spinning our wheels on unproven (and possibly unprovable) speculation. Maybe the reason for not progressing is because we've skipped over the most fundamental questions about the nature of our universe.
@@autopilot3176 So, how does gravity alter an abstraction when it bends spacetime? Our measurement of a dimension is not the same as a dimension. When Roger says, "...to excite those extra dimensions you need an awful lot of energy", he's not talking about a measurement system or an abstraction. Neither is Claudia when she's talking about compactifying dimensions.
@@triplec8375 You mean when string theorists play with pencils on the piece of paper and they draw an arrow that points to direction that doesn't exist and violates basic geometry? The reason why we can't imagine 4th spatial dimension is because it's not possible to exist. "4D cube" for example. 4D space doesn't exist. They take limited 3D volume and pretend it's one-way street curled up with nothing outside. "Compactification" means changing to a different "manifold" (an abstract spacetime model). And yes it's a "lot of energy". Planck scale ~10-35 m. To test for evidence of the largest of those 10 dimensions we need power of 10^19 GeV and we will reach that capability -- never. Maybe our AI successor will, but we won't be there to witness it.
What if the universe laws that we can experience are not universal? What if these are local? The universe available for us to explore even with the best tools, like Webbs telescope is limited to proably less than 0.001% of the entire universe. Bascially, we are exploring elephant's tail tip and based on that we are formulating theorem on how the whole animal looks like. Is the Planck's constant the same across the whole universe? We would never know. If it is not, then it may be possible for other parts of the universe to display different properties, maybe even different speed of life, gravity forces, dimmensions, etc. Exploring our small neighbourhood is certeinly interesting but there is no certainity that the rest of the village looks exactly like our hut.
dimension we live in is a reaction dimension so what type of dimension are you referring too a reaction dimension or a negative dimension the latter are dimension evolved from and is still expanding into???
You can only change the past by interpreting it differently or blatantly lying. In order to slow time down or reverse it one would need to slow or reverse the vector, repectively, of the velocities of all the elementary particles in the universe simultaneously. Good luck with that!
Time is the distance between differences. It’s kinda hard to explain but everything in the universe shares through relatives so nothing is NOT entangled, everything is sharing just in a different state and sharing differences. Being able to understand and find quantum is not hard just a little farther than our relative tools but close enough in experience. We understand because of the thing we are, mixed variables sharing the same. Life isn’t just because we have a heart, i think that’s what the soul tries to describe. The soul is the self tied to the current variation but once you understand you are sharing with all variables of yourself then you see you could be any version of yourself just by sharing to become. It’s like sharing the mind with the differences and listening to see between dimensions/measurements. The quantum is one field or range but it is a relative point we found that can be utilized in a lot of ways that we can’t currently because technology is shared into existence by experience or reflection. It’s between the differences. So i don’t think we are limited but our beliefs limit us. Our body shares with the life it experiences and that builds the mind and body relative. Another thing, if gods are infinite then why would it be limited? It’s not that one god exists but all differences exist within each other. Kinda like a Rubik’s cube and how it shares to be all states but isn’t all states as one unless you move faster than light but then it would probably be so fast everything looks to be sharing and one thing. Idk but i do like thinking about these things.
@@OnceAndFutureKing13711 very well said, and although I firmly disagree with you, I must admit your reply shows just how much class you don’t have..! And I know so much about you, that I can tell you’re a lefty, and possibly an atheist….! Have a blessed day…!
Yes, there's 1 that's kinda like backed against the one we can see regularly. It's there. Sometimes, you get a small glimpse. You just don't realize. I've seen it only twice. After sleeping the left side of the brain doesn't wake up as quickly. My eyes were open but out of my left eye it was black. My friend was standing there on my left but I couldn't see her, but I could see something else, I asked her to move but nothing but these tiny creatures see through creatures. It's happened twice to myself. So we live in 4 but there are 5 dimensions. This is a fact. Peace ✌️😎. Just sayin always add 1 to be true.
No conocemos el Universo en tiempo real, solo como fue en el pasado. El tiempo transcurria mas lento en el pasado y cada vez va mas rapido y lo sera aun mas rapido en el futuro, debido a la expancion del Universo. Lo mismo ocurre con nuestra evolucion, nuestra mente, nuestra consciencia y nuestra forma física, nuestra evolución también fue mas lenta en el pasado y cada vez va mas rápido, aunque tenga a veces retrocesos, son parte de esta. Nunca podremos alcanzar a llegar o ver el final del Universo, pues a medida que se aleja se acelera, superando incluso la velocidad de la luz. Yo diria que nuestro fisico evolucionara igual, yo diria que tendremos un cuerpo cada vez menos denso, y un Universo menos denso, es mas yo diría que esa escala evolutiva ya existe, pero no aquí donde tenemos una singularidad evolutiva propia y un planeta donde hay un sol y hay una luna y un espacio sutil que lo acompana. En realidad nuestro cuerpo fisico es una cascara momentanea que usamos para vivir aquí, despues de un tiempo, este se deteriora por el tiempo, lo dejamos y volvemos a nuestro verdadero cuerpo que no es fisico pero que aquí esta conectado al fisico donde evolucionan. Las peronas que practican mucho la meditacion, monjes budistas tibetanos, llegan a identificar su cuerpo fisico con su cuerpo sutil y pueden levitar. Algunos incluso, en un momento determido de sus vidas, lo dejan a voluntad e incluso llegan a desintegrarlo quedando en el lugar, tal vez el pelo o las unas. Pero eso no tiene mucho que ver con la evolución aquí en La Tierra, sino que son logros o como se llama en ese lenguaje, Sidhis, a traves de una meditación muy intensa, o esos que viven en una cueva en las nievas del Himalaya, sin comida. ( El gobierno de La India los echo por ser los Himalayas un espacio protegido, pero aun los hay ) Ellos dicen que se alimentan de los rayos del Sol.
first we would need to create AI that would not lie. And it likes to lie everytime it cannot find answers and is becoming better and better at lying. AI training models are basically wrong as the training rewards AI each time it provides answers, not necessary the correct ones. AI is a bit like a psychopath lacking any emotions whose goal is to give an answer that sounds correct and is difficult or impossible for us to verify. I'd say we will regret training our AI models this way one day.
Do we really have evidence for a 4th or is it just a tool of approximation that helps us better rule distances in space? Is it realism or just a placemate reference point? Freeze reality to simplify and I can at best locate infinite sums into determinism then order then back to complexity then decay. Lensing gives a good indicator that topographical view of matter and it's elementary bottom as it traction into higher forms of energy density gets more and more giving me only 3 justified repeating orders of magnitude scaled epochs smaller to larger. Micro to macro. I can see why many only want 2 but browning motion and order if energy or matter occurs and repeats from our best frame of reference. Our mind seeks paradolia of order in a clocklike prenticious view refusing & ignoring its actual sea of entropic decay. Making all tools of approximation in space simple references at best. Gages for what reality is really doing. Greeks axioms are now out determinism. In biology we make must categorize the frame by God's informed consent encoded blueprint order . All this does is hold all info about all it can ever be, it has a state of gates or on/ off but no awareness it's interactivly dependent upon larger scales of order in body & environment. We can't excape 3 way transfer of data in realitive inertia value frame of references. If we pretend a 4th dimension umbrella term evolutionary time window looking in that's obviously a minds eye dialectical vision not realism
@lockpickrogue-yc5wc tools of approximation and ease of access convince is all can find in my half century of witnessing snow on my TV turn cmb . Obviously ancient world calendar counting wars are full of all this. Its a very greeko assyrian babylonian umbrella term usage over a dualistic universe. We hold Jesus in stasis of metamorphosis drag him across 2024 as thermodynamical time decay counting earth's trips around the sun. I know that we find value in it but it does violate all measurement problems. 1st position newton 2nd line eisten 3rd hiesenbergs approach photon all is well until we try to add or subtract measurements then it's yoo hoo woo uncertainty entangled controdidictions so that hurts the evidence of 4th demension time . Hamiltonian occelating feilds correlated with idealized time is very uniform and sensible . Even though its subjective objects inderectly detected and not physical or all idealized..
@lockpickrogue-yc5wc if they could simply stretch time from z axis to y axis and place it on x in space they would've done that day one. To do newtons bucket + machian mass influence then figure a plank time value stretching in higher order of magnitude to make stars * galaxies right. To make thermodynamical time right would undermine such 4th dimension plurisms I think

A quandary no physicist has been able to answer to my satisfaction: Since General Relativity understands gravity as curvature of 3+1 spacetime, this implies a 5th dimension in which the 4 dimensions are curved. Just as a 2D plane can only be curved in a third dimension. Explain please.
We have intrinsic and extrinsic ways to verify that for example Earth has curvature. In the extrinsic way we can look Earth from space and notice that yes the surface of Earth has curvature as 2D object in 3D space. The intrinsic way to notice the curvature would be for example choose a point from Earth, let's say the North Pole. Then draw a circle of radius 10 000km through the Equator. Now 2D-plane geometry would tell us that the circumference would be 2pi*r, which is approximately 62 800km. However, real measurement if done, would yield only 40 000 km, since that is the length of the equator. So this would prove us that we are not in flat plane. In the case of 4D space, we don't have this extrinsic way to look 4D space from the outside. But we have still those intrinsic ways to find out that this 4D space we live is curved. However assumptions about some 5th dimension are not needed to "explain" this curvature. Basicly the point is that the math about curved 4D spaces can be done without referring to other dimensions. This is true for Earth surface as well. We do not need to realize that we have 3 space dimensions to find out that Earth surface is curved.
We call it block universe because of blocked dark matter dark energy We can have time eternal as this dark part is eternal with universe of zero energy

If there is an inside and outside of spacetime then outside of spacetime there is no space separating things so you could take a shortcut that takes no time. Thus entanglement
Awareness is known by awareness alone.
There must be at least one extra spatial dimension. Why?
If Physicists describe electrons as point particles with no volume, where is the mass of the particle?
Can one extra spatial dimension produce a geometric explanation of the 1/2 spin of electrons? The following is an extension of the old Kaluza-Klein theory.
What do the Twistors of Roger Penrose and the Geometric Unity of Eric Weinstein and the exploration of one extra spatial dimension by Lisa Randall and the "Belt Trick" of Paul Dirac have in common? Is the following idea a “Quantized” model related to the “Vortex Theory” proposed by Maxwell and others during the 19th century? Has the concept of the “Aether” been resurrected from the dead and relabeled as the “Higgs Field”?
In Spinors it takes two complete turns to get down the "rabbit hole" (Alpha Funnel 3D--->4D) to produce one twist cycle (1 Quantum unit).
Can both Matter and Energy be described as "Quanta" of Spatial Curvature? (A string is revealed to be a twisted cord when viewed up close.) Mass= 1/Length, with each twist cycle of the 4D Hypertube proportional to Planck’s Constant.
In this model Alpha equals the compactification ratio within the twistor cone, which is approximately 1/137.
1= Hypertubule diameter at 4D interface
137= Cone’s larger end diameter at 3D interface where the photons are absorbed or emitted.
The 4D twisted Hypertubule gets longer or shorter as twisting or untwisting occurs. (720 degrees per twist cycle.)
If quarks have not been isolated and gluons have not been isolated, how do we know they are not parts of the same thing? The tentacles of an octopus and the body of an octopus are parts of the same creature.
Is there an alternative interpretation of "Asymptotic Freedom"? What if Quarks are actually made up of twisted tubes which become physically entangled with two other twisted tubes to produce a proton? Instead of the Strong Force being mediated by the constant exchange of gluons, it would be mediated by the physical entanglement of these twisted tubes. When only two twisted tubules are entangled, a meson is produced which is unstable and rapidly unwinds (decays) into something else. A proton would be analogous to three twisted rubber bands becoming entangled and the "Quarks" would be the places where the tubes are tangled together. The behavior would be the same as rubber balls (representing the Quarks) connected with twisted rubber bands being separated from each other or placed closer together producing the exact same phenomenon as "Asymptotic Freedom" in protons and neutrons. The force would become greater as the balls are separated, but the force would become less if the balls were placed closer together. Therefore, the gluon is a synthetic particle (zero mass, zero charge) invented to explain the Strong Force. The "Color Force" is a consequence of the XYZ orientation entanglement of the twisted tubules. The two twisted tubule entanglement of Mesons is not stable and unwinds. It takes the entanglement of three twisted tubules to produce the stable proton.
Dark matter might be extra-dimensional mass with gravity that permiates our world perhaps?
Sounds good on paper, but not overly useful in the physical realm.

dark matter is most probably just our attempt to cover shortcomings of existing theories. It may be a make up on a dead body to make it more life-like.
Entonces, segun he escrito en el comentario anterior, El espacio esta ligado con el tiempo, el tiempo esta ligado con la evolucion y la evolucion con la aparicion de la consciencia aqui en la Tierra. Eso hace que la teoría del Big Crunch de volver hacia atrás, hacia los inicios de la inconsciencia ( ¿pero manteniendo la información ?), únicamente se tomaria como referencia a la física del Universo como materia, en un espacio elástico, pero sin consciencia evolutiva. Pero si cabria la teoría de un Multiverso dentro de un espacio infinito. Este tampoco seria un multiverso donde este Universo se repitiera una y otra vez de la misma forma siempre, sino que serian diferentes experimentos. El Big Bang o inflacion, como origen del Universo donde se concentraba, todo lo que es hoy el Universo entero en una singularidad menor que un atomo, es una explicación absurda. No se sabe que hubo antes ( No pueden saber cosas como la posibilidad de situandonos fuera del Universo observable haría que lo vieramos expandiendose como se ve aquí, entonces ya tendrian que poner los bordes de cada lugar donde el observador se situe, aunque sea un lugar que este mucho mas alla de los limites de observacion que hay hoy, como empieza sospechar las ultimas observaciones de James Webb. (¿ se crea masa a medida que se expande ?). Es mucho mas facil pensar que surgio de otra dimension, aunque parezca ciencia ficción, la física cuántica mira de reojo esta posibilidad . .
Como analogía, cada uno de nosotros, como personas, somos seres singulares, si, pero dentro de una especie común que ha evolucionado de otras especies, una pieza musical con diferentes melodias. Aquí en el mundo, la consciecia usa el conocimiento para manifestarse progresivamente.Una consciencia pura sin tener un medio donde aplicarse, seria una consciencia abstracta. Es aquí donde las formas se pintan en el lienzo del espacio, como medio para la manifestación progresiva de la consciencia. Un conocimiento sin consciencia nos puede llevar a la locura, a un sin sentido, lo mismo pasaría con una materia, unos atomos y una física sin consciencia detras, seria algo aleatorio, sin orden alguno, ni leyes físicas, sin sentido, basado en la total ignorancia, el caos, intento infructuoso de algo caótico y su desaparicion. La idea de un espacio finito, también es una mala idea. Decir que como el espacio se puede estirar y encoger da la opción a un Big Crunch ( implosion hacia atras, como destino final del Universo que se va encogiendo todo lo que se había expandido, como una película proyectada al revés, hasta volver al principio ), eso es tener una percepción muy limitada de una consciencia que tomaría un camino regresivo hacia la involucion, para crear otra vez otro Gig Bang que se repite una y otra vez. Eso es analizar el Universo con un mente, meramente física, mecánica, una consciencia limitada.
El Big Bang mismo es solo una explicación para dar sentido a la expansión del Universo. Esa visión se limita a la incapacidad de no poder observar mas alla. Si resulta que hay mas objetos fuera del campo de visión se quedara en una teoría que habría que cambiar, como empiezan a temer ahora con las nuevas observaciones del telescopio James Webb, el telescopio mas potente que haya podido crear el hombre. Los limites del Universo, está ligada a la teoría del Big Bang y no por el hecho comprobado de que el Universo sea limitado. La limitación esta en nuestra limitada capacidad para ver mas de ese 5 % del Universo observable desde aqui. No se tiene ni idea de hasta donde se podría extender si pudiéramos llegar a observar mas alla de nuestro limite de observación, resultaría que una visión mas amplia daría un significado completamente diferente a nuestra relativa y diminuta parte de nuestra observación, ( a nuestra capacidad psicologíca limitada ) una observación que en comparación con nuestro tamaño es inmensa, pero en comparación con el tamaño de una hormiga es muchísimo mas. La manera como trabaja la evolucion es ampliando nuestra consciencia, pero esta solo se puede ampliar acompanandola de un conocimiento mas amplio, pues como dije, la consciencia sin conocimiento es algo abstracto al no poderla aplicar a algo, asi que si la consciencia es infinita, el conocimiento también lo es. Pero que es la consciencia. El problema con eso es que entonces los astrónomos se ponen a hablar de la religión, de La Bibila, en particular. Yo mas bien, entraría en la metafísica del ocultismo y no soy un gran conocedor de lo oculto, he estado usando la filosofia. Pero si puedo decir cosas conocidas por el ocultismo budista tibetano acerca de la consciencia, sus características, como se ve en su estado, en el inmaterial del sutil, cosas mas propias de tratarlas en un monasterio budista que aquí. ( Aclarar que Buda tampoco fue un metafísico, su enseñanza es mas bien psicologica ). Aquí solo trato de dar mi interpretación filosófica de las hipotesis que hacen los astronomos.
Si este Universo fuera infinito, estaria limitado tambien, pues no podria evolucionar hacia algo aun no aparecido aquí. Por lo tanto ha de evolucionar hacia lo absoluto, lo cual tambien seria un limite tal como es nuestra percepción ahora de las cosas y los conceptos asociados, pero esto es debido a nuetra limitada intepretcion mental, por lo tanto, debe evolucionar en nosotros una consciencia diferente que nos permita entenderlo todo de manera diferente, pero con mayor amplitud.

Penrose: " We're supposed to be talking about space in the way that we mean space." Maybe Roger should have been a politician. Neither he nor any other physicist has been able to elaborate on what is the nature of a dimension. Not the nature of time or space (that's pretty much a blur in itself), but the nature of dimensions themselves. Why would there be any dimensions? How did they form? Were the 3 spatial dimensions created all at once or did they emerge sequentially? Do lower order dimensions give rise to higher order dimensions? Why would we have 3 or 4 or 11 dimensions (String theory) and not an infinite number of dimensions? We can't really talk about space and time and hidden dimensions without having an understanding, or at least consensus, about what a dimension really is. If a dimension can be altered, like space in the presence of mass, what does that tell us about dimensions themselves? Are there any rules about dimensions? Compactified dimensions? WTF? How can we talk about compactifying something we don't understand? As far as being able to see or measure a 4th spatial dimension, please go back and reread Flatland. Just because we can't measure a 4th spatial dimension doesn't mean it doesn't exist. Even if we can't examine the nature of dimensions, can we at least discuss what we know about dimensions a priori? How do we know that creating dimensions would require enormous amounts of energy per Penrose? At the moment, there is no agreement on what a dimension is. And there is no agreement on what "nothing" is. No wonder we keep floundering about when we try to talk about cosmology. Sabine Hossenfelder just released a video bemoaning the lack of progress in physics for the last few decades because we keep spinning our wheels on unproven (and possibly unprovable) speculation. Maybe the reason for not progressing is because we've skipped over the most fundamental questions about the nature of our universe.
There's no "dimensions". It's only abstraction, a tool, axis of measurement. 3 cover all directions possible.
Uh-huh.
@@autopilot3176 So, how does gravity alter an abstraction when it bends spacetime? Our measurement of a dimension is not the same as a dimension. When Roger says, "...to excite those extra dimensions you need an awful lot of energy", he's not talking about a measurement system or an abstraction. Neither is Claudia when she's talking about compactifying dimensions.
@@triplec8375 You mean when string theorists play with pencils on the piece of paper and they draw an arrow that points to direction that doesn't exist and violates basic geometry? The reason why we can't imagine 4th spatial dimension is because it's not possible to exist. "4D cube" for example. 4D space doesn't exist. They take limited 3D volume and pretend it's one-way street curled up with nothing outside. "Compactification" means changing to a different "manifold" (an abstract spacetime model). And yes it's a "lot of energy". Planck scale ~10-35 m. To test for evidence of the largest of those 10 dimensions we need power of 10^19 GeV and we will reach that capability -- never. Maybe our AI successor will, but we won't be there to witness it.
What if the universe laws that we can experience are not universal? What if these are local? The universe available for us to explore even with the best tools, like Webbs telescope is limited to proably less than 0.001% of the entire universe. Bascially, we are exploring elephant's tail tip and based on that we are formulating theorem on how the whole animal looks like.
Is the Planck's constant the same across the whole universe? We would never know. If it is not, then it may be possible for other parts of the universe to display different properties, maybe even different speed of life, gravity forces, dimmensions, etc. Exploring our small neighbourhood is certeinly interesting but there is no certainity that the rest of the village looks exactly like our hut.
dimension we live in is a reaction dimension so what type of dimension are you referring too a reaction dimension or a negative dimension the latter are dimension evolved from and is still expanding into???
You can only change the past by interpreting it differently or blatantly lying. In order to slow time down or reverse it one would need to slow or reverse the vector, repectively, of the velocities of all the elementary particles in the universe simultaneously. Good luck with that!
Time is the distance between differences. It’s kinda hard to explain but everything in the universe shares through relatives so nothing is NOT entangled, everything is sharing just in a different state and sharing differences. Being able to understand and find quantum is not hard just a little farther than our relative tools but close enough in experience. We understand because of the thing we are, mixed variables sharing the same. Life isn’t just because we have a heart, i think that’s what the soul tries to describe. The soul is the self tied to the current variation but once you understand you are sharing with all variables of yourself then you see you could be any version of yourself just by sharing to become. It’s like sharing the mind with the differences and listening to see between dimensions/measurements. The quantum is one field or range but it is a relative point we found that can be utilized in a lot of ways that we can’t currently because technology is shared into existence by experience or reflection. It’s between the differences. So i don’t think we are limited but our beliefs limit us. Our body shares with the life it experiences and that builds the mind and body relative. Another thing, if gods are infinite then why would it be limited? It’s not that one god exists but all differences exist within each other. Kinda like a Rubik’s cube and how it shares to be all states but isn’t all states as one unless you move faster than light but then it would probably be so fast everything looks to be sharing and one thing. Idk but i do like thinking about these things.

Yes, there's 1 that's kinda like backed against the one we can see regularly. It's there. Sometimes, you get a small glimpse. You just don't realize. I've seen it only twice. After sleeping the left side of the brain doesn't wake up as quickly. My eyes were open but out of my left eye it was black. My friend was standing there on my left but I couldn't see her, but I could see something else, I asked her to move but nothing but these tiny creatures see through creatures. It's happened twice to myself. So we live in 4 but there are 5 dimensions. This is a fact. Peace ✌️😎. Just sayin always add 1 to be true.

No conocemos el Universo en tiempo real, solo como fue en el pasado. El tiempo transcurria mas lento en el pasado y cada vez va mas rapido y lo sera aun mas rapido en el futuro, debido a la expancion del Universo. Lo mismo ocurre con nuestra evolucion, nuestra mente, nuestra consciencia y nuestra forma física, nuestra evolución también fue mas lenta en el pasado y cada vez va mas rápido, aunque tenga a veces retrocesos, son parte de esta. Nunca podremos alcanzar a llegar o ver el final del Universo, pues a medida que se aleja se acelera, superando incluso la velocidad de la luz. Yo diria que nuestro fisico evolucionara igual, yo diria que tendremos un cuerpo cada vez menos denso, y un Universo menos denso, es mas yo diría que esa escala evolutiva ya existe, pero no aquí donde tenemos una singularidad evolutiva propia y un planeta donde hay un sol y hay una luna y un espacio sutil que lo acompana. En realidad nuestro cuerpo fisico es una cascara momentanea que usamos para vivir aquí, despues de un tiempo, este se deteriora por el tiempo, lo dejamos y volvemos a nuestro verdadero cuerpo que no es fisico pero que aquí esta conectado al fisico donde evolucionan. Las peronas que practican mucho la meditacion, monjes budistas tibetanos, llegan a identificar su cuerpo fisico con su cuerpo sutil y pueden levitar. Algunos incluso, en un momento determido de sus vidas, lo dejan a voluntad e incluso llegan a desintegrarlo quedando en el lugar, tal vez el pelo o las unas. Pero eso no tiene mucho que ver con la evolución aquí en La Tierra, sino que son logros o como se llama en ese lenguaje, Sidhis, a traves de una meditación muy intensa, o esos que viven en una cueva en las nievas del Himalaya, sin comida. ( El gobierno de La India los echo por ser los Himalayas un espacio protegido, pero aun los hay ) Ellos dicen que se alimentan de los rayos del Sol.

I am hopeful that AI will help us figure it all out.
first we would need to create AI that would not lie. And it likes to lie everytime it cannot find answers and is becoming better and better at lying. AI training models are basically wrong as the training rewards AI each time it provides answers, not necessary the correct ones. AI is a bit like a psychopath lacking any emotions whose goal is to give an answer that sounds correct and is difficult or impossible for us to verify.
I'd say we will regret training our AI models this way one day.
Do we really have evidence for a 4th or is it just a tool of approximation that helps us better rule distances in space? Is it realism or just a placemate reference point?
Freeze reality to simplify and I can at best locate infinite sums into determinism then order then back to complexity then decay. Lensing gives a good indicator that topographical view of matter and it's elementary bottom as it traction into higher forms of energy density gets more and more giving me only 3 justified repeating orders of magnitude scaled epochs smaller to larger. Micro to macro. I can see why many only want 2 but browning motion and order if energy or matter occurs and repeats from our best frame of reference.
Our mind seeks paradolia of order in a clocklike prenticious view refusing & ignoring its actual sea of entropic decay.
Making all tools of approximation in space simple references at best. Gages for what reality is really doing.
Greeks axioms are now out determinism.
In biology we make must categorize the frame by God's informed consent encoded blueprint order . All this does is hold all info about all it can ever be, it has a state of gates or on/ off but no awareness it's interactivly dependent upon larger scales of order in body & environment. We can't excape 3 way transfer of data in realitive inertia value frame of references. If we pretend a 4th dimension umbrella term evolutionary time window looking in that's obviously a minds eye dialectical vision not realism
there are certain things that implicitly hint towards it, but not explicitly. such as electron orbits, gravitational singularities and entanglement.

We hold Jesus in stasis of metamorphosis drag him across 2024 as thermodynamical time decay counting earth's trips around the sun.
I know that we find value in it but it does violate all measurement problems. 1st position newton 2nd line eisten 3rd hiesenbergs approach photon all is well until we try to add or subtract measurements then it's yoo hoo woo uncertainty entangled controdidictions so that hurts the evidence of 4th demension time .
Hamiltonian occelating feilds correlated with idealized time is very uniform and sensible .
Even though its subjective objects inderectly detected and not physical or all idealized..
@lockpickrogue-yc5wc if they could simply stretch time from z axis to y axis and place it on x in space they would've done that day one.
To do newtons bucket + machian mass influence then figure a plank time value stretching in higher order of magnitude to make stars * galaxies right. To make thermodynamical time right would undermine such 4th dimension plurisms I think
@lockpickrogue-yc5wc our periodic table estimated decay rates used to help us when didn't believe chemistry could produce o2 in earth atmosphere its guesstimates set a frame of reference that now we know it's not exclusive to biology.
Jwst is tasting process in suns that shouldn't be occurring which really should be more publicly discussed on what we should do about refining such dating methods

A quandary no physicist has been able to answer to my satisfaction: Since General Relativity understands gravity as curvature of 3+1 spacetime, this implies a 5th dimension in which the 4 dimensions are curved. Just as a 2D plane can only be curved in a third dimension. Explain please.
It doesn’t imply a 5th dimension.
We have intrinsic and extrinsic ways to verify that for example Earth has curvature. In the extrinsic way we can look Earth from space and notice that yes the surface of Earth has curvature as 2D object in 3D space. The intrinsic way to notice the curvature would be for example choose a point from Earth, let's say the North Pole. Then draw a circle of radius 10 000km through the Equator. Now 2D-plane geometry would tell us that the circumference would be 2pi*r, which is approximately 62 800km. However, real measurement if done, would yield only 40 000 km, since that is the length of the equator. So this would prove us that we are not in flat plane.
In the case of 4D space, we don't have this extrinsic way to look 4D space from the outside. But we have still those intrinsic ways to find out that this 4D space we live is curved. However assumptions about some 5th dimension are not needed to "explain" this curvature. Basicly the point is that the math about curved 4D spaces can be done without referring to other dimensions. This is true for Earth surface as well. We do not need to realize that we have 3 space dimensions to find out that Earth surface is curved.
Imagine a high temperature high density point engulfed by infinite dark space-time of low temperature low density
Life space is emergent then time had a high probability of being emergent
