Oh no! Then we’d never get through all the comments.
Perhaps, but they still haven't tackled the question ---> Are Taylor Swift's thighs increasing in girth from exercise or from the aging process itself?
You could have said 7 billions, we're all in the same boat..
It is baffling to me, that Closer to Truth remains relatively unknown and obscure. My best guess is that it does not lower standards. That looses a lot of potential viewers.
agree ... great content at a hypersonic rate ... perhaps too much content is bad ... but i'm not seeing a drop in standard ...
Just came straight to the comment section for the expert opinions
and me.
Well, if you watch this video all experts would say is a theory they think is the correct one. No more true than any theory in the comment section. Why? Because none of the theories are possible to test
@@emilcioran8873 you win the most generic comment of all time.
Wise choice, 'cause it's common knowledge that the sharpest minds dwell here in the comment section. 🤓

A treasure-trove of knowledge. Best series on RUclips.
Wow it all blows me away!!! So what do I do with this catchy info!!! What has others done??? Tell me!!!
it burns down to the fundamental question : What is reality? is math reality? conscioousness? ... that's why I love this series
Not sure that question has any bearing on the topic of this video.

I've been a follower of Sir Roger Penrose for about 40 years. A great physicist and a superb mathematician. Always straight to the point and always speaks his mind. It was typical of him when he said he was not a fan of extra dimensions, why? ''No evidence'', he said. I have learned much, especially concerning honesty in science from him, there's no shame in being wrong. In short, he epitomises what being a scientist is all about. Live long Sir Roger.
The explanation of space-time by Laurence Krouse at the beginning was the best I've ever heard.
it’s about good analogies
@AK6 can you tell me why? m too lazy to do research..
This is correct.The planets, the stars, the universe, and everything else (is) the anatomy of ourselves including (all) life forms.
This channel is brain nourishment in its subject, camera work superb, audio exceptional, production & editing, engaging narration, pace & tone & not gabbled like so many.. I'm on board for more of the same, thank you..
Robert, these are fantastic educational programs. Thanks
Fascinating. Well done. I subscribed!
“About time”
That blew my mind
🤣
Wow. What a documentary. Thank you.
Interesting and worthwhile video.
I honestly have no idea how this channel doesn't have millions of subscribers from all of this gold material they put out.
If you look at the subscribers the number will be less than 1 million. That’s how you know.
... a beautifully done episode of a beautifully done program :-)
If space and time are recognised as dimensions then why has no one asked what is moving through space and time to make those dimensions exist? I’m presuming here if there was nothing there it’s fair to say it wouldn’t exist?
My answer to this is consciousness is the thing that is moving through space and time...
Could consciousness be a separate dimension that interacts with both time and space, meaning no single one of these could exist without the other two?
Whu not? When it comes to consciousness, anything and everything is on the table.
It certainly could be!!
Great and informative video from heavyweights in the FIELD! Thank you!
How fascinating, to interview all those amazing people. Thank You!
I can't sleep... This channel is too good!
Very well produced. The information provided on Extra Dimensions is very interesting and very clear. Good job.
My favorite subject with my favorite guys! Krauss, Kaku and Nima!! Been following Nima since Particle Fever.
Nice! I didn't know this Nima guy before. What do you think about consciousness? Have seen Penrose's Orc OR theory?
I love those guys along with Sean Carroll.
I respect and like the three scientists you mentioned but when your "favourite guys" have contributed a fraction in one field alone to what Penrose has managed several areas of science then they will become my favourite guys too.
@@SahilP2648 I had seen Penrose on this channel before but I wasn’t familiar with the ORC OR theory I’m watching a lot of videos on it and it’s fascinating! Thanks for shining the light!
@@KrisPucci yes he’s great also! I’ve watched some of his lectures on quantum mechanics
This is content that I actually find pleasurable and interesting to watch!
I have an explanation to 4th dimension:
Considering that the regions between two surfaces were a solid with thickness x, area A and volume V. As V=A.x, we have A=V/x
The volume of the first sphere is V1=4/3pR³ and the second is V2=4/3p(R+x)³.
Thus, the volume of the region between the internal and external sphere is V=V2-V1.
V=4/3p(R+x)³- 4/3pR³ implies that V=4/3p[(R+x)³-R³] implies that V= 4/3px(3R²+3Rx+x²).
As A = V/x implies that V/x = 4/3p(3R²+3Rx+x²).
For x too small, we can consider 3Rx=0 and x²=0, thus, we can have A = 4/3p.3R² = 4pR²
Conclusion: The area of the spherical surface is 4pR²
This process can be applied to the calculation of qbits, since one side of the coin there is a cat, the other a cage and the coin rotating we have both sides: the cat in the cage.
See illustrations and more in my channel.
I was going to prove the existence of extra dimensions--but then things got really crazy at work.
Mood
I’ll like to be in a room filled whit physicists where Kaku is giving a lecture just to see if he’ll still going to say « We physicists! »😬
Kaku is science fiction enthusiast, anyway he is a theoretical physicist, which means he has not proven anything yet.
Is he somehow less a physicist because he’s more “out there” Harvard grad, top of his class, Berkeley PHD etc… Maybe I don’t get your joke.
@@shawnm2113 I've been watching interviews and documentaries with him and that phrase is intrinsically vernacular in his vocabulary. I'm just wondering if he would be able not to say it haha.
This reminds me a funny skit about Frida Kalo (Melissa Villasenor) where they challenged her to paint something other than herself and she kept painting her uni-brow here and there anyways.
@@mitsuomits9077 😂 I follow you now.
@@shawnm2113 Hahaha Thanks
A million dimensions will.make things a million times easier. !!!!!
Thank you for inviting Roger Penrose (and traveling to Oxford). I trust the respected Mathematician's perspective on this, as he would have a more honed understanding of the geometries involved. Some physicists working in String Theory would have a vested interest in promoting Higher Dimensions.
Love CTT. Great subject and very good video. When discussing dimensions, it is so very important to have a consistent definition of the term "Dimension". I struggle with the clear definition of dimension.
Smart words!
Definition is the key to understand.
the word dimension is used in many contexts. in this context it just means the minimum number of basis vectors to describe a vector space. in simpler words the number of parameters needed to describe the postion in time, space etc.
I see it like this. A dimension is simply a world. Extra dimensions is worlds within worlds. It's like putting a box inside a box. So, our universe must be inside another universe.
Great video. All star line up. Thank u for this.
Love this stuff...mind expanding all done here without the use of mind expanding psychedelics...I am passionate about all of these topics ...thank-you for sharing all of this magnificent manifestations of energy in motion electromagnetic wave..
You gotta love just asking these questions, and then to go look for them. Asking things you may never know the answer to.
My favourite topic and my favourite guests all in one? Thank you 😊
When in doubt, Robert Lawrence kuhn is about!!
Michio Kaku's book, "Hyperspace", gave me these understandings back in 1994, A very well written book and I highly recommend it.
I live in the US and it feels like I've been living in another dimension for the past year! 🤪
But that isn't physics its virtual reality, the kind the propagandists have been able to create for thousands of years.
Why
Omg funniest comment on you tube evvverrrr
More like the twilight zone!
In general, the term "dimension" is ANY PARAMETER that must be known and understood to completely describe ANYTHING, physical or virtual or anything else, including mental functions of any kind. If it cannot be left out and it cannot be determined by a combination of other parameters of the object being described, then it is an independent dimension (just like the three right-angle directions in flat space must all be separately given to describe the position and, usually including the fourth dimension time, momentum of an object in comparison to some starting point). This being the case, when such things as consciousness and self-awareness and so forth are being described, which do indeed require understanding to figure out the current and future of some living thing (based on past information stored in that living thing from any and all sources and how it can trigger actions when new events, both internal and external of the living thing, happen), some extra dimensions/parameters are necessary. Thus, is it possible that some of the concepts discussed about multiple "extra" dimensions in our space over the usual 4 (time, x, y, and z) are NOT length-type dimensions, but those that can be used to handle things like mental functions of living things ("virtual reality") instead? If so, they would be MUCH more foreign than time is compared to the space dimensions and require a different set of tools, possibly with minimal mathematics involved, which is totally different from physical science's mathematical-based logic and calculation. I have no idea of how such mental dimensions would be quantified and how their interactions could be defined mathematically more than just statistical averages, not cause-and-effect computations. If this can be properly addressed, our idea of the structure of the universe would be significantly enhanced.
Totally agree with you. You are scratching the surface of what dimensions/parameters are... but regarding space dimensions there are 3 space dimensions and 3 mirror space dimensions, adding time and mirror-time. Where mirror-time is time running backwards. Mirror-spacial dimensions are negative concepts of our Universe. All this implies there is a mirror Universe.
The crazy thing is this.
We consider Gravity a Weak Force because of the limited effect it seems to have on us relative to the mass of the planet.
But in reality, Gravity is such a force that great quantities of it, such as in the case of a black hole can literally stretch the fabric of Space-time relative to the person experiencing the force.
This is why in the Mathew McConaughey Interstellar, they say, an hour here is 7 years on Earth. A person never experiences time as anything but a single fluid motion, because we lack the natural capacity to detect fluctuations, but from the "outside" relative to those in the effect of the black hole, their Space-time is seemingly compact so in the same amount of "Experience" had, there is a lifetime of difference.
If you imagine it like a ruler where time is the length. Artificially stretching one ruler, with gravity, and then having two people walk the same distance forward, say 10 steps. On the original ruler, Person A is farther in time than Person B despite experiencing the same thing subject to the distortion effect of gravity.
I love how at 10:46 he’s shooting some B-roll of him looking around, like he’s looking for those extra dimensions, and a woman walks up next to him and starts looking to see what the hell he’s looking at.
I just imagine myself being high doing these interviews lol
Yea, it's a trip

A time reversal symmetry on a set of subatomic particle fields could have a cloaking affect. This time reversal could establish a shadow view of an effected areas. As more time passes this area could completely disappear.
This is brilliant, great minds brought together
Very nice story . Calm and relaxing presentation. This extra small and fast particals do everything when they are together for the moment and are ruled with speed of light when they are in mass events.... What they are ? I don't know but they are everywhere , in same time make me, ground, water ,you, moon..other dimensions, esoteric worlds.....Only things we can calculate are their density , or , their speed. thanks for video
Present time have three dimensions of space, past time has three dimensions of space, future time has three dimensions of space which gravity could be spread into and weakened (diluted). Gravity may even have role in the formation of past, present and future.
6:15 - Oh God. Ask Michio Kaku a direct question and he almost always replies "Let me tell you a story." Dammit, Physics Grandpa, I just want a straight answer!
*Also, his hypothesis that maybe gravity is weaker because it propagates through additional dimensions, which the 3 particle forces don't propagate in, has already been proven incorrect.* Gravity weakens over distance at 1/r^2, where r is the distance from the source of the gravity, just like the 3 particle forces. If gravity propagated through 4 dimensions, it would weaken over distance at 1/r^3; if it propagated through 5 dimensions, it would weaken over distance at 1/r^4; and so on. Anyway, we already know why gravity is weak; gravity is weak because spacetime is very stiff and requires an enormous amount of energy to curve. *Gravity is the manifestation of the curvature of spacetime, not the manifestation of the amount of energy expended to form the curvature.* That's why the gravitational waves emitted by colliding black-holes 100x the mass of the Sun, _which radiate an amount kinetic energy equal to the Sun's mass_ as they spiral in towards each other, still only compress spacetime by 1/1000th the diameter of a proton. You can then go on to ask "why is spacetime so stiff?", and _that_ is a valid question that we don't know the answer to...yet.
I would be careful to say what we "know" or to say if something is incorrect. We must keep playing with multiple theories on the table, the more the merrier. This RUclips channel is very philosophical about some of the deepest mysteries and I'd say its wise to keep an open-mind, especially within frontier science discovery and philosophy. I like what you have explained about gravity, but just be careful of your confidence or it may hinder instead of help.
Why is space time so stiff? It’s almost as if something is holding it in place
Wow
Fascinating discussion with some of my favorite scientists. Great video to stay informed at the leading edge of science.
So the extra dimension is just a hypothesis to explain how gravity behaves 20:10
Welcome to Philosophy.
You mistaken it with physics.
Depending on how many drinks you have. Maybe 11.
Or just buy a slinky.
Does Information give us extra directions and dimensions? Are dimensions limited to only where particles can exist? In what dimension is my memory, my dreams, my thoughts? In what dimension does my feelings (love, joy, sadness, happiness) exist? Can dimensions also be defined as a place where Information can exist and go?
Excellent illustration from 6:37!
i love that while this was uploaded in 2020 it still feels like something made in the 90s and that’s excellent 😌👍
Idk if we are hard wired to go towards the unknown. Most people step away from the unknown, it's usually a minority that decide to roll the dice of chance and explore it. In a survival situation it makes sense, but I can't help but wonder how things would be if the majority shared the same drive for the unknown.
Referring to dimensions as "extra" seems to put things in a perspective that is disconnected from the very idea of thier existence.
Yes. They are not "extra", they are "irrelevant on a macroscopic scale". Changes in position of a subatomic particle in those dimensions may cause changes in their apparent properties, but those changes are either too small to matter on our scale -- or the changes are so significant that the particle starts behaving fundamentally differently and we interpret that it has transformed somehow, when in fact all it has done is moved slightly in a dimension we are not evolved to perceive directly because that ability was never necessary for survival in the wild.

@@Raydensheraj only if it find them.
the beings that built the tic tac ufo understand these extra dimensions
This is the point I was about to make - there seems to be sufficient evidence now that UFOs exist. These UFOs, if they exist, violate the principles of science in how they move and also the fact that they can possibly be here. So UFOs are the question that needs to be answered - do they exist, or not?
That would be humans then.
They understand slinky, as it's child's play.
Very informative 🙏
Amazing channel man
If gravity can go between dimensions, it could, in theory, transmit information to those dimensions. If information can go between dimensions, then they are tied together, and we could "talk" to a higher dimension that way. That is just wild. It reminds me of the movie Interstellar where they explore the concept of communication into higher dimensions via gravity.
What's the barrier artifact one finds at the innermost dimension where all movement ceases to exist? It looks like the center of a pinwheel and gives off the impression of utter stillness or eternity frozen in place. It's a very anxiety producing place to view.
Buy a slinky & see all dimensions in play.
I love the intro!
So glad I found this Channel--- Uh-mazing content!!!
Yes, there are higher dimensions, but the atoms in your body are vibrating at too low a resonant frequency for you to be able to access them.
Not all of us
This is child's play. Buy a slinky.
I think the reason why movement into other dimensions is problematic or impossible is because like the world around you, - you also are three dimensional and live in the fourth.
It might be something alike the scientist with the koi example; the
fish lived in a two dimensional world.
You need perhaps something analogous to the scientist rescuing the fish. That would sure be something.
Buy a slinky & watch length, width, depth, duration, near, far, light, gravity, vibration, velocity within space-time. All the dimensions you need in action, as it really is child's play.
Robert's voice is too good.
You are a treasure to every thinking human!
We are nowhere closer to the truth than we were before seeing this episode!!
Depends on what you do with the information! Do you have own good qestions? Do you have own good answers? I have every now and then. If someone tells you this or that you still need to believe them! Accept what they are saying! And so on.. It still comes back to you! It always come back to you! What do you think about reality!if you are looking for an answer that will satisfy you, all answers will only do so for ahwile, no answer will permanently satisfy you becaous you are a seeker as everybody is, whell not everybody.

Actually, you don't understand any of it!
Absolutely awesome
I do not believe there are 10 dimension as quantified in string theory…. I believe there is an infinity of dimensions!
There are beings all around us, all of the time. They experience their life at “super-speed”. To them, we are simple creatures who probably appear almost stationary. Imagine how a starfish compares to us, physically and mentally, and you understand. They look like orbs of pure light, bowling ball size, have self-awareness, move with purpose, and are supremely, extraordinarily fast.
i have a photograph of myself visiting an old high school friend. her daughter took it with a digital camera. there were about 12 orbs over my head. my sense was that they were excited that I had been reunited with my friend.
I wonder if the orbs can sometimes be a "person" that has astral projected from another dimension maybe
@@dellawatson1669 honestly, I don’t know. It’s funny; I was just thinking about them earlier this morning. Even though it’s been years, it still bothers me that knowing about them, and even having seen them with my eyes and the brief interaction I experienced, it’s apparently not enough for them to reveal themselves to me again. I guess I saw something I shouldn’t have.
@@caryd67 I don't think you did. That ability sort of lives within us. Some people believe dreams are not just our memories playing like a dvd in our mind. Some believe that our spirit or more like our conscience is "off on its travels" (sorry 🤣) while our physical bodies rest. Some people have certain abilities beyond our 6 senses
@@dellawatson1669 I do believe certain people are wired a little bit differently, and maybe they get the occasional glimpse of a bigger reality, but I’ve never felt like one of those people. Maybe as I’m lying in my death bed, taking my last breaths, the orbs will appear again to release me.
My voice is Heavenly waves very strong and beautiful !

1. Watching and this seems interesting
had another strange thought, of everyone freaking growing up and making such a cool place that the gods had to come and wanted to be here with us. LOL okay that was weird.
superb
Very interesting .
There are many dimentions based on vibatory freqencys. Thoth explaind this.
Telescopes can’t see life on other planets because the strength level of the amino acids and elements are different and that’s what different dimensions are they’ll be 50ft giants on higher strength field planets and we couldn’t see them because the iron element there maybe x10 magnitude and we only see x1 but this is the point of the teachings of the past prophets through the unified fields of peace and love one can be without dimension like a flying star which btw is sime UFO sightings they’re actually people in this form,if you go to a planet you can born yourself there using the amino acid and elements present and you look like a 20ft caterpillar.

Personal experience at the age of 7, has given me a glimpse of other worlds and dimensions. All I can say is it’s real, however no one will believe me. 👽👽👽
Saw a saucer one evening in the 70’s ….been down the rabbit hole for over 50 years. Lue Elizondo is trying to tell us that all this revolves around extra dimensions.
love this show
there are almost certainly other dimensions. i remember reading a book by robert monroe called journeys out of the body. he was able to spontaneously leave his body during a meditative state and he visited many dimensions. he referred to them as "locales"..he met other people from the "past" and the "future" and described time as different to how we perceive it here on earth. i think the possibilities are never ending regarding alternate dimensions , indeed different universes and of course extension of consciousness beyond the body.
"Locales" or "other worlds" or a "different part of the multiverse" would be better descriptions alright for what Mr. Monroe is talking about, that is different realities more or less.
"Dimensions" are a different thing really. It's to do with width, height and depth, etc.
I have a theory that is too open-minded for most people to believe but I believe it with all my heart and soul.
I believe that everything has a purpose, that there is a reason for everything.
So what is the purpose of the other six dimensions?
I believe that the other six dimensions are at the same scale as our dimensions and they contain the very machinery that creates our reality, that is holographic projector arrays.
I believe that we live in a holodeck complex super-structure (like from Star Trek).
I am the most open minded person on planet Earth at the moment and the funny thing is, I'm correct 🙏
@live life: so he says. he's there to sell books.
@@PatrickRyan147 you don't have a theory, you have an idea. what does your theory predict? how will you test it?
@@cosmikrelic4815 The big bang is a theory. Simulation is also a theory. Then you have the holographic universe theory. My Holodeck theory is the natural corollary of that theory.
The holographic universe theory doesn't work because it doesn't properly answer the question "Where are the projectors?". They say "Outside if the universe". Impossible! They have to be much closer, hence the holodeck theory. The projectors are hidden in (are made of) the other six dimensions. That is the purpose of the other six dimensions.
But you can call it an idea if you want. It's just semantics 🙏
There is no such thing as "extra dimensions" I think the proper term would be multi-dimensional
Semantics
