I'm confident that in one of these parallel universes I actually understood all that he had said.

The ability to tell something which is so complex yet so easy to understand... Respect.

He’s one of my favorite scientists. He just knows how to explain complexed concepts in a way that the layperson can easily understand. We need more people like this.

In a parallel universe, kids have trading cards not of baseball players, but of scientist, and Max is the most valuable card. Respect.

this has to be the best parallel universe video I've come across. .. in this universe

This guy makes these things understandable... I wish I heard him when I was in school.

Now this is a dude I’d want to sit down for a coffee with

Just passing through your universe and leaving a comment on my way through. Have a nice day!

Who else has found this on their recommend in 2020?!

According to what he's saying, physics does not have unified definition of the word *universe.* Some people, such as Michio Kaku, speak about other universes in terms of universes that exist in other dimensions parallel to ours. Tegmark is referring to other universes as areas of space outside of our reach, but in the same dimension.

I find Max, an enjoyable person to listen to. As a NATIVE American Indian(Eastern band Cherokee), It's nice to hear a scholar who trys to explain something, that we are made fun of, not only. For believing but knowing... To me I was raised with not just believing but knowing our relationship with what others call parallel universe.. It's our way of seeing and knowing...that it is real and exist to us ( NATIVE Americans)... It's nice to see science stating ancient knowledge....

My dreams are so like real life that I swear I am in another parallel universe living the same life!

I Just love the way Max Tegmark talks and smiles and tells this with passion.

This man has an incredible ability to explain these concepts in a way that is easy to understand. I'd love to take one of his classes.

I fully enjoyed this lecture by Max Tegmark.

Max knows his stuff while explaining it in a easy to digest manner even a unscientific person like myself can understand... 🤔

Max is awesome. I highly recommend his book "Our Mathematical Universe" where we goes into much more detail on these 3 levels of multi-verses, as well as a 4th level.

I love this guy. He puts things in an understandable way. I think I am prejudice in reverse, though. His minor facial ticks make me immediately feel he's super smart and worth listening to.

I wish this guy was my physics teacher

You could wake up in a different universe everyday and not know it

Thank you for a very interesting discussion of the possibility of the existence of parallel universes from a strictly scientific perspective. To broaden the scope of the vision, I'd suggest that the scientists working in this area also examine the ancient classics and philosophies for clues into the existence of parallel universes, and how the concept of the multi-verse was presented at that time. In my view, a thorough review of the classics and ancient philosophies is important for one reason: it might give the scientists new clues to see the problem differently and possibly to investigate the problem in a different way. In the search for truth, there's no reason whatsoever to discard other sources and traditions of knowledge, be it philosophical or mystical. One place to start could be a careful review of the Tantric theory of loka. Loka is a Sanskrit word that denotes a plane of existence, a sphere of the macrocosmic mind. Tantra postulates the existence of multiple lokas, the vast physical universe being the crudest manifestation of the Cosmic Mind. There are several progressively more subtle lokas or universes or planes of existence in Creation, each with its own attributes and laws. In my opinion, the most thorough and potentially scientifically compatible explanation of the theory of lokas is by the 20th century mystic and scholar Prabhat Ranjan Sarkar. A supporting idea, also by the same person, is the hypothesis of the existence of Microvita, the fundamental particles of consciousness. There's no harm in reviewing these philosophical and mystical ideas to see if they could be followed up scientifically, or help in any way to illuminate new directions in the search for multiple universes.

Always loved Science, one of my favorite classes in High School. So many interesting things to think about, the only thing that held me back from it was my math skills, they sucked or else or could have easily have seen myself becoming a guy like Max Tegmark,100% Science nerd.

Excellent explanation. For such a profound talk his delivery was quite straightforward!

AWESOME WORK MAX.. THANKS FOR MAKING IT UNDERSTANDABLE FOR US 2 SEMESTER PHYSICS STUDENTS.. A+

2:22 - Gets from Robert De Niro to Bruno in one sentence. I'm impressed!

Max Tegmark may just have made one of the most profound statements ever.

I love this guy. He is smart wait smart is an understatement this guy is an epic genius. Love the way he explains everything. Hope to see him soon.

So well explained. Wonderful. Connecting of obscure dots which do appear to be philosophical in general, has given food of thought and munching. Best on the subject.

In all the parellel universes I came from this universe is the most unreal.

I think that parallel universes can be over top of one another in the same space, in higher vibrational dimensions, rather than somewhere else & other individual manifestations of our personal lives should be called alternate universes.... Parallel universes are permanent, but alternate universes are temporary, around as long as needed & then dissolved....

I believe in Perpendicular Universes.

Outstanding explanation and scientific view of where we are, and what is still to discover!!

String theory is not proven, however it is favored because of all the questions it would answer and make logical if it is correct. That by no means it is correct, but the prospect seems good for it. The problem with string theory is the sheer difficulty in testing it, as it deals with multidimensional effects. By the very nature of something being outside our dimension, we cannot measure it. However, we can test the things it predicts that would be measurable in our dimension, but this is the reason it has not been proven/disproved yet. So far, we have been unable to disprove it by these means, but the difficulty in testing is the main reason many scientists reject it. The wave function collapse basically screams that multiple dimensions must exist, but we do not know what happens to the 'other' realities when a wave function does collapse, but reality forking into multiple dimensions is a model that works, but we don't know if it's accurate or not. It would prove the concept of the philosophical 'free will' once and for all though.

Who's here after the recent news on 2020? THIS IS SO INTERESTING TO ME

My father is dead and I terribly miss him. Hope there is a parallel universe where he is still alive 🤞

Max is one of the best minds of our time

Could be that the constants in the universe are fine-tuned to life because of life actually can happen from a pool of possibilities and of course, if we just happened when we look to the constants they HAVE to be fine-tuned, otherwise, we wouldn't even be able to study it... So, from our perspective they are perfect for our existence, if not, we wouldn't exist in the first place. All other configurations coexist... it's not that we are special it's just that we can be so here we are.

The sheer number of Galaxies, stars and planets dictate the exact replication of existing realities, probably many times over. All my other selfs agree with me, completely...

Mr. Tegmark, I have a suggestion: As you know, astronomer Vera Rubin, worked with Dr. Kent Ford, and he built a very sensitive spectrograph that they used to measure the speed of the stars around the center (black hole) of each spiral galaxy, starting with Andromeda, the closest to ours, and then 200 more. The data obtained showed that the stars rotate around the center of the galaxy as if they were attached to a turntable, which means that each star rotates the same number of times around the center of the galaxy, which contravene Newton´s Law. Based on this discovery, I suggest to add tow more forces to the four that we already know, so now we have six: 1 Magnetism. 2 Gravity. 3 Weak atomic force. 4 Strong atomic force. 5 Weak interdimentional force. 6 Strong interdimensional force.

I have always loved loved loved Tegmark!! The cosmologists, quantum physicists are my rock stars NOW!!!

Fantastic , this is outstanding , absolutely interesting

This is a great video and the idea was well presented. I was expecting pseudoscience but got something grounded in reality instead. Good shit

Thank you for this. Entertaining, accurate, and helpful.

This stuff really REALLY blows my freaking mind. I can't wrap my head around it. If I start thinking hard about it, I literally start getting a headache.

Imagine this guy playing lead in a time travel movie. Oscar

The problem with parallel universes is that everyone who understands the ideas themselves knows that all 3 types "exist" whether we have machines that can "prove" them or not, and whether we are comfortable with the ramifications of that discovery or not. Thus, the ambition and the race is to find a way to design an experiment that could, in fact, falsify these ideas... and have it fail to do so. These are not new ideas. Certain practitioners particular esoteric arts have used them to affect "our reality" in very real ways for many thousands of years. The problem is that while these arts can be effective, they remain outside of science until that crucial scientific experiment is devised and run. Until then, the arts remain beyond the line of mystery, and it's in the best interest of all that the line be moved outward to include them. [You are seeing this sentence right now because that line was moved outward far enough to include "spooky action at a distance" i.e. quantum mechanics, that also turns out to be how stars actually work, by the spontaneous teleportation of atomic particles.] The frustrating part for scientists is that the practitioners of those arts are of little use in designing the experiment to explore them. This is not due to any disingenuousness or jealousy on the part of the practitioners, but because the functions of what is beyond the line of scientific discovery operates on different mechanisms than those same techniques would once they are within that line. The scientist requires a machine, an objective component. The artist operates on subjective super-consciousness. These are not in opposition. They are different. In the TV show "Medicine Men Go Wild" one of the twin doctors who hosted it described his frustration with that difference. They personally saw how a practitioner linked the activity of ants in a jungle to an infection in a girl who lived there -- apparently the worst kind of superstition to someone who is unfamiliar with emergent properties of complex dynamic interactive systems -- and yet in altering the state of the ants, the state of the girl was well resolved. His complaint (approx): "I can see the results. I can measure the results. It worked. Still, I don't understand what the activity of ant colonies has to do with a jaw infection in a teenage girl." He had done enough of this kind of research to recognize when there was science to do and a wall it had run up against; and to look not to disparage the wall, but to try to figure out a new way to apply the science. This is how great discoveries are made. In another episode, the same doctors made this observation on such processes that had successfully gone from art to science in another case (approx): "Today, we used a modern medicine derived from a folk remedy in China, to cure a disease in a child in the jungle of Africa." They understood how such apparently nebulous connections can lead to reliable outcomes for the betterment of all.

Excellent video. Very interesting and worthwhile, and a must see video for everyone.

Excellent. Such noteworthy thought.I love it.

Maybe. But there may also be other dimensions and realms hidden from us.

He's studied this topic long enough and has a sufficient background in math and physics to know what he's talking about. It makes the multiverse far more believable when we keep finding bits of evidence that supports the concept - and that's exactly what is happening. For example, the WMAP 2008 and Planck 2013 missions from NASA and ESA have calculated the shape of our universe and found that it is extremely close to "flat", meaning that it may very well be infinite. Thus, we can only see 14 billion light years of this infinite space giving weight to the idea there is far more out there, perhaps multiple instances of spatial inflation that produced another "pocket" universe like our own.

I love the the idea that platonic forms are alternate universes in level four universes

The way these Mandella effects are, one could argue we jumped over somehow into level 1 parallel universe. Where history is a little changed.

I often find it difficult to focus on what he's talking about thinking to myself 'does this guy have muscle in his nose?'

Max Tegmark is Ted Bundy from a parallel universe that pursued physics.

5 years later, I entered the chat. Really interesting 😍😍😍

That is because this gentleman who I admire, is one of the best . He talks passionately about physics, he loves it . He makes me to love it too. I like him

HE JUST EXPLAINED THE IMPOSSIBLE SO SIMPLE ! RESPECT SIR 😎👏🏻👏🏻👏🏻

Perhaps the parallel universes are based on action and equal and opposite reaction. We get a parking ticket in one universe and we do not in the other. Then there is one where we get a parking ticket and beat it in court and the one where we get the ticket and lose in court and so on. Perhaps each parallel universe is the result of the universe putting itself in balance. Based on this "action and equal and opposite reaction, the universe will always be creating new universes in order to attain the balance. Also, the people that we share this reality with may not be in our other reality or realities. We just use them to assist in the balancing act, when we need them. This may be the reason the universe has been expanding exponentially since the Big Balance, I mean the Big Bang. A sort of expanding universe and duplication based, on equal and opposite reactions. Every time it changes it must correct itself. Like a cell splitting in two and so on and so forth.

never knew a scientist to be this handsome

About 5:16, he says the equation for water has 3 solutions: solid, liquid, gas. Actually, more than 3: there are exotic ices, typically due to draconian pressure; often denser than liquid water. There is also supercritical fluid (too hot to be a liquid, too high-pressure to be a gas, so it is not really either); and at high enuf temperature, water molecules start to dissociate.

Excellent speculation concise.

Fascinating talk mixing physics and philosophy ! Thank you Sir !

I have experienced that things that happened when I was at school have changed. Some people that I graduated with, 50 years later weren't recorded as being in my class. But I remember them very well.

The whole is greater is greater than the sum of its parts.- Aristotle. What is the whole or 'synergy' in the case of many universes? This video makes me think of John H Holland- “Experiments unguided by an appropriate theoretical framework usually amount to little more than ‘watching the pot boil’… We need experiments to inform theory, but without theory all is lost.”

I have read all the comments and watched this video. I think the main the for us all is to keep an open mind.

Good evening Mr.Max Tegmark and Serious Science. Thank you so much for your good information.

Listening to extraordinarily intelligent scientist will make you feel smarter.

Our universe doesn’t have any parallel universes, but there are universes out there that do.

our universe is based and built from consciousness..... our science proves this with the Slit experiment ( wave. vs particles, change when someone views test or not)....so that's why the reality is the way it is.

Let me ask you a question. If parallel universes are possible because of the different choices, can different universes collide in one or more dimensions if one of the forthcoming choices tend to bring the state to same result?

Excellently explained. Thanks

I by mistake clicked on this and watching this. There is a possibility that my parallel self might not have clicked on this and searching some other videos 😂.

Who is watching this December 2019 ? 😍

I had an idea before that, There's a huge simple universe with only a few quantum laws, and somewhere in it is our oasis with physics.

what is the 10th to the power of 500 or 10^500.....am i correct in thinking that this equates as a whole number to be, 1 followed by 500 zeros or in other words, 500 x 500 and thats how many parallel universes they calculate

Very interesting presentation.

WEL said max ......black holes form other universes,.ours came from a black hole singularity from another universe and this will repeat eternally.

you just need to speak with your wife to know there are parallel universes

My theory is that deja vu is your actions that you did in a parallel universe. So basically, there is 2 versions of everybody. You, and your parallel verse self. There are 2 versions of everyone. Now you all do the same actions, just in a different order. So in the parallel verse, you still live where you live, you still go to school where you still went to school, etc. So the reason you get deja vu is because you’ve already have done it in the parallel universe, just haven’t done it yet here. The second version of you has done everything you’ve done, just one more than you. And every-time you catch up with the one more your second version has done, another appears. And that is why you get deja vu.

Mr. Tegmark makes this very nice for layman. As a chemical engineer and pharmaceutical scientist, i am undoubtedly a novice in physics. Nonetheless, gravity is still just a theory(and certainly a damn good one btw). There remains a possiblity, albeit a slight one, that gravity may be something else. Many scientific discoveries were made by accident looking for one thing and finding something else altogether unrelated. For example Viagra and penicillin. My opinion is that we may one day stumble upon an ability, beyond our current comprehension, to manipulate and undeniably define gravity without question what this invisible super power is entirely. But as it is, we stand upon the house of cards built upon the theory of relativity. The weight of the entire universe rests upon the house Einstein built. Gravity, recognized as a natural phenomenon, affords us a method to assign order to the physical world as we perceive it. Also, as long as our math continues works out, we properly accept theory as fact until otherwise disproven. However, we could be in for a doosy, if or when any of our mathematical constants changes or breaks down, our entire perception of the physical 'world' could change dramatically. Edit for misspelling 5-24-2019

The other universe ate my homework.

In another universe the Twinkie cake is at the center and filling is on the outside.

Mandela effect. Loved this, brilliant explanation.

Glad his guy knows everything. Very soothing

I see other universe while i meditate, its real

Shit! This video just opened up a new perspective of life. This dude deserves the noble prize! ( and a like)

There is actually no difference between a 1st and 3rd category parallel universe. These universes would not be causally connected, so there would be no way to empirically test, if it is a universe beyond our cosmic horizon (1st category) or it is just another quantum state of our universe (3rd category). This means we have to apply the Principium Identitatis Indiscernibilium (principle of identity of indiscernibles). Both would be effectively the same. Both theories imply that the world is infinite, which means that everything that is possible, necessarily exists. However not everything that exists can be empirically perceived, which makes the visible universe finite.

Why would this fascinating video have a relatively high number of "thumbs down" comments? Religious fundamentalists?

i am high and he is blowing my mind. can anyone relateeeeeee

7m30s - You have to love how he says LUCK and MIRACLE and stops short of saying Creator and says "Or what?' I'm always fascinated by scientists who like to quote Einstein but forget that he himself never believed that humanity was just some random occurrence.

I have dissociative identity disorder and as a kid I use to think about this stuff. Some of the mental symptoms I experience I swear I'm tapping into parallel universes. Some of the memories I have of my past are fictional but so realistic I wonder did they take place within another parallel universe? What also happens to me at times, I've actually read about it in paranormal books and the symptom that I experience I will explain. One time while exiting a convenience store I began to experience the symptom as I walked past a candy shelf. A quick flash of silver color light happened. Sometimes this silver light lasts for some moments and it brings on a headache while other times like in the convenience store it happens quickly and there is no discomfort. All of the surroundings become sharp and brilliant to describe. When I was young and first began experiencing these symptoms, it shocked the living daylights out of me. I still remember a time when I was very young and it happened. I was on another earth I thought. Seriously I do remember much of my past like it had just happened and it becomes embedded into my memory afterwards and becomes difficult to forget. While walking past the candy shelf I noticed necco wafers but did not stop and continued exiting the store. Right before exiting the store I wanted something to munch on and so I turned and went back over to the candy shelf to grab the necco wafers. It was during these moments when the sharpness and brilliancy ceased and when I looked for the necco wafers they were not there and the other candies present looked different from before. This happens to me so many times in life I'm actually use to it. When I tell people about my experiences I'm just a kook they think. I also met schizophrenias during my life and they too are tapped into parallel universes. The voices they hear are from other schizophrenias from other parallel universes we theorize. But here too we are kooks when we tell people about it. And that is why some schizophrenias go mad and crazy at times, because nobody believes in them except for the others they meet in their heads from parallel universes and they too are mad and crazy because they are schizophrenia and nobody believes them. Unfortunately we also experience illusion which can bring on delusion and yes that is when we can go kooky. Chow.

I must the other version in the parallel universe... finally understand this complex topic😁

There is a better video, in a parallel universe

Does anyone else see Michael Fassbender in this guys face and mannerisms?😂

The message i took from this is now trying to imagine all the other counties history classes and the psychological implications...

This video is sublime.

Why is there no mention of the type IV parallel universes?

It seems that our knowledge has highlighted how ignorant we are of the universe, and current trends suggest that future physics, if not other subjects, will reveal really "weird" fundamental laws and behaviours of matter/energy/spacetime..

Trivia fact: Hugh Everett is the dad of Mark Everett (Mr. E) - the singer of Eels. Also, I think we probably live in a huge holographigic/non-local brain. I.e., a massive quantum computer. We're just presently experiencing one of literally infinite possible lives. The probabilities are limitless. A huge, interactive choose-your-own adventure, maybe. Idk. (But if so, is a trap? A regurgitative prison-machine? Idk.)

0:53 imagine the exponential type advancements we’ve made now, but allowed billions of years to develop across the universe let alone what’s outside our observable universe
