Don't forget Asimov's 1st law of futurics: what has been happening will continue to happen. What has been happening? Constant revisions upward of the size of our universe and the numbers of stars and planets in it. The discovery of other universes would just be par for the course.
I've seen many of your videos, and, to the best of my knowledge, this is the first time I've heard you say unequivocally that the "multiverse" hypothesis is quite possibly not correct (as compared to should be, probably is, very well might be, etc.). That's good to see/hear!
Don't think of it like that. The inflection he provides to the ideas is mostly for entertainment, I believe. It doesn't change how the ideas are viewed. In other words: it could be. He believes it's true, but many many others don't.
There's a big difference between how he talks about the multiverse when speaking about his personal opinion on the subject and when he's presenting an educational video about the subject as a whole. He might be convinced the multiverse exists but he knows the evidence to prove it isn't anywhere close yet. Therefore, when teaching he will give the educators answer, not what he personally thinks. In other words, he does what most scientists do, seperate his own opinions from what he can prove.
There's a reason particle physicists and really physicists in general, dislike string theorists and inflation theorists. Steven Weinberg in his later years called string theory a non-quantum theory. And Roger Penrose calls string theory "fashion" and inflation "fantasy and faith", and he's done so to Carrol's, Greene's and Suskind's faces. Many renowned physicists who once enbraced strings and inflation have walked away from that and call it nonsense. Physicists like Neil Turok, Paul Steindhardt, Matthias Albrecht, and Sabine Hossenfelder, who are in at least as impressive standing as Carroll, Greene, Guth, Linde, Starikovsky and Susskind, disagree. And as for Witten, we need a match with Eric Weinstein, in what would be the match of the early 21st century.
I think that our priority should be surviving as a species and eventually we will understand the world around us and this is observable and measurable. The rodents we are descended from could only understand the world around it to a certain degree and as we evolved (survived) we began to understand the world around us. Over hundreds-of-millions of years evolution allowed our brains to develop and this happened without our consent or our conscious effort. I don't think we can find the answers we're looking for, a force greater than us will grow our understanding if only we can survive and this happened, we see it happened when we look into the past. Survival of the human species is the key to understanding the questions we have today. Write the questions down, record them in history, and spend most of your efforts making sure humans can live millions of years.
As a Christian, I’m often irked by scientists who parlay their specialized knowledge into an anti-Christian career(e.g. Dawkins, Krauss, Sagan, etc.). While Sean has wandered into the fray, I find him more genuine than the aforementioned. Concerning this topic, I found Lee Smolin’s book “The Trouble with Physics: The Rise of String Theory, The Fall of Science, and What Comes Next” very illuminating.
Sean is describing the planet of Krikkett, from one of the Hitchhikers books. At the start, it didn't go well for the rest of the galaxy when they found out that there was more than just their planet in the universe...
in my opinion, beyond super symmetry unification energies, energy itself becomes a dimension of the multi verse. If it interacts with any universe, then such high energy dimensions become hidden dimension of the interacting universes.
Love Sean Carroll - For me The Multiverse is just an excuse for the dead end reached by fine tuning. If we are really in a multiverse, wouldn't it be concluded that that the Multiverse be itself in a multiverse. I'm happy with one universe with God living outside.
Assuming another universe exists and has different law of physics, how this different law of physics affects if one of us visits the other universe (assuming we can visit another universe)?
While it's fun to think we could be superheros or false Gods with powers the inhabitants didn't have, it's most likely that we would also be under the control of that universe's rules, with fun, shocking or even fatal consequences. For example, if a being from a universe without gravity found itself here they couldn't simply ignore gravity and fly, it's more likely a body not used to having a crushing weight pulling it down would be in a spot of difficulty.

What “triggers” a multiverse to exist? I believe only time travel can trigger multiverses. Something would have to have changed in the past (or future even?) to “trigger” or initiate an additional parallel universe(s). Because how can there just simply BE multiverses? What would “cause” there to be multiple “me’s” or “you’s”? So unless someone from the future has the ability to time travel, I don’t believe there are currently multiverses. Unless we can prove time travel 🤷♀️ And I believe the past doesn’t exist. Once we live into the next “now” (next moment), the previous now is gone. It’s done. No longer exists. Therefore, nothing to time travel back to. Therefore, no multiverses.
Time Travel, actual Nuclear explosion, (refer to Oppenheimer's utterings, post the experimental Atom Bomb explosion in USA) Multiverse are mentioned in Hindu Sanskrit texts, written thousands of years ago. These are new to modern science.
Sean Carroll is great a explaining difficult subjects. But that tie is just too much. It's a serious fashion crime. An atrocity committed upon retinas everywhere. It's mesmerizing, like a slow motion train wreck. Perhaps a cry for help?
Yes, let's stick to observable things. I laughed out-loud. Is that why astrophysicists cling to dark matter and dark energy? Because they're able to observe rapid motion occurring to stars and galaxies but can't explain it? In 1919 Einstein proposed gravitational waves would result from the collision of bodies of great mass like neutron stars or black holes. Ripples would traverse throughout spacetime as a result. If infinite multiverses or parallel universe branched off of our reality it was proposed gravitational waves would be affected traveling through the missing or hidden mass. According to the theory the mass in the parallel or multiple universes would exert an effect upon the gravitational wave causing them to slow down the further they traveled. They proposed if gravitational waves lagged behind the speed of light it would be empirical evidence multiple or parallel universe overlapped our universe. If GWs lagged behind it would be evidence of multiple universe. If GWs travels at the speed of light without slowing down then it indicated there is no such thing as multiple or parallel universe. If gravitational waves traveled slower than light it would be solid evidence this universe was just one out of countless universes. If gravitational waves didn't travel at the speed of light it would explain why the attributes which make up this universe was finely tuned. It would explain why our universe has existed so long without winking out of existence moments after it began. It would debunk God. The multiple universes would each be random occurrences, set forth in motion after the big bang. Slow gravitational waves would be the holy grail for atheists and their evolutionary cosmology. So, what did LIGO measure? Every one of the GWs they measured traveled at the speed of light. Researchers went over radio telescope data and determined at the same time and locations of gravitational waves they found a spike in electromagnetic radiation, gamma rays or X-rays. There was no lag between the gravitational waves and electromagnetic waves. Indicating the gravitational waves were not affected by mass in hidden or parallel universes. Multiple universe appear to be science fiction at this point. It's back to the drawing board I guess.
Shouldn't this be louis carroll. Math proves a multiverse is necessary and the only way to explain time and probability. probability, time and quantum mechanics clearly exist and they would not if multiple time line universes didnot.
Probably a dumb question but that won’t stop me from asking .... doesn’t eternal inflation and the multiverse violate the second law of thermodynamics ?
@@TheGreatCourses I understand that , but I am asking how do they explain all this extra energy required in Inflation/multiverse ? I never have heard this explanation from its proponents . It seems to me that they need to explain that but it never seems to be addressed . I’m just saying this would appear to be a huge problem .
@@eddiebrown192 I'm not a card-carrying multiverse proponent but if, you are seriously interested in this and actually want an answer, then Sean Carroll has an excellent book called Something Deeply Hidden which goes into this question and other similar questions that a non-professional physicist (but with an active interested mind) would immediately have and in quite some detail. Basically, there are reasonable objections to the multi-verse idea but things like entropy, probability and conservation of momentum and energy are all compatible with it - as you would expect if someone like Sean Carroll is advocating it. Having read his book, I went from being a skeptic to being able to understand that it's a reasonable and valid idea and is not a waste of my time like string theory.
How does inflation violate the second law? The bigger the universe, the greater the entropy.

This is not true and is dumb. It shows how one error leads to anothrer. Rejecvting henesis starts the errors. As Twain said heaps of conjecture on a sand of fact. Or something.
Soon ar later, scientists will be like religious leader. Bring their own 'bible' to proof their god is the correct one 😅. What they get are believer/follower, not science break through.
I think the multiverse is real. I met a man in person who I swear was me and he was pure evil end up rapping someone. If you seen us we were twins. Dad sad I didn’t have twin
Every possibility is played out in the multiverses. Why can it not be played out in every galaxy. If there are 2 trillion out there, surely every possibility is accounted for. Why think beyond our own universe, when these possibilities could be happening in our own back yard?
Because there are many more possibilities than just a few trillion. Even a deck of 52 cards can be arranged in 8x10^67 ways. That’s way more than the number of atomic particles in our universe.
Sounds like there are other attributes of reality that we have potential of exploring ( Example spiritual world, You quite literally Explained about half of it). Think bigger!!!!!!😤💪🤗 how would someone explore the stuff you're talking about. Listening to you talk is like the people in 1400's, Questioning the shape of the Earth Flat or other. If Christopher Columbus sailed the ocean will he fall off the planet? That's the best way I explain it.
Who says that a counterfactual constant of nature COULD be different? If Sean Carroll was tall, disinterested in physics, and a basketballer... he could have been a basketballer!!! If i was handsome, an actor and George Clooney i could have been George Clooney! This is in no way science.
11:40 But, if the universe is really infinite, then the amount of energy in "our" universe, is a dust mote in a sunbeam.... And I could just see a bouncing universe being created and instantly self-destructing, only to be reborn again in a fraction of a second and repeating. That would be interesting.
I believe in a multiverse with multiple dimension... Only hope that beings with higher levels of intelligence will stop observing us and start helping us. We have to be one of the Lowest and worst dimensions with war and Violence. We definitely need help.
Sean Carroll is so awesome and the way he explains the Universe and life seems really easy for him* ..i think Sean Carroll is from an advanced planet and he came here to try and explain all of reality to us, :)
Hi Sean, thank you so much for your kind feedback! We truly pride ourselves on our professors and the depth of our content and are very glad you're enjoying our offerings. Thanks for being a fan!
In your intro you said that the multiverse was not observable therefore it was impossible to prove. You can say the same thing about evolution. We have never witnessed an evolutionary transition in the history of mankind. You may find a bone, or a dinosaur egg. But that doesn't mean anything.
They cannot explain big bang. What caused it? Where did all that energy come from? If one calls the universe the true power of God moreso than the miracles and superstition then everyone gets upset.
Can you not understand that multiple universes is a contradiction in terms- rather like the idea of more than one unique thing? Universe m-e-a-n-s *only-one*. Either that or it means nothing. If you have in mind something that is not only-one, then pick another word- a fresh fantasy. If there are more than one unique thing then(neither* of them is unique. Just chuck away universe or multiverse and speak only of verses. Go for that and it will become clear to you that verse(uni, or multi) holds no significance for you whatsoever. You have no idea what a 'verse' is; for you it is no more than a word that evokes no associations whatsoever. multiverse= lots of somethings but lots of exactly what?-you have not the slightest idea. Just recognise that fact. instead of multiverse go for wordyword, it comes to e-x-a-c-t-l-y- the same thing. Sure there are any number of wordywords; so what? You have no direct immediate personal experience of any of them; you simply keep repeating a mantra: wordyword, wordyword, wordyword. You can keep doing that until you are blue in the face and still understand absolutely nothing.
The multiverse is another way of describing the multi-nature of time and position. Heisenberg uncertainty principle makes sense because, Quantum mechanics is about multiple positions, multiple momentum, and multiple times future, present, and past. A photon does interact with itself in the double slit experiment, because it is interacting with it's self in different times. We know that time is not constant, and that an object has an average kinetic energy. Time slows down with increase in energy. This means some of the objects time is different within different areas of the object. It is spread out in position and time. It exists in a multiverse.
tThe how-much mechanics of the wordy word eh, Humpty Dumpty? Do you not understand that "quantum" is merely a latin word for how-much, but wordyword will do as well. Dou never wonder what these wordywords actually m-e-a-n? No, I rather thought not. Why not just chant wordyword, wordyword over and over again? - it can only come to the same thing.
The edge of our universe or the cosmic radiation barrier is like the event horizon off a black hole think of a bubble/balloon it's already popped once we can measure it not expanding anymore that's because it has already ripped the big crunch is on it's way
Oh boy the multiverse. That means that not only the sins I have committed in THIS universe need forgiveness, but the sins I have committed over in the other parallel universe ALSO need God's forgiveness. Do they have New Testaments over there in that other parallel universe? Or do they just have New Age crystals?
Inflation and strings are very probably wrong. Cosmological inflation and string theory are two prominent theories in modern physics, but they face challenges in being proven or experimentally confirmed. Here are the reasons why: Cosmological Inflation: 1. *Lack of direct empirical evidence*: Inflationary theory predicts rapid expansion in the early universe, but this era is inaccessible to direct observation. 2. *Indirect tests are inconclusive*: Cosmic microwave background radiation and large-scale structure observations can be explained by alternative theories. 3. *Multiverse problem*: Inflationary theory predicts a multiverse, making it difficult to test or falsify. 4. *Lack of predictive power*: Inflationary models are highly flexible, making it challenging to make specific, testable predictions. String Theory: 1. *Mathematical complexity*: String theory is a highly mathematical framework, making it difficult to extract concrete predictions. 2. *Lack of experimental evidence*: No direct experimental evidence supports string theory. 3. *Multiverse problem*: String theory also predicts a multiverse, making it challenging to test or falsify. 4. *String landscape problem*: The theory allows for an enormous number of possible solutions, making it difficult to predict specific outcomes. Pitfalls: 1. *Lack of falsifiability*: Both theories are challenging to test or falsify, which is essential for scientific theories. 2. *Over-reliance on mathematical elegance*: The beauty and complexity of the theories can lead to an overemphasis on mathematical elegance rather than empirical evidence. 3. *Speculative nature*: Both theories are highly speculative, and their development has outpaced experimental verification. While these theories have generated significant interest and research, their experimental confirmation remains elusive. Scientists continue to explore new ways to test and refine these theories, but their pitfalls highlight the need for caution and rigor in theoretical physics.
Becuase all oxymoronic terms have round about attributes called hogwash. Infinite universe with unimaginable dimensions is better than obliterating the meaning of Universe. For instance if all that we know is in one bubble and there are thousands more bubbles we don't know, then we don't know the entire universe and never will.
Hi Kirk, we’re not. These are related to the Learning Channel (that’s TLC/Discovery) but we do have a bunch of courses about great books. The course we have about Great books/Books That Matter is: www.thegreatcourses.com/search/great%20books Hope this helps!
M theory is not solvable using perturbation theory, and not well defined. Without knowing the geometry of the extra dimensions (of which there could be 10 to the 500 possible values) I just don't see how you can rectify this to be a viable theory. I don't like the first premise of we have no choice but to accept something outside of the universe may exist. Theists use the same argument for their deity. I know its not nearly the same comparison we have many mathematical proofs that support the hypothesis I just like getting away from any argument religulost people have. This is a really great video though attacking the problems head on in an honest direct way. Inflation theory is right its the best support for sure. Keep the vids coming!
The description on this video says it was uploaded 5 months ago,when the higgs boson was very much discovered. But in the video he says we have yet to discover it.🤥
The dates onsome of Wondrium's videos are highly misleading. Facebook is now Meta, and The Great Courses Plus is now Wondrium. Many of the videos on Wondrium were done some years ago and were on TGCP.
An extravagant edifice built on theories which have no evidence in reality. I do not believe the multiverse is science. Furthermore, like the multiverse, the origin of the one universe we live in suffers from the same lack of evidence and a plethora of mutually exclusive ideas which all challenge the conservation of energy and matter. The idea of multiplying universes ad infinitum when we don't know the mechanism that the universe, we live in is particularly problematic. Physicists are fond of suggesting that the total forces of the universe, subtracting the negative from the positive is zero, purporting that the conservation of energy and matter are not violated. This is a red herring. All of the forces of nature should be added together violating the law of conservation.
Isn't this like the cave theory except for the upper class that is watching the cave interaction is just consciousness shielding itself from fear of the unknown

If GWs lagged behind it would be evidence of multiple universe. If GWs travels at the speed of light without slowing down then it indicated there is no such thing as multiple or parallel universe. If gravitational waves traveled slower than light it would be solid evidence this universe was just one out of countless universes. If gravitational waves didn't travel at the speed of light it would explain why the attributes which make up this universe was finely tuned. It would explain why our universe has existed so long without winking out of existence moments after it began. It would debunk God. The multiple universes would each be random occurrences, set forth in motion after the big bang. Slow gravitational waves would be the holy grail for atheists and their evolutionary cosmology.
So, what did LIGO measure? Every one of the GWs they measured traveled at the speed of light. Researchers went over radio telescope data and determined at the same time and locations of gravitational waves they found a spike in electromagnetic radiation, gamma rays or X-rays. There was no lag between the gravitational waves and electromagnetic waves. Indicating the gravitational waves were not affected by mass in hidden or parallel universes. Multiple universe appear to be science fiction at this point.
It's back to the drawing board I guess.
Shouldn't this be louis carroll. Math proves a multiverse is necessary and the only way to explain time and probability. probability, time and quantum mechanics clearly exist and they would not if multiple time line universes didnot.
Probably a dumb question but that won’t stop me from asking .... doesn’t eternal inflation and the multiverse violate the second law of thermodynamics ?
Eddie, Eternal inflation is a hypothesis while the second law is demonstrated.
@@TheGreatCourses I understand that , but I am asking how do they explain all this extra energy required in Inflation/multiverse ? I never have heard this explanation from its proponents . It seems to me that they need to explain that but it never seems to be addressed . I’m just saying this would appear to be a huge problem .
@@eddiebrown192 I'm not a card-carrying multiverse proponent but if, you are seriously interested in this and actually want an answer, then Sean Carroll has an excellent book called Something Deeply Hidden which goes into this question and other similar questions that a non-professional physicist (but with an active interested mind) would immediately have and in quite some detail. Basically, there are reasonable objections to the multi-verse idea but things like entropy, probability and conservation of momentum and energy are all compatible with it - as you would expect if someone like Sean Carroll is advocating it. Having read his book, I went from being a skeptic to being able to understand that it's a reasonable and valid idea and is not a waste of my time like string theory.
@@alex_madeira _Something Deeply Hidden_ is about the many-worlds hypothesis, which is quite different from the multiverse idea.
How does inflation violate the second law? The bigger the universe, the greater the entropy.
This is not true and is dumb. It shows how one error leads to anothrer. Rejecvting henesis starts the errors. As Twain said heaps of conjecture on a sand of fact. Or something.
Please define multiverse and universe. Can there be a diverse (or biverse), triverse etc?
This all seems philosophical speculation to me
Anything to get out of calling the universe infinite is fair game to the few who reject that argument.
Soon ar later, scientists will be like religious leader. Bring their own 'bible' to proof their god is the correct one 😅. What they get are believer/follower, not science break through.
My vote - Not Science
What is the difference between "Universe" and the "Cosmos"? According to the ancient Greeks?
Listening to life saying "we don't know what life is".
A Multiverse is self contradicting. Please google Multiverse Paradox Cooper
5 clocks all different times 😆
I think the multiverse is real.
I met a man in person who I swear was me and he was pure evil end up rapping someone.
If you seen us we were twins. Dad sad I didn’t have twin
Also by Sean Carroll " Dark matter and Dark energy". Is superb
OMG 😱 I finally found the perfect channel ! Than you
Enjoy learning with us, Vicky!
SORRY FOLKS ! YOU ONLY GET TO LIVE IN ONE UNIVERSE AT A TIME !!!
Every possibility is played out in the multiverses. Why can it not be played out in every galaxy. If there are 2 trillion out there, surely every possibility is accounted for. Why think beyond our own universe, when these possibilities could be happening in our own back yard?
Because there are many more possibilities than just a few trillion.
Even a deck of 52 cards can be arranged in 8x10^67 ways.
That’s way more than the number of atomic particles in our universe.
LOL... Is truly amazing how much we don't know. It is truly amazing how much we have to guess.
And by the way gravity is also a theory. Look it up.
Sounds like there are other attributes of reality that we have potential of exploring ( Example spiritual world, You quite literally Explained about half of it). Think bigger!!!!!!😤💪🤗 how would someone explore the stuff you're talking about. Listening to you talk is like the people in 1400's, Questioning the shape of the Earth Flat or other. If Christopher Columbus sailed the ocean will he fall off the planet? That's the best way I explain it.
Who says that a counterfactual constant of nature COULD be different?
If Sean Carroll was tall, disinterested in physics, and a basketballer... he could have been a basketballer!!! If i was handsome, an actor and George Clooney i could have been George Clooney!
This is in no way science.
11:40 But, if the universe is really infinite, then the amount of energy in "our" universe, is a dust mote in a sunbeam.... And I could just see a bouncing universe being created and instantly self-destructing, only to be reborn again in a fraction of a second and repeating. That would be interesting.
Anyone else reminded of "garden of forking paths"
Just how old is this?? Just posted in Feb but he just said the Higgs Boson hasn't been discovered yet!
How do you know which value for vacuum energy were "natural" ? Wouldn't you need to know a probability distribution ?

Tell the big bangers the truth:- we evolved!
I joined Wondrium and love the content. But you have to sort out the UI. Search function is useless.
Thank you for your feedback and for your suggestion, we appreciate it.
Sean, not sure if you read these comments but I would love to find out about interviewing you for our channel or podcasts.
I believe in a multiverse with multiple dimension... Only hope that beings with higher levels of intelligence will stop observing us and start helping us. We have to be one of the Lowest and worst dimensions with war and Violence. We definitely need help.
My friend you are great but stay away from “why” that you mentioned in your lecture and trust me don’t ask why did I say that. 🤨
Sean Carroll is so awesome and the way he explains the Universe and life seems really easy for him* ..i think Sean Carroll is from an advanced planet and he came here to try and explain all of reality to us, :)
Hi Sean, thank you so much for your kind feedback! We truly pride ourselves on our professors and the depth of our content and are very glad you're enjoying our offerings. Thanks for being a fan!
1/infinity =0
1/ infinity =ZERO
finite number/ infinity=0
This means you will never get a fine tuned universe by chance. The odds are ZERO!
Higgs hasn't been found yet? When was this recorded?
Like a decade ago
I found Sean hypnotic as much as his neckties choice distracting
Only watching this because Rick and Morty
In your intro you said that the multiverse was not observable therefore it was impossible to prove. You can say the same thing about evolution. We have never witnessed an evolutionary transition in the history of mankind. You may find a bone, or a dinosaur egg. But that doesn't mean anything.
Evolution HAS been observed.
Why the need for the multiverse, isn't this universe not big enough
They cannot explain big bang. What caused it? Where did all that energy come from? If one calls the universe the true power of God moreso than the miracles and superstition then everyone gets upset.
Church of the science deniers.
Make wondrium in 2030
The milky way was once thought the only galaxy in the Cosmo...
Extreme observation get us closer to the truth of multiple universes...
Can you not understand that multiple universes is a contradiction in terms- rather like the idea of more than one unique thing? Universe m-e-a-n-s *only-one*.
Either that or it means nothing.
If you have in mind something that is not only-one, then pick another word- a fresh fantasy. If there are more than one unique thing then(neither* of them is unique.
Just chuck away universe or multiverse and speak only of verses.
Go for that and it will become clear to you that verse(uni, or multi) holds no significance for you whatsoever.
You have no idea what a 'verse' is; for you it is no more than a word that evokes no associations whatsoever.
multiverse= lots of somethings but lots of exactly what?-you have not the slightest idea.
Just recognise that fact. instead of multiverse go for wordyword, it comes to e-x-a-c-t-l-y- the same thing.
Sure there are any number of wordywords; so what?
You have no direct immediate personal experience of any of them; you simply keep repeating a mantra: wordyword, wordyword, wordyword. You can keep doing that until you are blue in the face and still understand absolutely nothing.
Lovely movie. Super implementation. Congratulations on the idea. Greetings from Poland and invite you to visit our country
The multiverse is another way of describing the multi-nature of time and position.
Heisenberg uncertainty principle makes sense because, Quantum mechanics is about multiple positions, multiple momentum, and multiple times future, present, and past. A photon does
interact with itself in the double slit experiment, because it is interacting with it's self in
different times. We know that time is not constant, and that an object
has an average kinetic energy. Time slows down with increase in energy.
This means some of the objects time is different within different
areas of the object. It is spread out in position and time. It exists in a multiverse.
tThe how-much mechanics of the wordy word eh, Humpty Dumpty?
Do you not understand that "quantum" is merely a latin word for how-much, but wordyword will do as well.
Dou never wonder what these wordywords actually m-e-a-n?
No, I rather thought not.
Why not just chant wordyword, wordyword over and over again? - it can only come to the same thing.
How about Multi Gods?
The edge of our universe or the cosmic radiation barrier is like the event horizon off a black hole think of a bubble/balloon it's already popped once we can measure it not expanding anymore that's because it has already ripped the big crunch is on it's way
Oh boy the multiverse. That means that not only the sins I have committed in THIS universe need forgiveness, but the sins I have committed over in the other parallel universe ALSO need God's forgiveness. Do they have New Testaments over there in that other parallel universe? Or do they just have New Age crystals?
😂😂
Inflation and strings are very probably wrong.
Cosmological inflation and string theory are two prominent theories in modern physics, but they face challenges in being proven or experimentally confirmed. Here are the reasons why:
Cosmological Inflation:
1. *Lack of direct empirical evidence*: Inflationary theory predicts rapid expansion in the early universe, but this era is inaccessible to direct observation.
2. *Indirect tests are inconclusive*: Cosmic microwave background radiation and large-scale structure observations can be explained by alternative theories.
3. *Multiverse problem*: Inflationary theory predicts a multiverse, making it difficult to test or falsify.
4. *Lack of predictive power*: Inflationary models are highly flexible, making it challenging to make specific, testable predictions.
String Theory:
1. *Mathematical complexity*: String theory is a highly mathematical framework, making it difficult to extract concrete predictions.
2. *Lack of experimental evidence*: No direct experimental evidence supports string theory.
3. *Multiverse problem*: String theory also predicts a multiverse, making it challenging to test or falsify.
4. *String landscape problem*: The theory allows for an enormous number of possible solutions, making it difficult to predict specific outcomes.
Pitfalls:
1. *Lack of falsifiability*: Both theories are challenging to test or falsify, which is essential for scientific theories.
2. *Over-reliance on mathematical elegance*: The beauty and complexity of the theories can lead to an overemphasis on mathematical elegance rather than empirical evidence.
3. *Speculative nature*: Both theories are highly speculative, and their development has outpaced experimental verification.
While these theories have generated significant interest and research, their experimental confirmation remains elusive. Scientists continue to explore new ways to test and refine these theories, but their pitfalls highlight the need for caution and rigor in theoretical physics.
And you know this how???
@@karagi101 I answered in my comment by expanding it.
@@buca512boxer Inflation makes predictions that match what we see in our universe.
@@karagi101 of course not. You are wrong.

One of the best Presentation. Amazing.
I've never understood why multiverses are depicted as round. And I still don't.
Becuase all oxymoronic terms have round about attributes called hogwash. Infinite universe with unimaginable dimensions is better than obliterating the meaning of Universe. For instance if all that we know is in one bubble and there are thousands more bubbles we don't know, then we don't know the entire universe and never will.
Are the great courses somehow related to the same great books ...as in the three books sitting under that clock on the desk behind him?
Hi Kirk, we’re not. These are related to the Learning Channel (that’s TLC/Discovery) but we do have a bunch of courses about great books.
The course we have about Great books/Books That Matter is: www.thegreatcourses.com/search/great%20books
Hope this helps!
M theory is not solvable using perturbation theory, and not well defined. Without knowing the geometry of the extra dimensions (of which there could be 10 to the 500 possible values) I just don't see how you can rectify this to be a viable theory. I don't like the first premise of we have no choice but to accept something outside of the universe may exist. Theists use the same argument for their deity. I know its not nearly the same comparison we have many mathematical proofs that support the hypothesis I just like getting away from any argument religulost people have. This is a really great video though attacking the problems head on in an honest direct way. Inflation theory is right its the best support for sure. Keep the vids coming!
I believe there is life outside the solar system.
The atmosphere is not opaque, just relatively transluscent.
He was talking about a hypothetical world in which the atmosphere was opaque.
The description on this video says it was uploaded 5 months ago,when the higgs boson was very much discovered.
But in the video he says we have yet to discover it.🤥
The dates onsome of Wondrium's videos are highly misleading. Facebook is now Meta, and The Great Courses Plus is now Wondrium. Many of the videos on Wondrium were done some years ago and were on TGCP.
@@GeezerBoy65 Thanks.

An extravagant edifice built on theories which have no evidence in reality. I do not believe the multiverse is science. Furthermore, like the multiverse, the origin of the one universe we live in suffers from the same lack of evidence and a plethora of mutually exclusive ideas which all challenge the conservation of energy and matter. The idea of multiplying universes ad infinitum when we don't know the mechanism that the universe, we live in is particularly problematic. Physicists are fond of suggesting that the total forces of the universe, subtracting the negative from the positive is zero, purporting that the conservation of energy and matter are not violated. This is a red herring. All of the forces of nature should be added together violating the law of conservation.
Isn't this like the cave theory except for the upper class that is watching the cave interaction is just consciousness shielding itself from fear of the unknown
